Trending WhatsApp Remote Code Execution Vulnerability that let the Hackers hack Android Devices by using Just a GIF Image

 

 

A new WhatsApp vulnerability that has been discovered by a security researcher. In this vulnerability, a hacker can compromise user chat sessions, files, and messages through malicious GIFs. Today, this short looping clips, GIFs are everywhere – on social media, on your messaging applications, on your chats, helping users to express their emotions, making people laugh and make fun. Even people make gifs of themselves.

WhatsApp Messenger is a freeware, cross-platform messaging service owned by Facebook. It allows users to send text messages and voice messages, also make voice and video calls, and share images, documents, user locations, contacts, and other media and has a billion users across the globe. There is this security vulnerability, and it remained unpatched for months. And it potters that if this
vulnerability is exploited by the attacker then it could have the attacker to hack the device and steal user data. It is found in Android versions below 2.19.244.

What is WhatsApp RCE Vulnerability?

RCE is Remote Code Execution Vulnerability. It is a double-free vulnerability that lies in the Gallery view implementation. A double-free vulnerability is when the free() parameter is called twice on the same value and argument in the application. And in this case, the memory may leak or become corrupted, giving attackers all the
opportunity to overwrite elements. And it is generally used by developers to develop a preview whenever a user wants to upload or send the file to people.
The overwriting of the elements can simply happen with the payload which will be executed in the WhatsApp content. Which will give the permission to read and access the SDCard and message database? The Malicious code/Payload will have all the permissions of the WhatsApp like, audio recording, accessing the camera, accessing photos, contacts and files/documents. Even the sent box which will have all the data.

How is WhatsApp RCE Vulnerability exploited?

This vulnerability is exploited by the hackers, wherein the hacker needs to send a specially crafted malicious GIF file to targeted Android phones via any online communication channel and then wait for a gallery by tapping the Paperclip Button or the attachment icon in WhatsApp.

The target here said, “WhatsApp shows the preview of all media like photos, GIFs including the ones that are received. And due to which double-free vulnerability and RCE exploit is triggered.” The security flaw is patched with CVE-2019-11932, the exploit is titled as WhatsApp 2.19.216 – Remote Code Execution
The vulnerability has been patched in the new updates of WhatsApp. But if the users are using the versions 2.19.244 or below than that, then it is highly recommended the users to update their WhatsApp app to the latest version from the Google Play Store as soon as possible.

HOW TO IMPROVE YOUR PYTHON SKILLS ?

Python is not mostly used language but it is well designed as compare to other language and delivers many features that can help a newcomers to became a good developer and establish developer can switch to python. As compared to other language like C , C++ and java Python is constantly growing.  As a language, it is aspect-oriented which means there are modules with different functionality. So first the developer has to create the modules and afterwards, based on the “if then” action, depending on the user’s action, the algorithm triggers a particular block and brings the result. The Python language has a variety of uses in the software field, but developers are mostly dealing with backend components, connecting applications and giving support to frontend developers in web applications. Of course, you might create applications with use of different languages but pretty often Python is the language chosen for it – and there are reasons for that!

 

PYTHON SKILLS

 

Lets talk about the skills now ! What are the technical and soft skills you need became a good developer ?

PYTHON :

Quite obvious, Python is the main language which you are going to use at work to finish the project. Fortunately, if you are a developer but focused on other languages, the language switch might come with ease. Python is the general-purpose programming language with constantly increasing demand for. Due to relatively easy learning path, it is beginner-friendly and definitely experienced-developer-friendly as well! There is no need to know each module but at least, regardless of basic syntax and semantics, the differences between Python 2 and 3. A good Python dev can smoothly adjust to those, however, it is not a big deal because the distinction is rarely required. It is also advisable to know python’s data structures. While you do not have to learn by heart how to implement a b-tree, knowing what lies under the hood of a set, dict or list will come in handy both in small and big projects.

 

Frameworks for Python

 

Frameworks for Python :  

Knowing Python frameworks is a must, however, it doesn’t mean that a Python developer has to know them all. Depending on the project you may be asked to know one or another, used are Django, Flask, and CherryPy.  Undoubtedly, if you already know Python, you had a chance to work with at least one of the most popular frameworks! The basic and well-defined structure offered by the frameworks is usually appreciated by devs while figuring out the core logic of the application.

 

 

ORM library familiarity

 

ORM library familiarity :  

Using and connecting application through an ORM (Object Relational Mapper) like SQLAlchemy, Django ORM and so on is easier, faster and more efficient than writing SQL – which means, more likely it is preferred by the team. Good to have it in your skillset!

 

Basic knowledge of front-end technologies :  

Very often any python developer has to cooporate with frontend team to make match the server side with the client-side . Now its important to understand how the frontend works , what’s possible and what’s not , how the application is going to appear. But Of course, in proper agile software houses, there is also a UX team, project/product manager and SCRUM master to coordinate the workflow. It doesn’t mean that a frontend is a must-know for a Python dev but definitely, in some projects, this kind of knowledge and experience is more than welcome.

 

AI and Machine Learning  :

This will be a huge plus for you if you know what is it about! AI and Machine Learning (as well as deep learning) are constantly growing as a field – Python is a perfect programming language for that. If you are into data science, then definitely digging in the Machine Learning topic would be a great idea.

 

Python Libraries :

Libraries make a developer’s life easier, the team’s workflow more efficient and task’s execution way faster. Depending on the projects nature, it is better to know the libraries which are going to help you in everyday work. Python, as a community-based programming language, has an answer to almost any possible request. Some of the library function like Requests , Scrapy , Wxpython , Pillow , SQLAlchemy and so on.

 

Version control :

Keeping track of every change made to the file to later on source the code is a must-know for each developer! In most of the job offers you can see this as a requirement – thankfully it is not difficult to get familiar with and if you have been coding since a while, you have properly set your GitHub and terms like “push, fork, pull, commit” are not random words for you.

 

Communication :

Let’s not forget that a developer’s work is not only typing the lines of code! In best software development firms the teams are made out of amazing programmers which work together to achieve the final goal – no matter if it means to finish the project, to create a new app or maybe to help a startup skyrocket. However, working in a team means that a developer has to communicate well – not only to get the stuff done but also to keep the documentation clear so others can easily read and follow the thinking path to fully understand the idea.

Benefits of learning java programming language

 

Java is a general-purpose, high-level programming language developed by Sun
Microsystems. who initiated the language in 1991.
Java is a widely-used programming language. It is also among the most favored for the development of edge devices and the internet of things.
It can also be used to build a small application module or applet for use as part of a webpage.Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network.

Why Became Popular?

Java source code is compiled into Java byte code, which can run anywhere in a network, on a server or on a client environment that we are called Java virtual machine (JVM).
The JVM interprets convert to byte code into code that will run on computer hardware. In contrast, most programming languages, such as COBOL or C++, will compile code into a binary file. Binary files are platform-specific. The JVM includes an optional just-in-time (JIT) a compiler that dynamically compiles byte code into executable code. In many cases, the dynamic JIT compilation is faster than the virtual machine interpretation.

Features of Java

Object-oriented Concept

 

An object is made up of data as fields or attributes and code as procedures or methods. An object can be a part of a class of objects to inherit code common to the class. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.

Exception Handling in Java

To make a robust and well-behaved application, Java offers an exception handling mechanism using to maintain the normal execution control flow when an exception occurs. The Java exception-handling mechanism contains five keywords: try, catch, throw, throws, and finally.

Interpreted language

Java byte code is translated on the fly to native machine instruction & it’s not stored anywhere. The development process is more rapid and analytical since linking is an incremental and light-weight process.

 

Benefits of Java

Data Security

Unlike C++, Java does not use pointers concept, which can be unsecured. but in java environment Data converted to byte code, this code is not possible to read by humans. Secure coding is the practice of developing computer software in a way that guards against the accidental introduction of security vulnerabilities. Defects, bugs, and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities.

Desktop GUI applications

A java GUI application uses the standard java components GUI set, swing & is deployed to the desktop. Java Swing is a lightweight graphical user interface that means a GUI toolkit that includes a rich set of widgets. It includes packages that let you make GUI components for your java applications & it is platform-independent.

Scientific Applications

Java supports scientific application development, because of it is security very powerful, robustness features, much scientific application based on java technology.
Web Applications These are the main component of java which helps to develop the web-based applications. We can develop can kind of web-based application which helps with these technologies.

Mobile Applications

In Today’s world, every second phone has an android OS which is based on Java. Java is the technology of choice for building applications using managed code that can execute on mobile devices.

AWS: Expectation vs. Reality

 

 

Amazon Web Services(AWS) is a cloud service from Amazon, which provides services in the form of building blocks, these building blocks can be used to create and deploy any type of application in the cloud. These services or building blocks are designed to work with each other, and result in applications that are sophisticated and highly scalable.

AWS is hitting the markets big time. Today the stability and demand of engineers in this niche are at its all-time high. However before diving in it completely it is imperative to understand what exactly it does and how beneficial it is. Putting it in simpler words it is important to understand the difference between expectations and reality. There is no denial of the fact that more and more companies are now moving towards cloud-based solutions. This huge shift of pendulum has benefited AWS tremendously as no other solution comes close to what they offer. This is the reason why engineers today are enrolling in AWS Training in Kolkata to better understand it.

 

 

 

Set-Up

Expectation: Setting it up will not be difficult as Amazon wants more and more companies to use its solution. So they would have made it as simple as possible.

Reality: Yes Indeed, setting it up is actually quite simple. All kinds of tutorials are available online to ensure engineers are able to go about their stuff smoothly. From running the database to hosting a website there is a tutorial available for each of these services.

 

Cost

Expectation: Since it is an Amazon product so it will be on a higher side of the budget. Also at the minute, it is enjoying a good monopoly so amazon can price it as per its liking.

Reality: Contrary to the expectations, AWS is actually very cost-effective. Not only you will be able to save money by notching up your productivity but overall also the cost of its deployment and usage is not much as compared to other available marketing solutions.

 

Security

Expectation: No doubt cloud based solutions are effective but you have to compromise on security. AWS security can easily be breached, so developers have to be careful while using it.

Reality: When it comes to security, they are second to none. Amazon at its own end has done quite a bit to ensure proper security to its users. No doubt developers have to be careful while deploying their solutions still services offered by Amazon in this regard is awesome, all the more reason why it is a perfect time to be in AWS Training.

 

Future

Expectation: AWS is good and in demand but this is the best it can offer so it is good to get into in now and look for options later

Reality: Though AWS enjoys a great market hold but its story doesn’t end here. In fact, every few months they are adding on to their current set of services. Working hard to their already successful system and helping their customers to grow even bigger. The best thing about these solutions is the more you use them the better they get. This is the reason why more and more people are using it. These solutions are going to stay, so if you are interested to join an AWS Course in Kolkata today and make a difference.

 

Conclusions:

AWS offers the largest global footprint in the market. No other cloud provider offers as many regions with multiple Availability Zones, with 69 Availability Zones (AZs) within 22 geographic regions around the world, and announced plans for 10 more AZs and three more AWS Regions in Indonesia, Italy, and South Africa.

AWS Regions each have multiple AZs that are physically separated and isolated from each other and are connected by low latency, high throughput, and highly redundant networking. The AWS Region/AZ model has been recognized by Gartner as the recommended approach for running enterprise applications that require high availability.


Introduction to DevOps

Introduction to DevOps

 

DevOps is not a tool or a team, it is the process or a methodology of using various tools to solve the problems between the Developers and the Operations team in an organization, hence the term came “Dev-Ops”.

The development team always had the pressure of completing the old, pending work that was considered faulty by the operations team. With DevOps, there is no wait time to deploy the code and getting it tested. Hence, the developer gets instantaneous feedback on the code, and therefore can close the bugs, and can make the code production ready faster!

 

The business Values of DevOps

 

2018 was proclaimed the year of enterprise DevOps by Forrester, as more than 50% of enterprises worldwide have already done their DevOps transformation or are in the process of it. Here We will explain this below, with some examples of how DevOps helps companies across various industries succeed.

In short, implementing DevOps best practices and workflows helps businesses save time and money, increase software lifecycle predictability, build a corporate culture around innovation and keep motivation levels high. We will discuss it in detail.

DevOps Saving time and money: DevOps principles of IaC, CI, and CD help ensure the uniformity of task scenarios and infrastructure immutability, so automation becomes 100% efficient and helps greatly reduce the amount of time and effort spent on routine and repetitive tasks.

DevOps Training in Kolkata

 

 

DevOps Tools

 

Tools you’d use in the commission of these principles. In the DevOps world, there’s been an explosion of tools in release (Jenkins, Travis, TeamCity), configuration management (puppet, chef, ansible, cfengine), orchestration (zookeeper, Noah, Mesos), monitoring, virtualization and containerization (AWS, OpenStack, vagrant, docker) and many more. While, as with Agile, it’s incorrect to say a tool is “a DevOps tool” in the sense that it will magically bring you DevOps, there are certainly specific tools being developed with the express goal of facilitating the above principles, methods, and practices, and a holistic understanding of DevOps should incorporate this layer.

 

 

Most Influential Benefits Of DevOps

 

Speed: DevOps practices let you move at the velocity you need to innovate faster, adapt to changing markets better, and become more efficient at driving business results.

Rapid delivery: When you increase the pace of releases, you can improve your product faster and build a competitive advantage.

Reliability: DevOps practices like continuous integration and continuous delivery can ensure the quality of application updates and infrastructure changes so you can reliably deliver at a more rapid pace while maintaining an optimum experience for end-users.

Improved collaboration: Under a DevOps model, developers and operations teams collaborate closely, share responsibilities, and combine their workflows. This reduces inefficiencies and saves time.

Security: You can adopt a DevOps model without sacrificing security by using automated, integrated security testing tools.

 

 

 

 

Conclusion

 

DevOps is a revolution that aims at addressing the wall of confusion between development teams in big corporations having large IT departments where these roles are traditionally well separated & isolated.

Now, what about smaller corporations that don’t necessarily have split functions between developers & operations?

Adopting DevOps principles & practices, such as deployment automation, continuous delivery and flipping still bring a lot.


Why Shopping Mall is being targeted by Hackers?

Why Shopping Mall is being targeted by Hackers?

Last few years were critical for many companies in the E-commerce sector, due to the high amount of cyber-attacks and emerging threats.

 

Study of Business Insider shows that for the period of one year at least 16 separate security breaches have occurred at large retailers. Many of them are due to security flaws in payment systems.

 

Recent report by shape Security showed that many people that log in to a retailer’s E-commerce site are hackers using stolen data. This is the highest percentage of any sector. Some of the largest retailers like Adidas, Macy’s, Best Buy, Forever 21 and others have been affected. Large amount of compromised data is being sold on “dark web”, including databases with personal data, credit card numbers and confidential corporate data, used by the competitors.

 

Lets See What CEO of Indian Cyber Security Solutions, Mr. Abhishek Mitra has said about this

 

 

 

Another issue in the sector is being caused by the high amount of IoT devices, which allow more and better ICMP and DDOS attacks to be crafted. Many vulnerabilities are caused due to input validation errors, client side gaps, vulnerabilities in database servers or network related vulnerabilities.

It is very important for an E-commerce organization to provide layered security infrastructure, as well as to perform regular assessments in order to check the security of their systems, networks, web and mobile applications and employees.

GDPR and other law requirements provide a strong challenge for most organizations, operating with personal data.

In the white paper we will observe the following topics:

  • Some of the issues that you can face.
  • Famous attacks in the sector.
  • Protection mechanisms.
  • Basic security measures.

 

 

Attacks Shopping mall industry have seen in past

 

Malware

Malware is malicious software, developed by malicious hackers to gain access or cause damage to a computer system or network, often without the knowledge of the affected user.
Malware is often called ‘computer virus’, although there are big differences between these types of malicious software.

Magento and other E-commerce platforms are particularly vulnerable to widespread malware infections due to their prevalence in the market. Malware can perform an extremely wide range of activities. It can use your computer as part of a botnet in order to launch DDOS attacks, steal credit card numbers or sensitive account information from the users of your website. A famous malware, intended to target Magento sites, had the functionality to extract credit card information and store it in images so that the attacker could easily access it without raising any alarms.

 

 

 

 

Log Injection

Log files can be used by an attacker to inject malicious content or forge log entries if there is a vulnerability which allows unvalidated user input to be written in the logs.

Log injection vulnerabilities occur when the data comes from an untrusted source or the data is written to an application or system log file.
Log files are typically used by the applications to store a history of events or transactions which could be later reviewed. Logs could also be used for statistics gathering, or debugging. Depending on the application’s functionality, log files could either be reviewed manually or with the help of automated tool that automatically reads logs and searches for trending information or important events.

Log files might get corrupted if an attacker can supply data to the application that is subsequently logged verbatim.

 

 

 

 

Bad bots

Bots have many names – crawlers, spiders, Internet robots, web bots and more. They are frequently used to perform repetitive jobs and simple tasks, like indexing a search engine. However they often come as part of a malware. They are used to gain full control over a computer system. Some of them have the functionality to infect the host and connect back to a CNC (command and control) central server(s), which could be used to control a network of compromised computers and hosts.

 

  • Fraud – Bots can prevent your legit users from purchasing items by sending many purchasing requests for an item in order to make it appear out of stock for your clients. They can also list your items for sale in other sites at a lower price. Bots could also be used to attempt to brute-force the credentials of your consumers. In case of a successful login they can also resell the information to a third party. In case that someone is able to use the credit card of your clients, that could ruin the trust among them.

 

  • Price Scraping – Price scrapping is a technique used to craw an online store for its prices along with product catalog information, with the help of bots. It is often used by competitors in order to steal the dynamic pricing of a website, which is extremely important in the E-commerce platforms. The reason for this is that many consumer-buying decisions and revenue forecasts rely on the real-time dynamic pricing. Such hacking method would allow the competitors to set prices lower than baseline prices in the marketplace and therefore attract more consumers.

 

  • Analytics Bots can have a high impact on the analytics of your selling campaign, by imitating human behavior. Many of them use scripting code like JavaScript, which is also the mechanism most analytics tools are using to bounce rate, conversion rate, count page views and more. Such attacks could convince you to spend more money on advertising, compromise your metrics and lower your conversion rate.

 

Phishing

Hackers may try to attack your E-commerce business by launching phishing campaigns. For the purpose they might craft fake emails, phone calls and SMS messages. Hackers can also inject malicious JavaScript snippets to checkout pages in popular E-commerce platforms like Magento, Woo Commerce, PrestaShop and others. Many merchants use PayPal as a payment method, which means that if PayPal account gets suspended it will limit the consumer’s ability to purchase new items. That makes merchants to consider important if they receive an email claiming to suspend their account due to malicious or unusual activity. If they lack security awareness, merchants may follow a fake page link and according to the instructions provide their login credentials. They can also download, complete and submit invoices, bills and proposals in the form of attachment, which will provide the cybercriminal with their user names and passwords and full access to the merchant’s PayPal account. The attachment could also auto-install malicious software on the victim’s computer.

 

DDoS

 

A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. DDoS attacks achieve effectiveness by utilizing multiple compromised computer systems as sources of attack traffic. Online stores are especially vulnerable to those attacks especially during discount periods, like Black Friday. However, there are easy to implement measures, to protect against such type of attacks.

 

Vulnerabilities in firewall

 

Firewalls are usually important assets of every network security infrastructure. Their job is to restrict the inbound do outbound access and vice versa to specific IP addresses and networks. Firewall vulnerability might be caused because of an error made during firewall design, implementation, or configuration that can be exploited to attack the trusted network behind the firewall. Some common firewall vulnerabilities and misconfigurations include:

  • Allowed ICMP traffic.
  • Blocking traffic, instead of dropping it.
  • Lack of port restriction.
  • Unrestricted access to specific IPs and networks.
  • Unnecessarily open TCP and UDP ports.

 

 

Preventive measures in Shopping Mall industry:

  1. Trademark your company name and logo
  2. Use a trusted ecommerce platform
  3. Use HTTP with SSL = HTTPS
  4. Make sure your site is PCI DSS compliant
  5. Keep your site updated
  6. Require strong passwords
  7. Know the signs of fraud

Why IOT industry is being targeted by Hackers?

We are living in a connected world, where nearly all devices are becoming connected.

The internet of things (IoT) is coming up in a big way and with amazing opportunities – but it also brings serious security threats.

IoT connects physical devices, so the hacking of IoT devices has the potential to cost human lives.

Further implications can be access to unauthorized and potentially confidential data that can then be used for other crimes.

 

Let Us See what our CEO, Abhishek Mitra have to say about IoT Hacking:

 

What type of attacks IOT based industry have seen in past?

 

 IoT devices have potential security vulnerabilities like weak passwords and other poor default security settings, lack of encryption when devices communicate over the network, and poor (or non-existent) user-serviceable device management.

Due to these vulnerabilities, many IoT devices are surprisingly easy to attack.

 

Ransom attack

Researchers at cybersecurity firm McAfee called the past months “the quarter of data dumps” in an alarming report released on Wednesday. 

The 40-page survey of the security landscape found more than 2.2 billion stolen account credentials were made available on the cybercriminal underground this quarter and hackers had even figured out ways to break into Wi-Fi enabled coffee makers.

“The impact of these threats is very real,” said Raj Samani, McAfee fellow and chief scientist.

“It’s important to recognize that the numbers, highlighting increases or decreases of certain types of attacks, only tell a fraction of the story. Every infection is another business dealing with outages, or a consumer facing major fraud. We must not forget for every cyberattack, there is a human cost.”

IOT BOTNET ATTACK

A new IoT botnet named Ares is infecting Android-based devices that have left a debug port exposed on the Internet.

Among this botnet’s most common victims are Android set-top boxes manufactured by HiSilicon, Cubetek, and QezyMedia, cyber-security firm WootCloud said today. Check Out Here

What kind of action or preventive measures have saved the industry from being hacked and face humiliation?

 

  1. Learn how to maintain the security of IoT devices.Consumers need to protect their IoT devices the same way they would their smartphones, tablets and home computers. Look for ways to set strong passwords, reading the manuals for instructions on how to lock down these devices.

 

  1. Clean out old apps.Many of us tend to keep apps indefinitely, even if we don’t use them. Check your devices periodically and delete apps you no longer use.

 

  1. Own your online presence.Understand what information your devices collect and how they it is managed and stored.

 

  1. Do your research.Before you purchase an IoT device, do a search to see if it has had security problems with it and if it can be easily hacked.

 

  1. Change the default setting on the home router.This is worth reiterating: Strong passwords on home routers can prevent the type of DDoS that happened last Friday to Dyn.

Why healthcare industry is being targeted by Hackers?

Why healthcare industry is being targeted by Hackers?

Health care is one of the most important industries. While other sectors focus on products people want, the medical field provides a service the public actually needs. Sadly, this altruism isn’t rewarded. Hackers are increasingly targeting these institutions with their nefarious plots, and a lot of patients are getting caught in the crossfire. The problem here is that quite a lot of people don’t understand the threat facing the health care industry right now. News reports of retailers and financial institutions getting hacked have people thinking these are the most targeted sectors, but this just isn’t true. Analysis of 10 years of cyber-attack data actually points to health care as being the most hacked industry out there. Clearly, hackers have a lot of motivation to go after these kinds of institutions. However, hospitals don’t really come to mind when most people think of an easy buck.

 

Why hackers target Hospital or healthcare industry 

Healthcare organizations collect and store vast amounts of personal information, making them a major target for cyber-criminals. This valuable data can be used for identity theft, says Peter Carlisle, head of EMEA at cloud and data security company Thales security. “In the US, stolen personal health insurance information can be used by criminals to obtain expensive medical services, devices and prescription medications, as well as to fraudulently acquire government benefits like Medicare or Medicaid.”

Healthcare breaches are especially serious because personal data can, in some cases, mean the difference between life and death. For example, says Carlisle, it could cause medications to become mixed up – or people might fail to get treatment for conditions such as diabetes. Making things worse, healthcare providers often struggle to find room in tight budgets to invest in new IT systems, leaving them vulnerable. “Compliance issues are commonplace in healthcare too, where organizations need to meet stringent requirements of governing bodies such as HIPAA,” Carlisle adds.

NOW LET US SEE WHAT CEO OF ICSS HAD SAID ABOUT THIS TOPIC

 

 

 

What type of attacks healthcare industry have seen in past?

 

Security concerns are growing exponentially in healthcare, as hospitals become the most financially lucrative targets for cyber-attackers. The main reason for the increase in cyber-criminals targeting the healthcare industry is for the ease with which hackers can pull vast amounts of personal data from aged systems that lack necessary security features.

THE “KANE” INCIDENT

 The theft or even alteration of patient data had been a looming menace long before Dutchman “Kane” compromised Washington University’s Medical Center in 2000. The hospital at the time believed they had successfully detected and cut off the attack, a belief they were rudely disabused of six months later when Kane shared the data he’d taken with Security Focus journalist Kevin Poulsen, who subsequently published an article describing the attack and its consequences. This quickly became global news. Kane was able to stay hidden in the Medical Center networks by allowing his victims to believe they had expelled him. He did this by leaving easily discoverable BO2K Remote Access Trojans (a tool developed by the hacker group, “Cult of the Dead Cow” and popular around the turn of the century) on several of the compromised servers while his own command and control infrastructure was somewhat more discrete. The entire episode is well documented online and I suggest you read up on it, as it is both an excellent example of an early modern APT and a textbook case of how not to deal with an intrusion—procedurally and publicly.

Ransomware

Notable Example: Presbyterian Medical Center

 

One of the more common types of attack occurring in 2016 has been ransomware. When this occurs, a hacker infiltrates the network and accesses data. It is then copied over and encrypted. Once encryption is complete, the original data will be deleted and data will be inaccessible until a ransom is paid. This usually results in an inability to access the EHR while the application is locked down; any communication has to be completed via telephone calls or faxes, resulting in an overall delay in patient care.

This recently occurred at Hollywood Presbyterian Medical Center in February 2016. Hackers used malware to infect the computers at the facility and stopped communication between devices. They demanded a ransom of $17,000 to restore their applications back to fully functional. Physicians were unable to access medical records for more than a week and they were forced to utilize paper record keeping until the facility ultimately paid the requested amount. While Hollywood Presbyterian stated that patient care was not impacted, patient history could not be viewed and test results could not be shared from lab work, X-rays, and more. It is believed that this occurred because an employee opened an infected email or downloaded the malware from a pop-up ad which brought the virus onto the network. A few weeks later, a group of Turkish hackers claimed responsibility for the attack which may mean that the motivation of the attack was not to steal patient data for financial means but as a political statement.

 

 

 

 

What kind of action or preventive measures have saved the industry from being hacked and face humiliation?

These days most of our important transaction happens over internet. The hackers have numerous ways to steal important data which is then put to misuse. Below there are five most common ways your data can be stolen and the precaution you can take to stay safe:

 

1. Phishing

 

Phishing is a fake email masquerading as legitimate. Hackers create phishing emails through which they intend to steal your confidential information like passwords and bank account details. This kind of email appears to have come from a well-known person or organization like your bank or company that you work for. These emails generally try to create an urgency or panic to trick users into giving out their personal details. For example, you receive an email from your bank saying that your ATM card has been disabled and you need to confirm your card number or your Aadhaar number to re-activate it. A victim who has received this email might think that it is from a legitimate source when in reality this email has been sent from a malicious hacker trying to steal your confidential information.

 

 

HOW TO PREVENT IT:

Look for spelling or grammatical errors in domain names or email addresses. Cyber criminals also often use email addresses that resemble the names of well-known companies but are slightly altered. For example, accounts@gmall.com instead of accounts@gmail.com (“l” instead of “i”).

Think twice before clicking any links. If you see a link in a suspicious email message, don’t click on it. Instead, hover your mouse on the link to see if the URL matches the link that was provided in the message.

Cyber criminals often use threats that your security has been compromised or your account has been blocked. Don’t fall for such tricks. Take your time to assess the situation.

 

2. Insecure Network:

Connecting your system or device to an insecure network can create the possibility of a hacker gaining access to all the files on your system and monitoring your activity online. A hacker in control of your system can steal passwords of your social accounts, bank accounts and even inject malware on authentic websites that you trust. With programmes freely available on the Internet, anyone can sit in a car outside your home and access your critical files, accounting data, usernames and passwords, or any other information on the network. A competitor in possession of such in-depth knowledge of your official documents can be a damaging or even fatal threat to your business.

 

HOW TO PREVENT IT:

Never connect to open Wi-Fi networks that you can’t trust. Just because it’s free, it doesn’t mean it’s safe too. When in a cafe with a Wi-Fi facility, ask the staff for the Wi-Fi you can connect to instead of randomly connecting to any open network.

If you are using a public Wi-Fi, avoid performing any bank transactions or accessing any critical information while being connected.
Use strong encryption like WPA2 on your home and office Wi-Fi router instead of Open or WEP security as these can easily be hacked.

Your security is in your own hands. Stay cautious and alert at all times. Always remember, someone, somewhere is trying to hack you and basic security practices mentioned above can protect you from most hacks.

 

3. Insecure API

There is a big misconception that every app available on Google Play store or Apple store is safe and legitimate. However, this is not the case. Not every app available on these stores is safe for users. Some of these apps may contain malicious code that can put your privacy at risk.

 

HOW TO PREVENT IT:

Always check the permissions before downloading an app.

Check reviews and ratings.

Avoid downloading an app if it has less than 50,000 downloads.

Do not download apps from third party app stores.

Never download pirated/cracked apps.

 

4. Malware:

Malware is a malicious software that is written with the intent of compromising a system and stealing the data available on the system. These programmers can perform a variety of functions some of which include stealing or deleting sensitive data, modifying system’s core functionalities, and secretly tracking the victim’s activities. There are various factors that can lead to the installation of malware in your system. One is running an older or pirated version of an operating system which is not safe or updated and thus vulnerable to attacks. Clicking on unknown links or installing fake/pirated software can also lead to downloading of malicious programmers.

 

HOW TO PREVENT IT:

Use a legitimate anti-virus software.

Do not download any fake software as there are chances it may contain malware.

Never click on fake antivirus pop-ups that are generated from websites.

Always keep your operating system updated.

Never download pirated apps/software as they always contain some kind of malware.

 

5. Physical Threads:

A physical threat is any threat to your sensitive information that results from other people having a direct physical access to your devices like laptops, hard drives and mobile devices.

Physical security threats are often underestimated in favor of technical threats such as phishing and malware. Physical device threats occur when someone is able to physically gain access to your confidential data like data gathered from stolen devices.

Physical security breaches can happen at your workplace or even at your home. For example, someone could get hold of your confidential files that they are not supposed to see or access an unattended system which is not password-protected.

 

HOW TO PREVENT IT:

 Be careful how you store confidential information. Use encrypted computer hard drives, USBs, etc if they contain sensitive information.
Never write your passwords on a post-it or notepad.

Never leave your system unattended. Always protect it with a strong password.

Don’t leave your phone unlocked and unattended.

Make sure proper backup and remote wipe services are enabled in case you lose your device.
