Social Engineering - ICSS

The term "Social Engineering" refers to a wide range of malevolent behaviours carried out through human relationships. It employs psychological manipulation to dupe users into committing security errors or disclosing sensitive information.

Social engineering assaults can be carried out in one or more steps. A perpetrator first analyses the target victim to obtain background information, such as potential points of entry and lax security standards, that will be required to carry out the attack. The attacker then proceeds to acquire the victim's trust and give stimuli for further acts that violate security norms, such as disclosing sensitive information or granting access to key resources.

What makes social engineering so hazardous is because it relies on human error rather than software and operating system flaws. Legitimate user errors are far less predictable, making them more difficult to detect and prevent than malware-based intrusions.

Social Engineering Attack Techniques

Social engineering assaults can take many different forms and can be carried out everywhere there is human interaction. The five most prevalent types of digital social engineering attacks are as follows.

Baiting

Baiting attacks, as the name implies, use a false promise to spark a victim's avarice or curiosity. They trick people into falling into a trap that takes their personal information or infects their computers with malware.

The most despised kind of baiting involves the use of tangible media to disseminate malware. For example, attackers may place the bait (usually malware-infected flash drives) in high-traffic areas where potential victims are bound to see them (e.g., bathrooms, elevators, the parking lot of a targeted company). The bait has a genuine appearance, such as a label that presents it as the company's payroll list.

Out of curiosity, victims pick up the bait and insert it into a work or home computer, resulting in the automated installation of malware on the machine.Baiting schemes may not always have to take place in the actual world. Baiting online takes the form of appealing adverts that direct viewers to harmful websites or entice them to download a malware-infected application.

Scareware

Scareware bombards victims with false alerts and phoney threats. Users are duped into believing their system is infected with malware, prompting them to install software that provides no real value (except to the perpetrator) or is malware itself. Scareware is also known as ruse software, rogue scanner software, and fraudware.

A frequent example of scareware is the appearance of legitimate-looking popup advertisements in your browser while surfing the web, with language such as, "Your machine may be infected with nasty spyware applications." It either offers to install the utility (frequently tainted with malware) for you or directs you to a malicious site where your machine becomes infected.

Scareware is also disseminated through spam email, which sends out fake warnings or offers consumers worthless/harmful services.

Pretexting

In this case, an attacker collects information by telling a succession of carefully designed lies. A perpetrator would frequently commence the scam by professing to require sensitive information from a victim in order to complete a key assignment.

The attacker usually begins by gaining trust with their target by impersonating coworkers, police officers, bank and tax authorities, or other individuals with right-to-know authority. The pretexter asks inquiries that are apparently required to validate the victim's identity, allowing them to obtain sensitive personal information.

This fraud collects all kinds of relevant information and records, including social security numbers, personal addresses and phone numbers, phone records, employee vacation dates, bank records, and even security information relating to a physical plant.

Phishing

Phishing scams are email and text message campaigns that try to create a sense of urgency, curiosity, or terror in victims. They are one of the most common types of social engineering attacks. It then manipulates individuals into disclosing personal information, clicking on links to fraudulent websites, or opening attachments containing malware.

An example is an email sent to subscribers of an online service informing them of a policy violation that necessitates prompt action on their side, such as a password change. It contains a link to an illicit website that looks virtually identical to the official version, inviting the unsuspecting user to input their current credentials and a new password. When you submit a form, the information is delivered to the attacker.

Given that phishing campaigns send similar or nearly identical messages to all users, detecting and blocking them is significantly easier for mail servers with access to threat sharing services.

Spear phishing

This is a more targeted variation of the phishing scam in which an attacker selects certain persons or businesses to target. They then customise their communications to their victims' features, employment positions, and contacts in order to make their attack less visible. Spear phishing necessitates far more work on the part of the perpetrator and can take weeks or months to complete.

They are far more difficult to detect and have a higher success rate if done correctly.In a spear phishing scenario, an attacker sends an email to one or more employees while impersonating an organization's IT consultant. It's worded and signed exactly like the consultant usually does, leading recipients to believe it's a legitimate message. The letter instructs recipients to update their passwords and includes a link that takes them to a fraudulent page where the attacker steals their credentials.

Social Engineering Prevention

Social engineers use human emotions like curiosity or terror to carry out schemes and lure victims into their traps. As a result, be cautious if you receive an alarming email, are drawn to an offer shown on a website, or come across loose digital media laying around. Being vigilant can help you protect yourself from the majority of social engineering attempts that occur in the digital arena.

Furthermore, the following pointers can assist you increase your alertness in connection to social engineering hacks.

Don’t open emails and attachments from suspicious sources – You are not required to respond to an email if you do not know the sender. Even if you know them and are sceptical of their message, cross-check and corroborate the information from other sources, such as the telephone or the website of a service provider. Remember that email addresses are constantly spoofing; even an email allegedly from a trusted source could have been launched by an attacker.

Use multifactor authentication– User credentials are one of the most valuable pieces of information that attackers want. Using multifactor authentication helps to protect your account in the case of a system intrusion. Imperva Login Protect is a simple 2-factor authentication solution that helps improve account security for your applications.

Be wary of tempting offers– If an offer sounds too good to be true, think twice before accepting it. You can rapidly evaluate whether you're dealing with a legitimate offer or a trap by Googling the topic.

Keep your antivirus/antimalware software updated – Make sure that automatic updates are turned on, or make it a practise to download the most recent signatures first thing each day. Check to ensure that the updates have been deployed on a regular basis, and scan your system for any infections.
