Protecting Your Cloud Infrastructure: The Threat of TeamTNT and Cryptojacking
Cloud computing is still transforming how businesses function, it also creates new weaknesses that bad actors might take advantage of. The hacker group TeamTNT has recently launched a number of attacks that target cloud infrastructure in particular, which has cybersecurity experts extremely concerned. The main goal of these assaults is to mine Bitcoin via a method called cryptojacking, which entails taking control of other systems’ computer resources without the owners’ knowledge or permission.
In order to seize control and take use of resources for clandestine mining activities, TeamTNT deliberately targets weak cloud systems, particularly those that are running Docker containers. This concerning trend emphasizes how crucial cloud computing is to protecting digital assets and infrastructure.
Understanding the history of TeamTNT, the idea of cryptomining, and the full effects of these assaults requires
Who Is TeamTNT? The Hacker Group Targeting Cloud Servers
A cybercriminal organization called TeamTNT has been disrupting businesses by targeting their cloud infrastructure. TeamTNT, which started operating around 2020, is notorious for taking advantage of security flaws in cloud computing services like Docker and Kubernetes. They look for systems with inadequate security configurations, which makes it easier for attackers to infiltrate and seize control. Additionally, TeamTNT is renowned for automating their attacks, which facilitates their rapid and easy hacking of several cloud computing services.
TeamTNT’s most recent attack takes a different approach to their search for cloud setup vulnerabilities. According to reports, they have begun renting out these hacked servers to other people rather than just utilizing them to mine cryptocurrencies for themselves. This enables them to generate revenue without having to operate the servers directly. As a result, the group can now profit more efficiently, while the compromised servers may be used for a variety of cybercrimes.
Crypto Mining Explained: What It Is and Why Hackers Target Cloud Servers for It
What Is Crypto Mining?
Verifying and adding new digital transactions to the blockchain—the technology that underpins cryptocurrencies—is known as cryptomining, or cryptocurrency mining. Miners keep the network safe and operational by using powerful computers to solve challenging mathematical challenges. Miners are compensated with tiny quantities of money, such as Bitcoin or Monero. Although effective cryptomining may provide significant profits, it often demands costly equipment and a lot of power.
What Is Cryptojacking?
The illicit version of cryptomining is called cryptojacking. Hackers like TeamTNT engage in cryptojacking when they mine bitcoin on another person’s computer or cloud computing server without that person’s consent. These hackers infiltrate other systems and utilize their resources for mining rather than purchasing their own equipment or paying for energy. While the hackers benefit, the victim’s systems get slower due to the depletion of their resources caused by cryptojacking.
TeamTNT’s Attack Strategy: How They Target Cloud Servers
This is how TeamTNT normally functions:
- Finding Open services: TeamTNT employs techniques to find cloud computing services with inadequate security by scanning a huge number of them. They specifically target Docker, a well-liked application deployment technology. If not adequately protected, Docker can be susceptible, which makes it a popular target for hackers.
- Deploying Malicious Containers: TeamTNT uses their own malicious container, which is essentially a mini-program, to take control of the server’s resources after identifying a system that is susceptible. This container executes a script that enables remote system control via TeamTNT.
- Using Docker Hub to Distribute virus: TeamTNT uses Docker Hub, a platform for application sharing, to conceal their virus. Before their actions are noticed, they may swiftly infect several devices by disseminating malware via Docker Hub.
- Using the Sliver Framework for Control: TeamTNT recently shifted from using outdated backdoor programs to using a tool known as Sliver. They may conduct cryptomining operations on compromised systems without the victim recognizing thanks to Sliver, which makes it difficult to identify them.
- Renting Out Hacked Servers: TeamTNT has discovered a new source of revenue after seizing control of a server: charging other criminals to use these compromised servers. They use websites such as Mining Rig Rentals to achieve this, allowing others to utilize the resources for bitcoin mining without.
How Cloud Security Can Prevent Cryptojacking
What Is Cloud Computing?
Instead of storing everything on local computers or in actual data centers, cloud computing allows users to access computing power, storage, and other resources over the internet. Businesses can run apps, manage and store data, and more using cloud computing providers like Microsoft Azure, Google Cloud, and Amazon Web Services. Although the cloud computing provides cost savings and flexibility, it also need robust security procedures to fend against intrusions.
Key Cloud Security Practices to Prevent Cryptojacking
Here are some crucial steps to protect your systems if you use cloud computing services:
- Establish Appropriate Security Configurations: Verify that robust security settings are in place for all cloud computing services and resources. Docker instances are left vulnerable, which makes many of TeamTNT’s assaults successful. Firewalls and access controls are examples of basic security setups that can have a significant impact.
- Keep an Eye Out for Strange Activity: Cryptojacking may be identified with the use of monitoring tools that keep tabs on system activity and performance. Investigating sudden increases in CPU utilization or network activity is crucial since these indicators might indicate an assault.
- Update Systems and Software Frequently: Cloud providers update their systems frequently, but in order to avoid security flaws, users must also keep their apps updated. This procedure can be streamlined with automated patching technologies, which lower the the risk of vulnerabilities being exploited.
- Provide your staff with training on cloud security best practices. Simple errors, such as failing to protect an API endpoint, are the cause of many assaults. These kinds of mistakes can be avoided and total risk can be decreased with proper training.
- Employ Secure DNS Services: To cover their footprints, TeamTNT use a method known as anonymized DNS. Cloud providers’ secure DNS systems can give an additional degree of security, making it more difficult for hackers to employ this strategy.
- Layered protection Measures: By putting in place many levels of protection, including encryption, intrusion detection systems, and stringent access rules, hackers may find it more difficult to enter and remain hidden. This multi-layered strategy aids in defending against both first assaults and persistent dangers.
Final Thoughts: The Role of Cloud Security in Combating TeamTNT’s Attacks
The recent hacks by TeamTNT serve as a reminder of how important cloud system security is. Although the cloud has revolutionized business operations, it also poses new concerns. Businesses may protect themselves from dangers like cryptojacking by being vigilant and adhering to security best practices.
With new tools and techniques created to identify and counteract complex assaults like TeamTNT’s, cloud security will continue to advance. However, businesses can get started right now by strengthening cloud security, keeping an eye out for odd activity, and educating their staff. By taking these precautions, businesses may profit from the cloud without sacrificing security.
