Category: Malware

Type: Trojan, remote access trojan, backdoor, fileless malware

Platform: Primarily Windows

Damage potential: Data theft, deployment of additional payloads (such as  ransomware), remote control and surveillance

Overview

BitRAT is a remote access trojan (RAT) that has been sold on underground cybercriminal web markets and forums since at least 2021. It costs as little as $20 for lifetime access and requires minimal technical expertise, making it a popular choice for cybercriminals seeking a cost-effective yet powerful RAT.

BitRAT allows attackers to take full control of infected machines, steal sensitive information through features like webcam access and keylogging, and execute arbitrary commands, like cryptocurrency mining or DDoS attacks. What makes BitRAT especially dangerous is its persistence mechanisms, which can make it difficult to detect and remove. It often operates within legitimate system processes to evade detection. 

Possible symptoms

BitRAT tries to avoid detection, but you may notice some unusual symptoms, such as slower system performance. If your device becomes slower than usual or crashes frequently, running a system scan is a good idea.

Other signs to watch out for:

  • A higher CPU usage.
  • Unauthorized access (like random mouse movements or the webcam activating without you doing so).
  • Unexpected pop-ups or system errors.
  • Added or modified files or lower storage space.
  • New or unknown processes running in the Task Manager.

Sources of the infection

BitRAT may infiltrate the device through:

  • Malicious email attachments or links leading to infected downloads.
  • Cracked software, like unofficial Microsoft Windows activators.
  • Malicious websites or ads.
  • Infected USB drives, external hard drives, or other removable media.
  • Exploitation of vulnerabilities in software or systems.

Protection 

The best way to protect yourself from BitRAT, or any malware for that matter, is to use common sense and stay alert for anything suspicious online. Follow general cybersecurity practices to stay one step ahead of the cyber threats:

  • Do not click on suspicious links or attachments in emails, especially if they come from unknown senders.
  • Keep your software updated to ensure you have the latest security patches.
  • Download software only from official sources, like the app store or developer’s website.
  • Use a firewall to monitor and control incoming and outgoing network traffic.
  • Use security software like NordVPN’s Threat Protection Pro™ to block malicious websites and harmful ads.

BitRAT removal 

BitRAT is designed to avoid detection, so removing this trojan may be challenging. While your best bet would be to perform a complete system wipe, you can also use antivirus software to remove BitRAT from your Windows device:

  • Disconnect the infected computer from the network to stop the malware from spreading further.
  • Boot Windows into safe mode to limit the malware’s ability to run.
  • Perform a full system scan with trusted and updated antivirus software.
  • Manually inspect running processes in the Task Manager for any unfamiliar or suspicious activity and end them.
  • Restart your computer and run another full scan to make sure no traces are left.
  • After removal, change all your passwords because they may have been compromised.
