Rewterz Threat Alert – AveMaria RAT aka WarzoneRAT – Active IOCs

Severity

High

Analysis Summary

AveMaria RAT – aka WarzoneRAT – is a remote access trojan that targets Windows systems that provides the capability to gain unauthorized access to a victim’s PC or allow covert surveillance of it. It acts as a keylogger, can steal passwords, escalate privileges, and much more. AveMaria, like most malware, first arrives at systems as a result of phishing emails (as invoices and shipping orders), but is also available on the dark web for subscriptions. This malware-as-a-service RAT is written in C++ that has been available for purchase since at least 2018. Once the RAT has infected a system, it establishes a backdoor that allows the attacker to control the system from a remote location.

To protect against AveMaria RAT and other malware, it is essential to keep your software up to date, use strong passwords, avoid suspicious links and attachments, and install reputable antivirus software.

Remediation

• Block all threat indicators at your respective controls.
• Search for Indicators of compromise (IOCs) in your environment utilizing your respective security controls
• Maintain cyber hygiene by updating your anti-virus software and implementing a patch management lifecycle.
• Maintain Offline Backups – In a ransomware attack, the adversary will often delete or encrypt backups if they have access to them. That’s why it’s important to keep offline (preferably off-site), encrypted backups of data and test them regularly.
• Emails from unknown senders should always be treated with caution.
• Never trust or open ” links and attachments received from unknown sources/senders.
• Patch and upgrade any platforms and software timely and make it into a standard security policy. Prioritize patching known exploited vulnerabilities and zero-days.
• Along with network and system hardening, code hardening should be implemented within the organization so that their websites and software are secure. Use testing tools to detect any vulnerabilities in the deployed codes.
• Enable antivirus and anti-malware software and update signature definitions in a timely manner. Using multi-layered protection is necessary to secure vulnerable assets
