Analysis Summary
Remcos malware has been operating since 2016. This RAT was originally promoted as genuine software for remote control of Microsoft Windows from XP onwards and is frequently found in phishing attempts due to its capacity to completely infect an afflicted machine. Remcos malware attacks Windows systems and provides the attacker complete control over the machine. It is frequently distributed by malicious documents or archive files that contain scripts or executables. Remcos, like other RATs, offers the threat actor complete access to the infected PCs which allows them to record keystrokes, passwords, and other critical information. Remcos RAT is designed to maintain persistence on the infected system, ensuring that it remains active even after the system reboots. Remcos incorporates various obfuscation and anti-debugging techniques to evade detection. The primary purpose of Remcos RAT is to facilitate data theft and espionage. Attackers can use it to steal sensitive information like login credentials, financial data, personal documents, and other confidential files.
To protect against such threats, always ensure your systems have up-to-date antivirus software, use strong and unique passwords, be cautious when opening email attachments or clicking on suspicious links, and keep your software and operating systems patched and updated.
