Exe file - possibly Remcos RAT - and another zip file contains.
Bat file, possibly having script to download and execute Remcos RAT from this IP. This infection contains many stages, and largely depends on the C2 server which stores the required files for each stage.
From an external threat landscape management perspective, the proliferation of numerous IP addresses and infrastructure hosting the Remcos RAT and other malicious files raises significant concerns due to their dynamic role as command and control servers for distributing and downloading malicious payloads.
This report sheds light on the multifaceted, persistent threat posed by the Remcos Remote Access Trojan.
Operating since 2016, Remcos RAT has evolved into a malicious tool employed by threat actors across various campaigns.
Our investigation into the ongoing Remcos RAT hosting on various servers across globe emphasizes its adaptability and evasion tactics.
The discovery of multiple IPs hosting the Remcos RAT underscores the widespread reach of this threat: these IPs serve as conduits for delivering malicious payloads, and the dynamic nature of the infrastructure presents an intricate challenge for mitigation efforts.
Implement robust endpoint security solutions that include advanced threat detection and prevention mechanisms to identify and block malicious activities associated with RATs like Remcos.
Stay updated on the latest threat intelligence reports and indicators of compromise related to Remcos and similar RATs to proactively identify potential threats.
