Researchers smell a cryptomining Chaos RAT targeting Linux systems
A type of cryptomining malware targeting Linux-based systems has added capabilities by incorporating an open source remote access trojan called Chaos RAT with several advanced functions that bad guys can use to control remote operating systems.
Trend Micro security researchers discovered the threat last month. Like earlier, similar versions of the miner that also target Linux operating systems, the code killsThe newer malware then establishes persistence"by alteringAfter that, it downloads an XMRig miner, a configuration file, another payload that continually kills competing malware, and the Chaos RAT , which is written in Go and has a ton of capabilities including restarting and shutting down the victim's machine.
Additionally, the open source tool can perform reverse shell on the infected system, take screenshots of the victim's device, collect info on the operating system, and download, upload or even delete files. "An interesting trait of the malware family we intercepted is that the address and access token are passed as compilation flags and hardcoded inside the RAT client, replacing any data inside variables from the main code," the researchers wrote.
They also noted that the main server, used for downloading payloads, appears to be in Russia, while the Chaos RAT connects to another command-and-control server believed to be in Hong Kong.
