Cybersecurity researchers from Minerva Labs have noticed a doubtlessly harmful malware (opens in new tab) pressure written in a comparatively new programming language referred to as Nim. 

The crew has warned {that a} rising variety of risk actors are porting their malware to Nim to raised conceal their instruments from antivirus options and cybersecurity groups.

On this case, the Minerva researchers first discovered IceXLoader again in June 2022, when it was thought-about underneath growth, as lots of its core capabilities have been nonetheless lacking. Now, nevertheless, the malware has reached model 3.3.3, comes with fairly a number of harmful options, and has already contaminated “1000’s” of Home windows gadgets – each at dwelling, and within the workplace. 

Cryptominers

When victims obtain and run IceXLoader (which often occurs after a profitable phishing assault), it’ll do plenty of issues – from gathering metadata in regards to the goal endpoint (opens in new tab) (IP deal with, machine identify, OS model, {hardware} info, and many others.), to putting in a cryptocurrency miner for the Monero forex.

Usually talking, IceXLoader is stage-one malware in a multi-stage assault. It would drop extra malware to the goal endpoint, relying on what the risk actors deem most helpful for every particular person machine.

The malware can also be comparatively good at staying hidden. It obfuscates the code, doesn’t run inside Microsoft Defender’s emulator, and executes PowerShell with an encrypted demand, delaying executing the malware for 35 seconds. That manner, it could possibly keep away from sandboxes, as nicely. 

The researchers discovered the malware’s SQLite database file, and found “1000’s of sufferer data”. They’ve begun notifying these folks, it was added.
