A new piece of malware dubbed dotRunpeX is being used to distribute numerous known malware families such as Agent Tesla, Ave Maria, BitRAT, FormBook, LokiBot, NetWire, Raccoon Stealer, RedLine Stealer, Remcos, Rhadamanthys, and Vidar.

"DotRunpeX is a new injector written in.NET using the Process Hollowing technique and used to infect systems with a variety of known malware families," Check Point said in a report published last week.

Said to be in active development, dotRunpeX arrives as a second-stage malware in the infection chain, often deployed via a downloader that's transmitted through phishing emails as malicious attachments.

The latest DotRunpeX artifacts, first spotted in October 2022, add an extra obfuscation layer by using the KoiVM virtualizing protector.

Check Point's analysis has further revealed that "Each dotRunpeX sample has an embedded payload of a certain malware family to be injected," with the injector specifying a list of anti-malware processes to be terminated.

The most frequently delivered malware families delivered by the emerging threat include RedLine, Raccoon, Vidar, Agent Tesla, and FormBook.
