“The lousy actor works by using a .DMG file to unfold the malware. Immediately after a person executes the file, it opens a bogus password prompt to acquire passwords,” Trivedi stated.
The stealer was then noticed creating ZIP archives of the stolen details and sending it to its command and manage (C2) infrastructure through a Submit ask for working with a Python user-agent command. It concludes its attack chain by deleting the facts and ZIP file from the victim’s procedure.
“Simultaneously, the MacStealer transmits chosen data to the outlined Telegram channels,” Trivedi reported. “Once it has sent the compiled ZIP file to the C2, the latter shares the file with a risk actor’s particular Telegram bot.”
Seeking at the VirusTotal graph for MacStealer, the Uptycs crew noticed many different malware samples. The danger actor involving the infostealer also seemed to be actively performing on updating it with new features, which include cryptocurrency theft, reverse shell and much more.
“We observed the distributor has a mass generation order for MacStealer from other risk actors, thus, the malware is probable to be distribute far more widely,” Trivedi warned.
To guard from this menace, the security researchers encouraged people keep their Mac devices up-to-date and permit only file set up from trustworthy sources permitted by the “Allow apps downloaded from Application Retailer/Application Store and determined developers” placing.
