A nascent Go-based malware often called Aurora Stealer is being more and more deployed as a part of campaigns designed to steal delicate info from compromised hosts.
“These an infection chains leveraged phishing pages impersonating obtain pages of reliable software program, together with cryptocurrency wallets or distant entry instruments, and the 911 methodology making use of YouTube movies and Search engine marketing-poised pretend cracked software program obtain web sites,” cybersecurity agency SEKOIA stated.
First marketed on Russian cybercrime boards in April 2022, Aurora was provided as a commodity malware for different risk actors, describing it as a “multi-purpose botnet with stealing, downloading and distant entry capabilities.”
In the intervening months, the malware has been scaled all the way down to a stealer that may harvest recordsdata of curiosity, knowledge from 40 cryptocurrency wallets, and purposes like Telegram.
