The researchers won a minimum of 800 effects for RedLine variants detected as ‘engines:MSIL.Trojan-Stealer.Redline.B.’ They looked for the ‘DomainDetects.txt’ document used to add information, and located effects tagged ‘content material:DomainDetects.txt tag:zip’.

The use of VirusTotal gear, they came upon that the zipped document contained every other RAR document (TG @BitPapaFREELOGS 08.2021 500 PIECES.rar) with 22,715 passwords from 500 sufferers.

BitPapa is the title of a Russian cryptocurrency marketplace and in addition a telegram channel. The researchers advised that the recordsdata had been intentionally uploaded to VirusTotal.

Moreover, the researchers came upon recordsdata presented on DrDark and Snatch_Cloud underground boards thru VirusTotal seek.

“Those actions are performed at the common internet,” they wrote. “There’s no want for darkish internet get admission to—those people don’t seem to be hiding themselves.”

The researchers submitted their analysis findings, recordsdata containing private information, and the implicated API keys to Google. The beneficial periodically looking and doing away with delicate information from VirusTotal and banning API tokens used to add stolen consumer credentials.
