The threat actor tracked as TA558 has been observed leveraging steganography as an obfuscation technique to deliver a wide range of malware such as Agent Tesla, FormBook, Remcos RAT, LokiBot, GuLoader, Snake Keylogger, and XWorm, among others.
"The group made extensive use of steganography by sending VBSs, PowerShell code, as well as RTF documents with an embedded exploit, inside images and text files," Russian cybersecurity company Positive Technologies said in a Monday report.
The campaign has been code named SteganoAmor for its reliance on steganography and the choice of file names such as greatloverstory.vbs and easytolove.vbs.
