"Global Organizations Targeted by New SteganoAmor Steganography Attacks"

The TA558 hacking group has launched a new campaign called "SteganoAmor," utilizing steganography to conceal malicious code inside images and target over 320 organizations globally. The attacks begin with emails containing document attachments that exploit a Microsoft Office vulnerability, leading to the download of various malware tools. The group's use of steganography makes detection challenging, and the attacks have affected multiple sectors and countries. Updating Microsoft Office to a more recent version can effectively defend against these attacks, and a list of indicators of compromise (IoCs) is available for reference.
