Security News > 2024 > April > New SteganoAmor attacks use steganography to target 320 orgs globally
A new campaign conducted by the TA558 hacking group is concealing malicious code inside images using steganography to deliver various malware tools onto targeted systems.
The researchers identified over 320 attacks in this campaign that affected various sectors and countries.
The attacks begin with malicious emails containing seemingly innocuous document attachments that exploit the CVE-2017-11882 flaw, a commonly targeted Microsoft Office Equation Editor vulnerability fixed in 2017.
Using a seven-year bug in TA558's attack chain makes it fairly easy to defend against SteganoAmor, as updating Microsoft Office to a more recent version would render these attacks ineffective.
