Dell SecureWorks said a new version of the Stegoloader malware uses steganography to hide itself from detection. Steganography is used to hide information inside another message or image. Dell researchers said they have not seen the malware used in targeted attacks, but they don t dismiss the possibility outright. So far, Dell said it has seen victims in the health care, education, and manufacturing industries, yet it has not been spread via exploits or spearphishing emails.
