Executive Summary

The SANS Internet Storm Center report on DOUBLECUP’s latest PNG payload reveals that the malware does not employ genuine steganography. Instead, the malicious code is embedded in the PNG file in a way that bypasses typical steganographic detection, making it appear as a benign image while delivering executable payloads.

Original Description: New malware that uses steganography always gets my attention, but I was disappointed when I looked at the latest DOUBLECUP write-up. It doesn&#;x26;#;39;t use real steganography:
