In the last few weeks of July 2022, researchers reported two attacks where Steganography was used to deliver malware payloads. In the first event, TAs compromised Alibaba OSS Buckets to Distribute Malicious Shell Scripts via Steganography. In the other event, KNOTWEED malware used the JPEG file to hide Corelump malware. Interestingly, the same technique was used in both incidents to hide the malware payload inside image files. The malicious code was appended after the image content, which ensured that the victim could only access the image without seeing the malicious code. However, accessing stegomalware will not execute any embedded content. Rather, it will be accessed and executed by other programs.
