Researchers from Symantec’s Threat Hunter Team detected an espionage group using steganography to further their activities. The Witchetty espionage group exploited five ProxyShell and ProxyLogon vulnerabilities to install web shells, then stole access credentials and began moving laterally through compromised networks. The steganographic portion of the attack hides malicious code in a Windows logo graphic. The steganographic bitmap image is deployed with the help of a backdoor Trojan.

Note

  • This looks like yet another example where the attacker attached an obfuscated executable to an image (which isn’t steganography in my opinion), and used a common cloud service to deliver the image. Lazy detection systems often ignore content past the initial header and this trick isn’t new but effective. Catchy headline, but nothing really new.
  • Steganography is very interesting and capturing the source image is tempting. Use care handling it if you go down that path. This attack is new functionality added to the LookBack back door and the image (the jacked up windows logo) is stored on a GitHub repository. The Symantec blog has IOCs for you to incorporate. The attack is leveraging weaknesses in public facing services, e.g., exchange. The best mitigation is to actively update any public facing services and regularly verify they are running current security configurations.
