The Witchetty espionage group (aka LookingFrog) has been progressively updating its toolset, using new malware in attacks on targets in the Middle East and Africa. Among the new tools being used by the group is a backdoor Trojan (Backdoor.Stegmap) that employs steganography, a rarely seen technique where malicious code is hidden within an image.

The attackers exploited the ProxyShell (CVE-2021-34473, CVE-2021-34523, and CVE-2021-31207) and ProxyLogon (CVE-2021-26855 and CVE-2021-27065) vulnerabilities to install web shells on public-facing servers before stealing credentials, moving laterally across networks, and installing malware on other computers.
