Authorities Turn Sality's P2P Network Against Itself, Cutting Off New Malware Payloads

US and European authorities with CrowdStrike dismantled the two-decade-old Sality P2P botnet using peer-list manipulation, blocking payload delivery to infected hosts.

The US Department of Justice announced a coordinated takedown of the Sality peer-to-peer botnet, executed August 31, 2026 by authorities from the US, Bulgaria, Hungary, and Romania with CrowdStrike and the Shadowserver Foundation. Sality, active since 2003, infects Windows executables and delivers payloads including the EggJagger crypto clipper, which stole at least $150,000, and was used for DDoS campaigns. The operation abused the botnet's peer-list maintenance cycle to insert sinkhole nodes and isolate both super peers and NAT-hidden infections, cutting off URL and payload distribution to more than 15,000 infected machines across two P2P networks.

Upatre Continued to Evolve with new Anti

Unit 42 analyzes an undocumented Upatre downloader variant with VM detection via process hashing, packed code, disabled Windows defenses and Namecoin .bit C2 domains.

Unit 42 analyzed an Upatre downloader variant compiled in December 2016 that went largely undetected by automated systems, featuring heavy code flow obscuration, on-demand decryption of network communications, and novel virtual machine detection. The sample enumerates running processes, computes CRC32 hashes XORed with a hard-coded key, and sleeps if analysis-related processes such as vmtoolsd.exe or python.exe are found. It masquerades with Google Chrome icons, disables Windows Defender, Firewall and other security services, injects code into msiexec.exe, and resolves .bit Namecoin domains like bookreader[.]bit via hardcoded OpenNIC DNS servers over TCP.
