🎯 Content Summary

Unit 42 analyzes CL-STA-1062, a Chinese-speaking activity cluster active since at least March 2022 and assessed with high confidence to overlap with Cisco Talos UAT-7237.

From that web shell, operators can run arbitrary commands, drop tunneling and credential tools, perform system and network reconnaissance, stage source-code directories, access databases such as MSSQL, and exfiltrate results. The reusable defensive lesson is to treat any web shell as full host compromise and hunt for suspicious child processes of web server workers, command interpreters, archive tools, curl, tunneling binaries, and database clients.

AppDomainManager Injection with adjacent .NET config files: a legitimate signed .NET executable can be abused if an attacker can place a malicious adjacent .exe.config file and a malicious AppDomain manager DLL next to it. When the executable starts, the .NET runtime reads the ...
