Clever Chinese Hackers: AppDomain Manager Injection and GrimResource Attacks Strike Again!
AppDomain Manager Injection, a sneaky .NET trick from 2017, is causing havoc in 2024. Attackers, possibly APT 41, are targeting Taiwan, the Philippines, and Vietnam. This stealthy technique makes malicious code look legit, slipping past defenses like a ninja at a dinner party.
Hot Take:
“Why hack the planet when you can hijack a .NET AppDomain?!” These attackers are like master chefs, whipping up a malware souffle with ingredients no one was watching.”
Key Points:
- AppDomain Manager Injection is a stealthy .NET Framework hack technique.
- Recent attacks target government, military, and energy sectors in Taiwan, the Philippines, and Vietnam.
- GrimResource exploits XSS vulnerabilities to run .NET code via Microsoft Management Console (MMC).
- NTT suggests a possible, but not confirmed, link to Chinese APT41.
- The attacks ultimately deploy a CobaltStrike beacon for further malicious actions.
