New DCOM Attack: Laughing in the Face of Your Windows Security Patches!
Cybersecurity researchers at Deep Instinct have uncovered a new DCOM attack. This stealthy method uses the Windows Installer service to deploy backdoors, remotely writing and executing malicious DLLs. Fortunately, consistent DCOM hardening patches can reduce the attack’s effectiveness, but only if your IT team isn’t practicing their stealthy avoidance techniques.
Hot Take:
Who knew DCOM could be so DCOMplicated? Just when you thought your Windows Installer was only good for endless updates and pop-up annoyances, it turns out it’s also a secret agent for cyber mischief. Maybe it’s time to say goodbye to our old friend DCOM and hello to something a little less treacherous!
Key Points:
- DCOM attack uses Windows Installer for sneaky backdoor setups.
- Exploits IMsiServer interface for remote code execution.
- Malicious DLLs are remotely executed, compromising systems.
- Attack needs attacker and victim in the same domain, limiting its reach.
- Patching DCOM can reduce the attack’s effectiveness.
