PowerShell Shenanigans: When Malicious Code Goes Undercover!
PowerShell strikes again! Attackers are using it to bypass EDRs, loading shellcode like it’s just another day at the office. With VirtualAlloc and CallWindowProc, they avoid new threads, keeping things stealthy. But don’t worry, sometimes their plans crash harder than a Windows 98 screensaver. Stay vigilant, folks!
Hot Take:
When shellcodes and PowerShell scripts combine forces, it’s like watching a villainous duo plot world domination. While EDRs are busy playing shellcode whack-a-mole, attackers are slipping through the cracks like cyber ninjas, using techniques you’d expect from a spy movie script. Who knew a simple PowerShell command could pack such a punch? It’s like a bad guy using a Swiss Army knife to hack the Pentagon.
Key Points:
– Attackers are using PowerShell scripts to bypass traditional shellcode execution defenses.
– The script allocates executable memory using VirtualAlloc and VirtualProtect.
– Obfuscated shellcode is copied and executed using the IEX command.
– CallWindowProcA is being used to execute shellcode without creating new threads.
– This technique resembles standard GUI behavior, making it hard to detect.
