Multiple rundll32.exe processes spawned from child PowerShell with null command lines

rundll32.exe process injection chain

Analyst narrative

Six rundll32.exe processes (PIDs 2216, 5452, 4108, 6768, 5588, 8148) were spawned from PowerShell (PID 5848) with null command lines. This injection pattern is consistent with process hollowing or DLL injection attacks.
