What it detects

This rule detects the WMI provider host WmiPrvSE.exe spawning ImagingDevices.exe, Wab.exe, or Wabmig.exe, the seldom-executed signed Windows binaries that Ramnit uses as injection hosts after sLoad delivery in the drIBAN banking-fraud operation. Adversaries launch these low-noise processes from WMI to host injected banking-trojan code under a trusted image, making early detection critical for surfacing the intrusion before man-in-the-browser fraud.
