Threat details

OopsIE is delivered via spear phishing email containing a direct link, with OilRig performing extensive social engineering and reconnaissance beforehand.

Once installed, the trojan creates a VBScript file to maintain persistence and run itself every three minutes if it is not already active. It then initiates communication with its command and control (C2) infrastructure using the the InternetExplorer application object over HTTP. This results in the C2 traffic appearing legitimate.

The purpose of OopsIE appears to be to collect information on the system and user, however it is also able to execute commands and transfer files.

Remediation advice
