New dotRunpeX Malware Spreads via Malicious Ads

Attacks, Malware

According to Check Point’s study, “each dotRunpeX sample has an embedded payload of a certain malware family to be injected,” with the injector identifying a list of anti-malware processes that should be terminated. This is made possible by exploiting a weak process explorer driver (procexp.sys) built into dotRunpeX to gain kernel mode execution. The malware may be linked to Russian-speaking threat actors.
