Rewterz Threat Alert – APT C-35 Targeting Pakistani Organizations

Analysis Summary
The Valak Malware is a sophisticated malware previously classified as a malware loader. Though it was first observed in late 2019, researchers have investigated a series of dramatic changes, an evolution of over 30 different versions in less than six months. This research shows that Valak is more than just a loader for other malware, and can also be used independently as an information stealer to target individuals and enterprises. More recent versions of Valak target Microsoft Exchange servers to steal enterprise mailing information and passwords along with the enterprise certificate. This has the potential to access critical enterprise accounts, causing damage to organizations, brand degradation, and ultimately a loss of consumer trust.
