May 26, SecurityWeek – (International) “Wekby” group uses DNS requests for C&C communications. Security researchers from Palo Alto Networks discovered that an advanced persistent threat (APT) group named Wekby, APT 18, Dynamite Panda, and TG-0416, was using the “pisloader” malware to infiltrate a system via Domain Name System (DNS) requests for command & control (C&C) communications, which allows the malware to bypass security products. The “pisloader” malware was believed to be a variant of the HTTPBrowser, a remote access trojan (RAT). Source
