The Russia-linked hacking crew known as Turla has been observed using an updated version of a known second-stage backdoor referred to as Kazuar.

The new findings come from Palo Alto Networks Unit 42, which is tracking the adversary under its constellation-themed moniker Pensive Ursa.

"As the code of the upgraded revision of Kazuar reveals, the authors put special emphasis on Kazuar's ability to operate in stealth, evade detection and thwart analysis efforts," security researchers Daniel Frank and Tom Fakterman said in a technical report. "They do so using a variety of advanced anti-analysis techniques and by protecting the malware code with effective encryption and obfuscation practices."
