The Russian state-sponsored hacking group known as
Turla
has transformed its custom backdoor Kazuar into a modular peer-to-peer (P2P) botnet that's engineered for stealth and persistent access to compromised hosts.
Turla, per the U.S. Cybersecurity and Infrastructure Security Agency (CISA), is assessed to be affiliated with Center 16 of Russia's Federal Security Service (FSB). It overlaps with activity traced by the broader cybersecurity community under the names ATG26, Blue Python, Iron Hunter, Pensive Ursa, Secret Blizzard (formerly Krypton), Snake, SUMMIT, Uroburos, Venomous Bear, Waterbug, and WRAITH.
