Transparent Tribe APT expands its Windows malware arsenal

Summary: Transparent Tribe, also tracked as APT36 and Mythic Leopard, is expanding its Windows malware arsenal beyond CrimsonRAT to include ObliqueRAT, delivered through fake domains that mimic Indian defense and government sites and through domains posing as file-sharing services. Cisco Talos found the group registered clawsindia[.]com to impersonate the Center For Land Warfare Studies think tank, hosted on 164[.]68[.]101[.]194, a known CrimsonRAT command-and-control IP, with a mail[.]clawsindia[.]com subdomain suggesting a malspam campaign. Its targeting has widened from military and defense personnel to diplomatic entities, defense contractors, research organizations, and conference attendees.

Why it matters: The group's TTPs have stayed largely unchanged since 2020, yet it keeps adding lures and a second implant, so defenses tuned to CrimsonRAT alone may not catch ObliqueRAT arriving from a cloned think-tank domain or a lookalike file-sharing site.
