The Brief
- The South Asia-focused cyberespionage group Bitter (also tracked as APT-C-08, APT-Q-37, Hazy Tiger, Orange Yali, T-APT-17 and TA397) is targeting South Asian organizations.
- The campaign uses a previously unreported remote access trojan called PapRAT.
- PapRAT is reported to be written in both C++ and Rust.
Why it matters
Organizations in South Asia, and their developers and IT staff, face a newly documented remote access trojan used for espionage, so detection and hardening matter.
