Previously targeting academics, diplomats, and journalists among others, TA453 has expanded to target medical researchers, aerospace engineers, realtors, and travel agencies. New tactics include the use of compromised accounts, malware, and confrontational lures.

About Affiliation
TA453
TA453 is Proofpoint's designation for the Iranian state-sponsored threat actor widely known as APT42, linked to Iran's Islamic Revolutionary Guard Corps Intelligence Organization (IRGC-IO). Active since at least 2014, TA453 is known for highly targeted spear phishing campaigns using elaborate social engineering — including multi-persona impersonation and fake conference invitations — to harvest credentials from journalists, academics, human rights activists, and policy experts. Proofpoint has documented the group's use of malware families such as HYPERSCRAPE and novel infection chains targeting both Windows and macOS platforms.
