Iranian Infy Prince of Persia Cyber Espionage Campaign Resurfaces

Security researchers have identified renewed cyber activity linked to an Iranian threat actor known as Infy, also referred to as Prince of Persia, marking the group’s re-emergence nearly five years after its last widely reported operations in Europe and the Middle East. According to SafeBreach, the scale and persistence of the group’s recent campaigns suggest it remains an active and capable advanced persistent threat. 

Infy is considered one of the longest-operating APT groups, with its origins traced back to at least 2004. Despite this longevity, it has largely avoided the spotlight compared with other Iranian-linked groups such as Charming Kitten or MuddyWater. Earlier research attributed Infy’s attacks to a relatively focused toolkit built around two primary malware families: Foudre, a downloader and reconnaissance tool, and Tonnerre, a secondary implant used for deeper system compromise and data exfiltration. These tools are believed to be distributed primarily through phishing campaigns. 

Recent analysis from SafeBreach reveals a previously undocumented campaign targeting organizations and individuals across multiple regions, including Iran, Iraq, Turkey, India, Canada, and parts of Europe. The operation relies on updated versions of both Foudre and Tonnerre, with the most recent Tonnerre variant observed in September 2025. Researchers noted changes in initial infection methods, with attackers shifting away from traditional malicious macros toward embedding executables directly within Microsoft Exce
