Pioneer Kitten is a hacker group that specializes in infiltrating corporate networks using open-source tools to compromise remote external services. Researchers observed an actor associated with the group advertising access to compromised networks on an underground forum in July. The credentials would let other cybercriminal groups and APTs perform cyberespionage and other nefarious cyber-activity. The group does not appear to be directly operated by the Iranian government but is sympathetic to the regime and likely a private contractor, an analyst says. Iran has emerged in recent years as a formidable cyber-enemy, amassing a number of APTs to mount attacks on political adversaries.
