The Rise Of GRAMDOOR And STARWHALE In The Middle East: UNC3313 Suspected

The Iranian cyber espionage group UNC3313, also known as TEMP.Zagros and MuddyWater, has been identified as the perpetrator of a series of cyber attacks on Middle Eastern government and technology entities. The group used new targeted malware, GRAMDOOR and STARWHALE, to exploit vulnerabilities and gain unauthorized access. UNC3313 also utilized publicly available remote access software and modified open-source offensive security tools for lateral movement within the targeted systems. The group's activities suggest a strong focus on geopolitical targets and the telecommunications sector in the Middle East. The use of the Telegram API for command and control allows for malicious traffic to blend in with legitimate user behavior, indicating the group's efforts to evade detection.
