An investigation into the cyberattack targeting Iranian national media corporation, Islamic Republic of Iran Broadcasting, in late January 2022 resulted in the deployment of a wiper malware and other custom implants, as the country's national infrastructure continues to face a wave of attacks aimed at inflicting serious damage. The 10-second attack, which took place on January 27, involved the breach of state broadcaster IRIB to air pictures of Mujahedin-e-Khalq Organization leaders Maryam and Massoud Rajavi alongside a call for the assassination of the Supreme Leader Ayatollah Ali Khamenei.

Footage of opposition leaders calling for the assassination of Iran's Supreme Leader ran on several of the nation's state-run TV channels in late January after a state-sponsored cyber-attack on Iranian state broadcaster IRIB. The incident - one of a series of politically motivated attacks in Iran that have occurred in the last year - included the use of a wiper that potentially ties it to a previous high-profile attack on Iran's national transportation networks in July, according to researchers from Check Point Research. Though the earlier attacks have been attributed to Iran state-sponsored actor Indra, researchers believe a copycat actor was behind the IRIB attack based on the malware and tools used in the attack, they said in a report published Friday.
