Iranian Hackers Behind Cox Media Group Ransomware Attack

 

Iranian hackers were behind the ransomware attack that disrupted Cox radio and TV stations' IT systems and live streaming earlier this year, according to The Record. 

The attack was carried out by a threat actor known as DEV-0270, which has been linked to many incursions against US organizations this year that resulted in the deployment of ransomware. While the Cox Media Group's infiltration was discovered on June 3 when the attackers used ransomware to encrypt some internal servers, the group had been breaching and hiding inside the company's internal network since mid-May. 

The attack did not affect all Cox Media Group radio and television stations, but it did disrupt certain stations' capability to broadcast live feeds on their websites. Initially, the Cox Media Group attempted to downplay the incident. 

Local reporters who used Twitter to convey information about the ransomware attack were admonished and forced to withdraw their posts. However, four months later, in October, the corporation finally confirmed the incident, although without disclosing any details about the Iranian hackers. 

The disclosure that Iranian hackers were behind the Cox attack comes less than a month after the US Department of Justice charged two Iranian citizens with various hacking-related offenses in November. One of them was for compromising a US media firm with the goal of disseminating false information about the legality of the US 2020 Presidential election via its website. 

Lee Enterprises, which owns the Buffalo News, the Arizona Daily Star, and the Omaha World-Herald, was eventually confirmed as the company. DEV-0270 has previously engaged in both information-collection operations and financially motivated attacks, according to a Microsoft threat intelligence analysis on the group, obscuring the true reason behind the recent Cox ransomware attack. 

The strategy of delivering ransomware on the networks of large corporations was first detected in late 2016 by Iranian hackers, namely the SamSam group. Their strategy of focusing on large businesses rather than end-users was later adopted by the majority of ransomware threat actors, and is now known as "big-game hunting." 

Since then, the majority of ransomware attacks have been attributed to Russian-based groups; however, certain ransomware cases have also been linked to members of state-sponsored espionage groups operating in Iran, China, and North Korea in recent years. 

These groups used ransomware on the networks of some of their victims as a path to monetize compromised companies with no intelligence-collection value or to hide intelligence collection behind a more generic ransomware issue that wouldn't prompt a more in-depth examination. 

Cox Media Group spokespersons did not respond to inquiries for comment on the incursion in May and June.
