Executive Summary
In February 2023, Dish Network, a prominent U.S. satellite television provider, fell victim to a significant ransomware attack orchestrated by the Black Basta group. This attack compromised the personal information of nearly 300,000 individuals, primarily affecting employee-related records. The incident led to widespread service outages, impacting Dish's internal communications, customer call centers, and websites. The attack underscores the critical importance of robust cybersecurity measures and the need for organizations to be prepared for sophisticated ransomware threats.
Technical Information
The Dish Network ransomware attack began on February 23, 2023, and was attributed to the Black Basta ransomware gang, notorious for its double-extortion tactics. This method involves exfiltrating data and demanding a ransom to prevent its publication. The breach primarily impacted employee-related records, including sensitive personal information such as driver's license numbers. Fortunately, customer databases were reportedly not accessed during the attack.
The Black Basta group has been linked to other high-profile ransomware incidents, including an attack on British outsourcing giant Capita. Their tactics, techniques, and procedures (TTPs) align with the MITRE ATT&CK framework, particularly in the areas of data exfiltration and ransom demands. The attack on Dish Network resulted in a multi-day service outage, preventing customers from accessing streams, services, or their accounts.
In response to the attack, Dish Network shut down its internal network, engaged cybersecurity experts, and notified law enforcement. While the company has not confirmed whether a ransom was paid, statements suggest that negotiations may have occurred, as Dish received confirmation that the extracted data was deleted. The incident has also led to legal repercussions, with Dish facing a class action lawsuit related to its handling of the breach and the initial communication about the incident.
Exploitation in the Wild
The Black Basta ransomware group has been associated with several high-profile ransomware incidents, including the attack on Dish Network. Their exploitation methods involve sophisticated techniques for data exfiltration and ransom demands. The group's activities have been observed in various sectors, although specific APT groups have not been directly linked to this particular attack.
