The Week in Ransomware – March 3rd 2023 – Wide impact attacks

This week was highlighted by a massive BlackBasta ransomware attack targeting DISH Network and taking down numerous subsidiaries, including SlingTV and Boost Mobile.

The attack started on February 23rd, forcing the company to shut down portions of its IT systems, causing widespread outages among its services.

However, it wasn’t until February 28th that DISH finally confirmed that they suffered a ransomware attack, with multiple sources telling that the Black Basta ransomware gang was responsible.

The other big news item was a report that the U.S. Marshals service suffered a ransomware attack, including data theft. It is not known what ransomware operation is behind the attack.

Finally, the White House unveiled its new U.S. national cybersecurity strategy, with a strong emphasis on targeting ransomware operations.

Other ransomware attacks we learned more about this week include ones on the City of Oakland, the Indigo book store chain, Tennessee State University and Southeastern Louisiana University, and the Clop data theft at Hatch Bank.
