Lock a photo of a city

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

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

However, it wasn’t until February 28 that DISH finally confirmed to have suffered a ransomware attackwith multiple sources telling BleepingComputer that the Black Basta ransomware gang was responsible.

The other big news was a report that the The US Marshals Service suffered a ransomware attack, including data theft. It is unclear which ransomware operation is behind the attack.

Finally, the White House unveiled its new US national cybersecurity strategywith a focus on targeting ransomware operations.

Other ransomware attacks we learned more about this week include those on the City of Oakland, the Indigo bookstore chain, Tennessee State University and University of Southeast Louisianaand the Clop data theft at Hatch Bank.
