(Reuters) – TV station operator Sinclair Broadcast Group said on Monday that it had found that some of its servers and workstations had been encrypted with ransomware, disrupting office networks.
Sinclair said it was investigating what information ransomware affected and had notified law enforcement and other government agencies.
Ransom software works by encrypting victims' data and may include locking a company's network or stealing data. Typically, hackers will offer the victim a key in exchange for cryptocurrency payments that can run into the hundreds of thousands or even millions of dollars.
With increasingly frequent ransomware attacks on companies, President Joe Biden has made cyber security a top priority and is coordinating with other countries to combat the threat.
Colonial Pipeline was hit by a crippling cyberattack earlier this year that disrupted fuel supplies for nearly a week, leaving thousands of gas stations in the southeastern United States without fuel.
Sinclair, the second largest US television station operator, said the ransomware attack could disrupt ads from its local broadcast stations and that the company could not currently determine if it would have a significant impact on its business or financial results.
