Ampersand, a television advertising sales and technology company jointly owned by the three largest U.S. cable operators, namely Comcast Corporation, Charter Communications, and Cox Communications, became the target of a disruptive ransomware attack in recent weeks. Ampersand, established in 1981, serves as a vital provider of viewership data to advertisers, offering insights into around 85 million households.The responsible party behind the attack has been attributed to the Black Basta ransomware gang, with cybersecurity researcher Dominic Alvieri sharing this information. While Ampersand did confirm the occurrence of a ransomware incident in an official statement, they have not disclosed the specific timeline of the attack or their stance on ransom payment. A company spokesperson conveyed that Ampersand recently encountered a ransomware incident that resulted in a temporary disruption of their regular operations. They successfully restored most of their standard business functions and are actively collaborating with third-party advisors and law enforcement to resolve this matter. In addition, although the process will require some time to complete, they are dedicated to conducting a comprehensive analysis and sincerely apologize for any concern or inconvenience the incident may have caused. Moreover, the Black Basta ransomware gang has not specified the extent of data stolen from the company and has not released any samples of the information they may have accessed.
