Popular TV cable company impacted by data breach of up to 4 million personal records

The personal records of up to four million Time Warner Cable customers were possibly leaked via an unsecured Amazon server. The breach, which involved more than 600GB of data (the equivalent of 20 HD movies), was discovered by Cologne, Germany-based cybersecurity firm Kromtech.

Charter Communications bought Time Warner Cable last year, and the two companies currently operate under the Spectrum brand name. Prior to its purchase, Time Warner was the second-largest cable company in the U.S. and operated in 29 states.
