U.S. child- and family-oriented pay TV channel Nickelodeon has confirmed the legitimacy of the major data leak impacting its animation department that was initially reported late last month but noted that some of the exposed data were decades old, BleepingComputer reports. Investigation into the incident which was reported to involve a breach in January that resulted in the exfiltration of 500GB of media files and documents that were later exposed on a private Discord server is still underway, according to a Nickelodeon spokesperson. Files leaked by threat actors did not include user or employee data, noted the spokesperson, who added that none of the exposed files have been obtained from a recent breach of the company's systems. "The alleged leaked content appears related to production files only, not long-form content or employee or user data, and some of it appears to be decades old," said Nickelodeon.
