Panasonic’s Data Breach Leaves Open Questions
November 30, 2021

Consumer electronics giant Panasonic’s data breach raises questions, researchers say – given that more than two weeks after the incident was discovered, it’s unclear if customers’ personal information has been impacted.

On Friday, Panasonic confirmed that its “network was illegally accessed by a third party on November 11, 2021,” and that “some data on a file server had been accessed during the intrusion.”

Further details on the breach are thin, with Panasonic’s bare-bones statement offering very little in the way of technical detail or timeline. However, local reports picked up by the Record indicated that the breach had been ongoing since June, giving attackers plenty of time to knock around in the Japanese behemoth’s files.

However, Jake Williams, co-founder and CTO at BreachQuest, speculated that the intrusion could balloon into a major incident.

“As is typical in these early-stage incident reports, there are many unknowns,” he said via email. “In this case however, there are already red flags. NHK reported that internal network monitoring was the source of the incident detection, seemingly implying that the depth of intrusion is more than a misconfigured external server…Those [misconfiguration] cases at least have localized impact because there is no threat of threat actor lateral movement deeper into the network.”

John Bambenek, principal threat hunter at Netenrich, also noted that the four-month gap between breach and detection is concerning.

“While attacks on Japanese companies are continuing, the fact that the initial infection occurred in June and wasn’t detected until November demonstrates that companies are continuing to lag behind attackers,” he said via email. “Breaches need to be detected in hours, not months.”
