Panasonic discloses data breach after network hack

Japanese multinational conglomerate Panasonic disclosed a security breach after unknown threat actors gained access to servers on its network this month.

"Panasonic Corporation has confirmed that its network was illegally accessed by a third party on November 11, 2021," the company said in a press release issued Friday.

"As the result of an internal investigation, it was determined that some data on a file server had been accessed during the intrusion."

Panasonic has reported the incident to the relevant authorities and has taken measures to prevent access to its network from external servers.

The Japanese electronics giant has also hired the services of a third party to investigate the attack—which Panasonic tagged as a "leak" in the press release—and find if any of the data accessed during the intrusion includes customer personal information.

"In addition to conducting its own investigation, Panasonic is currently working with a specialist third-party organization to investigate the leak and determine if the breach involved customers' personal information and/or sensitive information related to social infrastructure," the company added.

A Panasonic spokesperson was not immediately available for comment when contacted by BleepingComputer.

Panasonic would like to express its sincerest apologies for any concern or inconvenience resulting from this incident. — Panasonic

Panasonic servers reportedly hacked in June

While the press release issued doesn't include many details regarding the attack timeline, Japanese outlets, including Mainichi and NHK, said the attackers had access to Panasonic's servers between June and November, as first reported by The Record.

Furthermore, they gained access to customer and employee sensitive information until Panasonic spotted the malicious activity on November 11.

The attack on Panasonic's server is part of a long series of other incidents involving Japanese companies in recent years.

KawasakiNECMitsubishi Electric, and defense contractors Kobe Steel and Pasco have also disclosed security incidents and, in some cases, even data leaks.


Update January 10: Panasonic confirmed [PDF] the attackers gained access to personal info belonging to interns and job candidates, stored on file servers in Japan.

Some personal information, relating to candidates who applied for employment at the company or participated in internships at certain divisions of the company, did reside on the targeted server. Impacted persons are being informed.
