U.S. manga and anime publisher Viz Media, known for releasing hit manga such as Demon Slayer, Chainsaw Man and Naruto, was reportedly targeted in a major data breach that allegedly compromised more than 250GB of sensitive corporate information.
This incident was brought to light by Cybersecurity outlet CyberNews, stating that hackers claimed to have accessed a senior executive’s Google-linked account.
According to the report, the attackers advertised the breach on an underground data-leak forum used by cybercriminals and initial access brokers.
A screenshot shared by the outlet shows that the stolen access is tied to a Google account associated with Viz Media, with the attackers offering to sell the data for a five-figure price. A small portion of this data was posted publicly, and the remainder is reportedly being marketed for sale.
CyberNews’ research team analyzed the hackers’ post and concluded that the breach likely stemmed from a single compromised account belonging to a senior Viz Media official. The attackers allegedly gained broad internal access as a result of the executive’s high-level privileges.
“It could’ve been that this person fell victim to a social engineering attack leading to unauthorized access to the company’s internal systems.”
This latest incident follows a separate breach earlier this year. In January 2025, Viz Media’s official X account was hacked, with the attackers posting messages promoting cryptocurrency and a so-called “$VIZ” digital token.
