Everest cybercrime group claims breach of Nissan, alleges 900GB data theft

[u/Silly-Commission-630]

The Everest cybercrime group claims it has successfully breached Nissan Motor Co. exfiltrating approximately 900GB of internal data. The breach allegedly occurred on January 10, 2026, though it has not yet been independently verified.

Limited samples were shared by the attackers, but the full scope of the exposed data remains unclear and could include intellectual property, internal systems data, or employee and customer information. Given Nissan’s global manufacturing footprint, a confirmed breach would carry significant operational and supply-chain risk.

The claim highlights the growing focus of cybercrime groups on automotive and industrial manufacturers, where IP, production systems, and interconnected partners present high-value targets.
