69,461 User Records Stolen in Coinbase Hack
Last week, Coinbase revealed that hackers had infiltrated customer records by bribing overseas support staff. The assailants allegedly demanded $20 million in exchange for withholding the stolen data—a sum the California-based company firmly declined to pay. Now, the Maine Attorney General’s records quantify the extent of the compromise.
Precisely 69,461 accounts were breached, including 217 belonging to Maine residents. The intrusion occurred on Dec. 26, 2024, attributed to what the company termed “insider wrongdoing.”
The breach was officially discovered on May 11, 2025. Coinbase included a template of its notification letter to affected Maine customers in the filing, submitted by “outside counsel” from Latham and Watkins LLP.
This revelation follows mounting apprehension that the breach may precipitate significant repercussions.
