A Coinbase data breach filing with the Maine Attorney General finally gives us some more detail than Coinbase’s vague “less than 1% of monthly transacting users”. 69,461 people were affected, and Coinbase says the data breach occurred on December 26, 2024.

It took them almost five months between the incident and the incident disclosure, although the company has since admitted it knew customer support agents were suspiciously accessing customer data as far back as January.

Security researchers who have spent months trying to call Coinbase’s attention to serious issues at the company are disputing Coinbase’s claims about the timing of the breach. “Threat actors had ongoing access via multiple insiders over a prolonged period of time.”

Oh good apparently now the Coinbase breach happened on Dec 26, 2024.

LOL

So since Coinbase won't be straight with you, I will. 

Threat actors had ongoing access via multiple insiders over a prolonged period of time. (Screenshot of Maine AG notification)
As evidence, here's a very small cutout of one high value customer's Coinbase account.

This wasn't pulled on Dec 26, 2024 honey.

The SEC requires material cybersecurity incidents be disclosed within four business days; state laws often have a 30-day disclosure deadline. It’s not clear if customers outside the US were affected; if so, other disclosure laws may apply.

Coinbase was aware that support reps were suspiciously accessing customer data when its CEO tweeted that the CFPB should be "deleted". Among other things, the CFPB has pursued legal action against financial companies that failed to secure sensitive customer data.

Tweet by Brian Armstrong @brian_armstrong on February 8, 2025
100% the right call

The CFPB is unconstitutional on the face of it. And even if it wasn’t, it should be deleted as we already have DOJ to prosecute fraud, and (many) other financial services regulators. It’s an activist organization that has done enormous harm to the country.

Quoted tweet: Kekius Maximus @elonmusk
CFPB RIP 🪦

Readers added context they thought people might want to know
The Supreme Court, ruled (7-2 decision) that the CFPB's funding mechanism does not violate the Constitution. Justice Thomas wrote the majority opinion, stating that the CFPB's funding fits w/in the framework of congressional appropriations.

In April, Coinbase announced changes to its user agreement that added two clauses further limiting class action lawsuits and requiring lawsuits to be filed in New York. The changes apply to disputes initiated after May 15.

On May 14, Coinbase disclosed a data breach.

Coinbase announces it's joining the S&P 500 and then announces a serious data breach two days later.

oof.

The only data Coinbase has disclosed about the scale of the breach is that it affects "less than 1% of Coinbase monthly transacting users", which seems super cagey.
