This is exactly why KYC is so dangerous. 5$ wrench attack incoming.

What happened Criminals targeted our customer support agents overseas. They used cash offers to convince a small group of insiders to copy data in our customer support tools for less than 1% of Coinbase monthly transacting users. Their aim was to gather a customer list they could contact while pretending to be Coinbase—tricking people into handing over their crypto. They then tried to extort Coinbase for $20 million to cover this up. We said no.

What they got

Name, address, phone, and email
Masked Social Security (last 4 digits only)
Masked bank‑account numbers and some bank account identifiers
Government‑ID images (e.g., driver’s license, passport)
Account data (balance snapshots and transaction history)
Limited corporate data (including documents, training material, and communications available to support agents)

@mega_dreamer what does this mean for the coinbase hack market. I added some shares today but didn't want to buy too much because they didn't give a specific number of affected users. <1% but they have a lot of users so that is likely more than 10k as specified in the market criteria.

I am not sure if they will resolve yes though because we don’t have an actual user count. Although it is highly likely it is over 10k considering how many users they have.

This is not a hack. Some support agents got bribed to hand out customer data.

What we are doing about it

Extra customer safeguards — Flagged accounts now require additional ID checks on large withdrawals and include mandatory scam‑awareness prompts. As we monitor high risk transactions, you may experience delays.

Come on CoinBase, your answer to the issue is to request more personal information. and government ID

Let this be a warning that any other KYC service is prone to the same vulnerabilities.
