Coinbase Data Leak (May 2025): While funds were not directly stolen from user accounts via this breach (private keys and passwords were not accessed), sensitive personal data (names, addresses, SSN digits, government IDs) of a subset of customers was improperly accessed, and criminals are now using this data for social engineering attacks to trick users into sending their crypto. Coinbase is expecting to spend hundreds of millions on remediation and customer reimbursements.
Bybit (February 2025): While primarily impacting construction email list Ethereum ($1.4 billion ETH stolen), this was a massive breach illustrating the ongoing risks at centralized exchanges.
Important Distinction:
Bitcoin's core blockchain technology is highly secure against data breaches. Its decentralization and cryptographic principles make it virtually impossible to "hack" the ledger itself.
"Bitcoin data breaches" refer to incidents where centralized entities (exchanges, wallets, other services) holding Bitcoin or managing user data related to Bitcoin, are compromised. This leads to the theft of funds, exposure of personal user data, or both.
Users are always advised to take strong security measures for their own crypto holdings, especially by using non-custodial wallets where they control their private keys, and enabling multi-factor authentication (MFA) on any exchange accounts.
