  • •Binance believes the claims are likely a scam and found no evidence of a breach.

Binance has refuted claims of a data breach involving 335 million user records, which were allegedly put up for sale by a threat actor claiming to be associated with the ShinyHunters group. The attacker demanded $900,000 in exchange for not disclosing the data, which purportedly includes KYC documents, passwords, and private keys. Binance stated that a preliminary review found no evidence of a breach, asserting that the claims are likely a scam. The company noted inconsistencies in the claims, such as their storage practices for user data, and suggested that the data may have been collected via malware on users' devices. The exchange is continuing its investigation into the matter. This incident follows a recent confirmed breach attributed to North Korean hackers that resulted in a significant cryptocurrency theft.
