Binance Says a Hacker Who Claims to Have Hacked the Hacker Who Stole 7,000 Bitcoin from the Exchange Is Demanding a Blackmail Payment of 300 Bitcoin

During a month-long series of conversations with CoinDesk, a hacker using the pseudonym of Bnatov Platon claimed to have allegedly hacked individuals behind an earlier hack in which 7,000 bitcoin was stolen from Binance, the world’s largest cryptocurrency exchange. Platon produced photos that he claimed to have hacked from the hacker and then demanded a bug bounty from the exchange. Binance says that an unidentified hacker has threatened and harassed the company, demanding 300 Bitcoin, worth around $3.6 million, in exchange for withholding 10,000 photos that bear similarity to its data. Binance is investigating this case for legitimacy and relevancy.

Binance Says Hack of 10,000 Customers’ Data Stemmed From Third-Party Vendor, Gives Affected Victims Lifetime VIP Membership, Urges Them to Apply for New I.D. Documents

Cryptocurrency exchange Binance confirmed that a breach resulting in hackers distributing the Know Your Customer (KYC) images of hundreds of its users online and to media outlets was caused one of the company’s third-party vendors.  Before leaking the images online, the alleged hacker threatened the exchange to release KYC data of its 10,000 customers if the company did not pay 300 Bitcoins worth over $3 million at today’s exchange value. Binance also said that multiple leaked images were photoshopped and did not match the KYC images in its database. The exchange began contacting potential victims with “guidance on privacy protection and restitution,” and recommended that affected users should apply for new identification documents in their respective region. Binance is also offering a lifetime VIP membership to all its users affected.

Large Scale Security Breach at Binance Results in Theft of 7,000 Bitcoin Worth $41 Million

Cryptocurrency exchange Binance announced that a “large scale security breach” was discovered earlier on May 7 with malicious hackers able to access user API keys, two-factor authentication codes and potentially other information to steal 7,000 bitcoin worth around $41 million. The exchange may not yet have identified all impacted accounts although the breach only impacted Binance’s hot wallet, which contains roughly 2 percent of the exchange’s total bitcoin holdings. The exchange was frozen after the discovery and Binance said it will use its Secure Asset Fund for Users (SAFU fund) to cover the loss, which won’t impact users.

Ethereum Classic Currency Pulled From Coinbase Following Potential 51% Attack Resulting in Double Spends Worth $1.1 Million (And Counting)

Cryptocurrency exchange Coinbase has halted all Ethereum Classic (ETC) transactions because of a potential 51 percent attack after which it observed double spends of 219,500 ETC worth around $1.1 million as of the latest reports. The attacks are still ongoing. A 51% attack is when a person or group controls more than half of a cryptocurrency’s hashing or computing power and gives them control over which transactions get processed on the blockchain, allowing them to double spend or reverse transaction they made while on the network, making it appear that they still have coins they just spent.
