CoinMarketCap Hack has reportedly leaked the email addresses of 3.1 million users

CoinMarketCap, a price-tracking website for cryptocurrencies, has been the victim of a hack that leaked the email addresses of 3.1 million users.

The information comes to light after hacked email addresses are traded and sold online in various hacking forums and is published by a website dedicated to tracking hacked and compromised online accounts.

CoinMarketCap, a subsidiary of Binance Cryptocurrency Exchange, confirmed that the list of leaked user accounts matched that of its users:

“CoinMarketCap has become aware that data batches are displayed online as a list of user accounts. Although the data lists we see are only email addresses, we have found a relationship with our customer base.”

On 12 October, while confirming the leak of the email addresses of 3.1 million (3,117,548) users, the company assured that hackers did not have access to any of the passwords in the account. A CoinMarketCap spokesperson said: “We have not received any evidence of data leaks from our own servers – we are actively investigating this issue and will update our customers as soon as we receive any new information.”

Despite confirmation, CoinMarketCap has yet to identify the exact cause of the hack.

CoinMarkatCap did not immediately respond to Cointelegraph’s request for comment.

A recent hack on Coinbase Crypto Exchange has compromised the accounts of 6,000 users.

The attack was the result of the Exchange’s use of the Multi-Factor Authentication (MFA) system, which suggests that hackers had access to the user’s email addresses. According to Coinbase, the attackers identified a weakness in the account recovery process:

“In this case, customers who use SMS text for two-factor authentication have taken advantage of Coinbase’s SMS account recovery process errors to obtain a third-party SMS two-factor authentication token and gain access to your account.”

Although the value of the assets stolen by Coinbase has not yet been revealed, the incident was hailed by thousands of formal complaints from account holders against the company.
