CoinMarketCap hack reportedly leaks 3.1 million user email addresses

The information came to light after hacked CoinMarketCap email addresses were discovered to be traded and sold online on various hacking forums. And CoinMarketCap itself has confirmed that the leaked list of user accounts matches its user base.

“CoinMarketCap has become aware that batches of data have shown up online purporting to be a list of user accounts. While the data lists we have seen are only email addresses, we have found a correlation with our subscriber base”, they stated.

Despite confirming the leak of 3.1 million (3,117,548) user email addresses on October 12, the company has ensured that hackers did not gain access to any account passwords.

“We have not found any evidence of a data leak from our servers — we are actively investigating this issue and will update our subscribers as soon as we have any new information,” CoinMarketCap spokesperson said.

Although it has been confirmed, CoinMarketCap has yet to determine the exact cause of the hack.

As AZCoin News reported, a recent hack on cryptocurrency exchange Coinbase resulted in 6,000 user accounts being compromised. The attack resulted from exploiting the exchange’s multi-factor authentication (MFA) system, suggesting that hackers had access to users’ email addresses. Reportedly, attackers have identified vulnerabilities in the account recovery process.

“In this incident, for customers who use SMS texts for two-factor authentication, the third party took advantage of a flaw in Coinbase’s SMS Account Recovery process to receive an SMS two-factor authentication token and gain access to your account,” Coinbase stated.

Although the value of the stolen assets has yet to be disclosed by Coinbase, thousands of formal complaints from account holders have been filed against the company. And now it seems that CoinMarketCap is also falling into that situation.
