Crypto exchange Coinsquare acknowledges user data breach

The Canadian-based cryptocurrency exchange Coinsquare reportedly suffered a breach. The platform says that user assets were not affected, according to CoinDesk.

In an email to clients, the exchange said it was an ‘data incident’ in which a third party gained unauthorized access to users’ personal information.

According to the statement, the attackers obtained ‘names, email addresses, residential addresses, phone numbers, dates of birth, wallets, transaction histories and account balances’ of customers.

On November 19, the exchange paused operations, including withdrawals, after detecting the vulnerability.

Earlier this morning, we detected unusual activity on our platform and out of an abundance of caution, we decided to undergo an unscheduled maintenance period while we address this issue.

“Earlier this morning we detected unusual activity on our platform and, for security reasons, decided to conduct unscheduled maintenance while we address this issue,” the team said.

She assured that “100% of client funds are safely stored in cold wallets” and were not affected by the incident.

Developers restored platform functionality only by November 26. Users still do not have access to the transaction history. The team says it will restore the feature soon.

Full service has been restored on web and mobile, including fiat and crypto deposits/withdrawals. We thank you for your patience throughout the day and continued support

A number of clients noted a request for re-verification on the platform, as well as a glitch in the 2FA settings.

“Passwords have not been exposed. We have no evidence that the attacker viewed this information,” the team said in the letter.

Earlier in July, the data breach affected the bankrupt Celsius Network.
