The U.K.-based crypto exchange has temporarily suspended all withdrawals from the platform after suffering a hack that compromised 5% of its total assets.
According to a security notice, the company detected “suspicious withdrawal activity” on Monday, 21 December. A security audit report showed large withdrawals of BTC, XRP, ZEC, USDT, ETC, and ETH from Exmo’s hot wallets. The affected hot wallets represent nearly 5% of the exchange’s total assets, the company said, adding that none of its cold wallets were affected.
After identifying the hackers’ wallets, Exmo called for other exchanges and services to block all of the accounts connected to the addresses.
The hack was reported to the London police, with the Exmo team saying that they are in contact with the Cybercrime team. The exchange will also conduct a thorough security review that will include all parts of their systems and data.
In the meantime, Exmo users were asked not to deposit any funds to the existing Exmo wallets. The exchange also noted that if any user funds were affected in today’s hack, the company would cover their losses.
