U.K.-based cryptocurrency exchange EXMO revealed Monday that it has suffered a security incident, in which its hot wallets have been compromised leading to the loss of nearly 5% of its total assets. Due to an apparent cyber attack the company has temporarily suspended all withdrawal activity.
“We are still investigating the incident, but as of now, the security audit report showed that some amounts of BTC, XRP, ZEC, USDT, ETC and ETH in EXMO’s hot wallets were transferred out of the exchange. We reacted immediately and re-deployed hot wallets,” the company said in a statement.
EXMO also stressed that the assets in the cold wallets have not been affected by the attack.
The exchange asked users to not deposit funds in existing EXMO wallets for the time being and asked all the services and exchanges to block all the accounts that are connected to the affected wallets.
The company said it reported the security breach to the London police and will “conduct a thorough security review that will include all parts of our systems and data.”
