Crypto exchange AscendEX confirms weekend hack
15:08, 13 December 2021
Cryptocurrency exchange AscendEX has reportedly lost up to $77.7m (£58.6m) in a hack which took place over the weekend.
“On 11 December at approximately 22:00 UTC, AscendEX identified a number of unauthorised transfers from one of our hot wallets,” AscendEX said in a series of Tweets.
“A security response was initiated immediately. Cold wallets are unaffected, and any impacted users will be reimbursed 100%.”
The exchange also outlined remediation steps it was taking in the Twitter posts.
“We are working alongside chain analytics firms and law enforcement to monitor the transferred assets. We are also in close contact with other CEXs to blacklist wallets associated with the incident.”
Security research firm PeckShield estimated AscendEX’s losses at $77.7m across three blockchains: $60m on Ethereum (ETH), $9.2m on Binance Smart Chain (BSC) and $8.5m on Polygon (MATIC).
