Crypto exchange Poloniex has suffered a major security breach, with hackers draining around $125 million worth of funds from the platform’s hot wallets.
The hack, which blockchain analytics firm PeckShield first detected, saw the attackers steal an estimated $56 million in ETH, $48 million in TRON (TRX), and $18 million in Bitcoin.
A few minutes after PeckShield’s report, Poloniex posted a tweet saying it had “disabled wallets for maintenance.” However, Tron founder Justin Sun, who acquired Poloniex in 2019, confirmed the breach in a tweet, saying that the exchange would “fully reimburse” affected users.
We are currently investigating the Poloniex hack incident. Poloniex maintains a healthy financial position and will fully reimburse the affected funds. Additionally, we are exploring opportunities for collaboration with other exchanges to facilitate the recovery of these funds.

The exchange is also offering hackers a 5% ‘white hat’ bounty to return stolen funds.
Arkham data shows that the Poloniex hacker bought $20 million in TRX after the breach, driving the token’s price up by over 20%.
Hours after the hack, the attacker appears to have made a $2.5 million mistake, accidentally sending Golem tokens directly to the token’s smart contract and losing access to the funds.
This is the second security incident for a Sun-owned exchange in recent months. In September, crypto exchange HTX (previously Huobi) lost around $8 million in Ether to hackers. A few weeks later, the hacker returned the stolen funds and received a 250 ETH “whitehat bonus”.
