He asserts that withdrawals occurred immediately after the cross-chain bridge attack and followed a similar pattern.<\/p>\n<p>Heco Bridge was launched to provide low-cost inter-network interaction between Ethereum and HTX&#8217;s supported blockchain, Heco Chain. The project combined Tron protocols and the BitTorrent bridge ecosystem.<\/p>\n<p>On November 10, the Sun-owned Poloniex exchange was attacked for <a href=\"https:\/\/forklog.com\/en\/news\/poloniex-hack-losses-top-100-million\">$125 million in cryptocurrencies<\/a>. Then the head of the platform said there had been &#8220;successful identification and freezing of part of the assets linked to the hacker&#8217;s addresses.&#8221; He also proposed returning the coins for a reward of 5% of the stolen amount.<\/p>\n<p>Sun later said that the Poloniex team had identified the offender&#8217;s identity, and increased the payout to $10 million. If the hacker does not transfer the funds by November 25, law enforcement from several countries will begin taking action, he warned.<\/p>\n<p>Earlier, HTX <a href=\"https:\/\/forklog.com\/en\/news\/unknown-attackers-siphon-7-9-million-from-htxs-hot-wallet\">lost<\/a> 5000 ETH ($7.9 million at the time) due to a hot-wallet attack.
