At the time of writing, more than $130 million has been stolen, before being transferred across numerous wallets. What do we currently know about this attack, which has already made the top 15 list of the largest amounts stolen from CEXs?
$130 million already stolen from crypto exchange Poloniex
New hack in the crypto ecosystem, and not the least: at the time of writing, more than $130 million has been stolen from one of the hot wallets of cryptocurrency exchange Poloniex.
The alert was first raised by blockchain security firm PeckShield, which invited Poloniex to take a look at a series of suspicious transactions:

Some 50 minutes later, Justin Sun, Poloniex’s owner since 2019, tweeted to confirm the incident, though without specifying an amount. The latter assured that Poloniex maintained a “stable state of financial health” and that all users affected by the attack would be reimbursed.
At the time, the amount of loot stolen was estimated at between $18 and $63 million. Now, according to data compiled by the Arkham Intelligence platform, the hacker’s various wallets currently hold some $130 million
It should also be noted that the hacker carried out numerous swaps on the Sun.io swap platform in order to obtain TRX, the TRON ecosystem token. The impact was directly felt on the TRX price, as we’re talking about tens of millions of dollars :

Since then, Poloniex and Justin Sun have communicated on X to inform the hacker that he has 7 days to return the funds and can keep 5% as a white hat reward. Should he fail to do so, legal action would be taken
