Nothing like a nine-figure exchange hack to cool the pump-induced euphoria.
Justin Sun’s exchange Poloniex had its hot wallets drained of $126M today.
Nothing to see here, folks.
After another half hour, Justin Sun responded more directly, promising to cover losses:
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.
Will it be enough to either tempt, or force, a return of the loot this time?
As ever, exchange hacks are often down to off-chain attack vectors, with the aim of gaining access to a device or an employee in order to extract private keys.
Organised threat actors, such as North Korea’s Lazarus Group, are well-versed in a variety of methods to carry out extensive phishing campaigns. So far this year, over $250M has been lost in incidents linked to the group, including attacks on Atomic Wallet, AlphaPo, Stake and CoinEx.
Could this be another big payday for the DPRK?
The attack continued on Ethereum, TRON and BTC, with a total of $126M lost, according to Arkham’s attacker profile (which displays totals of $59.2M, $48.6M, $18.6M held on the three chains, respectively).
Main attacker address (ETH): 0x0a5984f86200415894821bfefc1c1de036dbf9e7
Main attaker address (TRON): TKK6d1YALy8HCSoCSWWd1ZJhyC9NPPx4wa

Dispersal of tokens among many hacker addresses on Ethereum (labelled 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15) which were used to swap out tokens to ETH and hold it, or further it disperse to new addresses.
The largest asset losses were of 33M USDT (22M on TRON and 11M on ETH), 4900 ETH ($10M) on Ethereum, $18.6M of native BTC and a further $14M of BTC on TRON and $5M USDC on Ethereum.
SlowMist compiled a lengthy (though not yet complete) breakdown of assets stolen.
The hacker’s actions on-chain had some unexpected results.
In swapping out (freezable) the USDT stolen on Tron to TRX, the attacker pumped Justin Sun’s bags by 25%. At least it makes up for some of the losses he’s promised to cover…
And in the rush to liquidate stolen assets, the attacker lost almost $2.6M worth of Golem Network’s GLM by transferring it directly to the token’s contract.
Luckily for Justin, he ultimately managed to escape shelling out for a costly compensation scheme when the funds were returned less than two weeks later.
Now, he has promised to cover losses over 10x larger…
…while offering a (lower-than-the-going-rate) 5% bounty and a 7-day grace period to think it over.
Is he confident the hacker will take him up on it? Or feeling over-confident after getting lucky last time?
How deep do Sun’s pockets go?
