Hackers stealing cryptocurrency is a regular event in the last couple of years. But in a bizarre incident, a hacker who stole $600 million worth of cryptocurrency earlier this week, returned $260 million of them. Here’s what happened. A hacker took advantage of a bug in Poly Network, a decentralized finance platform that lets you exchange various tokens, and stole $600 million in various digital currencies. This was touted as one of the biggest hacks in the decentralized world. A day later, the network tweeted that the unknown hacker has returned $1 million in Polygon, $3 million in Ethereum, and $256 million in BSC. However, more than $350 million worth of cryptocurrency still remains with the hacker.
The remainings are $269M on Ethereum, $84M on Polygon — Poly Network (@PolyNetwork2) August 11, 2021 As ZDNet noted, security researchers believe the attack is tied to a Poly Network privileged contract called the “EthCrossChainManager.” You can read more about the technicalities of the hack here. Tom Robinson, the founder blockchains solutions company Elliptic, has shared a Q & A with the alleged hacker. In the post, the hacker claims that they didn’t want to cause any panic and wasn’t interested in the money:
— Tom Robinson (@tomrobin) August 11, 2021 One of the theories behind hackers returning the money is Poly Network’s threat of legal action. Robinson opined that the transparency of blockchain makes it difficult to launder the money, so the hacker decided to return it instead. We’ll have to wait and see they return all the money.
