Hacker steals $600 million from PolyNetwork

An unknown hacker stole $611 million in digital equivalent from PolyNetwork. According to representatives of the Chinese auditor BlockSec, the theft could have occurred because the private key used to sign inter-network messages was lost or a mistake was made in the process of signing messages.

Weak information security measures could have been the cause, leading to the loss of the private key. PolyNetwork uses a wallet that has multiple signatures for transactions at once. A hacker could have gained access to one of the signatures, but this is not the final conclusion.

In the end, the hacker who committed the largest theft announced that he would return the money in full. It is not clear what guided the attacker in his actions, but his final move would be this. He published his decision through a transaction to himself, attaching a text to it.
