The platform Wormhole is a provider of a connection between different blockchain networks.

A number of tweets posted by the Wormhole page say that the thieves have stolen approximately $320 million in cryptocurrency. Soon after that happened, the platform was shut down for maintenance.

The wormhole network was exploited for 120k wETH.

ETH will be added over the next hours to ensure wETH is backed 1:1. More details to come shortly.

We are working to get the network back up quickly. Thanks for your patience.

In a statement provided by Elliptic, it was announced that this is the second-largest crypto theft after the one from the Defi service. In a blog post Elliptic said:

“The exploit appears to have allowed the attacker to mint 120,000 wrapped ETH on the Solana blockchain, 93,750 ETH of which was then transferred to the Ethereum blockchain.”

According to a message, Wormhole’s developers offered the hacker $10 million if they return the cryptocurrency.

A couple of hours after the exploit, it was reported that the vulnerability had been patched and restoring of the network was in process.
