Solana Bridge named “Wormhole” has been exploited and cryptocurrency amounting to $320 million has been stolen, according to reports released today, February 3rd.
The team posted a notification that the bridge had been hacked and 120,000 Ethereum encapsulated had been lost (Ethereum Encapsulated means a digital token representing Ethereum and based on a blockchain other than Ethereum), which was valued at approximately $320 million at the time.
The team added that Ethereum will be added to ensure that Ethereum encapsulated in the bridge is fully supported.
At the time of writing, the Wormhole team’s latest announcement is that the vulnerability has been patched and they’re working on getting things right.
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.

The biggest hack targeting a blockchain bridge to date:
Security researcher told samczsun about the vulnerability saying that the attacker either obtained the private keys, or he exploited the bridge in a cunning way.
How did the @wormholecrypto exploit work? I joined forces with @gf_256 and @ret2jazzy to reverse engineer the exploit, and now that it’s been patched we can finally share it with you👇 pic.twitter.com/lXwD0GLZ3N

He added that there was a similar transaction in Solana where the attacker blocked the Ethereum bridge.
The hacker basically exploited a weakness in the wETH encapsulated Ethereum mint and became the Ethereum encapsulated mint in the bridge without having to deposit Ethereum.
Tom Robinson, co-founder of blockchain analytics firm Elliptic, commented on the incident by saying:
This once again shows that the security of DeFi services has not reached the appropriate level for the huge amounts that are stored inside.
Blockchain transparency allows attackers to identify and exploit major bugs.
The developers of Wormhole have posted a message stating that there will be a reward for those who return the loot, stating:
We have noticed that you have been able to exploit the vulnerability.
We would like to offer you a white hat hacker agreement, and offer you a $10 million bug bounty for revealing the exploit details and returning your withdrawal.
The Wormhole bridge and platform were developed by Certus One, which was acquired by Jump Trading last August.
Impact of the breakout on Solana SOL price:
The bridge hack is the latest in a long list of problems facing Solana which includes 4 network outages in a few months.
SOL prices are down over the past eight hours by 10% from about $111 to $97 at the time of writing.
Solana is trading down 62.5% from its high recorded on November 6 at $260.
The Solana project is often described as an Ethereum killer, but this latest setback, along with network issues and faltering performance, makes this moniker moot.
