Key takeaways:

  • For experienced users who had registered the six tokens (WETH, PERI, OMT, WBNB, MATIC, AVAX) in their addresses, the identified vulnerability remains critical.
  • For $1.5 million, a flaw in the Multichain protocol (which affects users who haven’t cancelled permissions) was exploited.
  • One hacker made off with $200,000, but is now proposing to refund the majority of the money to the original owner.

Investors are constantly being cautioned to take caution, especially when investing in new cryptocurrency projects because hackers are on the search for vulnerable crypto ventures to exploit.

Several allegations have surfaced claiming that hackers stole millions of dollars in cryptocurrency as a result of a serious flaw discovered in the project. Similarly, the project’s founders take funds from its pool of investors by exploiting its coding, then depart the project through a method known as rug pulling.

AnyswapV3ERC20/AnyswapV4ERC20/AnyswapV5ERC20 are all vulnerable to another critical vulnerability, according to Peckshield.

And @MultichainOrg uses a privileged function to *DRAIN* funds from multiple chain-bridges ($44.5 million: $38 million in #AVAX, $5 million in #BSC, $1.5 million in #Polygon).

Multichain is the web3’s Ultimate Router. It’s a system designed to allow for arbitrary cross-chain interactions.

On July 20th, 2020, Multichain was created as Anyswap to address the clear need for distinct and diverse blockchains to communicate with one another. Each blockchain has its own community and development ecosystem, as well as its own set of services. We need a rapid, secure, economical, and reliable mechanism to exchange value, data, and exercise control between the chains for our industry to advance to the next level for consumers.

For experienced users who had approved the six tokens (WETH, PERI, OMT, WBNB, MATIC, AVAX) in their addresses, the identified vulnerability remains critical.

They urgently advise these individuals to immediately rescind their approvals before sending any of these 6 tokens back to their wallets.

Otherwise, these six tokens in your address are constantly at risk, and the danger will be removed immediately if approvals are revoked.

The continued exploitation of the cross-chain protocol Multichain has already totaled $1.5 million, according to ZenGo co-founder Tal Be’ery.

The old contracts with the vulnerability have been discarded, and new contracts with the issue patched are being produced and will be launched later.

Because the other token contracts on Multichain have been proved to be safe, people can continue to utilise Multichain bridges with confidence.

The following actions were made to address the situation:

1. The development team monitors the impacted users’ assets and all other funds 24 hours a day, 7 days a week.

2. Notifications and updates on all social media networks

3. Use several platforms to reach and notify all affected users.

4. Send an onchain alert message to the addresses that are affected.

5. Etherscan, Polygonscan, and BSCscan launch alert banners

6. The Help Centre provides support 24 hours a day, 7 days a week.

A hacker takes $200,000 using a Multichain exploit and promises the victim 80% of the money back

Multiple blockchain wallets are taking advantage of a protocol flaw, with one or more hackers behind the attacks. One of the hackers who profited from the exploit by stealing $200,000 expressed regret. They claim to be a white hacker and have offered to restore 80% of the funds taken.

“Whitehat here, provide me the tx you lost your wealth, and I give you 80% back,” the hacker said in a blockchain transaction. The rest are money-saving suggestions for me.” Multichain has since responded to the hacker, expressing hope that the monies will be returned to a blockchain address mentioned in the message.

It’s unknown whether this hacker was involved in any other thefts. When questioned if the hacker controls the wallet that was used to steal $1.43 million, Multichain responded it’s plausible. “Can’t really know,” Be’ery remarked.

What we think is, this is far from over:
