CertiK, a blockchain auditing and security company, suggests the hacker was able to exploit a security flaw in Qubit’s smart contract code that let them send in a deposit of 0 ETH and withdraw almost $80 million in Binance Coin in return.

“As we move from an Ethereum-dominant world to a truly multi-chain world, bridges will only become more important,” CertiK analysts wrote. “People need to move funds from one blockchain to another, but they need to do so in ways that are not susceptible to hackers who can steal more than [$80 million].”

A statement posted by the Qubit Finance team on Twitter directly appealed to the hacker, asking them to negotiate with the team in order to minimize losses for the Qubit community.

Qubit’s incident report also stated that the team was attempting to offer the hacker the maximum reward possible under their bug bounty program.

Blockchain security company CertiK released a detailed explanation of how the attack occurred and has been tracking the stolen funds as the hackers move them to different accounts.

“For the non-technical readers, essentially what the attacker did is take advantage of a logical error in Qubit Finance’s code that allowed them to input malicious data and withdraw tokens on Binance Smart Chain when none were deposited on Ethereum,” CertiK explained.

DeFiYield keeps a running list of attacks on DeFi platforms, ranking the attack on Qubit as the seventh largest after Compound Labs, BadgerDAO, Cream Finance, Boy X Highspeed, Vulcan Forged, and Poly Network.

We suggest you negotiate instantly with us earlier than taking any additional motion. The exploit and lack of funds have a profound impact on hundreds of actual individuals. If the utmost bounty supply just isn’t what you might be searching for, we’re open to have a dialog.

Let’s determine a state of affairs,” the Qubit Finance Group wrote.

The corporate later defined in a weblog publish that their Qubit protocol “was topic to an exploit to our QBridge deposit operate.”

“The attacker known as the QBridge deposit operate on the ethereum community, which calls the deposit operate QBridgeHandler. QBridgeHandler ought to obtain the WETH token, which is the unique tokenAddress, and if the one who carried out the tx doesn’t have a WETH token, the switch shouldn’t happen,” the corporate defined.

Qubit later upped its offer to $1 million, and then to $2 million with the promise that the attacker would not be prosecuted.

We have secured the funds to be able to pay a bounty of $2,000,000 in line with the historically high Polygon bounty and our total limit, without prosecution. We continue to work with security firms throughout the ecosystem and independently to resolve this exploit. The entire Qubit community is hopeful you will do the right thing and accept the offer.

To be honest, if I were criminally minded and had stolen $80 million from Qubit, I might be very happy holding out, and seeing if the company could offer me a reward significantly closer to $80 million…

News of the hack is, of course, potentially catastrophic for Qubit and very worrying for its users.

The platform offers a bounty of $250,000 in exchange for the stolen funds.

“We suggest that you negotiate directly with us before taking any further action. The exploit and the loss of funds have a profound effect on thousands of real people. If the maximum premium isn’t what you’re looking for, we’re open to a conversation.
Let’s try to find a solution,” writes Qubit’s finance team.
