XCarnival, a liquidity provider for the Ethereum ecosystem, recovered 1,467 Ether (ETH) just a day after suffering an exploit that drained 3,087 ETH, worth roughly $3.8 million, from the protocol.

Blockchain investigator Peckshield pastebėjau the XCarnival hack as it came across a stream of transactions that eventually bled 3,087 ETH from the protocol. Explaining the nature of the exploit, Peckshield stated:

„Įsilaužimas tapo įmanomas leidžiant atšauktą įkeistą NFT vis dar naudoti kaip užstatą, kurį įsilaužėlis išnaudoja, kad pašalintų turtą iš fondo.

Soon after the revelation, XCarnival proactively informed the users about the hack while temporarily suspending a part of its services to counter the annoying attack. The protocol also offered the hacker 1,500 ETH as a bounty in addition to offering exemption from legal proceedings.

Eventually, XCarnival suspended the smart contracts and deposit and borrowing features until it could identify and rectify the internal bug that made the hack possible. According to Packshield, the hacker used a previously withdrawn pledged nesukeliamas ženklas (NFT) from the Bored Ape Yacht Club (BAYC) collection as collateral to drain the assets.

What could have been the story of the year turned out to be a disappointment after efforts from a white hat hacker to recover a locked phone full of Bitcoin (BTC) resulted in the discovery of just 0.00300861 BTC.

As Cointelegraph reported, Joe Grand, a computer engineer and hardware hacker, traveled from Portland to Seattle to potentially recover BTC from a Samsung Galaxy SIII phone owned by Lavar, a local bus operator.

Meticulous efforts that involved micro soldering, downloading the memory and discovering the Samsung’s swipe pattern for access, Lavar opened his MyCelium Bitcoin wallet and discovered only 0.00300861 BTC — worth $105 at the time, down to roughly $63 at the time of publication.
