Yuga Labs Just Pulled Off A $500,000 Crypto Heist — Against These Hackers
Yuga Labs, the corporate behind Bored Ape Yacht Club and CryptoPunks, accomplished a covert whitehat operation on June 8 to rescue 68 blue-chip NFTs — price greater than $500,000 — from an energetic exploit focusing on Flooring Protocol, deploying its personal funds and appearing earlier than extra attackers might drain property that included a number of the most dear tokens in NFT historical past.
Yuga Labs CEO Michael Figge (@mfigge) announced the profitable operation on X, publishing a full stock of the rescued property now held within the firm’s custody: 29 Bored Ape Yacht Club NFTs, 4 Mutant Apes, one Bored Ape Kennel Club token, two CryptoPunks, one Azuki, two Elementals, 26 Captains, one Moonbird, and two Doodles. “We’ve simply completed a whitehat operation on an exploit found in Flooring Protocol,” Figge wrote, noting that Yuga Labs VP of Blockchain 0xQuit (@0xQuit) led the on-chain restoration effort.
The operation was funded by way of GrailsOTC, Yuga Labs’ over-the-counter buying and selling desk — which Figge mentioned he “quietly instructed” to entrance the capital and NFTs wanted to drag the at-risk property out of the protocol earlier than extra unhealthy actors might act on the identical vulnerability. The firm plans to return all 68 NFTs to their authentic house owners as soon as a technical repair has been deployed and verified.
How The Crypto Exploit Worked
The mechanics of the assault, explained in a technical thread by 0xQuit on X, reveal a complicated vulnerability embedded in Flooring Protocol’s core accounting logic. A malicious actor turned a mud quantity of WETH — a negligible amount — right into a near-infinite fpToken stability by exploiting an edge case in how the protocol dealt with token possession data. The attacker then used the inflated stability to empty Flooring swimming pools, with a subsequent opportunist scooping up the now-depleted pool tokens and exchanging them for the underlying NFTs.
The deeper vulnerability, per 0xQuit’s publish, got here from packed possession and indexing logic — a technical design selection the place a malicious token ID might make possession verification checks go whereas downstream accounting recorded a special outcome fully, creating what he described as “ghost possession.” An unchecked stability replace then precipitated an arithmetic underflow, handing the attacker a stability far bigger than legitimately entitled. Once that inflated stability was in place, token costs may very well be pushed close to zero and liquidity extracted from the pool at will.
After reviewing the preliminary assault path, Yuga Labs’ staff recognized a second, broader vulnerability that uncovered extra NFT swimming pools not but touched by the unique attacker. That discovery triggered the emergency whitehat operation — the staff moved to drag all at-risk property earlier than one other actor might discover and exploit the identical second path independently.
The Protocol Behind The Incident
Flooring Protocol’s architect, @0xFreeLunch, acknowledged on X that the vulnerability originated in gas-saving bit-level code design — a category of optimization the place builders scale back computational prices by packing a number of values into shared storage slots. Despite a number of safety evaluations, the flaw went undetected, per his publish. The admission is notable: fuel optimization trade-offs that seem protected in isolation can create exploitable floor space when token IDs fall outdoors anticipated ranges.
Flooring Protocol had already been winding down its consumer-facing NFT providers since September 2025 — the platform suggested FPv2 token holders to redeem property and exit fractional positions earlier than October of that 12 months. Yet its good contracts remained dwell with person property inside, creating precisely the type of legacy publicity that attackers more and more goal in getting older DeFi infrastructure.
0xQuit warned on X that some NFTs stay underneath attacker management and urged all customers to keep away from depositing extra NFTs into Flooring Protocol till a verified repair is deployed. CryptoPunks — two of which have been among the many rescued property — at the moment carry a ground value of roughly 32.7 ETH, or roughly $54,612 per token, whereas BAYC NFTs sit round 9.16 ETH, per CoinGecko knowledge.
This improvement marks a pivotal and strange second for the nascent sector’s strategy to DeFi safety. A blue-chip NFT firm deploying its personal stability sheet to rescue third-party property from an energetic exploit — unprompted, at pace, and at price — is a type of ecosystem duty the area not often sees. The query the trade will now ask is what number of different getting older protocols nonetheless carry related vulnerabilities of their legacy contracts, ready for the attacker who finds the second path earlier than anybody else does.
