Yuga Labs, the corporate behind Bored Ape Yacht Membership and CryptoPunks, accomplished a covert whitehat operation on June 8 to rescue 68 blue-chip NFTs — value greater than $500,000 — from an energetic exploit focusing on Flooring Protocol, deploying its personal funds and performing earlier than further attackers may drain property that included among the most respected tokens in NFT historical past.
Yuga Labs CEO Michael Figge (@mfigge) introduced the profitable operation on X, publishing a full stock of the rescued property now held within the firm’s custody: 29 Bored Ape Yacht Membership NFTs, 4 Mutant Apes, one Bored Ape Kennel Membership 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 via GrailsOTC, Yuga Labs’ over-the-counter buying and selling desk — which Figge stated he “quietly instructed” to entrance the capital and NFTs wanted to tug the at-risk property out of the protocol earlier than further unhealthy actors may act on the identical vulnerability. The corporate plans to return all 68 NFTs to their unique house owners as soon as a technical repair has been deployed and verified.
How The Crypto Exploit Labored
The mechanics of the assault, defined 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 information. 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 submit, got here from packed possession and indexing logic — a technical design selection the place a malicious token ID may make possession verification checks go whereas downstream accounting recorded a unique end result totally, creating what he described as “ghost possession.” An unchecked stability replace then prompted an arithmetic underflow, handing the attacker a stability far bigger than legitimately entitled. As soon as 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 further NFT swimming pools not but touched by the unique attacker. That discovery triggered the emergency whitehat operation — the staff moved to tug all at-risk property earlier than one other actor may 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. Regardless of a number of safety evaluations, the flaw went undetected, per his submit. The admission is notable: fuel optimization trade-offs that seem secure 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 companies since September 2025 — the platform suggested FPv2 token holders to redeem property and exit fractional positions earlier than October of that yr. But its good contracts remained dwell with consumer property inside, creating precisely the type of legacy publicity that attackers more and more goal in growing older DeFi infrastructure.
0xQuit warned on X that some NFTs stay underneath attacker management and urged all customers to keep away from depositing further NFTs into Flooring Protocol till a verified repair is deployed. CryptoPunks — two of which had been among the many rescued property — at present carry a ground worth of roughly 32.7 ETH, or roughly $54,612 per token, whereas BAYC NFTs sit round 9.16 ETH, per CoinGecko knowledge.
This growth marks a pivotal and strange second for the nascent sector’s method 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 value — is a type of ecosystem accountability the house hardly ever sees. The query the trade will now ask is what number of different growing older protocols nonetheless carry comparable vulnerabilities of their legacy contracts, ready for the attacker who finds the second path earlier than anybody else does.
