Resupply announced the theft shortly afterwards, and stated that they had paused the vulnerable contract.
Resupply is a fairly new project, having officially launched on March 20 — about three months before the exploit.
Resupply stablecoin lender exploited for $9.3 million
An attacker was able to exploit a vulnerability in a smart contract used by the Resupply stablecoin lender to extract about $9.3 million from the project. After depositing around $200,000, they were able to inflate the price of another token and borrow almost $10 million.
Self Chain fires founder after $50 million scam allegations
On June 19, a company called Aza Ventures published allegations on Telegram that they had been scammed by someone promising to facilitate OTC sales of steeply discounted tokens for projects like SUI and NEAR. They claimed they had discovered the whole scheme was a Ponzi.
Aza Ventures was initially hesitant to name the scammer, hoping they could pressure the scammer to return the stolen funds, but later reports quickly named Self Chain founder Ravindra Kumar as the alleged culprit. Kumar posted on June 19, "I've been accused of serious wrongdoing, which is completely false."
On June 23, Self Chain announced that they had terminated Kumar as CEO "due to recent developments that diverge from the founding vision".
New York scammer "daytwo" steals $4 million from Coinbase users, blows most of it gambling
Christian Nieves, a New York man who goes by the handles "daytwo" and "PawsOnHips", has reportedly stolen more than $4 million through a theft ring where he impersonates Coinbase customer support. An investigation by crypto sleuth zachxbt outlined thefts from multiple Coinbase users, including one elderly victim who lost $240,000.
zachxbt noted that Nieves seems to have a gambling problem, depositing much of the stolen funds into crypto gambling websites. "You’ll see onchain how casino deposits get smaller as he loses funds," wrote zachxbt. "Recently this escalated to the point where he started stealing cuts from accomplices." He also appears to have used some of the stolen funds on luxury goods, including a Corvette and expensive watches.

Hacken token crashes after private key leak
Web3 cybersecurity firm Hacken had a cybersecurity incident of their own when the private key belonging to a wallet with mint access for the project's $HAI token was leaked. According to Hacken, the leak was attributable to "human error during architectural changes". After a malicious party gained access to the key, they minted around 900 million $HAI on the Ethereum and BNB chains, almost doubling the total supply. The attacker only profited around $250,000, but they crashed the token price by around 97% in the process.
Israeli-linked hackers steal and destroy $90 million from Iranian Nobitex exchange
The Iran-based Nobitex cryptocurrency exchange suffered a $90 million hack, and the attacker has also promised to imminently release data and source code from the platform. The hacking group appears to have burned the crypto assets, effectively destroying them rather than taking them for their own profits.
Gonjeshke Darande (also "Predatory Sparrow"), a hacking group with links to Israel, claimed responsibility for the theft, accusing the platform of serving as a "key regime tool" to finance terror and violate sanctions. The cyberattack comes shortly after Israel launched air strikes on Iran.
Meta Pool exploited
An attacker exploited a vulnerability in the staking contract for Meta Pool, which is a liquid staking project. This allowed them to mint 9,700 mpETH, the project's liquid staking token, which is notionally worth $27 million. However, very low liquidity for the token meant that the attacker was only able to swap 10 ETH (~$25,000) of tokens.
Meta Pool acknowledged the theft in a post shortly after the exploit was noticed by a blockchain security firm, and announced that the team had paused the project's smart contract.
ALEX Lab exploited again
ALEX Lab lost $8.3 million in various currencies after an attacker exploited a flaw in the project's smart contracts that allowed them to create a malicious token. They drained a number of pools on the protocol, amounting to around $8.3 million.
ALEX announced they would reimburse stolen user funds.
This is the second exploit affecting ALEX Labs, after a thief stole around $2 million in May 2024.
Crypto exchange BitoPro belatedly discloses $11.5 million hack
The Taiwanese cryptocurrency exchange BitoPro disclosed that they had suffered a theft from one of their hot wallets, which they said occurred during a system upgrade in which they were transferring assets between wallets.
The theft was originally noticed by crypto sleuth zachxbt, who observed a suspicious transfer of around $11.5 million in crypto assets on May 8. The funds sold on decentralized exchanges and then laundered through various cryptocurrency mixing services.
BitoPro originally only told customers that the platform was offline for "maintenance", but disclosed the theft on June 2 after zachxbt published his findings.

Cork Protocol exploited for $12 million
Cork Protocol, a defi project aimed at "tokenizing the risk of depeg events for stablecoins and liquid (re)staking tokens", suffered a $12 million loss after an attacker exploited a bug in how the project's smart contract calculated exchange rates. The attacker stole around 3,762 wrapped staked ETH (wstETH), which they exchanged for ETH. The project announced that they were investigating the theft and had paused markets.
Cork had been audited in whole or in part by four different security firms. The project's funders include Andreessen Horowitz, OrangeDAO, and Steakhouse Financial, and Cork is a part of Andreessen Horowitz's Crypto Startup Accelerator.
Cetus DEX exploited for $223 million; some funds "paused"
An attacker stole $223 million from the Sui-based Cetus Protocol. The project announced shortly after that $163 million of the funds had been frozen, leaving around $60 million unaccounted for.
This led some to question how decentralized the project truly is if the funds can be frozen in such a way.
Sui validators later voted to return the frozen assets to the Cetus project. Cetus also announced that users would be fully compensated, and that they would cover the $60 million gap with project treasury funds and a loan from the Sui Foundation.
Curve Finance website and Twitter account hacked
The website and Twitter accounts belonging to the Curve Finance defi projects were compromised in quick succession. On May 5, an attacker compromised the Twitter account belonging to the project, posting a scam in which they appeared to announce an airdrop.
Then, on May 12, the project posted a warning that the website for the Curve frontend was "hijacked" in an apparent domain takeover.
This is not the first such compromise for Curve, which suffered a frontend compromise in August 2022 that resulted in $620,000 in losses (later recovered with the help of some exchanges).
Founder of Zerebro token fakes his death, promotes new "legacy" coin
On May 4, 22-year-old Zerebro founder Jeffy Yu published a blog post introducing "legacoins" — a version of memecoins he said would be used to "define the legacy" of those who had died. Several days later, Yu's Twitter account announced that a "deadman's switch" had triggered the launch of his own "legacoin", $LLJEEFFY. Elsewhere, a video appeared to record Yu's suicide, and an obituary describing him as a "martyr of imagination and creativity" appeared on Legacy.com.
It wasn't long, however, before people began to speculate that Yu had faked his death. Wonderland CEO Daniele Sestagalli published a letter he said he had privately received from Yu, where he confessed to faking his death and described it as his "only viable exit from persistent harassment, blackmail, and threats". Others noted that wallets belonging to Yu had been cashing out $ZEREBRO tokens priced at around $1.3 million.
Reporters from the San Francisco Standard ultimately located Yu at his parents' house, where he was "agitated and shocked that he had been found after some routine internet searches", and "declined to talk about the false report of his death or how he may have benefited financially from it."

Bitget accuses "professional arbitrage" group of profiting $20 million from VOXEL market manipulation
After trading — and prices — surged in Bitget's market for the thinly traded video game token VOXEL, the company has accused a "professional arbitrage" group of "improperly" profiting $20 million from manipulating the market. A Bitget executive stated on Twitter that they had issued legal demands to eight accounts they said were responsible for "instigating" the unusual trading activity.
$330 million in Bitcoin apparently stolen; laundering spikes Monero price by over 40%
3,250 BTC (~$330 million) were apparently stolen from a bitcoin holder and then quickly moved through multiple exchanges and swapped for the Monero privacycoin. Such a massive swap into Monero was apparently enough to cause the Monero price to spike from around $230 to as high as around $330, before retracting somewhat.
Term Finance loses $1.65 million due to misconfiguration, recovers $1 million
The Ethereum-based lending project Term Finance lost $1.6 million when an oracle misconfiguration resulted in unintended liquidations. The team later announced that they had "successfully negotiated [the] return" of 333 ETH (~$600,000) that had been lost, and that another roughly 223 ETH (~$400,000) had been "captured internally", leaving the final loss at around 362 ETH (~$650,000).
Loopscale hacked for $5.8 million two weeks after launch
A new Solana-based defi protocol called Loopscale, backed by Coinbase Ventures and Solana Labs, suffered a $5.8 million exploit only two weeks after its launch. The stolen funds represented 12% of the protocol's TVL. The project blamed the exploit on a bug in the protocol's pricing calculations. Although the project had been audited in February by OShield, the audit evidently did not detect the flaw.
$5 million in tokens stolen from ZKsync
An attacker compromised an admin account belonging to the ZKsync Ethereum layer-2 project, which is built by Matter Labs. By doing so, they were able to steal approximately $5 million worth of the ZK token, which the project said were "the remaining unclaimed tokens from the ZKsync airdrop".
ZK Sync offered a 10% "bug bounty" to the thief, who accepted and returned 90% of the stolen funds.
