Clipper DEX suffers $450,000 hack

The Clipper decentralized exchange suffered a $450,000 exploit across two Ethereum layer-2 chains. Although some speculated that the issue may have been a private key leak, Clipper denied this, and instead said that an attacker had exploited a feature allowing people to make withdrawals denominated in a single token by performing swaps along with the withdrawal.

Although the $450,000 theft is relatively small compared to some other crypto hacks, it represented around 6% of the total value locked on Clipper. Clipper stated they were working to trace and attempt to recover funds, and asked the hacker to contact them to potentially negotiate a return of some funds.

Crypto exchange XT.com suffers $1.7 million hack

On November 28, cryptocurrency exchange XT.com abruptly suspended withdrawals, citing a "wallet upgrade and maintenance". However, after a blockchain security firm identified $1.7 million in suspicious transfers, XT.com acknowledged that they had "detected an abnormal transfer from our platform wallet". According to an announcement, the stolen funds were company assets, rather than cryptocurrencies belonging to users.

13-year-old rug pulls crypto token, then faces retaliation

A 13-year-old known as the "Gen Z Quant kid," created a token called QUANT and executed a rug pull, making $30,000. In retaliation, various people in the cryptocurrency world executed a "revenge pump" — pumping up the price of the token after the kid cashed out, causing him to miss out on potential gains. Worse, they then found the child's identity, and published his address and the school he attended. They also identified his mother, and began leaving hateful comments on her Instagram account. Rumors also emerged that a member of the cryptocurrency community dognapped the child's dog, then launched a memecoin based on the animal.

Around $21 million in losses reported by users of DEXX

DEXX, a platform that advertises itself as the "first memecoins trading terminal application", disclosed that it had been hacked when it posted a message on social media addressed to "Mr./Ms. Hacker", asking they return stolen funds in exchange for "destroy[ing] all information we currently have on the hack" and not pursuing further legal action.

DEXX did not disclose how much was taken in the breach, but hundreds of victims have reported around $21 million in combined losses so far.

Polter Finance exploited for $12 million

The Fantom-based Polter Finance defi project was exploited for $7 million when an attacker was able to perform an oracle manipulation attack. By artificially increasing the price of the $BOO token, which is a governance token used by the SpookySwap project, they were then able to use that token to drain Polter's liquidity pools using a flash loan. The attacker successfully drained the entire $12 million worth of tokens on the platform.

The creator of the platform stated that they had filed a police report with Singaporean authorities. They also attempted to contact the hacker via on-chain message to negotiate the return of funds, but have not received a response.

Thala Labs loses, then recovers, $25.5 million

The Thala Labs Aptos-based defi project suffered a $25.5 million theft when an attacker exploited a vulnerability in one of their smart contracts. They paused related smart contracts and froze tokens where they were able, ultimately freezing around $11.5 million in assets. After working with law enforcement and several blockchain security teams, they successfully negotiated the return of the assets, leaving the attacker with a "bounty" of $300,000.

DeltaPrime loses $4.8 million in second hack

The DeltaPrime defi protocol was hacked for the second time in two months, losing $4.8 million in Arbitrum and Avalanche tokens. The attacker appeared to have exploited a flaw in one of the platform's smart contracts that enabled them to borrow more than they put up in collateral.

DeltaPrime paused the protocol on both Arbitrum and Avalanche, stopping the attacker from being able to steal more funds than they already had.

DeltaPrime was hacked previously on September 16, losing $6 million after a leaked private key enabled an attacker to mint a huge number of the platform's stablecoin deposit receipts.

Trader reveals he lost $28 million to bad copy-paste

After apparently exhausting all his other options, a trader has put out a call to "all skilled hackers and white hats out there" to help him recover 7,912 Renzo staked ETH (ezETH) he inadvertently sent to an inaccessible address back in June. The tokens were priced at a little over $28 million at the time, and are currently priced at a little less than $26 million. According to the trader, he copied the wrong address to his clipboard before making the trade, which rendered his funds permanently inaccessible.

Short of finding a vulnerability in Renzo, the trader's only real choice is to plead with Renzo to change their smart contract in such a way as to release the funds. While this is technically possible, Renzo has told the trader they could not grant his request due to "regulatory limitations".

CoinPoker exploited for $2 million

Crypto-powered poker website CoinPoker was apparently exploited for around $2 million when an attacker was able to compromise a hot wallet controlled by the platform. The attacker then laundered most of the funds through the Tornado Cash mixer.

The platform sent a message to the exploiter attempting to negotiate a return of some of the funds.

MetaWin casino hacked for $4 million

Hot wallets used by the MetaWin crypto casino were drained of around $4 million. According to the company's CEO, the attacker "t[ook] advantage of our frictionless withdrawal system". The attacker then moved the stolen funds to crypto exchanges including KuCoin.

Supply chain attack stemming from JavaScript animation library results in losses for users of 1inch and other platforms

Attackers were able to inject malicious code into the popular "LottieFiles" JavaScript animations library. Visitors to websites using the library saw a prompt to connect their crypto wallets to what was ultimately a cryptocurrency wallet drainer. This affected some crypto platforms that used the library, including the 1inch decentralized exchange aggregator. One victim who connected their wallet suffered the loss of 10 BTC (~$723,000).

Other crypto platforms affected included TEN Finance and Movement. Because the animations library is widely used, other non-crypto-related websites also showed the prompt.

M2 cryptocurrency exchange hacked for $13.7 million

The UAE-based M2 cryptocurrency exchange was hacked for $13.7 million in bitcoin, ether, and Solana tokens. The exploiter compromised several of the exchange's hot wallets to take the funds.

Shortly after the theft, M2 acknowledged the hack and announced that "the situation has been fully resolved". This apparently involved M2 restoring customer funds from their own assets, rather than recovering the stolen assets.

Sunray Finance hacked for $2.7 million

A perpetuals trading platform called Sunray Finance was hacked on October 30 by an attacker who was able to upgrade a smart contract used by the protocol. They then were able to mint a massive number of the protocol's SUN token — 200 sextillion, to be precise. Then, they cashed out what they were able to, crashing the SUN token price in the process. Ultimately, the attacker made off with about $2.1 million of the Tether stablecoin.

In the process of selling off tokens, an arbitrage bot was able to take advantage of the price difference by selling the rapidly crashing SUN token into a second liquidity pool that apparently went unnoticed by the hacker, and the bot operator also profited around $560,000.

$20 million moved from US government wallet in possible theft

More than $20 million in stablecoins and Ethereum were transferred from a wallet identified as belonging to the US government, and holding funds connected to the 2016 hack of the Bitfinex cryptocurrency exchange. While the government does occasionally shuffle cryptocurrency around, these funds were moved to a brand new wallet and then began to be shuffled through cryptocurrency exchanges — something that crypto sleuth zachxbt noted "looks nefarious".

The government has not made any statements regarding the movement of assets.

The following day, $19.3 million in tokens were returned to the original wallet.

Sharpei memecoin rug pulls for $3.4 million

A dog-themed memecoin project called Sharpei abruptly cashed out $3.4 million, tanking the token price by more than 96% in seconds. The project had been promoted by crypto influencers, but hit a snag when a pitch deck for the project leaked. The deck contained multiple lies, including claims to have hired multiple "KOLs" who later denied involvement, and false claims of partnerships with various platforms and projects.

As the token price stuttered along with these revelations, insiders apparently decided to quit while they were ahead, and cashed out in a quick and coordinated sale.

Blockchain company Forte acquires games studios, demands secrecy, shuts them down

Sometime in 2023, blockchain firm Forte acquired game studios Phoenix Labs and Rumble Games. However, it would be a year before this came to light, because according to a report from Game Developer, Forte demanded secrecy from employees. (Forte refutes this). In both cases, some employees believed that Forte was funding their development, but didn't find out until later that Forte owned the companies.

Both studios had several games in progress, and two of Phoenix Labs' games were explicitly designed for younger players. Developers reportedly voiced discomfort with incorporating blockchains into the games, selling digital items to children.

Later, Forte pulled the plug on several in-development games at both studios. Then, Forte shut down Rumble in 2024, laying off all employees. Forte also laid off over 100 people from Phoenix Labs that year.

Tapioca DAO exploited for most of its assets — over $4 million

The defi lending protocol Tapioca DAO was exploited after an attacker reportedly socially engineered the DAO's co-founder and gain access to their private key. The attacker then used their access to sell off TAP tokens, and to drain a stablecoin liquidity pool on the platform, netting around $4.4 million in USDC and ETH. The TAP token price subsequently crashed by around 96%.

Various security researchers have observed that the attack appears to be linked to a slew of social engineering attacks perpetrated by cybercriminals out of North Korea.

Radiant Capital exploited again, this time for at least $50 million

The cryptocurrency lending project Radiant Capital was hacked for the second time in under a year, this time for more than $50 million in the USDC stablecoin, wBNB, ETH, and other tokens. An attacker successfully gained access to three of eleven private keys controlling a multisignature wallet, which enabled them to upgrade the project's smart contracts in such a way as to drain funds.

This is the second Radiant Capital exploit this year, after a $4.5 million theft in January that was enabled by an unaddressed vulnerability in the underlying Compound Finance code.

Cosmos founder reveals a portion of the protocol was created by North Korean developers

Cosmos creator Jae Kwon has raised concerns about a portion of the Cosmos protocol called the "Liquid Staking Module" after learning it was developed by North Korean agents. Although a contributor to the protocol, Zaki Manian, learned of the developers' links to North Korea after contact from the FBI in March 2023, Kwon claims that Manian ignored known flaws in their code, failed to fully audit their code, and did not report the issue to the project team or the Cosmos community. According to Kwon, the code contained a vulnerability that would allow stakers to avoid having their stakes slashed, which "contradicts the fundamental principles of staking security."

Kwon urged the Cosmos governance team to perform a full audit of the code written by these developers, and develop more protocols to prevent issues like this going forward. He also called for the governance team to blacklist Zaki Manian.

Permit phisher steals almost $1.4 million in frog tokens

An attacker using the permit phishing technique stole $1.39 million in tokens from an unsuspecting holder. The victim unknowingly signed a "Permit2" signature — a function intended to make crypto transactions smoother and less expensive, but one that also makes it possible for malicious actors to completely drain crypto wallets.

The attacker stole around $1.1 million of the cartoon frog-themed PEPE tokens, and another roughly $50,000 of the also cartoon frog-themed APU token.

$3.1 million in EIGEN tokens stolen and sold

Around 1.67 million EIGEN tokens belonging to an investor in the popular Ethereum-based EigenLayer project were stolen after the investor was tricked into transferring the tokens into the attacker's wallet. The thief then sold the tokens for around $3.1 million, although the tokens were notionally worth around $5.5 million. Some of the stolen funds were later frozen by centralized exchanges.

After the incident, some questioned why the tokens had been sent to an investor without a vesting contract, given they were supposed to be locked for a period of time to prevent sale.

Victim loses over $32 million to wallet drainer

A victim lost 12,083 spWETH tokens (~$32.4 million) after signing a malicious transaction stemming from someone using wallet drainer software. These drainers are "scam-as-a-service" products, where the drainer creators allow others to operate the drainer software in exchange for a 20% cut of stolen funds.

The victim wallet sent a message to the thief, offering "a peaceful resolution to this situation" in which the thief could keep 20% of the total amount taken (around $6.5 million).

Bedrock staking platform loses $2 million after bug that allowed users to trade Bitcoin and Ethereum 1:1

A staking platform called Bedrock lost around $2 million after exploiters discovered a bug that allowed them to swap 1 ETH for 1 BTC despite the more than $63,000 difference in prices for the two assets.

A security firm working with Bedrock had tried to warn Bedrock of the vulnerability several hours before the attack, but the team was asleep. The vulnerable contracts had been deployed a day and a half prior to the attack, and had not been audited.

Fortunately for Bedrock, security groups were able to pause third-party projects surrounding Bedrock, which helped to limit the losses — which ultimately could have been as high as the entire value of funds on the protocol.

Onyx hacked for $3.8 million via the same exploit used against them less than a year ago

The Onyx protocol was hacked for a second time by attackers taking advantage of known bugs in forks of the Compound Finance project. Projects regularly fail to patch these bugs, despite many instances of multi-million dollar hacks affecting Compound forks in the past.

Onyx apparently didn't learn their lesson the first time around, when they were exploited for $2 million in November 2023 by an attacker taking advantage of a known vulnerability affecting empty markets on the protocol. This same bug seems to have contributed to this exploit, although Onyx has claimed the hack was due to a separate vulnerability in an NFT liquidation contract.

Truflation hacked for around $5 million

The Truflation platform suffered a loss of around $5 million after what they described as "an attack using malware". The company acknowledged the attack and limited some of their services while they worked to mitigate it. They also offered a reward to "any white hats offering assistance", and offered to negotiate a "bug bounty" with the attacker.

Truflation is a blockchain-based project that provides economic data including inflation rates and asset valuations. The platform has been backed by Coinbase Ventures, Chainlink, and others.

OpenAI Twitter account once again hacked and used to promote scam token

The Twitter account belonging to OpenAI's news account was compromised and used to "announce" a scam website purporting to announce the $OPENAI token. "All OpenAI users are eligible to claim a piece of $OPENAI’s initial supply. Holding $OPENAI will grant access to all of our future beta programs," the scam tweets claimed. A link in the tweets directed users to a malicious website that invited users to connect their wallets to claim tokens.

This latest hack is only the latest in a slew of Twitter account compromises "announcing" a scam token. Over a year, OpenAI CTO Mira Murati had her account hacked to promote an "$OPENAI" token. Three months ago, accounts belonging to chief scientist Jakub Pachocki and researcher Jason Wei were hacked and used to post the same scam as today.

Shezmu hacked for almost $5 million, negotiates bounty

A crypto yield platform called Shezmu suffered a loss of around $4.9 million in $ShezUSD after an attacker exploited a flaw that allowed anyone to mint collateral, which they could then use to borrow ShezUSD. These tokens were relatively illiquid, however, so the total amount the attacker could have obtained was likely considerably less.

Shortly after the attack, Shezmu offered a 10% "bounty" for the return of the funds. The attacker responded that they would only consider a 20% bounty. Shezmu agreed to the terms, and announced to their followers that they had achieved a recovery from the "white hat" hacker.

BingX hacked for $52 million

Singaporean cryptocurrency exchange BingX suffered a $52 million loss across a broad range of cryptocurrencies. The thefts occurred across two attacks that were hours apart. The attack appears to have targeted one of the exchange's hot wallets.

Some accused the exchange of trying to cover up the theft by announcing "temporary wallet maintenance" without disclosing that a theft had occurred. The team later announced that "there has been minor asset loss", and stated that the lost funds would be restored out of the company's capital.

Around $10 million of the stolen assets were frozen during recovery efforts after the theft.

Germany seizes 47 cryptocurrency exchanges reportedly used by ransomware groups

Webpage announcing seized crypto exchange. Letter reads: "Operation Final Exchange THIS WAS YOUR FINAL EXCHANGE! This is for you, ransomware affiliates, botnet operators and darknet vendors: For years, the operators of these criminal exchange services have led you to believe that their hosting cannot be found, that they do not store any customer data and that all data is deleted immediately after the transaction. An apparently unregulated hub allowing you to launder the proceeds of your criminal activities without fear of prosecution. From our point of view: nothing but empty promises! We have found their servers and seized them - development servers, production servers, backup servers. We have their data and therefore we have your data. Transactions, registration data, IP addresses. Our search for traces begins. See you soon."Warning on seized domains (attribution)
German authorities have seized 47 cryptocurrency exchanges alleged to have been used to launder stolen funds by ransomware groups. The exchanges did not require KYC, allowing customers to remain anonymous throughout their transactions.

Websites for these exchanges now show notices announcing a law enforcement operation called "Operation Final Exchange". The page announces to visitors "This was your final exchange!", and in a letter addressed to "ransomware affiliates, botnet operators and darknet vendors", warns that authorities are now working to trace the illicit users of the exchange.

Almost $2 million taken from users of Telegram "Banana Gun" crypto trading bot

Some people use a Telegram-based crypto trading bot called "Banana Gun" to "snipe" crypto trades, copytrade, and perform other activities. On September 19, at least 11 victims lost around $3 million after their accounts were apparently compromised and drained.

Banana Gun acknowledged the attack on Twitter and shut down the bot. They posted that they did not believe their backend was compromised, and stated that they believed the attack occurred via a "front-end vulnerability" — though it was not clear what this might have referred to.

Arrests made after $243 million stolen from one individual in Gemini phishing attack

Two people have been arrested in relation to a phishing scam that successfully stole more than 4,000 BTC priced at around $243 million from a single individual. The victim was targeted with a phishing scam in which the attackers posed as Google support employees and convinced the victim to reset their two-factor authentication for their account on the Gemini cryptocurrency exchange.

The FBI raided a luxury home in Miami in connection to the theft, and arrested two men in their early twenties. Authorities worked with crypto investigators including zachxbt to trace the stolen funds.
