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".

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.

Rari Capital settles with the SEC

The defi lending protocol Rari Capital, and its three co-founders, have settled charges from the SEC that it misled investors and engaged in unregistered broker activity. Rari Capital entities also settled charges that they conducted unregistered offerings of three securities, and engaged in unregistered securities offerings and unregistered broker activity. The SEC alleged that the firm and its co-founders made false statements to investors about supposedly automatic re-balancing of assets into the highest yield opportunities when, in fact, rebalancing was also done manually. The SEC also alleged that the company and its co-founders made misleading statements about the supposedly high yield from the platform, which they said did not account for fees, and which ultimately caused many investors to lose money.

The company and co-founders will pay fines, and the individuals will agree to five-year bans from serving as officers or directors.

The regional SEC director stated, "We will not be deterred by someone labeling a product as 'decentralized' and 'autonomous'," alluding to crypto firms' tendencies to try to skirt securities regulations by claiming to be "decentralized".

Rari has featured on Web3 is Going Just Great before, when they were exploited for around $80 million in April 2022 and when they were exploited for around $15 million in May 2021. The project effectively wound down soon after the second theft.

Ethena website compromised

The website for the Ethena protocol was compromised by attackers who gained control of the project's domain registration. The protocol issued warnings to their users to urge them not to interact with the website, which could compromise their crypto holdings.

They later were able to deactivate the website and regain control of the domain. "Remember scammers are always chasing you," they wrote on Twitter.

$6 million taken from Delta Prime defi protocol

The DeltaPrime defi protocol suffered a $6 million loss after a private key was leaked. Access to the private key allowed the attacker to mint 1.1×1069 DPUSDC, which are tokens that allow holders to redeem the USDC stablecoin at a 1:1 ratio. They repeated the mint with several other deposit receipt tokens for bitcoin, ether, and other cryptocurrencies. Altogether, they redeemed a small fraction of these enormous quantities of deposit receipts, amounting to around $6 million in assets.

DeltaPrime acknowledged the attack on Twitter, and announced that "the risk is contained". They also stated that they were "looking into other ways to reduce user losses to a minimum", including by pulling from the protocol's insurance pool.

Flappy Bird creator disavows crypto spin-off

Tweet by @flappy_bird: "I AM BACK!! 

Just a decade ago, I was the talk of the town and soaring to new heights with my 100 million friends. Sadly, I had to leave the fame and spotlight behind to go home and find out who I really am.

Thanks to my super Flappy Bird® fans, I’m refreshed, reinvigorated, and ready to soar again. The decade-long mission involved acquiring legal rights and even working with my predecessor to uncage me and re-hatch the official Flappy Bird® game!" A community note adds: "The new Flappy Bird is not made by the original creator Dong Nguyen.
Gametech Holdings has acquired the trademark for Flappy Bird."Tweet by @flappy_bird (attribution)
A blockchain-based version of the 2014 hit game Flappy Bird has emerged, taking advantage of the recent "tap-to-earn" crypto craze. The @flappy_bird Twitter account posted "I AM BACK!!" on September 12, with a video compilation showing people playing the original game. The tweet also claimed they were "working with [Flappy Bird's] predecessor", leading many to believe that the original Flappy Bird creator Dong Nguyen was involved with the project.

Nguyen famously removed the game from app stores shortly after it surged to popularity, stating that he felt guilty that people were becoming addicted to the game. This makes the game's reappearance — complete with loot boxes and other addictive features — feel somewhat dark.

On September 15, Nguyen returned from a seven-year Twitter hiatus to post: "No, I have no related with their game. I did not sell anything. I also don't support crypto."

Although Nguyen held the Flappy Bird trademark, he did not sell it to this group. Instead, they registered the trademark themselves after arguing he had abandoned it.

Eve Online developer angers fans with announcement that their new game will be blockchain-based

"Always Has Been" meme. The world is titled "Eve Frontier", the front astronaut is titled "cryptobros" and the astronaut with the gun is titled "Eve veterans". The text reads "It's all an unprofitable hellscape?"r/Eve meme (attribution)
CCP, the developer of the Eve Online space MMORPG, has angered their fanbase with a new announcement that their upcoming game will be built on the blockchain and incorporate cryptocurrency for in-game transactions. According to an FAQ, the spin-off game (previously called "Project Awakening" and now titled "Eve Frontier") will use a layer-2 blockchain called Redstone.

"There is still time. You can still roll it back and pretend it never happened. Please. None of us want this crypto slop, this desperate cash grab, this attempt at 'creating something great,' this game where buzzwords seem more important than gameplay," wrote one player on the game's subreddit.

A tweet announcing the game was celebrated by some crypto advocates, but attracted some critical responses from players. One wrote, "releasing a blockchain game a year after the weird hype about that technology died so now you got a shitty concept and don't even get a pay-off for it. let's see how this is going to turn out :)"

eToro settles with SEC for $1.5 million, shuts down most crypto trading

The eToro stock and crypto trading platform settled with the U.S. Securities and Exchange Commission on charges that it was operating an unregistered broker and unregistered clearing agency, and facilitating trading certain crypto assets as securities. The platform agreed to pay $1.5 million in fines. As a part of the settlement, the platform will also restrict crypto trading for its U.S.-based customers to only bitcoin, bitcoin cash, and ether.

Adam Neumann's Flowcarbon refunds customers after failing to launch "Goddess Nature Token"

In May 2022, WeWork founder and former CEO Adam Neumann announced he would be launching a company called Flowcarbon, which would issue "tokenized carbon credits" called "Goddess Nature Tokens" and sell them to companies looking to green up their image. The company raised $70 million in funding from Andreessen Horowitz and others, at least half of which was raised through token sales.

Now, Flowcarbon has reportedly been issuing refunds after the tokens have failed to materialize more than two years later. Flowcarbon has reportedly been blaming "market conditions and resistance from carbon registries" for the failure to launch, according to a report from Forbes. Flowcarbon claimed they have been offering refunds "due to industry delays" since 2023.

CryptoPunk sells for a fraction of its likely market price due to zombie smart contract

A CryptoPunk resembling an ape, wearing a blue and white sweatband and small sunglassesCryptoPunk #2386 (attribution)
A rare CryptoPunk NFT recently sold for only 10 ETH (~$25,300), despite a market value that's likely around 600 ETH (~$1.5 million). The sale went through thanks to lingering smart contracts from a defunct NFT fractionalization platform called Niftex, which allowed people to buy and sell "shards" of various NFTs. Niftex launched in November 2020, and is now defunct, with its domain redirecting to the Kraken cryptocurrency exchange.

The platform's smart contracts remain operational, however, and so despite the lack of a frontend website for the platform, the backend still remains. A trader was able to use these smart contracts to trigger a feature that allows a buyout of the fractional shard holders which, if not countered by someone else, automatically goes through in 14 days. The bidder proposed a purchase of 0.001 ETH per share, and without an operational Niftex frontend, no one noticed. The bid went through, and the trader successfully purchased all 10,000 shares — and thus, the NFT — for 10 ETH.

Since then, several people have offered to purchase the NFT for amounts ranging from 100 to 605 ETH. If the new owner were to accept the 605 ETH bid, they would 60x their purchase price.

One owner of a fractionalized share said he thought he had managed to successfully block the sale, but miscalculated. "GG to the new owner", he wrote. He wrote on Twitter, "I don’t consider this a heist. It’s an arb. The smart contract worked as intended. If you want decentralized systems you have to take the good with the bad. It’s part of the game. It’s why we’re here. If you don’t like those rules, you probably shouldn’t be playing."

Hacker steals $1.45 million from CUT token liquidity pool

An attacker exploited a bug in the smart contract for a BSC-based token called CUT, draining a PancakeSwap liquidity pool of almost $1.45 million in the BSC-USD stablecoin.

Indodax crypto exchange apparently hacked for at least $22 million

The Indonesian Indodax cryptocurrency exchange suffered an exploit that allowed attackers to steal tokens from several of its hot wallets. The firm did not directly acknowledge the theft, instead posting an announcement that they had "discovered a potential security issue" and were "conducting a complete maintenance to ensure the entire system is operating properly". They reassured customers that their assets were "100% safe".

Indodax's Instagram account also appeared to be compromised, promoting a suspicious "giveaway".

State securities regulators settle with GS Partners over pyramid schemes including "tokenized skyscraper"

Rendering of a skyscraper in Dubai, with the Burj Khalifa in the backgroundRendering of the supposed "G999 Tower" (attribution)
Five states have settled with the European crypto firm GS Partners over several crypto investment pyramid schemes. These included one in which the firm sold crypto "vouchers", each representing a single square inch of a 36-floor Dubai sksycraper, which they said would allow holders to earn passive income from rental leases. The group reportedly offered a 5% weekly guaranteed return. Other schemes involved selling metaverse land and a token purportedly backed by gold. GS Partners worked with various celebrity spokespeople, including eternal moth-to-the-flame of scammy crypto projects, Floyd Mayweather. The GS Partners firm shut down in the United States as of December 2023.

Terms of the settlement include 100% repayment of investments made by victims in the five states that settled: Texas, Alabama, Arizona, Arkansas, and Georgia.

GS Partners has also faced regulatory scrutiny in other US states, as well as in Canada, Australia, and South Africa.
