Atomic Wallet Hacked: Largest Victim Reportedly Lost 2.8M USDT
Some users blamed the wallet provider that they had funds stolen from their accounts in the past as well.
The non-custodial decentralized crypto wallet Atomic Wallet – with a reported user base of over five million customers – said some of its users complained about having their digital assets drained.
Later reports suggested that numerous users had six figures worth of crypto wiped out, while the largest victim lost nearly $3 million worth of Tether (USDT).
The team behind the wallet took it to Twitter yesterday to inform that some users complained about having their accounts compromised. Atomic said the team will go into further investigations, but there have been no official updates as of writing these lines.
The waves of complaints under the Atomic Twitter post continue, with some claiming that they had their funds stolen in the past and that the wallet provider did nothing to help them at the time.
Popular crypto sleuth – ZachXBT – said he received numerous messages from Atomic users regarding their lost funds.
According to the on-chain investigator, the largest single victim lost 2.8 million worth of Tether (USDT). ZachXBT added that they observed “multiple other losses” worth six figures in digital assets across different chains.
Although some reports claim that DeFi hacks are on the decline in contrast to rug pulls, there have been several larger ones in the past few weeks.
The latest example was the liquidity protocol Jimbos, which had $7.5 million worth of crypto drained last weekend.

Via #AnciliaAlerts on X, @rugged_dot_art has identified a re-entrancy #vulnerability in a smart contract with address 0x9733303117504c146a4e22261f2685ddb79780ef, allowing an attacker to #exploit it and gain 11 #ETH . The attack transaction can be traced on #Etherscan at https://etherscan.io/tx/0x5a63da39b5b83fccdd825fed0226f330f802e995b8e49e19fbdd246876c67e1f. Despite reaching out to the owner three days ago, there has been no response.
The vulnerability resides in the targetedPurchase() function, where a user can input arbitrary swapParams, including commands to 4. This triggers the UNIVERSAL_ROUTER.execute() function, and as per Uniswap Technical Reference, command 4 corresponds to SWEEP, invoking the sweep() function. This function sends ETH back to the user's contract, leading to a re-entrancy issue.
Within targetedPurchase(), a balance check is performed before and after calling _executeSwap(). Due to the re-entrancy problem, a user can stake tokens (e.g., from a flashloan) to satisfy the balance check, ensuring a successful purchase action where tokens are transferred to the user. The urgency of the situation is underscored by the ongoing waiting period for the owner's response, emphasizing the need for prompt attention to mitigate potential exploitation.

As announced, I would like to disclose the details of the exploit and how did we get the money back.
Firsly, the reason of the exploit was there was a bug in ‘request swap from #POTION to #BPET ’ functionality that makes the exploiter be able to withdraw excessive amounts of $BPET tokens from the PvP contract after staking their own tokens.
Below are some noticeable withdrawing transactions the exploiter made.
(https://arbiscan.io/tx/0x058b8808e721f68c01c62ad70687f38f39d749bfc9d0e8f6be839c3af603dec6)

Right after becoming fully aware of the exploit, we did 2 things
- Checked out to see if the exploiter’s addresses can be mapped with any Twitter profiles of any xPet users (and we found the user mapping with one of the exploiter addresses)
- Reached out to all partners in our network who can pour in the helps. They were explorer sites, centralized exchanges, privacy mixers, offramp tools, and security firms.
To be specific, #Etherscan team helped us to tag all 4 addresses related to the exploiter on Ethereum on Arbiscan as ‘xPet exploiter’. Thanks for that, the exploiter addresses were visibly exposed to and closely-watched by the public. All the centralized exchange, privacy mixer, and offramp tool teams helped to take close notice In case any of the exploiting address would have interactions with centralized exchange Hot wallets, privacy mixer contracts, or offramp tool depositing addresses. The security firms has helped us follow all, even smallest, onchain traces from the exploiter
In short, we had the combined efforts from multiple parties to closely monitoring the exploiter's movements and ensure that exploiter doesn’t have any chance to get the stolen funds mixed or obscured.

Explained Crypto Scams
In recent years, the crypto market has experienced exponential growth, attracting investors from all walks of life. However, alongside its meteoric rise, the industry has witnessed a surge in trading scams. These scams exploit the decentralized and unregulated nature of cryptocurrencies, leaving victims devastated and skeptical about participating in this promising market. This article sheds light on the various types of trading scams in the crypto world and provides crucial insights to help readers protect themselves from falling prey to such fraudulent activities.
Ponzi and Pyramid Schemes
One of the most prevalent trading #scams in the crypto sphere is the Ponzi scheme. In a typical Ponzi scheme, fraudsters promise high returns on investment (ROI) to attract unsuspecting victims. These scammers use funds from new investors to pay off previous investors, creating an illusion of profitability. Eventually, when new investors cease to join, the scheme collapses, and investors lose their funds.
Similarly, pyramid schemes operate by recruiting participants who invest a certain amount of money, with the promise of earning commissions from recruiting subsequent investors. As the pyramid grows, the scheme becomes unsustainable, resulting in financial losses for those at the bottom.
Pump and Dump Schemes
Pump and dump #schemes involve artificially inflating the price of a particular cryptocurrency through deceptive marketing techniques and false information. Fraudsters create hype around a low-value coin, luring investors to purchase it. Once the price reaches a desirable level, scammers quickly sell off their holdings, causing the price to plummet. This leaves investors who bought at the peak with substantial losses.
Fake Exchanges and Wallets
Scammers also #exploit the trust of #crypto enthusiasts by creating fake exchanges and wallets. They design websites and apps that resemble legitimate platforms, tricking users into depositing funds or sharing private information. Unsuspecting victims end up losing their assets or becoming victims of identity theft.
To protect against fake exchanges and wallets, it is vital to conduct thorough research, verify the platform's legitimacy, and only use trusted and well-established services. Additionally, enabling two-factor authentication (2FA) and storing cryptocurrencies in secure hardware wallets can significantly reduce the risk of falling victim to such scams.
Phishing Attacks
Phishing attacks are a common tactic employed by scammers to obtain sensitive information from unsuspecting crypto users. These scams involve sending deceptive emails, messages, or creating fraudulent websites that resemble legitimate platforms, tricking users into revealing their private keys or login credentials. With this information, scammers can gain unauthorized access to victims' crypto wallets and steal their funds.
To avoid falling victim to phishing attacks, it is crucial to exercise caution when clicking on links or downloading attachments from unknown sources. Double-checking the website's URL, ensuring it uses a secure connection (HTTPS), and using reputable anti-phishing tools can help mitigate the risk.
Initial Coin Offering (ICO) Frauds
Initial Coin Offerings (ICOs) provide startups with a means to raise funds by selling tokens to investors. However, this fundraising method has become a breeding ground for fraudsters. Scammers create fake #ICOs , promising revolutionary projects and substantial returns, only to disappear after collecting funds from unsuspecting investors. Conducting thorough due diligence, analyzing the team's credibility, and scrutinizing the project's whitepaper are crucial steps to avoid falling victim to ICO scams.
Conclusion
While cryptocurrencies present exciting investment opportunities, the prevalence of trading scams demands vigilance from investors. Understanding the various types of trading scams, being cautious while dealing with unknown platforms, and conducting thorough research before investing can go a long way in protecting oneself from falling prey to fraudsters.

Unraveling the Curve Finance : Exploit
Introduction
Decentralized Finance (DeFi) has emerged as a groundbreaking innovation, promising to revolutionize the traditional financial landscape. One of the most popular DeFi protocols, #CurveFinance , faced a significant challenge in recent times. Exploiting a critical reentrancy vulnerability, malicious actors managed to drain more than 47 million USD from the platform. This article aims to delve into the intricacies of the vulnerability, understand its implications, and explore the measures taken by the DeFi community to prevent such incidents in the future.
$CRV
Understanding #Curve Finance and its Pools
Curve Finance is a decentralized exchange protocol built on the Ethereum blockchain, specializing in stablecoin trading. It enables users to swap stablecoins with minimal slippage and low fees, making it highly appealing to DeFi enthusiasts. Curve achieves this by employing liquidity pools with an algorithm designed to maintain stable asset prices.
To ensure liquidity in these pools, users deposit their stablecoins in exchange for Curve's native token, #CRV . In return, they receive trading fees and incentives. This collaborative approach encourages participation and drives the platform's growth.
The Reentrancy Vulnerability Exploited
Reentrancy is a well-known and dangerous vulnerability in smart contracts. It allows an attacker to exploit a loophole in the code that permits repeated execution of a function before the previous invocation has completed. By exploiting this vulnerability, attackers can drain funds from the smart contract repeatedly, effectively bypassing intended restrictions.
The incident involving Curve Finance occurred when attackers found a way to exploit this reentrancy vulnerability in one of the platform's liquidity pools. By manipulating the flash loan feature, the attackers tricked the protocol into repeatedly withdrawing funds before updating the pool's balances. This enabled them to siphon off an extensive amount of funds in a short period.
Impact of the Attack
The consequences of the attack were severe, not only for Curve Finance but also for the broader DeFi ecosystem. The loss of over 24 million USD raised concerns about the security and robustness of DeFi protocols. Investors became wary, and confidence in decentralized financial platforms wavered.
Moreover, this incident highlighted the need for better security audits and comprehensive testing before deploying DeFi protocols in production. Security researchers and developers became more vigilant, intensifying their efforts to identify and resolve potential vulnerabilities in smart contracts.
Response from Curve Finance and the DeFi Community
In the aftermath of the attack, the Curve Finance team acted swiftly to contain the situation and prevent further losses. They initiated an emergency update and patched the vulnerability that allowed the reentrancy exploit. Additionally, they took steps to reimburse affected users who lost funds during the attack, demonstrating their commitment to maintaining trust within the community.
The incident also sparked discussions within the broader DeFi community about the need for better security standards.

Decentralized Finance (DeFi) has emerged as a groundbreaking innovation, promising to revolutionize the traditional financial landscape. One of the most popular DeFi protocols, #CurveFinance , faced a significant challenge in recent times. Exploiting a critical reentrancy vulnerability, malicious actors managed to drain more than 47 million USD from the platform. This article aims to delve into the intricacies of the vulnerability, understand its implications, and explore the measures taken by the DeFi community to prevent such incidents in the future.
$CRV
Understanding #Curve Finance and its Pools
Curve Finance is a decentralized exchange protocol built on the Ethereum blockchain, specializing in stablecoin trading. It enables users to swap stablecoins with minimal slippage and low fees, making it highly appealing to DeFi enthusiasts. Curve achieves this by employing liquidity pools with an algorithm designed to maintain stable asset prices.
To ensure liquidity in these pools, users deposit their stablecoins in exchange for Curve's native token, #CRV . In return, they receive trading fees and incentives. This collaborative approach encourages participation and drives the platform's growth.
The Reentrancy Vulnerability Exploited
Reentrancy is a well-known and dangerous vulnerability in smart contracts. It allows an attacker to exploit a loophole in the code that permits repeated execution of a function before the previous invocation has completed. By exploiting this vulnerability, attackers can drain funds from the smart contract repeatedly, effectively bypassing intended restrictions.
The incident involving Curve Finance occurred when attackers found a way to exploit this reentrancy vulnerability in one of the platform's liquidity pools. By manipulating the flash loan feature, the attackers tricked the protocol into repeatedly withdrawing funds before updating the pool's balances. This enabled them to siphon off an extensive amount of funds in a short period.
Impact of the Attack
The consequences of the attack were severe, not only for Curve Finance but also for the broader DeFi ecosystem. The loss of over 24 million USD raised concerns about the security and robustness of DeFi protocols. Investors became wary, and confidence in decentralized financial platforms wavered.
Moreover, this incident highlighted the need for better security audits and comprehensive testing before deploying DeFi protocols in production. Security researchers and developers became more vigilant, intensifying their efforts to identify and resolve potential vulnerabilities in smart contracts.
Response from Curve Finance and the DeFi Community
In the aftermath of the attack, the Curve Finance team acted swiftly to contain the situation and prevent further losses. They initiated an emergency update and patched the vulnerability that allowed the reentrancy exploit. Additionally, they took steps to reimburse affected users who lost funds during the attack, demonstrating their commitment to maintaining trust within the community.
The incident also sparked discussions within the broader DeFi community about the need for better security standards. Developers and auditors focused on enhancing their practices, conducting thorough code reviews, and implementing formal verification techniques to detect potential vulnerabilities early on.
Furthermore, the incident encouraged a collaborative approach among DeFi projects to share information about potential vulnerabilities and security best practices. This cooperation aimed to fortify the entire DeFi ecosystem against future exploits.
