😈On Oct 6, 2022, the $RES Token on the Binance Smart Chain suffered a flash loan attack, leading to a theft of roughly $290,000.
The attacker exploited a vulnerability in the token’s #smartcontract, manipulated the pool price, and profited by swapping #tokens.
😈On Oct 11, 2023, a major exploit hit the $BH token on the #BSC chain when due to a suspected price manipulation, it lost💰~$1.27 million.
- Attacker Address: 0xFDbfcEEa1de360364084a6F37C9cdb7AaeA63464
- Contract Address: 0xCC61CC9F2632314c9d452acA79104DDf680952b5
The attacker executed a complex series of transactions to carry out this exploit. It all started with a flash loan involving a significant amount of $USDT.
From there, the attacker made use of smart contracts and specific functions to manipulate the price of $BH and extract profits.
- Flash Loan: The attacker initiated a flash loan to obtain a substantial amount of $USDT.
- Liquidity Addition: Next, the attacker called the 0x33688938() function to add $USDT to the contract.
This action added liquidity to the trading pair, with the standard liquidity ratios being approximately 1 USDT: 100 BH.
- Token Swap: Subsequently, the attacker swapped $USDT for $BH through the trading pair.
- Liquidity Removal: To maximize their gains, the attacker invoked the 0x4e290832 function to remove liquidity from the pair.
Due to the attacker’s well-timed swap, the liquidity removal ratio was significantly altered, resulting in approximately 1 USDT: 2 BH.
This discrepancy allowed the attacker to withdraw more $USDT than they initially provided, thereby profiting from the price manipulation.
The Stolen Funds have been sent into Tornado Cash.
😈On Oct 11, 2022, the crypto ecosystem witnessed one of its darkest days, when a series of hacks and exploits saw projects bleed more than $115 million. Here’s a detailed breakdown:
Mango Markets: Largest Theft of the Day – $115M
- Platform: Solana-based DeFi project for borrowing, lending, and leverage trading.
- Hack Details: The attacker manipulated the platform’s collateral value perception, borrowing $116 million and plunging Mango’s treasury to a -$116.7 million balance.
- Affected Assets: USDC, MSOL, SOL, BTC, USDT, SRM, MNGO — nearly wiping out Mango’s liquidity.
Debanks’ Rabby Wallet: Smart Contract Exploit – $0.19M
- Platform: Open-source browser plugin for funds transfer across chains.
- Hack Details: An exploit in its smart contract allowed hackers to move user funds. Post-exploit, the hacker funneled 114 ETH and 179 BNB via Tornado Cash.
- Immediate Action: Rabby Swap urged users to revoke their approvals on all chains and warned against fake assistance accounts.
TempleDAO’s STAX Finance: Smart Contract Vulnerability – $2.3M
- Platform: Based on the TempleDAO DeFi protocol.
- Hack Details: A loophole in the smart contract function
migrateStakeled to the breach. Hackers created a deceptive contract mimicking the old one but didn’t transfer funds to the new one, withdrawing 321,155 xLP tokens.
- Impact: This hack slashed about 4% of TempleDAO’s total assets, which stand at $56.93 million.
QAN Platform: Bridge Hack – ~$1.2M
- Platform: Ethereum bridge smart contract.
- Hack Details: Exploiters nabbed 1.4 billion QANX tokens and exchanged them for 3,090 BNB and 256 ETH.
- Total Loss: Approximately $1.2 million.
😈On Oct 12, 2023, @Platypusdefi on AVAX has been exploited for ~$1M in a possible flash loan exploit.
The attacker created a contract to interact with the project’s contracts and gained 7,935.91 WAVAX and 49,648.81 sAVAX.
The stolen funds remain in the malicious contract created by the attacker.
Malicious contract: 0xF2c444572A402ec83B7Cb64E4A9Fc2188F0628F2
Platypus DeFi recovered around $1.98m of the ~$2.2m stolen in a breach on Oct 12, 2023.
The recovery includes 40,963 sAVAX (~$422K) and 104,713 WAVAX (~$977k) from the Exploiter EOA 0x0cD4 to Platypus DeFi multisig 0x068e.
This is in addition to ~$575k recovered from a second exploiter. Multisig Address for Receiving Funds:

😈On Oct 12, 2023, ETH address 0x40F5f17c08547E4eD65d6610D8dAf5E2f049f6D1 lost ~85.3 $stETH to PinkDrainer in 3 different txns.
The PinkDrainer Wallet 1 (0x63605E53D422C4F1ac0e01390AC59aAf84C44A51) initiated these txns, and the transferfrom() function was called. It seems like a contract approval phishing attack.
The address (0x059f30bc3Ce1f7e8B68257DD11Ad0E6c35D299d4) to which the majority amount of ~67.4 $stETH was transferred was in touch with Pinkdrainer contract 1 (0x00000f312c54d0dd25888ee9CDC3DEE988700000) which was funded by PinkDrainer wallet 1.
😈On 12 Oct 2022, the Awakening project ($ATK) fell victim to a flash loan attack, resulting in a ~ $120K Loss.
- Targeted Strategy Contract: The attacker set their sights on the strategy contract associated with the $ATK project, located explicitly at address 0x96bF2E6CC029363B57Ffa5984b943f825D333614.
- Flashloan Exploitation: Employing a flash loan, the attacker orchestrated a swift and coordinated move, siphoning off a significant volume of $ATK tokens from the contract.
- Token Conversion: The intruder astutely converted the $ATK tokens into $BSC-USD.
- Conversion into $BNB: The attacker further converted the $BSC-USD into $BNB by taking another step in the laundering process.
- Obscured Path: The attacker deposited the funds to Tornado.cash
😈On Oct 13, 2023, Beluga Protocol @Belugadex, the multichain stable swap AMM on the #Arbitrum chain, was exploited for ~113 $ETH (~$175K) in a flash loan attack.
The attack, which was initially funded by 0.1 $ETH from #OKX exchange, happened in 21 transactions during which USDT-USDC.e balance was manipulated to make a profit.
The attacker has moved the stolen 113 $ETH worth ~$175K to #MEXC crypto exchange.

😈On Oct 13, 2023, @Wise_Lending protocol on ETH was attacked by the attacker, but the transaction was successfully front-run by a notable white-hat MEV bot c0ffeebabe.eth.
This is the same white hat MEV bot that returned 2,879 ETH (~ $5.4 million) to Curve Finance during its exploit in July 2023.
It front-run the txn by offering ~93.4 ETH ($146.9k) as a bribe.
Additionally, the bot managed to secure its income of 75.79 ETH ($118K) through this exploitative maneuver.
It returned the 169.19 ETH to @Wise_Token. In response, @Wise_Token rewarded the bot with 1 ETH. The attacker, in this case, leveraged two critical vulnerabilities to execute the attack:
- Manipulating Share Values through ‘Donate’: The first exploit involved manipulating the value of each share within the lending pool by using the ‘Donate’ function. This manipulation likely created a skewed perception of the pool’s health and assets.
- Precision Loss in ‘withdrawShares’: The second exploit took advantage of precision loss, causing the ‘withdrawShares’ function to return a value of 0. This clever manipulation allowed the attacker to withdraw the donated WBTC, effectively emptying the pool.

😈On Oct 17, 2023, Fantom Foundation (@FantomFDN) suffered a breach of a few Fantom wallets.
The estimated losses from the Fantom Foundation funds are around 💰~$550K, and overall losses across multiple wallets are speculated to be around 💰~$7.1M (~4501ETH)
In an official statement, @FantomFDN acknowledged the breach and informed the community that although a few of the compromised wallets are labeled as “Foundation Wallets,” they were not being used officially by Fantom.
They had been reassigned to a Fantom employee, who was using them as personal wallets.
While the hack investigation is still underway, the cause of the hack could be 🔑private key theft🔓, executed with the help of phishing attacks and social engineering.
More information will be available after the completion of the hack analysis by @FantomFDN.
Stolen funds from the @FantomFDN wallet theft are currently sitting in EOA
😈On Oct 18, 2023, Project The Honest Venture on #BSC has been rugged for ~$58k.

😈On Oct 18, 2023, the @Hope_money_ defi protocol on Ethereum was exploited for 528 ETH in what appears to be a precision loss issue due to a smart contract exploit.
Attack tx: https://explorer.phalcon.xyz/tx/eth/0x1a7ee0a7efc70ed7429edef069a1dd001fbff378748d91f17ab1876dc6d10392
The Hack Flow:
- The attacker opens a position in HopeLend and borrows 2,000 WBTC via a flash loan.
- The flash loan function in the Pool contract adds flash loan fees into the reserve’s liquidityIndex.
- The attacker manipulates the liquidityIndex of the hEthWBTC contract (from 1e27 to 7,560,000,001e27), which results in the precision loss.
- Using this precision loss, the attacker borrowed many assets and redeemed all WBTC collateral to make profits.
As per the official statement from @Hope_money_ ,out of ~528 ETH lost, 263.91 ETH was used by the exploit frontrunner to bribe the Validator (managed by LIDO).
The remaining 264.08 ETH is the profit earned by the exploiter. @Hope_money_ is reaching out to the parties involved in an attempt to recover the lost assets.
To mitigate precision losses:
- Always use the SafeMath library to perform arithmetic operations. SafeMath protects against overflows, underflows, and division by zero.
- Consider using fixed-point arithmetic libraries. Fixed-point arithmetic can be helpful for dealing with decimals without the risk of precision loss.
- When dealing with precision, it is often better to work with integers. For example, if you’re dealing with a token with 18 decimal places, represent all values as integers by multiplying them by 10^18.

😈On Oct 20, 2022, the DD token on the #BNB Chain and the Mango INU (MNGO) token on the Ethereum chain were rugged for $109K and $48.5 K, respectively.
😈 On Oct 20, 2022,, the IDEAL token on #ethereum chain was rug-pulled for $21K.
😈 Health Token on the #BNB chain also suffered a price manipulation #attack on Oct 20, 2022, and lost ~17 BNB.
😈On Oct 20, 2022, $BGEO token’s smart contract on the BNB Chain was also exploited for 12 BNB due to a #smartcontract vulnerability.
😈The attacker, on Oct 23, 2022, had stolen 49,950,000 L2DAO tokens from
@TheLayer2DAO on the Optimism chain.
The hacker exploited a vulnerability arising from an inefficient deployment of the #smartcontract.
Layer2DAO struck a deal with the hacker and repurchased 31,239,677 tokens at $0.001.
By that time, the attacker had already exchanged 16.7 million tokens.
The hasty deal with the hacker was done to protect the free fall of the L2DAO token prices, which had plummeted by 90% after the news of the exploit broke out.

😈On Oct 24, 2023, @MaestroBots (Maestro Router contract) on Ethereum was exploited, resulting in a loss of approximately 280 Ether due to a vulnerability in their smart contract.
Nature of the Vulnerability
The vulnerability was centered around the
0x9239127f function in the Maestro Router 2 #smartcontract, which had an external call vulnerability.
With this flaw, attackers could pass in a token address and fill in the called function as
transferfrom, using the parameters of the victim’s address and their own address.
This allowed them to transfer tokens from the victim’s account to their own.
- Vulnerable Contract: 0x80a64c6D7f12C47B7c66c5B4E20E72bc1FCd5d9e.
- Attack Transaction Details: One of the attack transactions: 0xc087fbd68b9349b71838982e789e204454bfd00eebf9c8e101574376eb990d92
- Additional Loss: Apart from the Ether, the exploit also facilitated the theft of approximately 37M $JOE tokens.
However, 26M $JOE remains in the pool, leading to a price impact of -30 %.
Official Statement & Actions Taken
Maestro confirmed that the router exploit had been identified and addressed.
They updated their router to a safer, exploit-free version, and trading has been resumed.
However, they noted that tokens with pools on platforms like SushiSwap, ShibaSwap, and ETH PancakeSwap will remain temporarily unavailable.
Furthermore, Maestro has pledged to ensure that all affected parties will be compensated.
They are currently devising the most efficient and fair method to process refunds, aiming to begin this process within a day.

- Suspicions arise due to a lack of input validation in the 0xb2bd16ab function of the 0x126c contract.
- This allows arbitrary calls, enabling attackers to invoke the ‘transferFrom’ function and thereby continue transferring out tokens approved to the contract.
