Telegram Trading Bot Maestro's 280ETH Hack

In a significant security breach, hackers have exploited a vulnerability in the smart contract of the Telegram trading bot, Maestro, resulting in the theft of 280 Ethereum (ETH), equivalent to around $500,000. This incident has raised concerns about the security of trading bots operating on the popular messaging platform.

The Maestro trading bot is designed to automate on-chain trading and farming, streamlining cryptocurrency transactions. However, some wallets associated with these bots require users to share their private keys, leading to apprehensions about security measures.

The Vulnerability in Maestro Router 2 Contract

Blockchain security firm Beosin reported on Twitter that attackers managed to pilfer approximately 280 ETH due to an external call vulnerability found in the Maestro Router 2 smart contract. Beosin provided insights into the attack, explaining that attackers could input a token address and invoke the "transferfrom" function with the victim's address as a parameter, allowing them to transfer the victim's tokens to their own address via "transferfrom."

Another blockchain analysis company, PeckShield, revealed that a phishing wallet exploited the same vulnerability to steal 37 million JOE tokens. This attack had a substantial impact, causing JOE tokens' price to plummet by over 30%. Due to this sharp drop and a lack of liquidity, Maestro was unable to repurchase JOE tokens to refund affected users.

Maestro Refunds users

Following the security breach, the Maestro team acted promptly. They identified the vulnerability and addressed it by updating their router with a secure, exploit-free implementation. This enabled trading to continue as usual, with the exception of tokens in pools on platforms such as SushiSwap, ShibaSwap, and ETH PancakeSwap, which remained temporarily unavailable.

One remarkable aspect of this incident is that Maestro took responsibility for the security breach and opted to refund all affected users. They accomplished this by purchasing the tokens and sending them to the wallets of the victims, ensuring that every wallet that suffered losses in the router exploit was made whole.

Maestro's Remarkable Earnings

Despite the security breach, it's worth noting that Maestro's trading bot has been extremely successful in 2023. In May of the same year, it was reported that the Maestro trading bot was earning a staggering $5 million in monthly commissions. However, this success has been somewhat tarnished by the security incident, which underscores the potential risks associated with sharing private keys, a practice that contradicts the foundational ethos of the decentralized ecosystem - "not your keys, not your coins."

As the Maestro bot incident unfolds, it serves as a stark reminder of the importance of security in the cryptocurrency space and the risks associated with third-party services. While trading bots offer the potential for significant profits, they come with the cost of entrusting private keys to the bot for transaction signing. In light of the Maestro attack, users are cautioned to remain vigilant and prioritize their security in the fast-evolving landscape of cryptocurrency trading. The Maestro team has clarified that the attack was directed at the router, and user wallet credentials were not compromised.
