🚨🚨🚨 #unibot hack, $5.6 M drained, what you should learn from this?💡💡💡

The Unibot hack was a security exploit on the popular Telegram bot that allows users to snipe trades on the decentralized exchange Uniswap. On October 29, 2023, hackers exploited a newly deployed contract by Unibot to drain the crypto holdings of several users. The hackers reportedly stole roughly $560,000 in various memecoins.

The hack went undetected for several days until October 31, when blockchain analytics firm Scopescan alerted Unibot users to the ongoing exploit. Unibot later confirmed the hack and advised users to revoke the approvals for the exploited contract and move their funds to a new wallet.

The underlying issue of the Unibot hack is a CALL injection, which allows an attacker to send malicious call data to the 0xb2bd16ab() method to move tokens approved for Unibot contracts. This exploit is similar to the one that was used to hack the LastPass password manager in August 2023.

The Unibot hack is a reminder of the importance of security in the decentralized finance (DeFi) space. DeFi users should always be careful about what contracts they approve and should only use reputable services.

Here are some tips to help protect yourself from DeFi scams:

Only use reputable DeFi services and protocols.

Do your research before investing in any DeFi project.

Be careful about what contracts you approve.

Never share your private keys with anyone.

Keep your software up to date.

***If you believe that you may have been affected by the Unibot hack, you should immediately revoke the approvals for the exploited contract and move your funds to a new wallet. You should also contact Unibot support for assistance.
