This malicious contract involved:
Basically the attacker creates a vanity address very similar to your own, and send you very small amounts of USDT or something in the hope that you’ll check balance on BlockScan, and one day copy and paste their address and send to it by mistake!
The next time Victim A carelessly copies the address of the historical transaction, it is easy to copy it to the address C prepared by the hacker by mistake, thus transferring the funds to the wrong account.
Sleepy people sometimes do illogical things 🤷♂️ one of the chat users got attacked for 10k$:
TLDR: always double-check any address letter by letter, digit by digit! Whitelist your working addresses!
Questions began to be raised over the discovery of mysterious outgoing zero transactions with supposed approve signatures…
Check out this example, seen both at Tron and Ethereum Main-net:
This address (Attacker): etherscan.io/address/0xfe3c53086f256219b81a6afbf614cd839c1c5982
Is interacting with this smart contract (and other similar ones): etherscan.io/address/0x23dd013da6d35b3271c9199e38d659e763e38463
Creating transactions like these: etherscan.io/tx/0x7da7966512de60eef5c494407782bddf569d1cfb42793f0afe77ee9e2edc16bf
Another example (Tron):
At the same time, all of the customers reported that no one had signed such approves! In a nutshell, it’s the identical spam attack as in the previous example!
The transferFrom function was called, not transfer, which means that the From address was supposed to give that address who signed the transaction, but since the sum is zero and all new contract memory cells are initialized with zeros, everything runs smoothly (since there is a 0 for any address) (deepl.com) 🤔
TLDR: You must just ignore these transactions!
Here, an attacker is sending 0 transactions in hope someone will copy last receiver address and send crypto by mistake - like in a clipboard (clipper malware) attack!
Unlike the first attack the attackers may also first wait for you to ask about strange transactions somewhere on Twitter and then finish scam with using social engineering in DMs!
Once again, ignore them, if you are worried about stolen seed - migrate funds via:
If you still have to revoke approvals at Tron — you may use cointool.app with caution!
Support is very important to me, with it I can spend less time at work and do what I love — educating DeFi & Crypto users!
I don’t have as much money as the fictional character in our essay, but your support helps me to exist 🙂
