Crypto transaction monitoring refers to the practice where malicious actors observe blockchain transactions to identify potential victims for scams, such as address poisoning attacks [00:00:00].
Address Poisoning Attacks
An address poisoning attack occurs when an attacker monitors a user’s transaction ledger, like EtherScan, after an incoming transaction [00:00:07]. The attacker then sends a small transaction to the victim, using an address that closely mimics a legitimate one the victim frequently uses, such as their own wallet address [00:00:16].
How the Attack Works
The attacker creates a crypto address that looks very similar to a target’s legitimate address [00:00:21]. They achieve this by making the first and last characters of the fraudulent address nearly identical to the legitimate one [00:00:29]. This is effective because, in certain browser views or interfaces, the middle characters of an address might not be fully displayed [00:00:33].
User Vulnerability
If a user is not paying close attention, they might inadvertently copy the poisoned address from their transaction history [00:00:39]. Believing it to be the correct wallet they intended to send funds to—perhaps even one of their own wallets—they might accidentally send a large sum of money to the attacker’s address [00:00:44]. This type of attack has resulted in individuals losing significant amounts of money [00:00:51].
Prevention
To mitigate the risk of address poisoning attacks, users should always:
- Be aware of this type of scam [00:00:54].
- Verify crypto transaction addresses by using the direct source from where the address was copied [00:00:57].
- If copying an address from one’s own wallet, thoroughly verify that it is the exact address intended for the transaction [00:01:01].
