How a poisoning attack works

A scammer imitates a user’s past transactions by using an address that appears similar at both the beginning and the end, with just the middle part being different. They then send transactions to and from this wallet in order to craft a misleading transaction history.

Recently stolen funds

There are about 14 attacks every minute and some of them are very well-planned. Real and fake addresses can match in over 15 characters, making them difficult to spot — especially on a phone. Users might be in a hurry and not paying close attention.
