Methodology

Attacker had a main wallet from where he sent funds to multiple wallets and then used HOP protocol. He used polygon arbitrum bridge.

He mostly did transaction of 10k and 5k value . He used the bridge 2 different times on all the wallets (190-200 days ago and 100-110
days ago ) I found attacker using script for eligible wallets then checked what addresses they worked with and when and how much funds did they bridge. Found correlation on all subjects.

@Iseeyou23

Thank you for the submission. Unfortunately, this submission does not meet one of the criteria for submissions:

Methodology that has a non-negligible chance of eliminating legitimate users will not be considered

There will need to be additional proof submitted in order to consider this a valid group that does not include any legitimate users. Please consider providing more information about the behavior of these addresses, such as identical types of transactions or similar timing of transactions. Please note that another user that submits an issue with a detailed, non-negligible chance of eliminating legitimate users, their submission will be considered before yours.

For some additional information (if it helps) here is the Hop protocol behavior of the eligible addresses on your list. Good luck!
