History of Attacker’s Identity

Team was Contacted by Attacker Before the Incident

  • The team has communicated with attackers several times before the incident.
  • September 15th: Team was approached by a Discord user UmbralUpsilon, i.e. BogHolder#1688. They asked the team about various parameters in the TWAP oracle. Although this was not part of the attack, but attacker used this to start the conversation. The team answered these queries since every component of the protocol is open-source. The team always answers the queries of users in the spirit of open-source collaboration. The team then asked the reason for such a question. Then attackers told the team that they were creating an arbitrage bot for the pools.

After the Attack

  • Dillon Kellar and Laurence Day were the core team members who were involved in the conversations with the attacker. They found that the user’s side of the conversations is deleted completely.
  • Here are the screenshots shared by Laurence of the discord chats with the attacker.

Pascal Caversaccio has made the team aware that the attacker has requested some Kovan testnet Ether via Gitter, using the Twitter account ZetaZeroes. The team has reached out to attackers via Gitter.

Here is the screenshots of chats with the attacker shared by the team.

Team has reached out directly to attacker(0xba5ed1488be60ba2facc6b66c6d6f0befba22ebe) with message.

The team has directly told the attacker that: You’re clearly incredibly skilled: this is something that has been overlooked for ten months in production, and you’re the only one that found it. While it would have been so much more productive for you to instead choose to work with us: be the antihero of this story rather than the villain. Take a 10% whitehat, and save a lot of people the effort of engaging law enforcement.

Effect on the Indexed Protocol

  • Damage by attackers is not just financial, but developers are receiving death threats.
  • $16M of assets that the attacker stole are in this address.
