Bitcoin News summarizes Praveen Perera's research suggesting the attacker ranked vulnerable addresses by balance, swept them in batches, left UTXOs because of a default 200-record API limit, and left 75 BTC and 153 unreproduced addresses unexplained. Held as a dated technical finding. The claims are attributed to Perera and are not independently verified here.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
