How it happened
- Investigators suspected that a single administrative private key had leaked, according to reporting quoting BXH and PeckShield.
- That authority was used to drain BSC funds.
- BXH contacted police and offered a recovery bounty. The cited interview did not establish whether malware, an insider or another route exposed the key.
