# Negotiated Attacker Fees Become Standard Practice

Large on-chain thefts increasingly end in a negotiated partial return where the attacker unilaterally sets a percentage bounty, turning exploits into a de facto pricing mechanism for unfound bugs and weakening the deterrent value of formal bug bounty programs.

## Recent evidence

- [contradicts] Symbiosis Bridge Attacker Minted 46 Billion Fake Bitcoin Tokens and Realized About $336,000 (2026-09-14): Symbiosis offered a 20% white-hat bounty that expired on September 13 with no return, and the protocol instead recovered roughly 15 BTC itself into a team multisig. The negotiated-fee mechanism failed here: the attacker declined a bounty set well above the customary 10%.
- [confirms] Blockstream Demands the 598 Bitcoin Liquid Attackers Kept as a Self-Declared Finder's Fee (2026-09-13): The Liquid attackers returned 3,400 of roughly 4,000 bitcoin taken from Blockstream's federation wallet and unilaterally kept exactly 15 percent, about $47 million, as a self-declared finder's fee. The attacker setting the percentage — above the customary 10 percent whitehat norm — is the pricing mechanism the thesis describes operating without the victim's consent.
