Ill Bloom weak-randomness wallet vulnerability

Weak randomness in wallet seed generation enabled private-key enumeration, with more than $5 million in reported multi-chain losses.

Incident date2026-05-27 Attack typeWallet vulnerability SeverityCritical Involved chainsBitcoin / Ethereum / TRON / Solana

Some software wallets generated seed phrases with weak pseudo-randomness, sharply reducing the effective key space and enabling attackers to enumerate private keys across chains. Public reporting traced affected wallets back to 2018 across Bitcoin, Ethereum, Tron, and Solana.
