TREE NEWS update: Binance rebuilt its wallet systems and revoked compromised credentials after attackers used tampered installers, fake job interviews and internal AI tools to reach its wallet signing service in an incident disclosed Oct. 29. Coinbase said over 99% of customer assets sit in cold wallets, while Trezor confirmed hardware implants in three Safe 5 devices sold via CryptoBilis and cut its authorized reseller network by about 80%. South Korea’s FSC is pressing exchanges to raise cold-wallet ratios.
Binance, Ledger, Trezor tighten security after AI-era breaches
The common thread is that the weakest points are no longer the cryptography but the human and supply-chain layers around it — fake recruiters, tampered installers and resold hardware. That shifts the security burden onto users and resellers, not just exchange engineering teams, and explains why a regulator is now pushing cold-wallet ratios as a policy lever. Whether reseller consolidation and cold-storage mandates actually close these gaps, or simply move the attack surface, is the open question worth tracking.
