Ledger appears to have fixed an Ethereum-related vulnerability without much public attention. For defenders, the main issue is exposure in a widely used crypto hardware wallet product and the need to track vendor fixes even when disclosure is limited.

QSE and Pos Digicert are signaling work on post-quantum readiness in Malaysia. For defenders, this points to an obligation to track cryptographic inventory and start planning for algorithms and certificates that will survive quantum-era risks, especially where identity and trust services are in scope.

Coldcard has changed its signing process after a seed-related exploit, which raises the bar for physical approval of transactions but also signals that some wallets or funds may remain exposed until users act. For defenders, the main issue is exposure management: identify affected devices, validate whether seed material or funds could be at risk, and move assets or rotate keys where needed.
