Incident Summary

On September 8, 2025, CoolWallet’s third-party service provider Kiln and SwissBorg received an alert about a possible unauthorized access to staking wallets, leading to abnormal withdrawals of some Solana assets. SwissBorg and Kiln immediately launched response measures, successfully stopped the irregular activities, and involved cybersecurity partners for resolution. To protect users, Kiln halted all staking transactions, forced validator exits, and conducted thorough chain-by-chain investigations to ensure asset safety and integrity. 

During this time, API performance issues temporarily affected the display on CoolWallet staking pages. To prevent user impact, CoolWallet promptly collaborated with Kiln on investigations and continued to monitor the situation. Services have now fully recovered.

Recent reports of stolen crypto assets involving some Ledger users have raised concerns about hardware wallet supply chain security.

According to public reports, Ledger is investigating losses reported by users who purchased devices through CryptoBilis, a reseller in Southeast Asia. Ledger has also requested that the reseller temporarily suspend sales and shipments while the investigation continues.

The full attack method, scope of impact, and responsibility have yet to be conclusively established.

The incident highlights an important security consideration: Protecting private keys inside a secure chip is essential, but hardware wallet security must also account for the possibility of physical tampering before a device reaches its owner.
