In October 2026, security firm SlowMist identified a phishing campaign targeting Ledger hardware wallet users through fraudulent firmware update notifications. The campaign opportunistically exploited user anxiety following the separately documented CryptoBilis supply chain incident, directing victims to counterfeit 'Genuine Check' verification pages designed to harvest 24-word Secret Recovery Phrases. The attack is distinct from the CryptoBilis hardware implant incident but shares its victims and timing.
