COLDCARD's X account posts fake 'security migration' phishing link
On 11 October 2026 the official X account of hardware wallet maker COLDCARD published an unauthorized post claiming a flaw in recovery phrase generation in newer firmware and urging users to move their Bitcoin through a 'security migration' site that impersonated COLDCARD. The company deleted the post, said it was investigating how it was published, and said it found no matching login or session record despite offline 2FA. No losses were confirmed. The only official site is coldcard.com; never enter a seed phrase on any website.

Tampered Ledger wallets from an Asian reseller leak seed phrases; on-chain estimate puts losses near $102M
Ledger hardware wallets sold by CryptoBilis, a Southeast Asian reseller, had a hidden implant added after manufacture that read the 24-word recovery phrase during setup and sent it out over an LTE eSIM. Coordinated drains began on 9 October 2026 across TRON, Ethereum, BNB Chain, Polygon, Solana and Bitcoin. Bitquery's on-chain estimate is about $102M from 324 wallets, and investigator Specter put it above $86M. Ledger has not confirmed a figure. Anyone who set up a Ledger bought from a third-party seller in the affected markets should move funds to a new seed made on a device bought direct.

Brevo login flaw lets attacker email a fake Trezor 'STM32 entropy' alert to 347,000 subscribers
An attacker abused an authorization flaw in email platform Brevo to reach 138 client accounts and send phishing from six of them. One was a fake Trezor 'Critical Security Alert: STM32 Entropy Vulnerability' sent to about 347,000 Trezor newsletter subscribers, linking to an app that asked for wallet backups; BitBox's list and CoinTracking (a fake 'refresh API keys' email) were also used. Trezor took the phishing domain down within 20 minutes; about 2,500 people opened the link and no losses have been reported. Recipients should expect follow-up phishing to the same addresses.
