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.

Wallet holder loses $1.65M after signing an unlimited token approval on a fake exchange
In early July 2026 a crypto wallet holder connected to a fake exchange site and signed a malicious contract approval that gave the attacker unlimited spending rights. An automated sweeper then emptied the wallet of about $1.65 million. Anyone who signs approvals on unfamiliar trading sites is at risk; check and revoke token approvals you do not recognise.
