Security researchers at Ledger Donjon discovered a critical vulnerability in Tangem hardware wallets that allows attackers to bypass the built-in security delays and attempt password guessing at 2.5 attempts per second instead of the normal rate-limited speed. This vulnerability uses a "tearing attack" combined with electromagnetic emissions analysis to determine correct passwords without triggering security countermeasures. The attack requires physical access to the card and about $5,000 worth of specialized equipment, but can reduce password cracking time from years to hours or days for weak passwords. Since Tangem cards cannot be updated, users must rely on strong passwords (8+ characters with digits, letters, and symbols) as their primary defense. This video breaks down the technical details in simple terms and explains what Tangem users can do to protect themselves.
