Passphrase Security in Crypto Wallets | Cold Card Incident Raises Concerns
Amid spike discussions in crypto forums, users are questioning the integrity of wallets protected by passphrases in light of a recent hardware wallet incident. Can these wallets truly be vulnerable, despite their passphrase protection?
Context: The Cold Card Mishap
A conversation ignited when people began dissecting whether hackers could exploit wallets with passphrases, especially after the incident involving hardware wallets like Trezor. Comments emphasize concerns over the strength of passphrases and the possibility of hackers targeting seemingly empty wallets.
Interestingly, some users pointed out that Trezor owners can input their passphrase either on the device or through a computer or phone. "Entering on the PC has a risk of keyloggers or USB sniffers grabbing the passphrase if the PC/phone is compromised," a commenter noted. If compromised, the wallet's security relies solely on the seed phrase, which could be dangerous.
Key Themes Emerging from the Discussion
Brute Force Vulnerabilities: A user claimed, "A standard password could be brute forced in 1-24 hours," spotlighting the critical nature of passphrase strength.
Decoy Wallets Misconception: Another user clarified that wallets showing zero balances may act as decoys: "If the hacker doesn't know the secret passphrase, the wallet will show 0 balance make him feel like it's empty and move on."
Passphrase Naming Issues: There is minor concern over the term "25th word" when discussing passphrases, with users arguing it undermines passphrase security. Instead, one recommended a robust 7-8 word passphrase for added safety.
