In this video, I send bitcoin to a compromised Coldcard mk3 to see how fast the funds are wiped.
I created 5 wallets:
1. Standard Seed Phrase using the insecure RNG.
2. The same seed phrase with 3 different passphrases (1 word, 2 words, 3 words)
3. The same compromised seed
Here is information on all the mk3 wallets I created, that HAVE BEEN SWEPT by attackers:
Seed phrase only (swept instantly):
bc1qqh58wf33u6vcpurh493j46d23zz7jyn5s06sqn
Seed phrase + 1 word passphrase (swept in 6d 9h):
bc1q4nhqvhyvs342m52h46qw0mkjsejpcncwx4y46t
Seed phrase + 2
I have added NEW PASSPHRASES to a compromised Coldcard mk3 seed for testing.
Whats new?
- Added passphrases to an empty seed phrase
- Added alphanumerical, bip39, and EFF long list passphrases with a range of 35.7 - 51.7 bits
Full breakdown in video below.
I have added more passphrase wallets to the experiment.
I created a new mk3 seed phrase - swept instantly, as expected.
Will upload a video soon that explains the different passphrase strengths.
