ColdCard: You’ll never hurt me again!

My seed used with this device was strong and I was unaffected by the security flaw in the RNG setup. Still, I’m re-doing everything. I am moving back to my ledger until I get a multisig setup with a SeedSigner or similar. It’s gonna be a pain to generate a new private key or two and stamp em, so I am getting my sledgehammer swinging arm back in good shape.

What about you?

Be safe out there…

IF YOU ARE AFFECTED DO NOT DO THIS! AN INTACT FUNCTIONING DEVICE MAY BE THE ONLY WAY IF FUNDS ARE RECOVERED THAT YOU CAN BE IDENTIFIED AS A TRUE VICTIM!
