Hi all,
If an attacker has the first 6 words (in the correct order) of my 12 word Trezor backup seedphrase, how long would it take the attacker to brute force crack the remaining 6 words?
Is it necessary for me to wipe the device and create a new seedphrase?
I don’t know how long it will take, but if you use a hidden wallet, hackers will not be able to get the assets in the hidden wallet.
Based on the numbers achieved by this guy, you could do it in 57 thousand years.
This scales with the number of GPUs you’re throwing at the problem: get 10 000 times as much (seems achievable today) and you can be done in less than six years.
A powerful quantum computer, the kind that could maybe exist in six years, could do it in two.
That buys you more than enough time to move your funds to a different seed, which you should absolutely do regardless.
