The exact circumstances around the search are not known. But activist Samuel Tunick is charged with deleting data from a Google Pixel before CBP’s Tactical Terrorism Response Team could search it.
They can and still will run it through a password cracker with a dictionary provided the phone has some method of either exposing the password hash or can be bruteforced on device similar to PIN bruteforcing.
You can refuse a search
Which can lead to an up to 24 hour detainment which CBP has been allegedly doing, so do know the consequences.
Curious, how does that work? 10000 possibilities aren’t many but you get 30s break every 3 failed attempts then 5 more then its every single failed attempts so that’d be ~5000minutes so that’s about 3 days. Assuming they get “lucky” it’s about 1.5 day. I don’t know though what happens after 20 failed attempts, maybe it’s 1min break or 20min break.
Basically, does PIN bruteforcing actually work and if so on what timeframe?
I think Apple has fixed this, but they would remove the battery, hook it up to external power. When unlocking, there was a pause/dimming on the phone to show it was wrong, and the computer hacking it would kill the power before the phone wrote that there was a bogus attempt, so you got infinite attempts.
I don’t think infinite attempts is the issue, I think the timing of those attempts is what practically limit the usefulness of the attack. Here in the Apple example I imagine rebooting the phone takes longer than 30s. Also if one goes to the length of removing the battery of an iPhone to crack it, this is a pretty serious attempt. One better have proper protections in place.
