Should International Travelers Leave Their Phones At Home? (freecodecamp.com)

Long-time Slashdot reader Toe, The sums up what he learned from freeCodeCamp's Quincy Larson: "Before you travel internationally, wipe your phone or bring/rent/buy a clean one." Larson's article is titled "I'll never bring my phone on an international flight again. Neither should you." All the security in the world can't save you if someone has physical possession of your phone or laptop, and can intimidate you into giving up your password... Companies like Elcomsoft make 'forensic software' that can suck down all your photos, contacts -- even passwords for your email and social media accounts -- in a matter of minutes.... If we do nothing to resist, pretty soon everyone will have to unlock their phone and hand it over to a customs agent while they're getting their passport swiped... And with this single new procedure, all the hard work that Apple and Google have invested in encrypting the data on your phone -- and fighting for your privacy in court -- will be a completely moot point.
The article warns Americans that their constitutional protections don't apply because "the U.S. border isn't technically the U.S.," calling it "a sort of legal no-man's-land. You have very few rights there." Larson points out this also affects Canadians, but argues that "You can't hand over a device that you don't have."

Ways around this

[Anaerin]

Depending on how long you're staying, you could send your phone via courier to meet you at your destination. Of course, then you have to trust the courier company and the customs agents handling the package.

He has some skills, but the idea that he amassed billions is laughable. He inherited a large amount of money and his investments have not performed as well as the overall market.

And that's based on the best estimate of his wealth. It's quite possible that his wealth is significantly less than he claims. As a concrete example of this, in the disclosures he made as a presidential candidate, he listed some $20M in income from his golf course in Scotland: problem is, it's losing money. The $20M is revenue, not profit.

So, let me throw that back at you and suggest that you are not as smart as you think you are.

I'm using a 64GB sd card a bit differently. Forget copying things back and forth, that's too much hassle with plenty of room for mistakes.

Instead, get a phone with vendor supplied sdcard backdoor (there's plenty of those, just look for root tutorials of your favorite vendors). For example huawei ones look for dload/update.app, This is made of kernel and squashfs image. You can just rip those from internal ROM, except modify the sdcard version /system squashfs slightly so that fstab mounts sdcard partitions to /cache and /data (running whole system off sd is possible too, but a bit involved to bastardize the rom for it). Put the card in, start the phone and voila - entirely different world boots up, remove the card, and its back to original.

I did this mainly because the sdcard image is rooted and heavily customized, while the internal rom is the original vendors (to not void warranty). But as a side effect, this way you get perfect plausible deniability. Without the sdcard, the phone is pretty much stock, with no indication that entirely different world exist on some card that isn't there.

Attack Software

[pubwvj]

So what happens when travelers start carrying attack hardware & software that bites back. Imagine that the border agent sticks your phone into his reader and along with your data your phone injects a virus into his system. This can be done at very low levels. Or your 'phone' might simply send out 200,000 volts of power through the connection frying boarder patrol's expensive equipment.

Sounds like a good plot for a thriller spy movie...

And it's all possible.

yep !

I even used to live there as a student.
I'm not planning to come back any time soon now.
Why bother with all the hassle ?
