  • I used to do some work with Qualcomm and ARM IP. They both need to die. ARM is holding back all manner of technologies with their absolutely insane and byzantine licensing scheme and Qualcomm is one of the most evil tech companies in existence, you just don’t hear about them because their particular evil is constrained to B2B interactions.


  • Did you read the article? There were a couple cases were very early Android phones were modified to appear to be off but stayed on. This is fairly common knowledge, but it’s not particularly hard to defeat.

    Everything your phone does requires a deterministic amount of power. Spying on people in particular requires even more power than normal because you need to run the power hungry gps in addition to the modem and cpu.

    If you turn off the device it should be significantly cooler to the touch, not a degree above ambient. If it’s at 100% charge but a power bank with a read out is showing it still charging, that’s a problem. Is the bootloader image different? You can verify that to some extent. When you turn it back on has it been drawing down the battery anyway? Does it require an unlock password instead of biometrics as it normally would (assuming a particularly sloppy setup)?

    This isn’t rocket surgery, in reality nobody is modding everyone’s phone to stay on forever because unless you’re an absolute troglodyte (aka the fucking old school mafia bosses they did this to) it’s going to be painfully obvious your phone is acting weird.




  • If you absolutely have to hand over your phone, turn it off completely, like hold the power button and then tap the off icon. That will dump any keys out of RAM, which is why it always requires the full password to unlock when you turn it back on. Both in terms of how your phone works and the leaks we’ve seen, the cracking tools the police have are overall significantly less likely to be successful when used on a phone that’s been turned off and not unlocked since.

    Also, IIRC iphones have a feature where they will dump at least some of the system keys from RAM if you push the lock button five times. I’d still trust fully off more but that’s easier to do covertly.
