Microsoft's Bitlocker & TPM encryption combo defeated with a $10 Raspberry Pi::The point of Microsoft's Bitlocker security feature is to protect personal data stored locally on devices and particularly when those devices are lost or otherwise physically compromised. With Bi

It should be noted that this attack was demonstrated on a nearly 10 year old laptop that has the TPM traces exposed on the motherboard.

Most TPMs nowadays are built into the CPU which does not leave them vulnerable to this type of attack.

Too late, Canada's banned Raspberry Pi's already. :(

[–] surewhynotlem@lemmy.world 60 points 2 years ago (1 children)

I don't get the downvoting. This is solid commentary on the Flipper Zero idiocy.

[–] Rai@lemmy.dbzer0.com 20 points 2 years ago

Prolly from people who don’t yet know about the Flipper Canada bullshit hahaha

Its definitely sort or misleading but MS needs to really have its feet held to the fire when it comes to these things. It sort of pushes the narrative in the correct direction which is towards privacy AND security, not a half-ass balance where one or the other or both is compromised or is an illusion altogether

The Outlook stuff has demonstrated how fundamentally irresponsible and unserious they are about their obligation to secure and regulate their own systems, they need all the bad press they can get so they are compelled to do betwr

Because MS designed Lenovo motherboard for them and told them where to put the tpm debug pins? I think you're casting blame at the wrong vendor here.

Doesn't matter how good the software is if the hardware vendor fucks up like that.

[–] Natanael@slrpnk.net 1 points 2 years ago

They're heavily involved with the development of the spec and guidance to OEMs on how to implement it

[–] TORFdot0@lemmy.world 79 points 2 years ago (2 children)

Fake news. Nobody is getting a raspberry pi for $10 lol

[–] f4f4f4f4f4f4f4f4@lemmy.world 31 points 2 years ago (1 children)

I get your joke, but it's even cheaper than a "Raspberry Pi". Pi Pico, one RP2040 chip, that's basically RPi's new version of a Teensy. I just installed one in my GameCube to defeat its "BIOS" and boot from micro SD card :P

Coolest thing I heard all day. Didn't know that was a thing.

[–] Hiro8811@lemmy.world 3 points 2 years ago

With shipping it's more than ten but on it's own it's 6,10 for the H model

[–] bruhduh@lemmy.world 34 points 2 years ago (1 children)

Yet another example of "hardware access is root access"

[–] jabjoe@feddit.uk 4 points 2 years ago (1 children)

As it should be really so you can repair things.

$10.. not really in video. He had a custom PCB made so the pogo pins were on the board, all in one.

Honestly, pretty awesome. Although as noted, this is for older boards without TPM integration in CPU.

It can also be done with a logic analyzer.

[–] LazaroFilm@lemmy.world 10 points 2 years ago (1 children)

The pi is $10. The rest is much more.

[–] Treczoks@lemmy.world 5 points 2 years ago (1 children)

That is a PI Nano. They gave them away for free at a trade fair. I've got a bag of them laying around for my next project.

[–] LazaroFilm@lemmy.world 9 points 2 years ago (1 children)

Pi Pico. With a RP2040 MCU. Which retails for [$9.91 on Amazon](Seeed Studio Raspberry Pi Pico Flexible Microcontroller Board Based on The Raspberry Pi RP2040 Dual-core ARM Cortex M0+ Processor for Gamecube, 1pc. https://a.co/d/0A0hAXX).

I’m sure they were giving away at some events because we’re trying to popularize the new chip to get more devs to jump on board. I use a RP2040 on my current project and it’s a great chip.

[–] SatyrSack@lemmy.one 2 points 2 years ago (2 children)

What does that have to do with the GameCube?

[–] LazaroFilm@lemmy.world 4 points 2 years ago* (last edited 2 years ago)

I’m not quite sure what you’re asking but I believe you are talking about PicoBoot, which is a way to hack your GameCube using a Raspberry Pi Pico RP2040.

And

Edit: I just realized the Amazon sale says GameCube. Makes sense now.

[–] Blackmist@feddit.uk 2 points 2 years ago

Just your standard Amazon SEO product name.

[–] SkyNTP@lemmy.ml 24 points 2 years ago (2 children)

Pis are 10$ again? That's the real story.

[–] circuscritic@lemmy.ca 19 points 2 years ago* (last edited 2 years ago)

It's a Pi Pico (RP2040), which is an MCU, not CPU. Similar to an Arduino UNO (ATmega328p).

[–] trackcharlie@lemmynsfw.com 13 points 2 years ago* (last edited 2 years ago)

The concept and implementation of TPM use has been a joke since inception.

veracrypt or luks; bitlocker is a total joke.

[–] stevedidwhat_infosec 12 points 2 years ago

Unsurprised. Physical security seems to be a lot tougher for the industry to “nail”

Just look at this UEFI boot fail vuln/exploit. Crazy.

[–] gennygameshark@lemmy.world 7 points 2 years ago

Yet we still can't crack Denuvo...

[–] homesweethomeMrL@lemmy.world 4 points 2 years ago (1 children)

Hey - hey member that time when Truecrypt was like, “Peace, we out. Use bitlocker. lol”

When’s the new Truecrypt coming out? Yeah yeah Veracrypt, I know. It’s cool, its just not. I dunno.

I know, I know.

Requires physical access. A non-story outside of cybersec academia/research

[–] Natanael@slrpnk.net 17 points 2 years ago (1 children)

Bitlocker's threat model is physical access, though. And it's 50% of TPM's threat model too.

[–] LainTrain@lemmy.dbzer0.com 0 points 2 years ago* (last edited 2 years ago)

Yeah which is why no one cares about either. The threat vector is usually not discussed and mostly ignored by non state-level actors in practice.

I do agree that it's fascinating. My master's degree thesis was on sourcing trust and eliminating various evil maid type attacks, including supply side targeted poisoned hardware aimed at state level.

[–] Netrunner@programming.dev 2 points 2 years ago

This is categorically false. Laptops are not a story but rather company property.
