Such is the tragedy of USB I suspect: all we need is serial ports, and it's extremely hard to prove that's all we'll be doing.

One could imagine a more sophisticated USB Condom that has a basic uC to implement (only) USB serial on both sides.

If you need all kinds of "condoms", each allowing a single protocol, you lose the "universal" part. It would be just as annoying as specialized adapters.

Also no one would have one for serial.

Not sure who was first(as the article linked isn't dated), but remember seeing something a few years back that someone else created as a business Linux card Tracked it down: https://hackaday.com/2019/12/24/now-even-your-business-card-... https://www.thirtythreeforty.net/posts/2019/12/my-business-c... This design looks better. Both creative Edit: somehow I duplicate posted when I edited my last comment, qchris beat me…

Okay but what everybody skipped is explaining why would you need a business card running Linux. I mean, except for showing off to fellow nerds.

If it's one you designed and implemented yourself, it's both a business card and a portfolio.

"Hey, stranger! Here's my card. Plug it into your computer's USB slot." Cool project, but as a business card, making someone think they're about to install Stuxnet might not be the best first impression. Heh.

Disappointed seeing a negative comment at the top. This is a COOL project: BADASS even. You’re not technically wrong, but the world advances much more via optimism than pessimism. To the creator: Rock On Dude. So so so cool.

One can be impressed by the effort and ingenuity (I am) and still question the premise. Business cards have a purpose — to provide info about a person/company. This implementation defeats that purpose.

Plugging in any USB data device is prohibited by most infosec policies. Even if it wasn’t, it’s generally not a good idea. Not everyone has an isolated second computer.

I would argue the business card isn’t the card itself but the blog post detailing how it was made.

Edit: author agrees.

It’s all fun and games until your wife’s nudes or your most private messages are leaked.

The world would be a much better place if we all agreed everyone’s naked under their clothes and it’s no big deal. Oh and most grownups have consensual sex occasionally. Shocker! And they drink too :O Sometimes even break minor laws!!

Human nature is not infinitely malleable. A video of a woman sucking a dick becoming public will always be humiliating to almost everyone.

This card does look better. But who would bootup a person's "card", seems like there's a virus waiting to happen.

"Booting up" [suspicious device] isn't really a security risk. It's it's own hardware with no access to anything else you own.

Plugging it into your PC, which this one seems to almost require, is the dangerous part of course, but not any more so than plugging in any other USB device. The fact this runs Linux is essentially irrelevant. A promotional USB stick, charging cable, battery bank or whatever other USB gadgets marketing departments throw around these days could hurt you just as easily.

What, just based off of the custom-ness of the device? I think the endgame of this type of security-by-obscurity is like a randomized FPGA computer trying to fool a hypervisor in the same chip.

More or less, yes. A backdoor has to be able to pattern match to find what it's backdooring; the more custom your implementation is the harder that should be. AIUI, it would be easy to make, say, a CPU that recognizes gcc doing a compile natively. It would be, I think , extremely difficult to create a CPU that recognizes the instructions to emulate a MIPS processor running gcc, especially when the emulator didn't eve…

This is roughly how the game obfuscation layers work to prevent crackers. If it takes weeks for top hackers to crack a game, there's no way it will be done automatically by the chip that was taped out before the VM was generated.
