  • It’s entirely a nonstarter for entire fucking industries. That’s not hyperbole. I work in one of them.

    Edit: scratch that - If any infosec team, anywhere, in any industry, at any corporation or organization, doesn’t categorically refuse to certify for use any system that is running MS Recall, they should be summarily fired and blackballed from the industry. It’s that bad. For real: this is how secrets (as in, cryptographic) get leaked. The exposure and liability inherent to this service is comical in the extreme. This may actually kill the product.

    E2: to the title’s implication that such trust can be earned: it kinda can’t. That’s basically the point of really good passwords and secrets (private keys, basically): nobody else knows them. To try to dance around that is fundamentally futile. Also: who am I kidding, this shit will sell like hotcakes. Everyone’s on fucking Facebook, and look how horrifically they exploit everyone’s data for goddamn everything. This isn’t much worse than that to the average mostly-tech-illiterate consumer.




  • lol holy shit

    The only thing in the above parameter that was valid was the device serial number. If this request worked, it meant that I could use an “encryptedValue” parameter in the API that didn’t have to have a matching account ID.

    I sent the request and saw the exact same HTTP response as above! This confirmed that we didn’t need any extra parameters, we could just query any hardware device arbitrarily by just knowing the MAC address (something that we could retrieve by querying a customer by name, fetching their account UUID, then fetching all of their connected devices via their UUID). We now had essentially a full kill chain.

    And then he proceeds to make arbitrary changes to his own modem via this exploit as a final proof. Jesus tapdancing christ.
