Microsoft Claims Unauthorized Repairing of Its Devices Would Be a Security Risk (securepairs.org) 84

In comments submitted to America's Federal Trade Commission, Microsoft says repairing its devices could jeopardize protections from the Trusted Platform Module (TPM) security chip.

"Don't believe them," argues a group of information security professionals who support the right to repair. Slashdot reader chicksdaddy quotes their report: The statement was submitted ahead of Nixing the Fix, an FTC workshop on repair restrictions that is scheduled for mid-July... "The unauthorized repair and replacement of device components can result in the disabling of key hardware security features or can impede the update of firmware that is important to device security or system integrity," Microsoft wrote... "If the TPM or other hardware or software protections were compromised by a malicious or unqualified repair vendor, those security protections would be rendered ineffective and consumers' data and control of the device would be at risk. Moreover, a security breach of one device can potentially compromise the security of a platform or other devices connected to the network...."

As we know: Firms like Microsoft, Lexmark, LG, Samsung and others use arguments like this all the time and then not too subtly imply that their authorized repair professionals are more trustworthy and honest than independent competitors. But that's just hot air. They have no data to back up those assertions and there's no way that their repair technicians are more trustworthy than owners, themselves...

There's nothing inherent in repair or the things called for in right to repair laws like providing diagnostic software, diagnostic codes, schematics and replacement parts that puts the integrity of the TPM or the trust model it anchors at risk. Nor does the TPM require that the devices it secures remain pristine: using the same hardware and software configuration as when they were sold by the OEM. After all, TPMs are in Dell computers. Dell makes diagnostic software and diagnostic codes and schematics available for their hardware and I haven't heard Microsoft or anybody else suggest that a TPM on a repairable Dell laptop is any less secure than the TPM on an unrepairable Microsoft Surface.

        That's true. A separate issue is "is Microsoft's statement also true?"

        As a security professional for twenty years, my experience in part confirms Microsoft's statement and in part refutes it. My conclusion is based on something else, though.

        It is definitely easier for me to compromise a system if I have complete documentation and tooling for it. On this point, Microsoft is right. Security by obscurity

    Let me laugh harder.

    Microsoft, and Security?

    The one and same that sells software WITHOUT WARRANTY, or WITHOUT FITNESS FOR A PARTICULAR PURPOSE and contains KNOWN DEFECTS?

    Sorry, I need my data treated confidentially. Microsoft doesn't have the experience in this at all. If it can't be repaired, it will not be purchased. Thats why I build it myself.

    Tablets are good for media consumtion, but I don't store any confidential data on them.

    Desktops are all backed up to a Linux Machine, that has no outside network access.

    repairing any Microsoft device and putting it back in to service IS a security risk.

    Just my 2 cents ;)

      Actually, considering the sheer volume of attacks on Windows systems, Microsoft does a pretty amazing job at keeping their software secure. If you install Malwarebytes on top of Windows Defender you are pretty safe these days

        You must be new here. Other people will remember countless Microsoft atrocities in security, customer service, and propaganda. This is NOT the company I get my security tips from.

      Let's think about the actual threat model here. It's basically a variation on the Evil Maid attack, where someone with physical access to your device while you are not present is able to tamper with it, installing a backdoor or malware.

      One well known example of this is the NSA's TAO operation, where they intercepted Cisco hardware being delivered to customers, installed malware and sent it on to the victim.

      In theory any repair shop may do that too. In practice, it seems like an attacker like the NSA could i

        News Flash: Unless you witnessed the complete construction of the device, verifying each part, and never leave it out of your possession, you're vulnerable to the Evil Maid Attack. Having said that, perhaps you should worry more about Best Buy and the FBI. Really, we live in "interesting times" where most of the more paranoid of ideas has been confirmed as real when it comes to the NSA/FBI/CIA. The safest approach really is to avoid Microsoft entirely.

    I would've expected that kind of crap from Apple, come on Microsoft! The few devices you have on the market are nothing in the grand scheme of things, there's literally no reason to prevent people from repairing their devices other than pure corporate greed.

    • The 'Surface' line is pretty much Microsoft's love letter to Apple's principles, to the degree they are capable of emulating them, so it's to be expected.

    Of course, everyone knows unauthorized reparing of its devices is a security risk... Every time it automatically uploads a patch without the administrators permission it's a huge risk. I wish they would fix that.

    Microsoft is just jealous of Apple's anti-repair stance. They just gotta one-up their biggest rival.

    And we all lose as a result. Repair is good. Keeping computer's going for as long as possible is good. Sustainability good.

    I dunno if anyone from Microsoft reads our garbage, but... don't be like Apple. Most people dislike Apple for their anti-repair shenanigans. They are definitely not a company to be emulating or striving to be like.

    Stick to making operating systems and office suites. You're good at that. You suck at hardware. You always have.

    ... all about preventing Evil Software from infecting your machine? Because if it is, it's not working. If that was the intent, it has failed miserably. Windows machines are still getting pwned by idiot users opening infected documents. Leading, in some cases to ransomware taking down entire city IT departments. Or was it intended to sniff out attempts to copy Microsoft products (illegally) onto multiple platforms without licenses? Because in this case, it seems to work quite well. Never mind the poor fool who only tried to swap out a bad hard drive. The change in hardware finger print is effectively detected and (as a false positive) the Bad Pirate finger is pointed at them.

    This isn't about YOUR security. Its about the security of Microsoft's revenue stream.
