I worry that they might sell it as a reason backdoors are necessary: if only we had backdoors, we could've saved those patients! The flaw of this logic would be lost on most lawmakers.

Humor me... if encryption had a backdoor, then ransomware could be effectively mitigated.... Though I'm not a proponent of backdoors by any means, I don't see the logical flaw here.

Only if the bad guys use the NSA-backdoored encryption.

To be completely fair, it's not the NSA's fault that software has faults. Its the software manufacturers'. The ethical concern here is whether the NSA should have reported the holes to the manufacturers and the failure to handle its privileged knowledge in a safe manner.

I agree about this ethical concern, but this attack also shows that reporting the holes to manufacturers is of limited use -- these exploits have been known to manufacturers since at least March, and while patches have shipped, the computers remain vulnerable. Clearly, automatic security updates are still not aggressive enough to prevent these kinds of problems. Though it isn't clear from the article how out-of-date…

No-one running a large organisation's IT systems is going to be letting individual machines just install whatever updates the software maker feels like pushing, even on Windows 10. That would be a big risk in itself: plenty of software makers, including Microsoft, have pushed horrible breaking changes in updates in the past.

Personally, where I would point the finger squarely at Microsoft is in its recent attempts to conflate security and non-security updates. Plenty of people, including organisations who are well aware of what they're doing technically, have scaled down or outright stopped Windows updates since the GWX fiasco and other breaking changes over the past few years.

This also leads to silliness like the security-only monthly rollups for Windows 7 not being available via Windows Update itself for those who do update their own systems (not that this matters much if Windows Update was itself broken on your system by the previous updates and now runs too slowly to be of any use). Instead, if you don't want whatever other junk Microsoft feel like pushing this month, you have to manually download and install the update from Microsoft's catalog site. Even then, things like HTTPS and support for non-IE browsers took an eternity to arrive, and whether the article for the relevant KB on Microsoft's support site includes things like checksums to verify the files downloaded were unmodified seems to be entirely random.

I get that Microsoft would like everyone to use Windows 10, but since for some of us that isn't an option or simply isn't desirable. Since we bought Windows 7 with Microsoft's assurance that it would be supported with security patches until 2020, this sort of messing around is amateur hour and they really should be called out on it a lot more strongly than they have been.

> The solution to malware is obscurity. Have an OS that no one wants to break into ... ... and you'll have an OS for which neither malware authors nor legitimate software developers want to write applications. There's a trade-off involved. We could all use pen an paper and be invulnerable to malware, but then how would we post on HN?

That's my point, as I type this on fully patched Win 10 Pro. Certainly Windows has its issues, but it's biggest 'flaw' when it comes to malware isn't that it's closed-source, but that it's ubiquitous and therefore a highly attractive target.

Linux is ubiquitous in the data center. We are not a low-value target. Also, corporations with cloud-based infrastructure are more likely to pay large ransoms for their data, especially if it is the backup/archive system that is attacked.

Yes, it actually is. Life critical systems should be small, fully open stack, fully audited, and mathematically proven to be correct. Non-critical systems, secondary information reporting, and possibly even remote control interfaces for those systems should follow industry best practices and try to do their best to stay up to date and updated. Most likely many modern pieces of medical technology have not been designe…

Does this distinction between critical and non-critical systems make sense for medical equipment? Displaying the information to humans (doctors and nurses) is probably life-critical. If the display is broken, it's not working. It's not like medical devices have an entertainment system like cars and airplanes.

We already have that distinction in our current regulations... some devices need FDA approval, some don't

I think this is an excellent example that we can all reference the next time someone says that governments should be allowed to have backdoors to encryption etc. This shows that no agency is immune from leaks and when these tools fall into the wrong hands the results are truly catastrophic.

He is not talking about the actual flaws as being the example as to why we shouldn't give the NSA backdoor access; he is saying that the leaks prove that even the NSA can't keep their stuff secret. If they couldn't keep their hacking tools secret, why should we think they can keep their backdoor access secret?

...Because criminals are going to use state-sanctioned encryption software with mandated backdoors? Even if everything off the shelf and open source has some built-in escrow unlocking keys compiled in, hackers are just going to find those code paths and remove them. Encryption works because of certain mathematical principals and laws. Backdoors will only let governments look at legitimately encrypted data and not any…

That makes sense...

So "If encryption had a backdoor" is meaningless. It's really "If a given encryption implementation had a back door" and no one is making the criminals use certain algorithms.

thanks

Let's not pretend that Linux is invulnerable to the class of exploits that make this kind of malware possible [1]. Windows isn't a target because it's vulnerable (all software is vulnerable). Windows is targeted because it's widely used. If the majority of systems were using Linux, malware authors would simply adapt to write malware targeting Linux instead. [1] https://nvd.nist.gov/vuln/detail/CVE-2016-7117

all software is vulnerable This is false, and spreads FUD. It does a great disservice to those who do meticulously maintain their systems, to those who sacrifice convenience and beauty for stability and security, to those who take the time to scrutinize other people's work. It is possible to build and deploy secure software. Linux dominates the datacenter; we are a high value target, and have been for quite some time…

>It is possible to build and deploy secure software.

By secure, you don't mean 100% secure, do you?

So your workstation is next to a bed and is attached to a machine which feeds a drip to keep a little girl alive and it gets your untested patch or whole OS upgrade and the dosage is increased or the driver stops and the patient dies. Only non-critical machines can just automatically apply software patches from Redmond (or anybody). This is not laziness or incompetence - only a few weeks ago military grade exploits f…

Machines like that, which cannot shoulder the risk of applying updates to a network-connected general purpose OS designed to run third party (potentially malicious) code on a non-deterministic non-realtime system... probably should not be using such a system. Patching is risky, not patching is risky. They should have formally validated software running on formally validated deterministic realtime hardware, running in…

I agree. A mission critical MRI machine should not be running an off the shelf OS (Win, Mac, Linux). If you're paying $5 million for a machine, it better have its own real time operating system that had been independently audited.

Now the machine that you pull up the images on is most likely going to be a general purpose PC/Mac. You still need to patch that. Your IT dept needs to have patch cycles that deploy in sets, so all mission critical equipment can be tested before everything gets patched. It takes diligence, and planning. If you prepare at a very large hospital with two MRI machines, then a bad patch can leave you degraded, but not totally offline.

> This shows that no agency is immune from leaks That's well known for a long time. During cold war a lot of Russian weapons were based on the US designs. There is a TV series, Americans, which shows how to manipulate people and steal secrets. Even atomic bomb secrets were stolen (by Klaus Fuchs and others). So I guess a lot of people in military complex make a lot of money on these exploits, PRISM and other projects…

> That's well known for a long time.

But the implications of it are not. Otherwise, no one (including heads of TLAs) could continue to claim that gov't backdoors are a good idea without being widely perceived as an idiot.
