LastPass: The Cloud is Public and Ephemeral
More or less, anytime I’m prompted, I’ll take the opportunity to say “The cloud, like its namesake, is public and ephemeral.” In his article, “A Breach at LastPass Has Password Lessons for Us All,” Brian X. Chen comes about as close as a mainstream press reports can without poking the apple-cart of corporate golden eggs over the wall in revealing how stupid it is for anyone to put any critical data on anyone else’s hardware.
The article covers a breach at LastPass, a password management service which invites users to store their password’s on LastPass’s computers somewhere in exchange for letting LastPass keep track of every website you visit that requires a password. For reasons that are a little hard to understand, rather a lot of people thought this was an acceptable idea and entrusted their passwords to what are likely important web services to some random company and their random employees that nobody using the service has ever met or ever will without any warranty or guarantee or legal recourse at all when the inevitable happens and there’s a data breach.
I suppose they believe that because the site appears to offer a service that looks like an analog of a safety deposit box, that there’d be some meaningful security guarantee just as users of gmail seem to assume that if you use gmail your email will be in some way “secure” and “private,” despite what the CEO of google tells you.
Obviously, LastPass was hacked and, obviously, every users’s secure account list (including their OnlyFans and Grindr accounts) and password database was exposed. This is guaranteed to happen eventually at every juicy target on the internet. It’s just probability: an internet service is exposed to everyone on the planet with a network connection (5,569,029,076 people as of today), and every target is attacked constantly (my own Fail2Ban has blocked 2,899,324 malicious packets) and even if they’re Google, they’re not smarter than the 5B+ people who can take a shot at them any time.
The most hilarious part of this is how idiotically fragile companies make themselves by chaining various “cloud services” into their service provision: LastPass was using a Cloud-Based Backup service that was hacked. People.. people.. that level of stupidity is unforgivable, but sadly not remotely criminal (though it should be). The risk of failure in a chained service increases exponentially with the length of the chain. Every dependency is a humiliation. This goes for developers too.
This breach means at least the attackers know every pr0n website millions of users have accounts on (as well as banks etc.) It isn’t clear how easily the passwords themselves will be exposed and LastPass’s technical description suggests a fairly robust encryption process which should be comforting if your master password is a completely randomly generated string of at least 12 characters you’ve managed to memorize, like n56PQZAeXSN6GBWB. If your password is some combination of dictionary words because you assumed, say, the master password was stored securely and you were only risking the password generator’s random passwords on sites (actually, not a bad strategy if you don’t then screw up security by using a commercial cloud-based password keeper that exposes your master password to global attack, but whatever), well if you did that check have i been pwned regularly for the next year and change every password you have.
The big lesson here is if you put your or your company’s data on someone else’s hardware, it isn’t your data any more it is theirs and you should assume that data is, or will soon be, public. So do not ever put critical data of any sort on anyone else’s hardware ever. It’s just stupid. Don’ t do it.
If you insist on doing so because, say, you’re not an IT person but you’d still like email or you’re a small company who can’t afford to hire an IT person, or who’s CIO has cut some side deals to “cut costs” by firing the IT staff and gifting the IT budget to his buddies running some crappy servers somewhere (and for some reason you haven’t fired that CIO yet), I’d suggest you have your lawyers carefully review recourse in the event of incompetence or malice. My personal starting point is to ask questions like the ones in this post and make sure the answers give comfort that the provider’s liability matches your risk.
What we need is a legal framework that makes every bit of user data a toxic asset. If a computer under your care has other people’s confidential data on it and that data is exposed to any parties not specifically and explicitly authorized by the person to whom the data is pertinent, you should be subject to a penalty sufficient to not just make a person who is harmed by the breach whole, but sufficient to dissuade anyone from ever taking a risk that could result in such an exposure again.
Companies who have business models that involve collecting and storing data about individuals should be required to hold liability insurance sufficient to cover all damages plus any punitive awards that might arise from mishandling or other liability. It is reasonable to expect that such obligations would make cloud services other than fully open/exposed ones with no personal data absurdly unprofitable and end them entirely; and this would be the optimal outcome.
PGP Usability Regression thanks to Enigmail
The latest auto update to Enigmail, the essential plugin for Thunderbird for encrypted mail, is a fairly dynamic project that occasionally makes UI and usability decisions that not everyone agrees with.
The latest is a problem for me. I use K9 for mobile mail and K9 doesn’t support PGP/MIME, but Enigmail just:
Why? OK – PGP/MIME leaks less metainformation than inline PGP, but at the expense of compatibility. K9 should support PGP/MIME, but it doesn’t. Enigmail should have synchronized with K9 and released PGP/MIME when mobile users could use it.
But encryption people often insist that the only use case that matters is some edge case they think is critical. They like to say that nobody should read encrypted mail on a mobile device because the baseband of the device is intrinsically insecure (all cell phones are intrinsically insecure – phones should treat the data radio as a serial modem and the OS and the data modem should interact only over a very simple command set – indeed, the radio should be a replaceable module, but that gets beyond this particular issue).
For now, make sure your default encoding is Inline-PGP or you’ll break encryption. Encryption only works if it is easy to use and universally available. When people can’t read their messages, they just stop using it. This isn’t security, this is a mistake.
Microsoft Spyware Now Being Installed On Win 7
If you’re the sort of person who isn’t entirely happy about the idea of Microsoft claiming the right to copy your personal files, photos, emails, chat logs, diary entries, medical records, etc over to their own servers to sell to whoever they want for whatever they can get for your personal data – into markets that already exist for insurance companies to deny you insurance based on algorithmic analysis of your habits or your friends habits or for financial institutions to set your interest rates based on similar criterion, or perhaps even for law enforcement to investigate you without a warrant, then OBVIOUSLY you would never, ever install Windows 10 under any circumstances.
Well, Microsoft seems to have fully jumped on the Google/Facebook gravy train and is now completely invested in stealing your data and selling it to the highest bidder (Apple has been exfiltrating your data for a long time, but so far for internal use). I’ve become more suspect of Microsoft’s updates since they made the Windows 10 advertisement an important (not optional) update (important for what? their bottom line, obviously). Turns out that the latest updates to Windows 7 are pushing Microsoft’s new business model of stealing your data for profit to Windows 7 and 8.
Staying safe is going to require ever more vigilance. It may be possible to block windows components from reaching out to microsoft’s servers at the personal firewall level and certainly it can be done at the corporate firewall level (and should be), but blocking Microsoft is a somewhat complex issue. You can’t run Windows safely without installing security patches because the underlying OS is so completely insecure that new, critical, exploitable flaws are discovered every single week. If you don’t constantly patch these security failures, you will be hacked by people other than microsoft. If you install the wrong microsoft patch, you will be hacked by microsoft. Debian anyone? Also, software developers developing enterprise software, please, please, please stop developing for that horrible, insecure, performance hobbling abomination of a tarted-up single-user OS “Server” and focus on a secure, stable server OS like FreeBSD. Please. I hate, hate having to fork over $1k to microsoft for each box to run their horrible OS just so I can run your software. Why do you support that extortion? Do you despise your customers that much? Stop.
If you care about corporate governance and data security or HIPAA compliance, you are probably violating some critical requirements by installing windows 10 or these new updates to your existing Win7/8 base if you do not block data exfiltration to Microsoft’s servers. This is spyware. These updates are stealing your data and sending it to Microsoft. If your business is subject to data privacy laws, these updates put you in violation of those laws. Microsoft is doing something that is extremely significant and extremely evil and completely wrong. Take action or you may very well be facing personal or corporate consequences. srsly.
I am a strong believer in data privacy and extremely suspect of what I consider highly disingenuous business practices like Google’s but I recognize that there are reasonable people out there who think Google isn’t evil. However, this windows 10 issue, now being pushed to windows 7, goes well beyond Google taking advantage of people’s historical assumptions about the security of email to offer them a free look-alike honey trap to gather their data. Windows 10 and these Win 7 updates are intrusive, not merely misleading. Do not update. Srsly. Do not update. Block the spyware “hotfixes.”
- Russia considers banning windows 10
- Bit torrent trackers ban Windows 10 users
- Windows 10 steals so much data it breaks your data plan and costs you money
- Windows 10 is spyware, plain and simple, including a keylogger.
Stop Gap Fixes
In researching these updates, I came across this article on techworm that has a nice summary of the Malware updates Microsoft is pushing out (with some additional amendments I found):
- KB2952664 (this one reappears no matter how often you unselect it or hide it – so memorize it as evil)
- KB2976978
- KB2977759
- KB2990214
- KB3021917
- KB3022345
- KB3035583
- KB3044374
- KB3068708
- KB3075249
- KB3080149
- KB3112343
- KB3123662
- KB3123862 (new)
- KB3173040 NEW – “final” full screen nag advertisement for Win10 malware
With a whiff of irony, this google search “telemetry site:https://support.microsoft.com/en-us/kb” shows these patches and many more…
Do not automatically install Microsoft updates. You must turn that feature off or you will keep getting additional spyware installed. Go to windows update and verify your settings. I have mine set so windows downloads the updates (so the updates are waiting locally), but I don’t let windows install them automatically. That gives me a chance to review the updates and look for spyware.
When you get updates, you now have to check each one of them to find out if it is spyware or not. The list above is current as far as I know, but clicking on the “more information” link to the right of the updates list will get you microsoft’s marketing speak obfuscation of the true purpose. Any update that “adds telemetry points” or something like that is spyware. Uncheck the install and hide the update. Note that some of these were moved from “optional” to “important.” Microsoft is absolutely intent on stealing your data and is taking some pretty underhanded steps to make it difficult for you to avoid it.
If updates get past you or it turns out later that a seemingly important or innocuous update was spyware (the fun part is that you now have to be vigilant and look all this stuff up), then you can uninstall them from the “installed updates” control panel.
Work to be done
I’ll start looking into firewall settings to block communication to microsoft’s servers. This is a standard anti-malware technique and should work here, except that microsoft has so many servers it is more challenging to block them than your typical malware botnet.
We need something like a variant of Peer Guardian to block microsoft’s servers using the standard P2P crowd-sourcing model to keep the list up to date. I’m not aware of anything like this yet, but I’m looking. Microsoft has become more of an enemy to privacy than the RIAA ever was.
UPDATE: this superuser answer includes a list of telemetry endpoints to block at your firewall or router. Alternatively you can edit your hosts file and add these entries from DSL reports.
Larger Significance
This shift in business focus by Microsoft from providing a product people are willing to pay for to stealing data from people to sell on the commercial market has some significant lessons for the entire software model.
It isn’t just that Microsoft is now adopting Google’s business model of giving away “free” goodies as traps to collect product (you) to sell to the highest bidder, but that the model of corporate trust that underpins most of the security assumptions the internet is built on is manifestly false and unsustainable. If any hacker tried to create these spyware updates, locked-down computers that only install signed code would refuse to install them. Ignoring for the moment that the signed code model is idiotically flawed as signing keys are stolen all the time, this microsoft spyware is properly signed with legitimate keys. It will be installed on locked down computers without complaint and will not show up in commercial anti-virus software. But it is spyware. It contains keyloggers and extremely productive data exfiltration code that is currently copying wholesale data dumps from unfortunate victims to Microsoft’s servers in such volume that their data caps are being hit.
If a non-commercial third party (e.g. “hacker”) did this, they’d be prosecuted. It makes no difference to you that your data is being stolen by Microsoft rather than by some clever teenager in a former eastern block country: your data is being stolen. But the model that has been promoted, a model of centralized corporate trust to validate the “security” of your system has been utterly and irrevocably shattered. This isn’t an accident, isn’t something that better data management might have prevented, this is an intentional ex post facto rewrite of the usual, customary, and regular assumptions we have about the privacy of our computer systems and one that significantly impacts the security of almost everyone in the world: military, medical, legal, fiduciary, as well as personal.
And even if you trust Microsoft (for whatever bizarre, irrational reason), Microsoft is creating a whole series of security holes in their already crappy and insecure operating system that will be exploited by third parties. By adding keyloggers and data exfiltration tools to the core OS, they’re making it even easier for non-corporate hackers to jump on the data theft gravy train. Everyone profits but you. You lose.
