Kitty Poop

Tuesday, June 27, 2017 

Many years ago (21 years, 9 months as of this post), I used some as-of-then only slightly out of date equipment to record a one week time lapse of the cats’ litter box.

I found the video on a CD-ROM (remember those?) and thought I’d see if it was still usable. It wasn’t – Quicktime had abandoned support for most of the 1990’s era codecs, and as it was pre-internet, there just wasn’t any support any more. I had to fire up my old Mac 9500, which booted just fine after years of sitting, even if most of the rubber feet on the peripherals had long since turned to goo. The OS9 version of QT let me resave as uncompressed, which of course was way too big for the massive dual 9GB drives in that machine. Youtube would eat the uncompressed format and this critical archival record is preserved for a little longer.

Telemetry removal script

Saturday, July 30, 2016 

below is a .cmd script for uninstalling all the known telemetry updates (so far) in Windows 7.  These telemetry updates are spyware Microsoft is installing on your computer to send data back to Microsoft.  They have recently begun installing tools to exfiltrate your private files and log your keystrokes to their servers.

While there are people who think Windows 10 is a normal upgrade, there are nations that formally disagree. If you care about privacy; your privacy, your private files, your passwords, accounts, personal data, love letters, medical information, financial information, browsing history, private pictures, etc. not falling into either corporate or criminal hands (via soon to be exploited security holes created by these exfiltration tools) you should consider removing all known telemetry tools from windows 7 and never updating to Windows 10.  And consider suing Microsoft.

If you don’t care about privacy at all, I hear Windows 10 has a pretty GUI.

This script removes all the telemetry (trojan horse) “updates” Microsoft has tried to sneak in so far.

Turn off windows update now!

Monday, March 14, 2016 

If you haven’t already, turn off Windows update now.  Microsoft has recently started installing Windows 10 spyware without consent.  A good friend of mine had a bunch of systems at the company where he runs IT hacked by Microsoft over the weekend, which broke the certificate store for WPA-2 and thus their wifi connections.

To be clear, Windows 10 is spyware.  Microsoft has changed their business model from selling a product to selling data – your data – to whoever they want.  Windows 10 comes with a EULA that gives them the right to steal everything on your computer – your email, your private pictures, your home movies, your love letters, your medical records, your financial records – anything they want without telling you.  “If you’re not paying for the product, you are the product.

If this happens to you,  I suggest contacting your state attorney general and filing a complaint against Microsoft.  Hopefully a crushing class action suit or perhaps jail time for the executives that dreamed up this massive heist will help deter future corporate data thieves, though that’s certainly irrational optimism.

I wish I could recommend switching to Linux for everyone, but there’s a lot of software that still depends on Windows and a lot of users that will have a hard time migrating (developers: please stop developing for Microsoft).  Apple seems unequivocally better in refusing to act as key player in bringing about Total Information Awareness.  I’m not a huge fan of their walled garden and computers as overpriced fashion accessories approach, but it is far better than outright theft.  For those that are slightly computer savvy, there’s Linux Mint, which is quite usable and genuinely free.

These instructions might help prevent that disaster of an update being visited upon you (and possibly law enforcement visits to come after Microsoft starts sifting through all your datas and forwarding on whatever they find).  The latest reports suggest they aren’t enough, but it is the best I have found other than isolating your windows box from the internet completely.

PGP Usability Regression thanks to Enigmail

Thursday, February 25, 2016 

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.

Signal Desktop: Probably a good thing

Tuesday, December 8, 2015 

Signal is an easy to use chat tool that competes (effectively) with What’sApp or Viber. They’ve just released a desktop version which is being “preview released/buzz generating released.”  It is developed by a guy with some cred in the open source and crypto movement, Moxie Marlinspike.  I use it, but do not entirely trust it.

I’m not completely on board with Signal.  It is open source, and so in theory we can verify the code.  But there’s some history I find disquieting.  So while I recommend it as the best, easiest to use, (probably) most secure messaging tool available, I do so with some reservations.

  • It originally handled encrypted SMS messages.  There is a long argument about why they broke SMS support on the mailing lists.  I find all of the arguments Whisper Systems made specious and unconvincing and cannot ignore the fact that the SMS tool sent messages through the local carrier (Asiacell, Korek, or Zain here).  Breaking that meant secure messages only go through Whisper Systems’ Google-managed servers where all metadata is captured and accessible to the USG. Since it was open source, that version has been forked and is still developed, I use the SMSSecure fork myself
  • Signal has captured all the USG funding for messaging systems.  Alternatives are not getting funds.  This may make sense from a purely managerial point of view, but also creates a single point of infiltration.  It is far easier to compromise a single project if there aren’t competing projects.   Part of the strength of Open Source is only achieved when competing development teams are trying to one up each other and expose each other’s flaws (FreeBSD and OpenBSD for example).  In a monoculture, the checks and balances are weaker.
  • Signal has grown more intimate with Google over time.  The desktop version sign up uses your “google ID” to get you in the queue.  Google is the largest commercial spy agency in the world, collecting more data on more people than any other organization except probably the NSA.  They’re currently an advertising company and make their money selling your data to advertisers, something they’re quite disingenuous about, but the data trove they’ve built is regularly mined by organizations with more nefarious aims than merely fleecing you.

What to do?  Well, I use signal.  I’m pretty confident the encryption is good, or at least as good as anything else available.  I know my metadata is being collected and shared, but until Jake convinces Moxie to use anonymous identifiers for accounts and message through Tor hidden nodes, you have to be very tech savvy to get around that and there’s no Civil Society grants going to any other messaging services using, for example, an open standard like a Jabber server on a hidden node with OTR.

For now, take a half step up the security ladder and stop using commercial faux security (or unverifiable security, which is the same thing) and give Signal a try.

Maybe at some later date I’ll write up an easy to follow guide on setting up your own jabber server as a tor hidden service and federating it so you can message securely, anonymously, and keep your data (meta and otherwise) on your own hardware in your own house, where it still has at least a little legal protection.

10 Gbyte Win10 Spyware “upgrade” now forced on users

Sunday, September 27, 2015 

Microsoft has, historically, done some amazingly boneheaded things like clippy, Vista, Win 8, and Win 10.  They have one really good product: Excel, otherwise everything they’ve done has succeeded only through illegal exploitation of an aggressively defended monopoly. OK, maybe the Xbox is competitive, but I’m not much of a gamer.

Sadly for the world, the model of selling users for profit to advertisers and spies has gained ground to the point where Microsoft was starting to look like the least evil major entity in closed-source computing.  Poor microsoft.  To lose the evil crown must be at least as humiliating as their waning revenue and abject failures in the mobile space (so strange… try to enter a space where they don’t have a monopoly to force users to accept their mediocre crap and they fail, who’da thunk it?)

“There is a difference between policy and practice. We don’t read customers mail. We don’t read customer documents. We don’t triangulate YouTube views and searches. We don’t use the content of your Hotmail to target ads in Bing,”

Frank Shaw, Corporate Vice President of Corporate Communications for Microsoft

Well, never fear: Windows 10 is here and they’re radically one-upping the data theft economy by p0wning not just the data you idiotically entrust to someone else’s server for free without ever considering why they’re giving you that useful service for “free” or what they, or whoever buys their ultimately failed business, might do with your data, but also the data you consider too sensitive for the Google or the Apple.  Windows 10 exfiltrates all your data to Microsoft for their use and profit without your information.  Don’t believe it? Read their Privacy Statement.

Finally, we will access, disclose and preserve personal data, including your content (such as the content of your emails, other private communications or files in private folders), when we have a good faith belief that doing so is necessary.

And it is free (as in beer but not as in speech).  What could possiblay go wrong?

Well, people weren’t updating fast enough so Microsoft is now pushing that update on you involuntarily.  Do you have a data cap that a 10G download might break and cost you money?  So what!  Your loss!  Don’t have enough space on your drive for a 10G hidden folder of crapware foisted off on you without your permission?  Tough crap, Microsoft don’t care.

To be clear, Windows 10 is spyware.  If this was coming from a teenage hacker somewhere, they’d be facing jail time.  It is absolutely, unequivocally malware that will create a liability for you if you use it.  If you have any confidentiality requirement, you must not install windows 10.  Ever. Not even on your home machine.  Just don’t.

The only way to prevent this is really annoying and a little risky: disable automatic downloads.  One of the problems with Microsoft’s operating systems is the unbelievably crappy spaghetti code that results in a constant flow of cracks, a week’s worth are patched every Tuesday.  About 1 serious vulnerability every fortnight these days (note this is about the same as Ubuntu and about 1/4 the rate of OSX or iOS, why people think Apple products are “secure” is beyond me – live in that fantasy walled garden!  But nice logo you paid a 50% premium for on your shiny device). Not patching increases the risk that some hacker somewhere will steal your datas, but patching guarantees that Microsoft will steal your datas.  Keep your anti-virus up to date and live a little dangerously by keeping Microsoft out.

Here’s an interesting article: how-to-clean-the-windows-10-crapware-off-your-windows-7-or-81-pc

And a tool referenced in that article: GWX control panel (that can help remove the windows 10 infection if you got it).

And a list of patches I found that are related to Win10 malware that you can remove if you haven’t installed it yet (Windows 10 eliminates the ability to choose or selectively remove patches, once you’re in for the ride, you’re chained in: all or nothing.)

Basic advice:

  • Disable automatic updates and automatic downloads of updates.
  • Review each update Microsoft offers.  This is tedious, my win 7 install reports 384 updates, 5-10 a week, but other than security patches, you probably don’t really need them.  Only install a patch if there’s a reason.  Sorry, that sucks, but there’s always Linux Mint: free like beer AND free like speech.
  • If you’re still on Win 7/8, uninstall the spyware Microsoft has probably already installed.  If you’re on Windows 8, you probably want to upgrade to Windows 7 if at all possible.
  • If you succumbed to the pressure and became a Microsoft Product by installing Windows 10, uninstall it.
  • If uninstall doesn’t work, switch to Mint or reinstall 7.

Most importantly, if you develop software for servers or for end users, stop developing for Microsoft (and Apple too).  Respect the privacy of your customers by not exposing them to exploitation by desperate operating system vendors.  In many classes of applications, your customers buy their computers to run your software: they don’t care what operating system it requires – that should be transparent and painless.  Microsoft is no longer an even remotely acceptable choice.  Server applications should run under FreeBSD or OpenBSD and desktop applications should run under Linux.  You can charge more and generate more profit because the total net cost for your customers will be lower.  Split the difference and give them a more reliable, more secure, and lower cost environment and make more money doing so.

Successful connect to WPA2 with Linux Mint 17

Saturday, September 26, 2015 

I found myself having odd problems connecting to WPA2 encrypted wireless networks with a new laptop.  There must be more elegant solutions to this problem, but this worked for me.  The problem was that I couldn’t connect to a nearby hotspot secured with WPA2 whether I used the default config tool for mint, Wicd Network Manager, or the command line.  Errors were either “bad password” or the more detailed errors below.

As with any system variation mileage may vary, my errors look like:

wlan0: SME: Trying to authenticate with 68:72:51:00:26:26 (SSID='WA-bullet' freq=2462 MHz)
wlan0: Trying to associate with 68:72:51:00:26:26 (SSID='WA-bullet' freq=2462 MHz)
wlan0: Associated with 68:72:51:00:26:26
wlan0: CTRL-EVENT-DISCONNECTED bssid=68:72:51:00:26:26 reason=3 locally_generated=1

and my system config is reported as:

# lspci -vv |grep -i wireless
3e:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b)
 Subsystem: Intel Corporation Dual Band Wireless-AC 7260
# uname -a
Linux dgzb 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I found useful commands for manually setting up a wpa_supplicant.conf file here, and for disabling 802.11n here. The combination was needed to get things working.

The following successfully connects to a WPA2-secured network:

$ sudo su
$ iw dev
 ... Interface [interfacename] (typically wlan0, assumed below)
$ iw wlan0 scan
 ... SSID: [ssid]
 ... RSN: (if present means the network is secured with WPA2)
$ wpa_passphrase [ssid] >> /etc/wpa_supplicant.conf 
...type in the passphrase for network [ssid] and hit enter...
$ sh -c 'modprobe -r iwlwifi && modprobe iwlwifi 11n_disable=1'
$ wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf

(open a new terminal leaving the connection open, ending the command disconnects)

$ sudo su
$ dhclient wlan0

(should be connected now)

United’s Magic Trays

Thursday, September 3, 2015 

@United has new coach trays that are coated with a material that has an amazing coefficient of friction.  They are not sticky at all—there’s no adhesion effect—it is all friction.  Even low surface energy plastics don’t slide on it at all.

The approximately 75-80° angle in the picture is the point at which the cup topples over itself.  It isn’t adhered to the surface and it doesn’t appear to slide at all before toppling.

Super Friction Tray

This would be the perfect coating for a smart phone pad in a car.

Microsoft Spyware Now Being Installed On Win 7

Monday, August 24, 2015 

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.”

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):

With a whiff of irony, this google search “telemetry site:” 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.

Disk Checks for Large Arrays

Friday, August 21, 2015 

If you have a large array of disks attached to your server, which is obviously going to be running FreeBSD or OpenBSD if you care about security, stability, and scalability; there are some tricks for dealing with large numbers of disks (like having 227 4TB disks attached to a single host).

Using Bash (yes there are security issues, but it is powerful)

# for i in `seq 0 227`; do smartctl -t short /dev/da$i; sleep 15; done 1Thanks Jared

executes a short smart test on all disks. Smartctl seems to max out at 32 concurrent tests, so sleep 15 ensures the 3 minute tests are finishing before new ones are executed. If you’re in a hurry, sleep 5 should do the trick and ensure all of them execute.

to get results try something like:

# for i in `seq 0 227`; do echo "/dev/da$i"; smartctl -a /dev/da$i; sleep .5; done

Bulk Fixes

Problem with the disks – need to clear existing formatting?

unmount each disk

# for i in `seq 0 227`; do umount -f /dev/da$i; done

unlock (if needed)

# sysctl kern.geom.debugflags=0x10

Overwrite the start of each disk

# for i in `seq 0 227`; do dd if=/dev/zero of=/dev/da$i bs=1k count=100; done

Overwrite the end of each disk

# for i in `seq 0 227`; do dd if=/dev/zero of=/dev/da$i bs=1m oseek=`diskinfo da$i | awk '{print int($3 / (1024*1024)) - 4;}'`; done

Recreate GPT (for ZFS)

# for i in `seq 0 227`; do gpart create -s gpt /dev/da$i; sleep .5; done

Destroy multipaths

# for i in `seq 1 114`; do gmultipath destroy disk$i; done

Disable multipath completely

# for i in `seq 1 114`; do gmultipath destroy disk$i; done
# gmultipath unload
# mv /boot/kernel-debug/geom_multipath.ko /boot/kernel-debug/geom_multipath.ko.bad
# mv /boot/kernel/geom_multipath.ko /boot/kernel/geom_multipath.ko.bad
