TeslaCam, Tesla Can’t

TimeHorse April 20, 2020 2 Comments

I haven’t been able to use the TeslaCam since 27 July 2019. That’s because, around TeslaOS 2019.28.1, Tesla broke most USB Sticks used for Dashcam functionality, because, it claimed, they were too slow.

Not having a DashCam and having such a mysterious and incomprehensible error—my USB stick was fast enough—I was afraid to buy a new USB stick to see if I could get it working again. For months I dithered on the issue, totally unsure what Tesla wanted, and wanting so badly not to waste money on a device that would fail with Tesla.

Compound that with, in December, 2019, thanks to an AutoPilot, #CO2Fre failed to stop when a vehicle with California plates cut me off by jumping into the exit lane ahead of me at the last minute, causing $4,000 worth of damage I can’t remotely afford to pay. The scratches, therefore, remain to this day. And as no solace, I don’t even have the Dashcam video to go over the details even if I wanted to make an Insurance claim. So, I have scratches but still no Dashcam.

Then TeslaOS 2020.12.5 came out, which added support for watching Dashcam videos within #CO2Fre. Since I had the time off thanks to Covidapolis, I decided to try again with the Dashcam, and found this neat video:

Thanks to that video I decided to buy a 2TB SanDisk Extreme Portable SSD drive, a SamSung SXDC UHS-I EVO Select Card, and a Raspberry Pi Zero W.

I didn’t have access to my car because of the hypochondriac until the day of my #CO2Fre demo. I plugged in the SanDisk drive with its USB-C to USB-A adaptor and… nothing. I had the drive plugged in, but no camera was showing, and I couldn’t show off any of the Dashcam features during my entire presentation, including Dashcam footage of the speed test on the main screen after I parked, despite having the drive plugged in. The demo still went well, but I’m annoyed how hard I tried to get this working and still failed.

Afterwards, I tried to play around some more. Doing so requires me to go through decontamination because, for some reason, the hypochondriac thinks #CO2Fre has SARS-CoV-2. Meaning, I have to keep changing my clothes every time I go to the car because sitting in my car contaminates my clothes.

The drive was exFAT, so I reformatted it as FAT32. The drive did flash on the screen after some cord giggling, but it said it wasn’t formatted properly despite having the TeslaCam folder and being named TeslaCam. Since I’ve read that Tesla supports exFAT, I formatted it back as that, and it sits now, unable to connect.

2TB SanDisk
I have a 2TB SanDisk Solid-State Drive USB 3.1 compatible 10GB/s Drive plugging into #CO2Fre with a USB-C connector and a USB-C to USB-A adaptor hooked into #CO2Fre, yet #CO2Fre can’t see it! © 2020, Jeffrey C. Jacobs

I also tried my MicroSD chip with an adaptor. Originally, the chip was supposed to be part of the Raspberry Pi, but I wanted to test to see if it could be used as the TeslaCam directly. No dice. I’d hook up the Raspberry Pi and try with that, but I have to finish updating my Résumé and fix my broken Zone File updater for Reston Writers first. I just have too much going on to worry about going any further with this nightmare of Tesla‘s.

The way I see it, the drive works in a PC, the drive works in a Mac, it just doesn’t work in #CO2Fre. When you’ve tried everything else, the simple answer it so blame Tesla. So, I made a Mobile Service Request and they should be here Friday morning.

Why must Tesla make this so hard!?!?

In any case, unless I find another set of clothes to wear, even without my Dashcam, I shall very much miss cruising on a cloud.

Meetup Online: It’s Okay to Zoom

TimeHorse April 5, 2020 2 Comments

As an Internet Security professional, I have heard some folks expressing dismay over various security issues in the Zoom video conferencing package and the MatterMost chat services. I may do a piece on MatterMost at a later date, but for now I want to focus on Zoom because Zoom is what Meetup is suggesting as one of their preferred video conferencing platforms. (The other, Google Hangouts, is limited to ten people and thus isn’t practical for a number of the meetups I run.)

The thing is, many of the earlier security issues which plagued Zoom at the beginning of the recent surge in online meetings have been solved. Tom’s Hardware wrote a very insightful analysis of these issues in a recent article by Paul Wagenseil, Zoom privacy and security issues: Here’s everything that’s wrong (so far).

Most of the issues covered have already been patched, such as UNC password theft under Microsoft Windows. This was a rather insidious security flaw but fortunately the folks at Zoom stepped up to the plate and patched.

iOS profiling also seems to be fixed. Since I do a lot of my Zoom conferencing, with the National Popular Vote Interstate Compact grassroots coalition, on the iPhone, this has been a great relief. Now, though, I do most of my meetup Zoom conferences on my laptop.

The decrypting of streams at the Zoom servers and re-encrypting them as they go out to the far-end client is at first blush worrisome, but that in part is necessary for folks recording their zoom sessions and though it puts a vulnerability at the level of Zoom staff, one hopes Zoom is careful with whom it employs. But it must be said, nothing I do on Zoom is something I would be embarrassed about were it to leak. I nonetheless want to do everything in my power to make sure it stays secure and I’m happy to hear Zoom is looking into closing this security flaw.

The auto-download for Macintosh is worrisome but again I am happy to say this practice is also ending as it is a backdoor that Zoom can use to allow third party software onto ones Mac. Zoom also has ceased allowing team profiles to share email addresses, though this is not a feature I’m using for any of my Zoom conferences.

As for recording leaking onto the Internet or folks joining your conference uninvited (Zoom Bombing) or war drive scanning Zoom to find your conference, all of these can be solved by user diligence. It’s important to be mindful of who you let into a conference, and don’t let just anyone have access to your recordings. For my Writing Groups, only myself, the account owner, and the persons being reviewed will ever have access to the recordings, and if the reviewed doesn’t need the recordings, we will delete them.

Also, as of this morning, 5 April 2020, at 0:00 UTC, Zoom now requires passwords on all new Zoom events. Thus, even with a Zoom ID scan, you won’t be able to get into the meeting without the password and although the URL can encode the password in an obfuscated way, simply scanning Zoom IDs will not get you into the conferences. And even if you did, I’d still have to approve you. I won’t.

Overall, I’m quite happy with Zoom and hope to use it all through Covidapolis. Overall, I give it this Security Engineers line of approval. And please note, I am available for hire if you like what you see!
