On June 11th, 2024, we discovered a set of vulnerabilities in Kia vehicles that allowed remote control over key functions using only a license plate. These attacks could be executed remotely on any hardware-equipped vehicle in about 30 seconds, regardless of whether it had an active Kia Connect subscription.
The issues described in this article were resolved after this article was posted.
For years, the best way to get 10 gigabit networking on laptops was to buy an expensive, large, and hot 10 GbE Thunderbolt adapter. With new RTL8159-based 10G USB 3.2 adapters coming onto the market, the bulky adapters might be a thing of the past. Just look at the size of the thing in comparison to my Thunderbolt…
Apple’s launch of macOS Big Sur was almost immediately followed by server issues which prevented users from running third-party apps on their computers. While a workaround was soon found by people on Twitter, others raised some privacy concerns related to that issue.
In the US, you can get a domain name like `somename.city.state.us` for free. If your town has its own domain, you can get nameservers from Amazon Lightsail, send the *Interim .US Domain Template* to the delegated manager for your locality, then point DNS entries at your webhost.
Motivation For a moderately security conscious geek like myself, there can be a number of reasons to want to set up a home VPN server: Accessing your home computer via screen sharing without exposing it to the Internet (and thereby to potential evil-doers). Accessing servers with IP white lists (common case for…
On 26 Nov 2019 at 14:55 UTC, I logged into my server that hosts my website to perform a simple maintenance activity. Merely three minutes later, at 14:58 UTC, the domain name susam.in used to host this website was transferred to another registrant without any authorisation by me or without any notification sent to me…
I was debugging my WiFi settings this week when I noticed something strange. WiFi Analyzer was showing two hidden networks coming from my router, one for each frequency: 2.4GHz and 5GHz. Networks which I haven't configured and didn't appear in my router's admin interface. WTF?
Update 5/29: Mullvad has begun rolling out a mitigation feature on their servers that scrambles exit IP positions, thereby fixing this issue. IPs are still deterministically selected based on the pubkey. Mullvad is one of the few VPN providers that offers multiple exit IPs for its servers. If two people connect to the…
I have been living in my current apartment for more than a year now and I noticed I have never inspected my router which was provided by my ISP when I moved in. The only thing I changed in router is
Viva.com, one of Europe's largest payment processors, sends verification emails without a Message-ID header — a requirement of RFC 5322 since 2008. Google Workspace rejects them outright. Their support team's response to my detailed bug report: your account has a verified email, so there's no problem.
I've always had a soft spot for this particular car brand. Our family has owned a few of them over the years, and they've served us incredibly well. In 2023, I bought a new four wheel drive/SUV from them, and it was the first time I had
If you spy on an HTTP/2 connection starting up you'll notice that it sends an almost-but-not-quite valid HTTP request at the very start of...
“Bro, ban me at the IP level if you don't like me!”
This blog is reserved for more serious things, and ordinarily I wouldn’t spend time on questions like the above. But much as I’d like to spend my time writing about exciting topics, som…
Late last year, I started experiencing some unusual intermittent connection issues on my Desktop. In general, I had a stable connection with average latency; however, at (seemingly) random times throughout the week, I would start experiencing sudden 2000ms+ latency spikes every couple of seconds.
Over and over again, I’ve seen people fix some wireless-related problem and go “wow, I had no idea how much better this could be!" • Wireless protocols often silently operate in an extremely degraded state that makes them substantially worse than wired equivalents.
This article is part of a series on (European) innovation and capabilities. In a break from the usual GPS/Galileo, DNA and C++ posts, here is a bit on 5G and national security. It turns out that through PowerDNS and its parent company Open-Xchange, we know a lot about how large scale European communication service…
Last November I went to an IETF meeting for the first time. The IETF is an interesting place; it seems to be about 1/3 maintenance grunt wo...
Since I joined Charm, I’ve been working and learning more about SSH, and I thought I would share a few quick tips and tricks with you.
Have you ever tried to download videos from YouTube? I mean manually without relying on software like youtube-dl, yt-dlp or one of “these” websites. It’s much more complicated than you might think.
The Internet is a dangerous place in the best of times. Sometimes Internet engineers find ways to mitigate the worst of these threats, and sometimes they fail. Every now and then, however, a major …
Thanks to war, geopolitics, and climate change, Europe will have more frequent and more severe internet disruptions in the very near future. Governments and businesses need to prepare for catastrophic loss of communications. Unfortunately, the necessary changes are risky and expensive, which means they won’t do it…
Most websites can't tell you about them. But I can.
