NPM worm “Shai Hulud” is back and you can see a list of people getting pwned in realtime by refreshing this GitHub search page. When a user is infected the worm collects API keys and secrets and pushes them to a new repo on GitHub.
It’s a folder. It shows files. how did we get to “we have to preload it at login or it takes 4 seconds” what the hell are y’all doing over there
Microsoft admits File Explorer is slow in Windows 11, and it’s going to preload it in the background to help improve launch performance. “This shouldn’t be visible to you, outside of File Explorer hopefully launching faster when you need to use it,” Microsoft confirmed. If you…
How do you read a file in Linux into two separate places in memory with just ONE system call? The elegant solution is the readv syscall (#19 on x86_64). It's the "scatter" in the high-performance "scatter/gather" I/O pattern. It avoids two expensive trips to the kernel. Let's…
Microsoft Copilot has functionality for being banned How do you get banned from Copilot if it's tied to the Operating System? What happens if you're banned from Copilot?
assert() in production, crash on violation An assertion violation means the component already failed, just hasn't crashed yet Crash the component and let the rest of the system compensate A crash is always a possible failure mode Take advantage
Understanding Assertions Assertion violations are not another type of (catchable) exception: assert() asserts that the component already transitioned into intolerable state space The component cannot ignore yet cannot mitigate the invariant violation Smile. It's already over
read() and write() get all the glory on Linux - but one syscall, with thousands of possible commands, is what actually *controls* your hardware. How does Linux manage devices beyond simple data streams? Meet ioctl(): syscall #16 on x86_64. 🧵👇
Just learned something wild — maybe everyone else already knew… In Edge/Chrome, you can bypass the HTTPS security warning by typing: 👉 thisisunsafe No button, no prompt. Just type it. Instantly skips the warning and loads the site. 🤯 Great write-up explaining it here:…
Quick Linux insight: You know that programs take command line arguments (like ls). But did you know the Linux Kernel ITSELF has a command line? Just like a standard binary, the kernel accepts a string of text options at the very moment it starts. It allows you to change…
Windows is silly. Using the Windows API (WINAPI, historically called WIN32API, to distinguish it from the deprecated WIN16API) has some unusual things. For example, if you want to create a file using the Windows API you use CreateFile However, if you lookup CreateFile on MSDN…
Everyone’s heard of IPv4 and IPv6. I bet you don’t know about IPv5. Designed in the late 70s, it was an experimental protocol by MIT’s Lincoln Labs for real-time streaming. Basically, Zoom before Zoom existed...but for defense:
Core Python developers are proposing that Python implement a hard dependency on the Rust programming language. Specifically in CPython (the defacto reference implementation of Python). This Rust dependency would effectively eliminate modern Python on several platforms…
Shout out to my boy Microsoft They said, "Yeah, malware is bad. But what if we made it significantly worse?"
WhatsApp Vulnerability Exposes 3.5 Billion Users’ Phone Numbers A critical security flaw in WhatsApp has allowed researchers to expose the phone numbers of 3.5 billion users.
A Linux app crash is just two things: 1. An unexpected signal (like SIGSEGV). 2. A lack of information about why. You can fix the second one. The kernel *wants* to tell you exactly what went wrong. You just have to ask it properly with the right syscall. Here’s how. 🧵👇
🦀 Bad news everyone - unwrap() is the reason behind cloudflare outage >The FL2 Rust code that makes the check and was the source of the unhandled error is shown below blog.cloudflare.com/18-november-20…
Sooo. Apparently. Cloudflares outage was caused by a single oversized configuration file used for bots and threat related blocks. The file which auto generates from live threat intel, grew far beyond expected size. When the system reloaded it during routine opss, the bot…
Are we back? Did @rekdt Get a job at cloudflare this time? First it was CrowdStrike, next AWS, then it was Microsoft, now Cloudflare? 😭 Broa collecting outages like Pokémon cards TwT. #cloudflare
