I think it’s hilarious that I now have my first CVE because I got annoyed with an unresponsive vendor and just posted the zero day exploit I was trying to report to them on my GitHub πŸ˜†

NVD - CVE-2026-49494

ComoDoS - Exploiting a Remote Kernel Zero-Day Vulnerability in Comodo Internet Security

It's been a while since I did a vulnerability research article. How about a little DoS zero-day as a treat?

Sometimes firewall stops attackers, sometimes attackers stop firewall. analyzing a zero-day vulnerability in Comodo Internet Security's Firewall driver.

My thoughts on Microsoft's threat to prosecute researchers for dropping zero day exploits

Slowly setting up my video/livestream studio again. The amount of tech required for even a half decent experience is crazy
Try out the early alpha of Process Isolation in Chrome 138. chrome://flags/#enable-process-isolation-ui then chrome://settings/system for the switch. Read known issues https://issues.chromium.org/issues?q=hotlistid:8036290%20status:open and report bugs! Especially interested in App-Compat bugs.

I found a zero day in a security vendor's firewall software that allows you to remotely crash the entire system by sending it a single malicious packet. Since the firewall is responsible for inspecting traffic prior to the operating system handling it, no ports even need to be open for it to work.

Listening to cybersecurity people freak out over Mythos is so tiring. Like, bro, your local water treatment plant runs Windows XP, your mobile provider's hardware is older than you are, and the protocol that routes internet traffic is secured by everyone just agreeing that hijacking it would be uncool.

I spent nearly 4 months investigating the inner workings of a North Korean state-sponsored hacking group. Here's what I found:

- The group used generative AI tools to aid in almost every part of their operations.

- They exfiltrated 26,584 cryptocurrency wallets from victim systems, with a combined value totaling as much $12 million dollars.

- In several cases, the threat actors set up entire front companies to lure in developers via fake job posting, then infected them with malware.

- The threat actors successfully pulled off a supply-chain attack by compromising a VS Code extension developer's system.
