"Zombie ZIP" CVE-2026-0866 is not really a vulnerability which can evade AV engines, because the resulting ZIP file cannot be opened by normal tools, it's malformed.
It's more like a steganography/obfuscation trick, you need malicious code already running to extract the payload.

Look Ma, no sensors!

Look Ma, no sensors!

"How does it even work?"
The question that keeps hackers' hearts pumping, blood pressure rising, and curiosity growing.
This is Damien Cauquil's reverse engineering journey into a cheap smartwatch that measures at least one of those.

RE//verse 2026 - Reverse Engineering Conference Join us March 5-7, 2026 in Orlando, FL. Premier reverse engineering, vulnerability research, and malware analysis conference with world-class trainings and talks.

It was well organized, highly caring staff, not to mention the food was really good!

Just to be clear, I’m not affiliated at all; this is genuinely my honest opinion.



If you’re interested in reverse engineering at all, RE//Verse is quickly becoming the top conference!

Diagram titled “Transformer attention.” It shows three steps of the attention computation with code snippets beside each step. The first step is “Scale factor 1/√dₖ,” highlighting code that computes the reciprocal square root. The second step is “Dot product Q · K,” showing code performing a dot-product accumulation. The third step is “Scaling + max tracking,” highlighting code that multiplies by the scale factor, stores the value, and updates a running maximum. The phrase “Transformer attention” appears prominently in the center.

Simple age check for Linux:

Just have the shell ask the user to check the host IP on first boot.

If they type ifconfig they are old enough, if they type ip addr they deserve to be restricted from their computer 😇

AirSnitch: Breaking Wi-Fi Client Isolation: Technique Index, Tool Usage & Defenses This morning I came across another interesting paper submitted at the NDSS Symposium 2026 like the BLERP paper already documented in this forum, but this time challenging the Wi-Fi client isolation th...

Think your guest Wi-Fi is isolated from your main network? Think again.
AirSnitch (NDSS'26) breaks client isolation on every router tested: from home APs to enterprise WPA2/3-Enterprise. Full MitM in seconds, sometimes leaking WPA2 traffic in plaintext: 🔗 community.penthertz.com/t/airsnitch-...

We found that Wi-Fi client isolation can often be bypassed. This allows an attacker who can connect to a network, either as a malicious insider or by connecting to a co-located open network, to attack others.
