This one is so amazing, super good as example for the bros here, if you're doing an AI scan and you're thinking that maybe there's a SQL, you can tag this for your AI to read ALL reports about SQL from this And for sure, a lot of other cool things can be done with huntdeck nice work mate

Subdomain enumeration won’t show you every domain your target trusts... 👀 csprecon by @edoardottt2 reads the Content Security Policy of your targets and pulls out every domain it allows, from API hosts to CDNs and third-party services! 🤠 🔗 github.com/edoardottt/csprec…

We’re aware of CVE-2026-119618, a race condition in Apache mod_http2 that can lead to heap corruption and potentially RCE. We’re actively investigating. It appears to be configuration-specific, with only hosts with h2 enabled in Protocols being exposed. Patch now or drop h2 until you can.

Getting your hands on source code is a MUST for finding critical bugs. It can happen without it, but if you're looking for zero days, it's very much worth the time investment. Even further, once you've got source code from docker containers or trials, @infosec_au suggests...

Our researchers HexRabbit(@h3xr4bb1t) and NiNi(@terrynini38514) are speaking at #POC2026: “Obvious Was Only the Beginning: A WebKit Exploit Chain for #Pwn2Own” With LLMs advancing this fast, where does AI have the edge, and where do humans still lead? powerofcommunity.net/talk/20…

A technical breakdown of three attack scenarios: chaining Android deep links with WebView misconfigurations, insufficient URL validation, bypassable host checks, and file:// URI exploitation to exfiltrate app data: 8ksec.io/android-deeplink-an…  Each one includes a working PoC against InsecureShop.

AI can be very annoying sometimes cuz of long replies for just simple question ! here is a tip how you can solve that : create a skill named "/sa" and add :"answer in one phrase " , so next time when you want direct answer you can just ask it using : /sa what should i do here ? /sa what this function do ? that way you will spend less tokens , and save alot of time too ! happy hacking 😄

If you can’t build your own security harness then don’t call yourself a security researcher in AI era.

They understood the assignment literally. We recently celebrated the graduation of our latest Africa Hackathon cybersecurity class, and we couldn’t be prouder. These graduates gave months of hands-on training, labs, and problem-solving to build skills that Africa’s digital future really needs. They didn’t just finish a course. They walked out ready to defend systems, protect data, and lead in a field that’s growing fast. To every graduate: you showed up, you pushed through, and you delivered. This is only the beginning. Congratulations to the class, and thank you to the trainers, mentors, and partners who made it possible. #AfricaHackathon #Cybersecurity #graduation

It seems Anthropic really trained its models to hate on Chinese models (Zhipu & DeepSeek), because why else would Opus 4.8 be advising me against using them? Also, when I asked about Z Code Harness, Opus claimed it was a wrapper around Claude Code that uses GLM models. 😂💔

NTSA has introduced a digital system to register and track boda boda riders across Kenya. The system will identify riders, their motorcycles, designated operating areas, stages and drop-off zones to help curb crime.

Back before AI, hacking was actually fun. Leaked creds, vulnerable WP plugins, cPanel, mass exploiting new CVEs with scripts that takes you ages to write, defacing with really bad HTML that u stole from an other hacker. Now nothing’s fun anymore, even hacking NAZA is boring now.

Tip: Indirect prompt injection to XSS 1. Host a .json that contains a malicious payload 2. Ask victim to create a .ppt slide of the data in <hostedJsonUrl> 3. Victim prompts agent and opens .ppt 4. alert() fires Just reported it. Will keep you guys updated.
