Huawei watch gt reverse engineer and custom firmware

Hi, i got a huawei watch gt a few weeks ago and i like its design , but i feel like huawei coud improve it by adding more features on the firmware (but it didnt want) , so i want to put my programming and reverse engieneering skills and make that myself, but i want to know if anyone did that (or if anyone knows anything how can i dump , mod and flash it to the "smartwatch").

hacking: security in practice
Cyber Reasoning System for final college project

Hello fellow hacking enthusiasts!

I'm a CS student in my final year and I've decided to create a cyber reasoning system for my final year project. The problem is that I searched for the topic but there is not much source material on this type of projects. The only relevant thing I found is this repository:
https://github.com/mechaphish
But there is not much documentation of the inner workings of such a system and I do not want to copy paste it. I just want to understand the core architecture and some explanations for some methods.

Of course, considering the time frame for the project, I will build a much simpler CRS which will only take linux binaries and find some specific vulnerabilities.
So do you people know some good sources for this type of project? Thank you!

log4j-scan - A fully automated, accurate, and extensive scanner for finding vulnerable log4j hosts
http://www.kitploit.com/2021/12/log4j-scan-fully-automated-accurate-and.html

A fully automated, accurate, and extensive scanner for finding vulnerable (https://www.kitploit.com/search/label/Vulnerable) log4j hostsFeaturesSupport for lists of URLs.Fuzzing for more than 60 HTTP request headers (not only 3-4 headers as previously seen tools).Fuzzing for HTTP POST Data parameters.Fuzzing for JSON data parameters.Supports DNS callback for vulnerability (https://www.kitploit.com/search/label/Vulnerability) discovery (https://www.kitploit.com/search/label/Discovery) and validation.WAF Bypass payloads.
AnnouncementThere is a patch bypass on Log4J v2.15.0 that allows a full RCE. FullHunt added community support for log4j-scan to reliably detect CVE-2021-45046. If you're having difficulty discovering and scanning your infrastructure (https://www.kitploit.com/search/label/Infrastructure) at scale or keeping up with the Log4J threat, please get in touch at (team@fullhunt.io (mailto:team@fullhunt.io)).

 DescriptionWe have been researching the Log4J RCE (CVE-2021-44228) since it was released, and we worked in preventing this vulnerability with our customers. We are open-sourcing an open detection and scanning tool for discovering and fuzzing for Log4J RCE CVE-2021-44228 vulnerability. This shall be used by security teams to scan their infrastructure for Log4J RCE, and also test for WAF bypasses that can result in achiving code execution on the organization's environment.It supports DNS OOB callbacks out of the box, there is no need to setup a DNS callback server.UsageManagement Platform.
