Wonderful day!

Depending on the anti-malware, it may be either a known signature, or heuristics.
- In case of the former, the signature may be a just a single use of function inside the safe program that matches with a malware that uses the same (e.g., in a thread or memory range the anti-malware probed);
- Heuristics - May just be too restrictive local security settings;

Yet, if you don’t have enough time to investigate in locally in isolated environments as virtual machines/containers, debugging syscalls and activities in file-system, memory, network etc., there are less manual or outsources, options, including the common know ones:
- opentip.kaspersky.com
- opentip.kaspersky.com/requests
- virustotal.com/gui/
- any.run

Please stay safe!

Sincere apologies for the person condition…

As you provided no actual points to consider important to invest much time into the answer, let’s make it quick, too.

It’s not illegal to be a hacker. It’s illegal to illegal actions via hacking. There are two common ways to distinguish hacker’s scopes of actions: 1) team colors; 2) hat colors.

The concept of red teaming and blue teaming emerged in the early 1960s.

A white hat hacker breaks security for non-malicious reasons…
A black hat hacker is a hacker who “violates computer security for little reason beyond maliciousness or for personal gain”…
A grey hat hacker lies between a black hat and a white hat hacker, hacking for ideological reasons… Source: https://en.wikipedia.org/wiki/Security_hacker#Classifications

It’s impossible to “quickly” learn to be a hacker. The security subjects shift each fraction of a second, and you have to train your intuition layering it on the experience you gain from theories and practice.

Some of known ways to get in-depth are:

1. Public Capture-the-Flag (CTF) events as you may find at: https://defcon.org/html/links/dc-ctf.html;
2. Bounties, like: https://www.hackerone.com/bug-bounty-programs;
3. Serious contribution to open-source projects (e.g., KDE, Mozilla, programming language compilers as C++, Rust);
4. Contributions to dirvers/middlewares, and databases as: https://www.aircrack-ng.org/;
5. Contributions to exploits databases as: https://www.metasploit.com/contribute, https://www.exploit-db.com/;
6. Contributions to CVEs as: https://www.cve.org/ReportRequest/ReportRequestForNonCNAs;

There are relatively not serious but still options as: https://tryhackme.com/

In other words, you just find your love in the security subjects you consider closer to the heart, and go in deeper…
Then, you just use the tools you want to achieve the requirements:

# Let's just use the lovely Bash v5+ to get our IP addresses (no cURL etc.).
exec 3<>'/dev/tcp/ipinfo.io/80';
printf 'GET /ip HTTP/1.0\r\nHost:ipinfo.io\r\n\r\n' >&3;
while read -r l || (( ${#l} )); do [[ $l =~ ^([0-9]{1,3}\.){3}[0-9]{1,3}$ ]] && printf '%s\n' "$l"; done <&3;

Yet, please do consider that actual hackers do never expose their actual identities. Since, your identity is a single and permanent key to your life and your family…
Once you’re in, and you become responsible for your actions, you become a loner, and not a single soul will ever support you in the end.

The quieter you are, the more you are able to hear.

As mentioned, I am sorry, but I am not the author. Raju Gandhi is.
It should be possible to contact him if required:

Raju has been writing software for over two decades. He’s a software developer, architect, consultant, author of multiple books, teacher, and a regularly invited speaker at conferences around the world.

That’s a beautiful, lovely name, indeed! ✨
Yet, I was born in Vilnius, Lithuania.

Funny or not, but the author is a miracle. Their attitude to the book, family, travel, and overall passion is another marvel, too.
The book is also attributed to his mother.

Writing a book is often viewed as a solitary activity. But no one is an island. I can only aspire to personify the values imparted upon me by my family, teachers, and mentors. My work is built on the shoulders of giants - technologists from the past and present who worked, and continue to work, tirelessly to make the world a better place. You may see my name on the cover, but a lot of the credit for this book goes to these individuals…

The countless individuals who contribute to Git, and those who enrich the ecosystem around Git by writing detailed technical blog posts, creating informative videos, and answering questions on Stack Overflow - I am humbled by your work, and I hope that this book will be a valuable addition to your valiant efforts. Thank you.

My eternally patient, much better half, Michelle, who shouldered everything that needed to be done so I could focus on this book. Several of the narratives in this book come from her creative mind. I love you.
My family and my sisters, who (despite their fervent denials) forged me into the individual I am. And finally, you, the readers. Your attention is a scarce resource, and I deeply appreciate the time you’ll spend with this book. Happy learning.

Now go on, Git!

~ “Head First Git: A Learner’s Guide to Understanding Git from the Inside Out” by Raju Gandhi [ISBN: 978-1-492-09251-3]

Gitea is awesomly similar to GitHub, GitLab, Codeberg, an many others, yet everything of these - is not Git. Git is a whole Universe started by Linus Torvalds, and now supported by marvelous Communities.

Gitea is a same service, as the aforementioned, for a remote, authorized, and safer Git, and other features as: Repository optimizations and analysis; Issue tracking; Discussions; Automation as Action Workflows etc.

Git Large File Storage (LFS) is normally used for data over 20-100 MB, and it is not directly related, nor officially maintained by Git.

Please do not store in Git pure binary or media files over 10 MB. Otherwise, your remote and local Git may struggle every change processing comparing bit-by-bit, instead of its hashsum.

One of the book to seriously start with Git I would recommend, in addition to its official documentations and Man files:
- Head First Git by Raju Gandhi.

To help decide if Gitea is suited for your needs, here is how it compares to other Git self hosted options.

I am sorry, but what do you mean by “work”? There’s a whole documentation out there, just in case:
- https://docs.gitea.com/category/usage

The great project that have been out there for years…
And I’ve no idea why some just still ask without a single personal research, sorry… There’s so just much awesome information about such projects… if you just make a little search…

Yes, they oriented their design on GitHub, including the Act Runner Yaml configuration based on Nekto’s work.

The goal of this project is to provide the easiest, fastest, and most painless way of setting up a self-hosted Git service.

Gitea is incredibly freaking awesome for personal, safe, Git service, too, with even Action runner workflows. The standard Git, HTTPS, and SSH protocols are supported.
You may just self-host it on a host (or more isolated) by building/downloading the single binary/container for your host and launch it. Yes, the whole marvel is a single Go binary.

There are numerous people who work on the project right now:

With their license change, Forgejo fork happened.

Oh! I see! Just in case, Traefik has great options for debugging, and logging (e.g. TRACE log level)! Not to mention custom plugins! There’s a great Discourse based forum, and there’s both IRC and Discord Communities, too!

For the reverse proxy you may find Traefik marvelous, in case if Nginx/HAproxy is too featureful.
