- Web3 developer Brian Guan lost $40,000 after accidentally posting his wallet’s secret keys publicly on GitHub, with the funds being drained in just two minutes.
- The crypto community’s reactions were mixed, with some offering support and others mocking Guan’s previous comments about developers using AI tools like ChatGPT for coding.
- This incident highlights ongoing debates about security practices and the role of AI in software development within the crypto community.
If you have your secret keys in your repository you’ve already fucked up, long before you accidentally make that repository public.
One of the first things you should do in a repo is add a .gitignore file and make sure there are rules to ignore things like
*secret*or*private*etc. Also, I pretty much never usegit add .because I don’t like the laziness of it and EVERY TIME one of my coworkers checked in secrets they were using that command.Even though that’s a good extra precaution, per person config data, such as keys, should be stored outside of the repo, eg. in the parent directory or better in the users home dir. There is zero reason to have it in the repo. Even if you use a VM/containers, you can add the config in an extra mount/share.
I basically always do a
git add -pVery useful command and it works with other git commands as well.
Everytime a colleague asks me for help with git that’s the one rule I suggest them to use.
What does that do?
Instead of just adding whole changed files, it starts an interactive mode where it shows every hunk of diffs one by one, and asks you to input yes or no for each change. Very helpful for doing your own mini code review or sanity check before you even commit.
That’s exactly why I do it
The
soption is very useful to split the chunks.And that’s why you always
leave a noterecheck your .gitignore file before committingDoes Microsoft’s GitHub offer any pre-receive hook configuration to reject commits pushed that contain private keys? Surely that would be a better feature to opt all users into rather than Windows Copilot.
they notify but that’s all
They notify but iirc only if you push a commit to a public repo. The dev in the article pushed it to a private repo, then later made the repo public.
I use this as a pre-commit hook https://github.com/americanexpress/earlybird
Ehhh. I mean, I have local repositories that contain things that I wouldn’t want to share with the world. Using git to manage files isn’t equivalent to wanting to publish publicly on github.
I could imagine ways that private information could leak. Like, okay, say you have some local project, and you’re committing notes in a text file to the project. It’s local, so you don’t need to sanitize it, can put any related information into the notes. Or maybe you have a utility script that does some multi-machine build, has credentials embedded in it. But then over time, you clean the thing up for release and forget that the material is in the git history, and ten years later, do an open-source release or something.
I do kind of think that there’s an argument that someone should make a “lint”-type script to automatically run on GitHub pushes to try and sanity-check and maybe warn about someone pushing out material that maybe they don’t want to be pushing to the world. It’ll never be a 100% solution, but it could maybe catch some portion of leakage.
Users often don’t take care to separate private and public environments. They just dump all their stuff into one and expect their brain to make the correct decision all the time.
Put your private data into a private space. Never put private data into a mixed use space or a public space.
e.g. Don’t use your personal email at work. Don’t use your personal phone for business. Don’t put your passwords or crypto keys in the same github or gitlab account or even instance and don’t reuse passwords and keys, etc.
Sure, but nothing I said conflicts with that.
I’m talking about a situation where someone has a private repository, and then one day down the line decide that they want to transition it to a public repository.
You’re not creating the repository with the intention that it is public, nor intending to mix information that should be public and private together.
Having plain text secrets, or having secrets at all in a repository is always a bad practice. Even if it’s a super-duper private/local/no one will ever see this repo.
That’s exactly what pre-commit.com project is doing
