Zooming way out (perhaps to the point of useless observation), it's a pity that the web embedded VSCode editor is signed into GitHub at all. Defense-in-depth or not, a huge vulnerability surface arises from that original sin. It'd be like if you had a god-permissioned GitHub API token stored in world-readable plaintext on your workstation for the malicious-NPM-package-of-the-week to find.
In a perfect world, it'd be awesome if the in-browser IDE launched with a temporary per-repo permission scope or token that allowed only pull and push to the repo in question; no github.com web session whatsoever. If you want the full GitHub web UI experience, well .... go back to github.com; make github.dev a single-repo service.
I'm assuming that's a) inconvenient for users, b) hard to implement, and c) a historical assumption baked into a lot of the github.dev tooling, though. Ah well.
That's actually exactly what they do for codespaces. The token only has read/write on the repo you activated for the codespace [1]. They should definitely consider doing that for github.dev as well.

How about pull from the repo but only push to a staging area from which the user, but not the token, can push for real?
Frankly, LLM agents should do this too. Letting your LLM push seems foolhardy to me.
I have been thinking more and more about how I might use this pattern.
But then someone else on the team should have to manually approve that MR to allow it to be merged to main.
This kind of defeats the ability of malware to push stuff out automatically.
github token got stolen and also cloudflare tokens
guys even if you take security seriously you are going to get hit on a long enough time frame
best thing to do is segregate and control damage
trust no one, nothing, use orbstack, and always operate under the assumption that your token is going to get leaked at some point
it knocked off my entire momentum. fortunately seemed like it was just a spam bot that took my tokens and created bunch of fake spam pages and trying to mine crypto
the biggest feeling is the one of feeling violated
take care fellow travelers
> created bunch of fake spam pages and trying to mine crypto
saw a weird spam site, so damn tired went to bed thinking it was some mislick on my side
woke up next morning and loaded up my domain, it redirected and panic set in
my SEO is probably nuked even though it has been under 24 hours
Classic MSRC. It has figured out that researchers will report for free regardless. Why change?
I don’t know the specifics of this case, but I’ve managed bug bounty programs in the past through Bountysource and HackerOne. One thing that occasionally happens is that a report makes its way to the development team before the security team has fully assessed it, in this case MSRC.
At that point, a developer may decide to quietly fix the issue. Sometimes that’s driven by a concern, rational or not, that being associated with a security bug could reflect poorly on them or affect future promotion opportunities. The result is that by the time the security team attempts to reproduce the report, the vulnerability is already gone.
From MSRC’s perspective, all they see is that the provided reproduction steps no longer work. They have no visibility into the internal history of the bug or whether someone already patched it. As a result, the report gets closed as invalid even though the original finding may have been legitimate.
This is laziness, security absolutely could verify these steps.
I'm catching up on the infosec twitter side but it seems like it was even worse. A lot of people have the same story as me in 2023 of "they silently patch the bug and don't even credit you" which really stinks.
I hope you get credit where credit is due in future endeavors.
I have no interest in selling these vulnerabilities or sitting on them. At the same time, it feels really bad to have a vendor disrespect the hours it can take to make a proof-of-concept by just patching it silently and not crediting you or acknowledging it.
The author said:
You cannot just use the shortcut trick to install the evil extension directly because of new publisher trust system;
You can bypass this by using local workspace extensions which has no publisher screening, but CSP blocks it;
The solution seems to be that installing a local workspace extension which binds a shortcut of 'install extension without checking publisher'.
So I assume it means:
1. you need two extensions, 1st one is local and only for the keybinding, and 2nd one is the 'real' evil one and it doesn't need to (actually can't, because of CSP) be local anymore?
2. the CSP only prevents the JS in local extension but nothing about its package.json (or the ability to add shortcuts), right?
We can try to just put a `my-extension/extension.js` for the most direct execution but the CSP blocks that. It's only a script-src CSP blocking it though, so fetching the package.json is still kosher. So we end up using it to contribute a keybinding instead.
There are probably better sources but I think this video by The Primeagen is a good introduction.
Github creds or the computer, can't decide which one is worse.
Someone is going to be blacklisted by Microsoft.
