Why should malware repos be deleted? Serious question. The repos aren't themselves doing harm, are valuable for research, and would be distributed some other way if GH removed them. Maybe a banner “be careful! others have reported that this repo may not do what it claims. proceed with caution” would be a more appropriate response?

They're just as useful for research as the spam/scam comments you occasionally see at the bottom of an HN thread.

Earlier quoted context omitted.

As another data point: MSFT have some sort of open mail server/service called onmicrosoft.com which (in my experience anyway) is only being used to send out fraudulent paypal messages. Because it lets the spammer set the From to service@paypal.com and also contains valid DKIM etc, it sails past spam filtering. There are so many complaints about this on (real) paypal.com forums, but Microsoft are apparently unable to…

How would Microsoft forge a DKIM signature? It sounds more likely that it's just a shitty email from Paypal.

I saw one of these emails too. It was sent by an onmicrosoft.com server, linked to a phishing site, but passed SPF/DKIM/DMARC for Paypal.

Microsoft obviously isn't "forging" it. It's valid: https://labs.guard.io/echospoofing-a-massive-phishing-campai...

These repos are targeting kids. They should be removed or at least disabled.

Fun fact: if you come across one of these discord webhooks you can delete them. Just curl -X DELETE https://discord.com/api/webhooks/ [...]

I'm not familiar with the context here, could you please elaborate? If I understood correctly, any unauthenticated user can delete the webhook? I can currently find hundreds of matches for that on Github, anyone could just go and delete them all?

Yep, anyone can delete a Discord webhook if they have the URL.

All you do is send a DELETE request to the URL.

I use (redacted).on Microsoft.com tenant which is free of cost to me as a sandbox to learn about office 365 admin stuff. I don't work on it every day but it is nice to have this sandbox. I don't send spam or phishing emails. I don't send emails from this tenant at all to others, only to my own email addresses or to people I know for testing purposes.

I think Microsoft has a general problem with getting rid of unwanted things within their eco-system. I keep complaining that their feedback.azure.com portal is filled with spam/malware comments and links, but even internally their teams can't reach anyone to get it fixed. Example https://feedback.azure.com/d365community/idea/9d0b22d8-c025-...

I think I read somewhere that scammers set up an email distribution list / alias / forwarding from one something.onmicrosoft.com account to dozens of victims, and then they trigger a (real!) paypal email with that one something.onmicrosoft.com address as the recipient. So the email has a valid DKIM signature from paypal, then microsoft forwards that email to all the victims, which will still pass DKIM while amplifying the attack (and maybe boosted by microsoft's SPF reputation as well) to hit as many people as possible. Apparently the paypal emails are real but dangerous as they will allow the attacker to somehow take over the victim's account if they log in, as the "middleman" onmicrosoft.com alias then becomes associated with the account which was the original "to"-email from paypal. Something like that, at least.

If you've identified GitHub repositories hosting malware, you can report them directly to GitHub via their Abuse Report page, providing links and any relevant details. GitHub typically removes repositories that violate their Acceptable Use Policy, but response times may vary. If the malware is actively being used for harm, you may also consider reporting it to security organizations or CERT teams.

I may have missed the part where the author reported these to github but they're not going to be removed it nobody actually reports them. What a lot of effort put in to seemingly give up at a crucial final step.

At the same time they suspended my GitHub account which I had for more than a decade, maintained multiple big open source projects, and contributed in hundreds. Didn't even bother to provide any reason or reply to any of my requests. Worst experience of any IT service I had. I would never recommend using GitHub to anyone, and started donations to Codeberg and Forgejo.
