I've finally replaced the old-school #CAPTCHA required to sign up on https://cvecrowd.com with an open-source, #privacy preserving, #accessible, and globally compliant alternative: #ALTCHA
It relies on proof of work and I am super hyped to see whether it will prevent #bots from signing up. I'll keep you updated :)

I've blocked two BlueSky accounts from https://cvecrowd.com:
- kriptabiz.bsky.social
- qiancx.bsky.social
Both were posting slop about a bunch of current vulnerabilities. The URLs in their posts lead to suspiciously similar pages (see screenshot).
I assume it's pure coincidence that both pages have the same Google AdSense ID in their HTML 😅

By the way, the reason why I used object tags instead of image tags is that I can load a fallback *image*, not just alt text, if the original avatar cannot be loaded.
pymobiledevice3 webinspector js_shell was very helpful for debugging, as its output immediately pushed me in the right direction:
webinspector.console[232959] ERROR Refused to load https://media.infosec.exchange/infosec.exchange/accounts/a…
Apparently #Safari on #iOS applies img-src directives of the content security policy to *object tags* that load images like so: <object type="image/png" data="https://media.infosec.exchange/infosec.exchange/accounts/avatars/109/551/708/143…
Anyone else having the issue that avatars on https://cvecrowd.com are not loading on a mobile device?

About
I'm a hacker and mainly post about web security.
By profession, I am a pentester and team leader @usdAG.
I like to explain and understand things and I am convinced that the two go hand in hand.
So my posts are mostly of an educational nature.
Lately, I spend most of my free time developing CVE Crowd.
