Building secure web apps shouldn't be a burden. We've built a high-assurance web framework at Google that makes security easy for developers. Learn about our "Secure by Design" approach and how it works in our new blog post: bughunters.google.com/blog/6644316... cc: @ddworken.bsky.social

Handling Cookies is a Minefield: Inconsistencies in the HTTP cookie specification and its implementations have caused a situation where countless websites (including Facebook, Netflix, Okta, WhatsApp, Apple, etc.) are one small mistake away from locking their users out. grayduck.mn/2024/11/21/h...
Congratulations, this is amazing! Since you asked, our Google CSP/Reporting API collector currently processes ~3.5B reports per day. That's for CSP, COOP, Trusted Types, and custom reporting. It has enabled us to truly scale up deployment of web platform security features across Google in a safe way
Over the last 24 hours, report-uri.com has processed more than 1,000,000,000 pieces of telemetry! This gives us a unique view of JavaScript behaviour across the Web, as observed by over 15,000,000 unique browsers around the World. Talk about Threat Intelligence capabilities!

It took me twelve years (!) to build up my audience on Twitter. It took 5 days to surpass the 50% point of my Twitter following on Bluesky. I’m hopeful that the overall growth on this site will negate the need to go on Twitter altogether. Sad to see what it devolved into, but thrilled to see it die.

Signature-based SRI is being spec'd right now: wicg.github.io/signature-ba... This will be useful for many use case and become relevant for PCIv4 compliance which requires assuring the integrity of sourced scripts (6.4.3). Please chime in and share your use cases: github.com/WICG/signatu...
also please join me in thanking @mikewe.st, @ddworken.bsky.social and @yoav.ws for pushing this forward!
Web security starter pack is in good shape now and includes many amazing folks passionate about web security like @terjanq.bsky.social and @shehackspurple.bsky.social: go.bsky.app/Uf8dZhz Please share and recommend folks passionate about web security so we can get this community started here 🙂

Excited to share our latest blog post on memory safety! We’re tackling spatial safety in our massing C++ codebase by hardening live++ by default. It adds bounds checks to things like std::vector, preventing a fair bit of out-of-bounds vulnerabilities: security.googleblog.com/2024/11/retr...
