Email Registration Vulnerabilities and IPv6 Scanning Challenges

Themes covered in this episode

Edge cases at scale still matter

Works from this theme exploit rarely-occurring issues, but with an internet-wide aperture to end up with impressive results. Look for: mechanising bit-squatting; static code analysis for vulnerabilities across all browser extensions, or across web ecosystems; and how Let’s Encrypt worries about revoking and reissuing 400M certificates in a week.

Going above and beyond

Talks and papers often use state-of-the-art tooling to measure/detect an interesting phenomenon. This theme highlights four works that could have followed that path, but also built robust tooling/research data to help others push the state-of-the-art forward. Look for: large scale collection and remediation of dangling domains and static secret leaks, preventing memory-corruption vulnerabilities across the Android ecosystem, remote timing attack frameworks, and SSH testing at scale.

What goes on behind the curtain can be dangerous

Modern IT systems are composed of many layers. Usually the details at lower levels can be abstracted and safely put out of mind. This theme highlights work that shows that what happens in these oft-ignored places can have significant impacts. See: AWS-internal resources built on your behalf, BGP security weaknesses, stealthy hardware backdoors in access control systems spanning over 15 years, Wi-Fi management plane vulnerabilities, VPN-OS interactions, and a legacy file-system hack in Windows.

Nifty sundries

As always, we wanted to showcase work that didn’t fit into the major themes of this issue. We cover: bypassing voice authentication with only a picture of the victim’s face, racking up bills on locked credit cards, email parsing confusion, scanning IPv6, and a timing attack on remote web clients.

Conclusions

While we started off 2024 with a modest amount of high-quality works, this has scaled up significantly. As conference publications increase, we do see a slight decline in the number of blogs; there does appear to be some inverse correlation between the two tallies.

We highlighted three themes for this quarter:

1. Rare events that happen at internet-scale have big impacts.
2. Going above and beyond in tooling development.
3. Cross-layer gotchas.

We’re looking forward to seeing how the year closes out with our year in review and the final quarter of 2024.
