I'll be speaking at BSides Canberra: cfp.bsidescbr.com.au/bsides-canberr… -- this will cover my recent find of an RCE in Git (dgl.cx/2025/07/git-cl…) and how that and some other vulnerabilities could be used against developers.
New blog post: Ghostty 1.0.0 terminal security; dgl.cx/2024/12/ghostt… (CVE-2024-56803)
Latest write up from @davidgl detailing his research into terminal escapes and the 10 ‼️ @NISTcyber CVEs that had potential for remote code execution. @defcon @MSFTBlueHat @_everythingopen @linuxaustralia @linuxfoundation #opensource #cybersecurity gresearch.com/blog/article/g…
For once a non-security terminal thing. I'm sure someone else has written this but I couldn't find it; here's a simple script that makes commit IDs in "git log" clickable (in many terminals): gist.github.com/dgl/ef848e75c0…
Thank you to everyone who attended my @_everythingopen talk, with more of my terminal research. I've published the Docker image PoC that I demoed, see infosec.exchange/@dgl/110019782…
Security tip for those about to appear on TV goo.gl/7YT1f
@turmoni let me know if you go for drinks after or something, I might be around.
@tarasyoung some irony in going to that URL and be told I need to upgrade Flash. Yes computers are continuing to ruin my life.
Wondering why twitter won't let me have a https:// url as my home page..
