When applying for a job at McDonald's, over 90% of franchises use "Olivia," an AI-powered chatbot. We (@iangcarroll and I) discovered a vulnerability that could allow an attacker to access the over 64 million chat records using the password "123456". ian.sh/mcdonalds

Hey peeps! As many of you know, I was diagnosed with ALS nearly 2 years ago. I continue to fight a losing battle with it every day. I am determined to live long enough to attend this ALS Walk fundraiser in October. I would sincerely appreciate any small donation you can spare to…

I made a tool to help test archive (zip/tar) extraction bugs (synk working directory into archive, add path traversals, links, permissions, etc): github.com/avlidienbrunn/…
MITRE’s CVE funding just dried up because the US can’t get its paperwork in order. Maybe global cybersecurity shouldn’t depend on one country’s clown show. Just a thought.
