Exploiting NGINXDay2022 Blog Post and Slides following my talk at @_dc151 😁 grimhacker.com/2022/05/22/ngi…
Thanks for some great and engaging talks tonight from @grimhacker and @danielperezcas8 !!! Lovely to see a good turnout too and see you all next month!
Second up @danielperezcas8 on the topic of 🎣ing!
First up is @grimhacker with “NginxDay2022” - covering the recent Nginx auth ldap vulnerability; and discovery & exploitation thereof We then have @danielperezcas8 with “Internal phishing with Microsoft 365 Defender, and how catch some credentials"
not that I'm competitive... but I did try and count and use a calculator.... @RefillandG
SECURITY ADVISORY “NginxDay”: NGINX LDAP Reference Implementation Zero Day Vulnerability We have detailed the zero-day and relevant mitigation here: appcheck-ng.com/zero-day-vulne… #SecurityAdvisory #ZeroDay #NqinxDay
The best shot/chaser of all time
If you've ever wondered how you are supposed to react when you find out someone you know is trans and has transitioned, remember that Star Trek taught us exactly how.
Which one of you smartarses did this? 😂
