🥳#OST2_5th_Anniversary🎉 OST2 is made possible by instructors who want to help other security engineers learn skills faster. So what we'd really like to see for this coming year are more instructors teaching more diverse topic areas. If you 🫵 have an idea for a class, reach out at teach at ost2.fyi!

🥳#OST2_5th_Anniversary🎉 So what can we look forward to this coming 6th year of #OST2's existence? We never want to count our chickens before they hatch, but we have instructors who've already recorded videos on classes such as Intel x86 virtualization, Bluetooth Low Energy, Industrial Control Systems, and Cloud-Native App Vulnerabilities!

🥳#OST2_5th_Anniversary🎉 OST2 needs more sponsors to keep growing! https://ost2.fyi/Sponsorship.html If you want your company to sponsor #OST2, reach out via email at "sponsor at ost2.fyi". It's much more cost effective than sponsoring conferences, and reaches far more people!

🥳#OST2_5th_Anniversary🎉 Partners and Sponsors provide us with funds to help with overhead costs such as running the site, paying video editors, etc, so that individual donations always go directly to instructors to show them your support.

Your CPU speaks assembly. Shouldn't you? Master x86-64 with the most common instructions and unlock reverse engineering, exploit dev & OS internals. But this is no skim class; it takes ~28h on average (not counting the final lab). Get started on Architecture 1001: x86-64 Assembly https://ost2.fyi/Arch1001 by @xenokovah@infosec.exchange today for mad skillz tomorrow!
