OST2 is putting out a request for proposals for an opportunity to be funded to create classes on UEFI and/or ACPI. If you are interested, please reach out to teach🌀ost2.fyi with a proposed class syllabus. ost2.fyi/Training-RFPs.…

Move from basic fuzzing to a high-performance workflow. Fuzzing 1001 ost2.fyi/Fuzz1001 bridges the gap between theory and practical research. Master AFL++, PCGUARD, LTO, and ASAN using real CVEs from Xpdf and tcpdump.

Tired of guessing inputs? Let the computer do the work! Learn about symbolic execution from @barbieauglend in "Reverse Engineering 3201" ost2.fyi/RE3201 and use SMT solvers to find the exact inputs to reach vulnerable code. Stop guessing, start solving!

We're in discussion to form a partnership with the UEFI Forum. But as part of that we need to propose classes that can be taught on the topics they're involved with. Things like UEFI Measured Boot in particular would make a lot of sense now that we have robust TPM classes at OST2

Like TC1101 & TC1102, TC1103 has the goal of helping developers get bootstrapped on using TPMs more quickly than if they were to just rely on reading the spec or API documents alone. The topics for TC1103 are: - Introduction to the Feature API (FAPI) - Creating keys using FAPI - Policy using FAPI - Full-disk encryption primitive (FDE) using a TPM - TPM operations for FDE - Advanced TPM Policy usage using tpm2-tools and tpm2-tss - Policy using locality - Policy using the TPM clock and reset - Policy using the TPM's internal NVRAM - Handling external keys using a TPM

We've got a decent number of instructors in the queue to create new classes in 2026 too, but we can always use more! Classes are a significant investment of time, but they also pay off in a significant way for the number of people you will help over many years!
OpenSecurityTraining2@OpenSecTraining

A special thanks to the instructors who stepped up in 2025 to release new classes: * Francesco Pollicino - Fuzzing 1001: Introductory white-box fuzzing with AFL++ - ost2.fyi/Fuzz1001 * Xusheng Li - Debuggers 1103: Introductory Binary Ninja - ost2.fyi/Dbg1103 * Bill Roberts - Trusted Computing 2202: TPM 2.0 Programming using Python and the tpm2-pytss libraries - ost2.fyi/TC2202 * Xeno Kovah - Bluetooth 2222: Bluetooth reconnaissance with Blue2thprinting - ost2.fyi/BT2222 If you've got an idea for a class that you want to share with 33k friends, reach out at teach 🌀 ost2.fyi!

In 2026 we will be fundraising to add a gamification plugin to our Open edX servers. This will add a leaderboard for learners, and provide a new way to track your sub-class-granularity skills that you're picking up on the site. To help early, donate here: every.org/ost2/f/lets-ga…
OpenSecurityTraining2@OpenSecTraining

A sincere thank you to everyone who donated to #OST2 as an individual in 2025 (and especially those who took advantage of corporate non-profit donation matching)! Your donations always go directly to instructors as an honorarium, and show them that you value what they do for OST2 and you want them to keep helping the world!

We also want to thank everyone who volunteered for #OST2! From completing classes as a beta student, to submitting subtitle fixes, to running our Discord, helping with the next version of the website, contributing graphics, etc, OST2 wouldn't be successful without our volunteers!

#OST2 has a ton of material relevant to RE. And our ost2.fyi/Dbg1101 introduction to IDA as a debugger class instructor, Christina Johns @bitmaize, is working on "RE2001: Introductory Static Analysis of C-based programs", which will unlock many new classes!
OpenSecurityTraining2@OpenSecTraining

We are happy to announce that Hex-Rays @HexRaysSA, makers of IDA, have become a 🥇Gold-level sponsor of #OST2! Learn all the latest about their software reverse engineering tools here: ost2.fyi/Sponsor_HexRay…
