I just finished the "Masterclass: Hacking open source fuzzers for smarter bughunting" from @zerodaytraining @alisaesage As a Hacker and Vuln Re, I've been craving for practical insights in fuzzing, Alisa delivers just that. Her master hands-on approach coupled with a focus on real-world fuzzing techniques, sets this course apart. + What I loved: No Fluff. Alisa dives straight into the training material. No time wasted on just theory. Def not for beginner's 2. Fuzzer afl, WinAFL, libfuzzer you name it, she covers it. 3. Code Coverage. Alisa demystifies code coverage and shows how to wield it effectively. + In summary, Alisa's masterclass is like a turbo boost for the bug-hunting journey. Highly recommend training. Alisa's work can be explored further on https://t.co/PvYsa9ZyGP My fav part that I wish I could take at some point : https://t.co/oxKQbp52iV +

I had the chance to attend the "Masterclass: Hacking open source fuzzers for smarter bughunting" by @alisaesage An amazing class, giving different perspective and insights on fuzzing! As I have attended other fuzzing classes, getting a perspective from each person is for me the most valuable piece. Not only knowing how to use a tool, but also why, when and understanding the thought process @zerodaytraining is on its own an amazing resource as well, covering other aspects of binary analysis. The "0-day insights" are pure gold, research at the highest level. *** What a great way to start the year 🎉 Thrilled with almost completing the Hypervisor Vulnerability Research course by @zerodaytraining! Comprehensive content, engaging exercises, and expert insights by @alisaesage 💯 recommended!

Had the pleasure of limited access to a course on Hacking open source fuzzers for smarter bug hunting by @alisaesage over the weekend, which is available for purchase on the @zerodaytraining website. 1/2 I would highly recommend looking around the available courses and bug write-ups on the @zerodaytraining website, it’s a goldmine of information. A personal favourite page is https://t.co/MvKkhdAipV which covers exploitation of simple bugs in Parallels 2/2

Had the opportunity to learn from @alisaesage on “Hacking Open Source Fuzzers”. Since I’m a beginner to fuzzing, this course was really helpful to deep dive in modern fuzzing techniques. The course starts by give an intro to fuzzer components and then ramps up by looking under the hood of most commonly used fuzzer. I’d surely would like to revisit this course over time since it’s packed with information. In the future, I’d love to try https://t.co/wiq2B3D1HU @zerodaytraining

(1/3) The last few months I have been enjoying and learning about vulnerability research from one of the best trainings available today. The 4-day Zero Day Vulnerability Research course from @zerodaytraining by @alisaesage is not only exceptional on a technical level, (2/3) but it also teaches you a methodology to follow, and personally, what for me is most valuable and concentrates Alisa's years of experience and knowledge: it introduces you to the mindset necessary for your vulnerability research to be successful. (3/3) I am already applying the knowledge I have acquired and I am eager to continue learning from her. I'm sure I'll be taking some more of her courses. For now, I will enjoy the course for the second time. Don't miss the opportunity to do it: https://t.co/MrzAWf4z6x

Finally managed to find some time to commit to the Zero Day Vulnerability Research course! Loving the organized and systematic approach. Kudos to the impressive research and theoretical insights from @zerodaytraining .

I just finished the "Masterclass: Hacking open source fuzzers for smarter bughunting" from @zerodaytraining by @alisaesage. I took around 4 hours to complete this course, unlike other courses which focus on basic fuzzing, this course is really comprehensive. It is not for beginners levels, it is for intermediate. The masterclass are focus on AFL and WinAFL since it is a gold standard for industry. Alisa explains about Old Fuzzing and New Schools Fuzzing (Coverage Guide Fuzzing) and Anatomy of Fuzzer. She summarizes a lot of things in this Masterclass. The most part of the video which I love is going through code reviews of each function in Fuzzer. I would like to recommend this course to anyone who is interested in fuzzing, especially who want to modify Open Source Fuzzer to work with their target software. She is a great talent hacker, who likes to break things and share knowledge with the community.

@alisaesage 1) Although the hypervisor miniclass ended abruptly, I'd like to say thanks for the good basic overview and introduction into the hypervisor landscape. Some questions given were irritating/personal and not topic related, but Alisa handled them all professional. 2) I can highly recommend her training for starters into hypervisor vuln research. Thanks for the invitation, Alisa ;) Looking forward to more pwning from your side. If you have a chance, take her classes.

I just finished my first round of Zero Day Vulnerability Research training https://t.co/B2nAFXysp3 from @zerodaytraining. It is exceptional for its beginner-friendly approach, comprehensive and easy-to-digest structure, and practical application of concepts. It provides valuable insights into vulnerability research, foundational theory, and skills necessary for further specialization. From day one, the training sets a solid foundation by introducing abstract models, essential theories, and the mindset required to become an effective zero-day engineer. One of the key strengths of this course is its structure, which seamlessly integrates theoretical lessons with practical exercises. The inclusion of real-life case studies and security vulnerabilities discovered by the author adds immense value, making the learning experience engaging and informative. I plan on revisiting the training to absorb its comprehensive content more thoroughly.

@mhz_cyber

I just finished the "Masterclass: Hacking open source fuzzers for smarter bughunting" from @zerodaytraining by @alisaesage. The 4-hour training is an eye-opening to more advanced fuzzing and it's more oriented to learn how to customize the fuzzer for your own purpose ...🧵 and not to learn how to fuzz. The masterclass focuses on AFL and WinAFL since those are the most powerful frameworks for fuzzing and explains the anatomy of fuzzing and the differences between the old generation fuzzers methodology and the new ones. I don't think the masterclass is for beginners as much as for intermediate people or those with fuzzing experience. There are some interesting exercises to solve in the training and some nice dive in the source code of the fuzzers to understand its internals.

The Vulnerability Research training from @zerodaytraining led by the incredibly insightful Alisa Esage was a game-changer for me. This four-day comprehensive education proved to be an incredible experience, combining more than a decade of research insights into vulnerability with hands-on practical applications of real-world case studies. Alisa's approach to teaching, emphasizing on the development of the right mindset and cognitive skills necessary for vulnerability research, truly sets this course apart. It’s not just about understanding a specific attack; it’s a deep dive into the essentials of vulnerability research, from memory corruption and logic bugs to navigating complex codebases and the nuances of modern software. What stood out to me was the practical tips from Alisa's own Pwn2Own experiences. The course doesn't just feed you the information; it challenges you to engage actively with the content, encouraging a researcher's mindset that's crucial for anyone serious about delving into VR. Whether you're coming from a software development background or other security related field, this course is invaluable. It not only provides a well-structured self-learning approach but also encourages for continuous improvement of key concepts in vulnerability research. Highly recommended for those interested in vulnerability research.

Last night around 1 AM I finally finished "https://t.co/LcxeMtR1Nw" by @alisaesage of @zerodaytraining . Here's my review 1/4 1st, WOW! it's 4 hours of pure gold. Initially, she goes through the important core theories of fuzzing, and then she connects the dots by walking you through AFL's source code, which helps you deepen your understanding of how things work under the hood. 2/ The guided labs where you are given a quick task, and then shown the solution are awesome. Not only does it strengthen your understanding of the material, it also builds your confidence! 3/ The final part "Common Problems & Tips" will save you hours if not days of headaches with tips that can only come from extensive hands-on experience. I had two aha moments during that part. 4/ Overall, this is an easy 5-star. It's a great mini-class for both beginners and professionals. Thanks @alisaesage for generously offering this for free and giving back to the community! (also thanks for accommodating me)

@alisaesage Hey Alisa. Long time exploit dev here. Really want to purchase some of your other courses and I figured this masterclass would be a good way to test my knowledge and see the way you teach. I’m always looking to learn more. Thanks.
