About this course
Return-oriented programming sounds mysterious until you build one yourself on a program made for learning. In this course you compile a small, deliberately vulnerable binary and discover why a buffer overflow alone cannot call a function that needs an argument. You meet the x86-64 calling convention, learn how a chain of tiny instruction sequences ending in ret can steer the processor, and locate a usable gadget with standard disassembly tools. You then lay out a working chain in Python and watch it succeed. The later lessons explain the defenses that shaped all of this: non-executable memory, address randomization and position-independent code, plus the idea behind a ret2libc shell. Knowing how these attacks work is what lets you argue for memory-safe code and modern mitigations. All practice stays on a binary you own.

Questions about this course
Is this a subscription?
No. You pay $9.99 once for this course. There is no subscription and nothing renews automatically. Prices are in US dollars; taxes may be added where required.
What exactly do I get?
All lessons and labs of this course, the final exam and the certificate, including later updates to the course, for as long as Tutorvo offers it. Access is personal and tied to your account.
Can I get a refund?
Yes. If you are not satisfied, email hello@tutorvo.com within 14 days of buying and we refund the course in full via Stripe. The guarantee does not apply once a certificate for the course has been issued to you, or where there are signs of abuse.
When can I start?
Right after payment. Access starts immediately at your request; for consumers in the EU/EEA the statutory right of withdrawal therefore ends once access has begun, while our 14-day money-back guarantee applies regardless.
Do I need Excel or other software?
No. The labs run in a spreadsheet inside your browser on a laptop, tablet or phone. Function names and syntax follow Excel.
Is the certificate an official qualification?
No. It confirms that you completed all lessons of the course and passed its final exam. It is not an official, state-recognised or professional qualification. The name is taken from your profile when the certificate is issued.
