This assignment involves generating a total of five attacks on two programs having different security vulnerabilities. Outcomes you will gain from this lab include: You will learn different ways that attackers can exploit security vulnerabilities when programs do not safeguard themselves well enough against buffer overflows.For Phase 4, you will repeat the attack of Phase 2, but do so on program RTARGET using gadgets from your gadget farm.

Students will gain first hand experience how a Message Authentication Code (MAC) is calculated using one-way hash using a key and message. The lab explores how an attacker can intercept a client request, expand the message and calculate a correct MAC without knowing the key.Implementing buffer overflow and return-oriented programming attacks using exploit strings. - Attack-Lab-1/Attack Lab Phase 2 at master · jinkwon711/Attack-Lab-1Phase 1.md.

Any heart attack, including an NSTEMI, is a life-threatening medical emergency and needs care immediately. If you or someone you're with appears to be having a heart attack, call 911 (or the local emergency services number for your area) right away. Delaying medical care can be extremely dangerous and can lead to permanent heart damage or death.
