Line +32 checks that sscanf read exactly 1 number, otherwise the bomb will explode. Line +59 is checking the return value of func4 against 610, so you need to figure out what number to feed func4 such that it will give 610 back.The five solutions for target n are avalable to you in the targets/target directory, in the following files: Phase 1: ctarget.l1, Phase 2: ctarget.l2, Phase 3: ctarget.l3, Phase 4: rtarget.l2, Phase 5: rtarget.l3, where “l” stands for level. 4.

The Cyber Kill Chain is a framework for understanding cyber attacks, analyzing intrusions, and planning cyber defenses. It is used throughout the industry by cyber security professionals in security operations, incident response, and cyber threat intelligence to investigate and report how a cyber attack happened.Figure 1 summarizes the four phases of the lab. As can be seen, the first three involve code-injection (CI) attacks on CTARGET, while the last involves a return-oriented-programming (ROP) attack on RTARGET. There is also an extra credit phase that involves a more complex ROP attack on RTARGET. 4 Part I: Code Injection AttacksFor this phase, we will be using the program rtarget instead of ctarget \n.
