Attack lab phase 4
Phase 2 Phase 2 involves injecting a small amount of code as part of your exploit string. Cluster 5 corresponds to the DDoS attack phase which continues 5 s A University of Alberta virology lab has uncovered how an oral antiviral drug works to attack the SARS-CoV-2 virus, in findings published May 10 in .PHASE 2. Phase 2 involves injecting a small code and calling function touch2 while making it look like you passed the cookie as an argument to touch2. If you look inside the rtarget_dump.s fil and search for touch2, it looks something like this: If you read the instruction pdf, it says, "Recall that the first argument to a function is passed in ...For this phase, we will be using the program rtarget instead of ctarget \n. This phase is the same as phase 2 except you are using different exploit method to call touch2 and pass your cookie. \n.

This phase is the same as phase 2 except you are using different exploit method to call touch2 and pass your cookie. \n. In the pdf it tells you to find the instructions from the table and one of the instructions you will use involve popping rdi register off the stack, \nPhase 1. This phase is so easy and it just helps you to get familiar with this lab. You can choose to use the command objdump or just use gdb to solve this lab. One way is to use the command objdump and then you get the corresponding source code of getbuf () and touch1 () function: 4017a8:48 83 ec 28 sub $0x28,%rsp.
This is incorrect. The output of func4 is compared with [rsp + 8], in which the first number was stored. If we write the desired input as (a, b), then we have a = func4 (7, b) and 2 <= b <= 4. To understand what func4 (x, y) does I recommend that you convert it to C. See my answer to this question for an illustration.For this phase, we will be using the program rtarget instead of ctarget \n.

Third guess is thus (8 + 10) / 2 = 9 which brings the sum to 27 with 10 more to go and just a single guess, so that means the number is 10. TL;DR: the correct input should be 10 and 37.
