Grundlagen der Cybersicherheit 1 Michael Backes, Ben Stock

The results of the endterm exam are now visible in the CMS. Also, all exercises should be graded now (with less verbose feedback than usual). If you are missing the results for an exercise sheet, please let us know.

We have not set a date for the exam inspection, but it will likely happen in the week of February, 19th.

The tutors have graded the exercise for those students that were close to 50% on the practical sheets. All students that cannot participate in the exam have been notified.

Please find the seating plan here: https://cms.cispa.saarland/cysec1_17/dl/50/Seating_Plan.pdf

As a gentle reminder: please show up for the exam at least 10 minutes before its start (start of the exam is Tuesday, at 1pm in GHH) to allow for proper seating for all students.

The results for the evaluation are now available for download in the "Materials" section. We'll discuss some of the feedback also in the lecture (likely next week).

Also, the event which was planned for the 26th in GHH was canceled. Hence, we'll have the lecture as usual in GHH.

Since there was bit of confusion and some errors, let me give you a hint for the exercise: The shellcode which we provided contains several pushes. That means that if you add a NOP sled (not necessary in this case due to the exact address being known) *before* the shellcode, the pushes in the shellcode may overwrite some of the instructions of the shellcode itself.

Hence, either add padding *after* the shellcode and before the return address or place the whole shellcode *after* the return address (accounting for the change in address to jump to).

The deadline for the submission of the 9th exercise sheet is set for Sunday, January 7th. This is to allow everyone to attend a tutorial this week such that you can get better acquainted with gdb. If your tutorial was scheduled for Monday, please attend any other tutorial this week.
