Friday's Exam Prep Office Hour

Hey everyone!

Since we want to give you one last in-person opportunity to ask questions about the whole content of this lecture (and because we expect that you are already busy with other exams as well), we decided to skip the last tutorials and instead offer you a grand office hour this Friday, 4 PM, right before the lecture event. There you can ask us any questions about any topic of this lecture.

If you want to participate in-person, you may attend this office hour from 4 PM on (until there are no more questions left and we go to the Ratskeller) in the CISPA lecture hall. Of course, you can also participate in the office hour via Zoom (use Luis' tutorial Zoom link for this).

Note: In case you want to attend on site, please bring a mask as we do not know how many people will come and at CISPA there's still a mandatory rule to wear a mask, if more than 15 people are in the lecture hall at the same time.

Cheers,

Luis.

Sheet 8 - Angr Exercise

Written on 23.06.22 by Daniel Weber

Hi all,

 

we observed that some angr versions can not solve exercise 2. More precisely, the sample solution does not work with angr in the pip version 9.1.11611.

Hence, we recommend that you update your angr installations [1] to at least 9.2.6 [2] in case your solution does not work. If you… Read more

[1]: If you haven't had angr installed in the first place, you should be fine.

Broken PDF Contents

Hi all,

Hi all,

We observed that some of your solutions contain missing or wrong content in the PDF forms. This can easily happen depending on your PDF viewer.

To double-check you could, e.g., download your submission from the CMS again and check whether the file still contains your answers. It is also often helpful to use the Print-As-File function of your PDF viewer and print the submission again as a PDF.

Cheers,

Daniel

PS: This does not mean that all your submissions must use the PDF forms. Feel free to submit other styles of solutions as long as they are readable.

Hello there,

we, the Capture-the-Flag Team saarsec, consisting of students and lecturers from Saarland University, are giving a workshop to familiarize students with Capture-the-Flag competitions as well as attacking and defending against security vulnerabilities. CTFs are a great way to actually fiddle around with the practical details of mounting attacks and defenses that were theoretically discussed during your studies. This practical experience can not only be beneficial for your studies but also come in handy during later stages of your career. The workshop starts with a short introduction to Linux, followed by different topics such as File Inclusions, SQL Injections, and Command Injections. For each topic, we will discuss how we can find these vulnerabilities, exploit them on a large scale, and how we can fix them. Then, for each each topic, you'll spend more than 50% of the time in each slot on actual challenges. At the end, we will host a CTF for all workshop participants where they can use their newly acquired skills against each other.

FAQ:

Q: When and where?

A: April 10th and 11th, the format (virtual, onsite, or hybrid) will be announced later

Q: Requirements?

A: We do not require any certain skills as we will start with the basics. However, the knowledge from Cysec1 or Security is definitely an advantage.

Q: Sounds awesome! Where can I register or get more information?

A: https://workshop.saarsec.rocks

 

See you there,

saarsec
