A quick follow up from one of my earlier post regarding a compiled list of sample PCAP files, here are more files for your practices on Wireshark features and techniques, of which some of them even have blog posts on the decrypting of the files. I hope they are helpful to you too.

Hacksplaining: Learn to Hack

Hacksplaining is one of the best website that I have seen so far in terms of the way it teaches people about web vulnerabilities. It uses a very simple and fun way of teaching people about the concepts and theory of web vulnerabilities. To make the deal even better, it is free. I don’t know who are the folks behind this website, but I really like how they make education seems so fun. Kudos to them for the amount of time they have invested in coming out with all those examples and exercises, and etc.

Also, I really like their tagline,

“learn to hack, learn to protect yourself”

I fully agree with it, just like when you play sports, you need to know the rules and the various techniques and tactics that can be deployed during an attack, before you are able to effectively defend against them. Same concept applies here, if you don’t understand cross site scripting or SQL injection, how are you supposed to ensure that your web application is protected against them?

The following are the list of techniques that you can learn through Hacksplaining‘s interactive way of teaching you web vulnerabilities,

SQL Injection
Clickjacking
Session Fixation
Cross-Site Scripting
Weak Session IDs
Reflected XSS
Dom-Based XSS
Cross-Site Request Forgery
File Upload Vulnerability
XML Bombs
Open Directs
User Enumeration
Broken Access Control
Unencrypted Communication
XML External Entities
Information Leakage
Password Mismanagement
Privilege Escalation
Command Execution
Directory Traversal

Compiled List of Sample PCAP Files for Practice

I was once tasked to perform some investigation on a packet capture (pcap) file to retrieve some information. Before I was given the task, I don’t even know anything about pcap file. Some simple research will tell you that it is a file that captures network traffic.

Interesting uh?

One of the best tool used in the industry for performing packet capturing would be no doubt, Wireshark. The tool itself has many features, which I am not going to do a step-by-step guide today. What I am going to share is actually a compiled list of sample pcap files.

You are right, a compiled list of sample pcap files consolidated by people in the community and listed together in the Wireshark Wiki. It is very useful to people learning Wireshark and want to perform some analysis or test out some features on good pcap files which has more variants of realistic network traffic, furthermore, the choices are vast and interesting (since you did not create it yourself, there are some element of surprise).
