Our latest guide explains everything you need to know about encryption, and why it’s something you should implement straight away. https://lnkd.in/gxbY5kBG

But, how fast is your symmetric key encryption method? I did some tests here: https://lnkd.in/eXMuxvSy

Learn how to decrypt SMBv2 traffic using two methods: one by extracting a password from a hash and another by using an NT hash found in a dump file. With all the necessary information, generate a session key (SK), incorporate the session ID, and decrypt the traffic.

This might be the most important video you watch all year. As you know, DNS is the root zone of all security issues. Anything else is just a delegate of that. Jokes aside, this is actually a great presentation. I always want to read deep documentation, but tend to fall asleep and this references a lot of the official RFCs. Learned some new stuff watching this, such as why there are always underscores on txt and spf records https://lnkd.in/ga45DWQC

Based on the image below, in that there is a pair of keys, what type of encryption is this? A = Symmetric Encryption B = Asymmetric Encryption C = Hashing Encryption D = None of the above E = Not sure / Something else

What is encryption and why do you need it? 66 seconds.

Quick Insight on Encryption Protocols

Today I learned how to decrypt SMB2 traffic by create session key and import it then I also learned that decrypt Kerberos blobs using keytab file can decrypt SMB2 traffic as well!

Crowdstrike just released a Root Cause Analysis of their outage. Part of the blame is placed on a change they made to detect novel inter-process communication attacks. Speaking of inter-process communication...Laurie made a in-depth video on the fundamentals of IPC, with a focus on the Android Binder. It's a great way to get a better picture of how complex modern IPC systems can be. #IPC #OS
