🐲 Ghidra Tips 🐲- Malware Encryption and Hashing functions often produce byte sequences that are great for #Yara rules.
Using #Ghidra and a Text Editor - You can quickly develop Yara rules to detect common malware families.

Hashing and encryption functions make good targets for #detection as they are reasonably unique to each malware family and often contain lengthy and specific byte sequences due to the mathematical operations involved.
These characteristics make for good Yara rules 😁

[3/20] The biggest challenge is locating the functions responsible for hashing and encryption. I'll leave that for another thread, but for now...
You can typically recognize hashing/encryption through the use of bitwise operators inside a loop. (xor ^ and shift >> etc).
You can typically recognize hashing/encryption through the use of bitwise operators inside a loop. (xor ^ and shift >> etc).
If you utilise API hashing in your #malware or offensive security tooling. Try rotating your API hashes. This can have a significant impact on #detection rates and improve your chances of remaining undetected by AV/EDR. See below for an example with a Bind Shell vs #Virustotal.
Since API hashing can be confusing, most attackers won't rotate their hashes with each iteration of malware. Those same hashes can be a reliable detection mechanism if you can recognize them in code.
Luckily finding these hashes isn't too difficult, just look for random hex values prior to a "call rbp".
If you're unsure whether the value is an API hash, just google it and see if you get any hits. Most of the time, identification can be a simple google search away.

The first Network Security session at #PESW (organized by @FIT_CTU) has been started by @vaclavbartos1, the chair who introduces our speaker Lukáš Hejcman @FIT_VUT & @CESNET_cz. You may still visit us in Horoměřice at pesw.fit.cvut.cz/2022 until Saturday!
Matej Hulák (@FIT_CTU & @CESNET_cz) is the second speaker. We move from Packet Capture by Lukáš H. to Traffic classification topic by Matej.
3rd speaker of "Session 3 - Traffic Capture and Detection" - Richard Plný presents #CryptoMining #detection in #network #traffic. Using #IPFIX and "weak classifiers".
Are you using any of the Microsoft Security products and/or #Sentinel? Then this thread is for you! The best resources for #KQL Advanced Hunting Queries or Analytics rules in my opinion.

Wait... "the peak is over" doesn´t mean "it´s back to normal"!
Confinement will only fall on December 15,
if there´s less than 5.000 new cases a day.
(today it´s ~9.000).
France is disappointed.🙁
Although they certainly can make it happen.

So, I was trying to summarize my thoughts on why THREAT #DETECTION is hard (1/m)
Naturally, first a quip on "well, the attackers don't want to be detected" came to my mind ... (2/m)
Well, except for ransomware after they are ready ... (3/m)
As #COVID19 cases are found to spread, #Melbourne (city of ~5 million) tries to contain them by going into #Lockdown.
(The interview features the idea of a dedicated #Quarantine building - that would actually help, I guess)...

"People acting as if the pandemic was over was 'not the answer, it is part of the problem' ".
"The virus had leaked from postcodes already under the stay-at-home orders to other parts of #Melbourne."
(and beyond, it is feared).

Due to #Melbourne's outbreak, neighbouring South Australia is about to completely close it's borders to #Victoria.
