January was an interesting moth for CTI practitioners! I took some time and collected the major articles and presentations that I read and watched during January 2019.
I hope you enjoy it. Continue reading “Threat Intel Reads – January 2019”

My Top 20 CTI/DFIR Talks for 2018
Another year has passed and lots of good CTI/DFIR stuff have been presented! I took some time to watch again some of my favourite talks within 2018 and list my favourite 20 ones. The list provided below has a CTI focus, however some of the most representative talks related to blue team/red team as well as ICS have been selected. I hope you enjoy it!

CrowdStrike’s 2018 Mid-Year Review
During the past week CrowdStrike published its 2018 Mid-Year Review call “Observation from the front lines of threat hunting“. This report provides insights, trends and details on today’s most sophisticated cyber attacks observed by CrowdStrike Falcon OverWatch team.
Some interesting points of the report include:
Anti-Virus Log Analysis Cheat Sheet (v1.5)
Florian Roth published the new version of Anti-Virus Log Analysis Cheat Sheet (version 1.5). I highly recommend to implement monitoring of the events included in this cheat sheet. To my mind, this is the easiest and quickest win and AV logs are one of the first things I hunt whenever I go to a new environment.
The new version has information on :

There is still life for Offensive PowerShell
It is a fact that security controls and detection capabilities against Powershell attacks have been improved during the last years. However, are Powershell attacks still evolving?
Recently, we have read quite a few articles regarding Offensive Powershell:

WMI Persistence Goes Mainstream
This blog post from CrowdStrike provides some good information related to the persistence mechanisms used by WannaMine cryptomining worm. According to the post, WannaMine employs “living off the land” techniques such as Windows Management Instrumentation (WMI) permanent event subscriptions as a persistence mechanism. It is really interesting that crypto mining malware adapt so quickly their TTPs and use techniques that are mostly used by APT groups.
Post Exploitation 101
I read the following tweet by Florian Roth a couple of days ago:
People frequently ask me about process hollowing/doppelgänging, spectre/meltdown, skeleton keys & attack vectors involving liquid nitrogen.
Recently I replied:
Would you notice someone running “whoami” on one of your servers? https://t.co/Y4e8YaFdtt— Florian Roth (@cyb3rops) January 27, 2018
I could not agree more with the reply from Florian. See below a list of resources that help tuning detection mechanisms for post exploitation activities.
- Windows enumeration commands
- Windows post exploitation resources
- Living off the land
- Windows commands abused by the attackers
- Post Exploitation using WMIC
- Post Exploitation in Windows using dir Command
- Post Exploitation on Windows PC
- Linux post exploitation
- Patterns of behaviour
Enjoy and happy hunting ;)
My favorite DFIR presentations for 2016
2016 was a year full of interesting presentations and conferences! I took a moment to think about the presentations that helped me better understand the threat landscape, introduced me to new tools and processes, provided inspiration for my team and help me with my daily operations.
The selection of the presentations below is subjective but indicative of the trends regarding the DFIR community during 2016. Moreover, the below sequence is completely random.
I would appreciate any feedback and I would be more than happy to be sent your ones! Enjoy!
Threat Intel Annual Reads 2016
Some of you may or may not know my weekly newsletter called “Threat Intel Weekend Reads” that started being published in December 2014. What I tried to do today was to go back to all the newsletter editions of 2016 and select my favorite headline articles. During the upcoming days I will try to deep dive once again and provide more insights on DFIR, Threat Intel and Threat Hunting! Any feedback would be more than welcome! Enjoy!
