Introduction Today I’d like to share a quick analysis initiated during a threat hunting process. The first observable was found during hunting process over OSINT sources, the entire infrastructure was still up and running during the analyses as well as malicious payload were downloadable. Analysis My first observable was a zipped text file compressing a […]Read more "Is Hagga Threat Actor (ab)using FSociety framework ?"
Introduction Phishing kits are tools that dark side experts provide to the community of criminal phishers to facilitate the construction of malicious Web sites. As these kitsevolve in sophistication, providers of Web-based services need to keep pace withcontinuous complexity. Today I am proud to introduce a long time research that Andrea Venturi, Michele Colajanni, Giorgio […]Read more "Phishing Kits: Threat Actors Analysis Research"
Introduction System calls are the ultimate high-level atomic actions that Malware writers might control. System calls sequences are the defacto ultimate way to divide behaviors between good and bad. For example the system call “encrypt” could be used by a privacy oriented software to encrypt content before shipping-it to a cloud storage or it could […]Read more "Windows System Calls For Hunters"
Today a simple update from my Cyber Threats Observatory (available HERE). Six months of this crazy year are over and it’s time to check some cyber threats trends. Once upon a time there was Emotet. It was on the TOP 5 on every ranking list, it reached the 5th epoch and it was able to […]Read more "Cyber Threats Tracker: Status Update"
Introduction When I’ve firstly seen the technique behind the Shellcode execution through Microsoft Windows Callbacks, I thought it was pure magic. But then, digging a little bit on it, I figured out that it was just brilliant ! Nowadays this technique is quite used in underground communities to inject shellcode into running processes so I […]Read more "Running Shellcode Through Windows Callbacks"
Introduction We are living difficult times. From pandemic to Russia-Ukraine war. I was tempt to let a white post for remembering such a devastating times in my personal web corner, but I came out with the idea to remember these times by analyzing an involved sample in current cyber-conflicts. I start looking for Malware and […]Read more "A Malware Analysis in RU-AU conflict"
Disclaimer This blog post, as all the blog posts in my web-corner, want to share cybersecurity related researches and personal experiences in order to improve threats analysis, risks and cybersecurity awareness.

Kubernets and server-less applications would be the biggest next things to protect. So it would be a great idea to start to get practice on such environment, especially if you had no previous opportunities. Here my post on how to build your first kubernets cluster based on Raspberry Pi4 ! Raspberry is a cheap and […]Read more "Building your Kubernets Cluster For Cybersecurity Prototyping"
