SCADA, A PLC’s Story
Previous month I've been a speaker at the M0leCon Conference (Turin, Italy, 30 November) with a talk named: SCADA, A PLC's Story During the last few years, SCADA quickly gained the major news headlights with different frightening articles: from STUXNET to breaches like the electrical power supply grid in Ukraine (December 2015). Since SCADA systems are actively used across various industries (oil & gas, pharma, power plants, critical infrastructures) to perform critical operations on daily basis, SCADA security has also become...
SolarPuttyDecrypt
During a recent Red Team engagement, I was able to become domain admin on the client’s network; I decided to investigate further into the “sys admin” workstations and management network in order to recover more information about the network topology and assets, dumping more password and gaining access to firewalls/switches and servers’ VLANs.Enumerating the sysadmin’s workstations, I discovered a windows tool used to connect via SSH. TL;DR SolarPuttyDecrypt is a post-exploitation/forensics tool to decrypt SolarPuTTY's sessions files and retrieve plain-text credentials....
Windows Kernel Debugging & Exploitation Part1 – Setting up the lab
Recently I was thrilled with the opportunity to build a PoC for ms-14-066 vulnerability aka “winshock” (CVE-2014-6321). While that will be material for another blog post, in order to debug the vulnerability, I had to set up a lab with windows kernel mode debugging enabled. So, without any further ado, here my setup and the steps used in order to enable Windows Kernel Debug. Setup Host system: Windows 10 with VMware Workstation 15.1.0 (build-13591040)Guest systems:Windows 7 x86 ultimate sp1 (debugger) ...

Rubyzip insecure ZIP handling & Metasploit RCE (CVE-2019-5624)
This is a re-posting of the original article "On insecure zip handling, Rubyzip and Metasploit RCE (CVE-2019-5624)" that I have wrote on DoyensecDuring one of our projects we had the opportunity to audit a Ruby-on-Rails (RoR) web application handling zip files using the Rubyzip gem. Zip files have always been an interesting entrypoint to triggering multiple vulnerability types, including path traversals and symlink file overwrite attacks. As the library under testing had symlink processing disabled, we focused on path...
A Drone Tale
During the previous months I've been a speaker for various international conferences: Hackinbo (Italy, 26-27 May), Sec-T (Stockholm, 13-14 September) and Hacktivity (Budapest, 12-13 October) with a talk named: "A Drone Tale: All Your Drones Belongs To Us". A talk where I detailed analysed the DJI Phantom 3 model’s architecture , its attack vectors, reverse-engineered the SDK and the network protocol. I also had a specific focus section on Drones Forensics Artefacts Analysis and Methodology. Here you can find and download...
