Work Experience
Software Developer
ReaQta
- Re-engineered and consolidated a tool for dynamic malware analysis and integrated it with the company's software suite (Python 3).
- Developed a tool to automate testing of offensive techniques selected from the MITRE ATT&CK framework categorization by tactic and technique (Python and PowerShell). The tool's main purpose was to measure ReaQta EDR software detection capabilities.
- Integrated a tool for automatic creation of a realistic, multi-host, virtual laboratory, including Active Directory domain-joined Windows and Linux machines.
- Emulated a real, advanced persistent threat (APT) in preparation for MITRE evaluations. This activity included thorough research on FIN7/Carbanak threat actor offensive capabilities and automatic testing of the collected offensive techniques.
- Developed the company's Linux endpoint monitoring agent.
Software Developer
Sistemi & Automazione
- Conducted research on an ontology matching problem and the existing state of the art on how to approach and solve the problem efficiently.
- Devised a tool for automatic data type detection using machine learning. The tool receives data in tabular form and tries to guess each column data type, providing hints on type matching to the user.
- Conducted a penetration test on the company's internal network and exposed web applications.
Software Developer
National Research Council of Italy
- Developed software for distributed cracking of various cryptographic protocols (OpenGPG, OpenPGP, BitLocker, and AES Crypt).
- Designed and integrated a multi-component software solution for distributed shape optimization in the aeronautical field, using C++ and Qt framework.
- Coded a tool for optimal path computation and visualization using GPUs (C++ and CUDA).
- Designed and implemented multi-component software for dynamic malware analysis based on virtualization and introspection, using Python and C language.
Experience
RBF4AERO
https://www.youtube.com/watch?v=eThibFzEPNIMy role in this project was to devise and implement a multi-component platform that integrated various software technologies in order to scale the computation of shape modifications in a distributed cluster of nodes. Although I generally focus more on the back end, in this project I worked as a full-stack developer, as I also coded a desktop application based on Qt framework.
Sandbox for Malware Multi-analysis
The project is composed of various back ends (one for each integrated security solution) and a REST API that receives analysis requests and schedules required Celery tasks. I also implemented a Slack bot that enables analysts to efficiently communicate with the platform and share analytic results with other members of the team.
