Aleff

Alessandro Greco developed cross-platform payloads and privacy-enhancing scripts for the hak5/usbrubberducky-payloads repository, focusing on both Windows and macOS environments. He engineered payloads with OS detection, readiness checks, and telemetry integration, using Bash, DuckyScript, and shell scripting to automate exfiltration and user-agent randomization via Tor. His work included refactoring scripts for reliability, consolidating code to reduce maintenance, and documenting anti-forensics techniques to support security awareness and threat modeling. Alessandro’s contributions demonstrated depth in payload development, network security, and technical writing, providing defenders with clear guidance and artifacts for detection tuning while maintaining a clean, maintainable codebase.

February 2025 performance highlights for hak5/usbrubberducky-payloads. Focused on delivering a privacy-oriented User-Agent (UA) randomization payload, repository cleanup, and script reliability improvements. Business value centers on cleaner codebase, reduced maintenance overhead, and more dependable payload deployment. Key outcomes: - Startup-ready Chrome UA randomization payload: DuckyScript kicks off a Bash script that fetches a random UA via Tor and curl, updates the Chrome launcher to run the script on startup, and includes an option to erase history. - Codebase consolidation: cleaned up related files and removed duplicates to improve maintainability and reduce operational risk. - Script reliability improvements: refactored payload script and updated hotkey handling to improve compatibility (STRINGLN usage for notepad.exe and ALT+F hotkey).
