When browsing GitHub, be wary of "red flags" in repositories claiming to offer paid software for free:

: Be skeptical of repositories hosted by accounts created very recently with no other contributions.

🚩 : Always run suspicious tools in an isolated, "air-gapped" virtual machine if you are performing research, and never use them on a production network. Do you need to scan web apps or network hardware ?

: A modern, template-based scanner that is highly popular among bug bounty hunters. It is open-source and has a massive community-driven library of templates.

GitHub repositories promising "cracked" versions of Nessus are prime delivery vehicles for trojans. Attackers often embed scripts that grant them remote access to the machine running the scan. Since a vulnerability scanner requires high-level system permissions to operate, a compromised version gives an attacker full administrative control over your network. Outdated Vulnerability Plugins
