Freshko: Lightweight Open-Source Tool for Local File, Link and Miner Checks Released
Developer kozliq has released Freshko, a compact 400×640 desktop application written in Rust that performs quick local security checks on files, URLs and running processes without uploading data to third-party services. The tool uses on-device YARA-X rules for file scanning, follows URL redirects while querying Cloudflare’s filtering DNS, and scores processes for mining indicators using weighted rules rather than CPU load alone. It deliberately avoids sending files anywhere and keeps link checks private except for the necessary DNS queries to Cloudflare’s 1.1.1.2 and 1.0.0.2 resolvers. Freshko explicitly reports what it could not scan due to size limits, permissions or timeouts instead of falsely claiming a clean result. The project is fully open source, available for macOS and Windows, and positioned as a fast first-look utility rather than a replacement for commercial antivirus or URL scanners.
