The Stairwell Extension is a free Chrome add-on designed to improve web security by highlighting MD5, SHA-1, and SHA-256 hashes on any web page. This tool allows users to instantly identify potential threats embedded within blogs, threat reports, or other web content. With just a couple of clicks, users can check if a file exists in their Stairwell environment, making threat assessment quick and efficient.

In addition to highlighting hashes, the extension integrates seamlessly with Stairwell's Run-to-Ground (RTG) feature, providing deeper file analysis and context for each potential threat. This functionality enables users to uncover sightings and variants, enhancing their overall security workflow. By facilitating immediate hash identification and search capabilities, the Stairwell Extension empowers users to make informed decisions and take decisive action to mitigate risks.
