Savvy Fish

Savvy Fish is an anti-phishing solution designed to operate entirely within the user's browser, providing local protection against credential theft. Its primary function is to detect phishing sites before users enter their login information, aiming to prevent the theft of passwords and sensitive data. The tool works directly in the browser and does not rely on external servers, emphasizing user privacy and confidentiality.

The platform addresses the threat of phishing, where attackers create fake websites that closely mimic legitimate services such as banks, email providers, or delivery services. Savvy Fish intercepts these deceptive sites before they load, alerting users to potential risks. One of its key features is the detection of domains that imitate authentic ones, including those using visually similar characters or deliberate typographical errors, such as "rncrosoft.com" in place of "microsoft.com" or using Cyrillic characters that resemble Latin ones. Its analysis includes deterministic checks for typos, homoglyphs, and brand impersonation, as well as a machine learning model trained on a large dataset of real malicious URLs to evaluate potential threats.

Savvy Fish is intended for individuals seeking protection from phishing attempts while browsing the internet. It is delivered as a browser-based tool that users can add directly to their browser.
