2021 Congressional App Challenge

This year’s winning app, PhishByte, detects if a message or email is malicious, alerts the user, and flags malice for later reference. The app also allows the user to manually insert and check potentially malicious links, allowing the user to hover over the link and view details and a rating of the link on a green (safer) to red (not safe) scale. To authenticate links and keep users safe, PhishByte uses a python-based machine running algorithm, leveraging the tools and mathematical functions in the NumPy library. To learn more, click here.

Challenge winners from across the country will be invited to present their apps to Members of Congress at the #HouseOfCode Festival this spring. At that time, all winning apps will be featured in the U.S. Capitol Rotunda for one year.

At Tuesday’s ceremony, each team had the opportunity to present their app to Congresswoman Salazar and other functionaries from Florida’s 27th CongressionalDistrict. Following the presentations, the Congresswoman announced the winning app and honored each of the teams with Certificates of Special Congressional Recognition. Additionally, Congresswoman Salazar has committed to matching each team with a mentor to provide vital feedback and guidance as students work to bring their apps to market.
