is the source code for an open-source tool designed to automate vishing (voice phishing) to steal one-time passwords (OTPs). Originally posted to GitHub by a user named "Ross1337" in December 2020, the project was officially removed in February 2022, though multiple copies continue to circulate on Telegram and other forums.
