refers to the source code of an open-source tool designed to automate "vishing" (voice phishing) attacks to intercept sensitive user data, specifically One-Time Passwords (OTPs) . Overview and Functionality
: It exploits the trust users place in official-sounding voice calls. SMSBotBypass-master.zip
: The prevalence of such tools has led organizations like NIST and CISA to advise against using SMS as a primary second factor for authentication, citing its lack of encryption and susceptibility to interception. Recommended Protections refers to the source code of an open-source
The tool operates as an API connecting a threat actor's account with a Discord bot interface. This setup allows even low-skilled attackers to initiate automated robocalls to victims. Attack Sequence : Recommended Protections The tool operates as an API
The inputted data is captured by the bot and sent in plain text back to the attacker's Discord channel.
: Even if an attacker has stolen a password, the OTP remains a barrier; this tool provides a scalable way to bypass that final layer of security.
To defend against these automated bots, security experts recommend several measures: Analysis of attacks on SMS OTP-based authentication process
