What are OTP bots and how are they sold?

Question

Accepted Answer

OTP Bots are Malicious Programs Used to Steal One-Time Passwords

One-time password (OTP) bots are sophisticated malicious computer programs designed specifically to intercept the one-time passwords used in two-factor authentication systems. These bots can be purchased by scammers over the internet, enabling them to automate the process of stealing sensitive login credentials. The bots operate by directly calling potential victims, using pre-prepared scripts to deceive individuals into revealing their OTPs.
How OTP Bots Steal Passwords

The attack chain begins with hackers obtaining a victim's login credentials, frequently sourced from personal data breaches found on the dark web. Armed with this stolen information, the hacker initiates a login attempt on the victim's account, which triggers the sending of an OTP to the victim's phone. At this stage, the OTP bot takes over, initiating a call to the victim. The bot then follows a pre-scripted dialogue, aiming to persuade the victim to verbally share the one-time password. Hackers have the ability to configure the bot's language and voice, either male or female, to enhance the deception.
The Transmission of Stolen Codes

Once the victim divulges the OTP code to the bot, it is transmitted directly to the hacker. This occurs as the victim types the code into their phone, a process that does not interrupt the ongoing bot call. With the OTP in hand, the hacker can then input it to gain unauthorized access to the targeted online service or account. The availability of these bots for purchase online lowers the barrier to entry for individuals seeking to conduct such sophisticated phishing attacks.
The Sale and Customisation of OTP Bots

These advanced OTP bots are marketed and sold on the internet, making them accessible to a wider range of malicious actors. Scammers can acquire these tools and configure them to suit their specific attack strategies. This includes setting the language and voice of the bot to create a more convincing and personalized interaction with the intended victim. The fully-configurable nature of these bots allows for a high degree of customisation, increasing their effectiveness in bypassing security measures.
