The Threatcop Security Awareness Training (TSAT) is growing its social engineering simulation engine with a new AI‑driven phishing attack vector. This new update allows organizations to replicate a real-world vishing attack in which targeted users receive a call (or call‑like communication) seemingly from a reliable source and are socially engineered by an AI-powered voice agent.

ToggleThis vector ranged beyond typical phone calls. It arrived as a notification, then transitioned to a more conversational experience, in which an AI agent engaged users in a natural, human-sounding dialogue via WhatsApp that mimics how attackers actually behave.
What is Vishing?
Vishing (voice phishing) is a form of social engineering that uses the telephone or other voice-based communication. In a vishing attack, the attacker, who impersonates a trusted authority, may be a bank, IT support team, HR department, or some other government-style agency, and attempts to persuade the user to reveal information like PINs, passwords, one‑time passwords, or account information by making them believe that he is a trusted authority.
In modern vishing attacks, attackers often use AI‑powered voice agents or interactive systems that mimic real‑life customer service flows, making the interaction feel natural and urgent. Customer sentiments or emotions can be articulated and exploited to sound authentic, pre-dominate, and be compelling, thereby making them much more difficult for users to identify as deceptive. Threatcop‘s vishing simulation replicates this call flow in a one-of-a-kind environment so that organizations can train their teams in a safe virtual environment with no real-world implications.

The aim of the Vishing Attack Vector
The purpose of this attack vector is to emulate a real-world vishing situation in which users receive a genuine-appearing voice‑style communication or phone call from a trusted organization or person.
During this simulation, the AI‑enabled voice agent will accurately conduct social engineering conversations, allowing organizations to:
- Identify how users react as if they were talking to a trusted authority.
- Now that‘s where you‘d least expect them to share things which really matter…
- To measure a user‘s fear/behavior/perception by providing clear metrics in a safe environment.
The idea is to go beyond the typical email-only phishing tests and raise employee awareness of voice-driven social engineering attacks, which are becoming more prevalent.
Step‑by‑step execution flow
The phishing simulation in Threatcop Security Awareness Training follows a standard 4‑step process, as in every vishing attack. It initially sends you a notification and keeps transferring into an interactive conversation.
Step 1: Template creation
The foundation of the vishing simulation is template creation. In this step, the admin:
- Creates a phishing template that specifies the simulation’s overall architecture and functioning.
- Configures the AI‑driven WhatsApp conversation by setting:
- Response logic: How the AI should respond to different user inputs.
- Tone: Whether the agent behaves formally, friendly, urgent, or supportive, matching the impersonated brand or team.
- Interaction paths: The flow of questions and prompts triggered by user actions (for example, what happens when the user asks for more details, or tries to hang up or stop the conversation).
This setup will make the AI agent behave in a realistic, socially engineered manner by closely simulating how an attacker would guide a user through a vishing attack.
Step 2: Campaign creation
When the campaign is ready, the admin will create it using the AI‑powered vishing template.
- Choose the user group to target, such as HR, finance, a specific department, or a region.
- The campaign is scheduled/ launched right away as per requirements.
- The connection between the template selected, the activation of the campaign, and the system for delivering messages, which generally begins with an email to this email, which will now serve as the gateway into the WhatsApp‑based AI conversation.
We now have the simulation set up and are ready to start the real-world type flow of vishing.
3. User simulation and Chatbot for AI WhatsApp:
This phase is where the attack vector takes off, and it’s most likely a real-world vishing attempt that starts with a notification and evolves into a conversational channel.
The end user receives an email that appears to originate from a reputable, widely used company, such as a bank, a credit card company, or an internal service team.
Key characteristics of this email include:
- It is from a trusted sender, with a valid sender name and domain.
- It delivers a reward, a voucher, a refund, or an account-related message, something the user finds familiar and relevant.
- It uses language of urgency like “limited time”, “action required”, or “verify your account now”.
- When it has a single call‑to‑action (CTA) button, e.g.: {{.whatsappCta}}.
This is the user’s interaction with the simulation, where they begin the next step in the phishing flow.
When the user clicks the CTA:
- They are sent to: web.whatsapp.com.
- A WhatsApp chat window appears with the same number opening that is embedded as a ‘brand support’ or ‘rewards team’ number.
- The attacker profile, including the WhatsApp number and display name, will match the brand (or sender) mentioned in the email to appear legitimate.
The goal of this step is to direct the user to a more commonly used messaging application. Since we use WhatsApp so often for fake customer care interactions, users tend not to be suspicious.
Step 4: Response monitoring and analysis
Following the simulation going live, the system is now in the stage of entering response measurement and analysis.
- While the WhatsApp conversation is taking place, the user’s responses will also be observed.
- It also monitors when questions are answered, how long it takes a user to respond, and whether the user discloses private information.
- The system decides if someone has been “compromised” in vishing based on how much and how detailed the information they reveal is, regardless of whether it’s real or made up, including the last four digits, employee ID, or the type of verification questions.
Admins can then:
- Review the way users tend to behave when they believe that they are “talking” to a trustworthy voice‑style authority.
- Apply this behavioral knowledge to adapt your training materials, adjust campaign settings, or identify and focus on higher-risk individuals or teams.
Why Does this Capability Matter?
However, by offering AI‑enabled phishing simulations for Threatcop TSAT, companies would arm their employees with the tools to navigate emerging threats. Vishing is no longer a niche tactic; it’s a mainstream attack method that exploits trust, crisis, and familiar communication tools.
This new vector allows security teams to:
- To demonstrate safe real‑world vishing‑style interactions. Employees will be able to simulate a think‑like‑the‑attacker attack in a controlled environment.
- Apply semantic measures to quantify user behavior, such as disclosure rate and engagement-versus-caution behavior.
- Use these findings to create focused training, reminders, and reinforcement modules for the most at-risk teams and individuals.
This functionality enables Threatcop to help organizations set aside static phishing tests and implement a continuously changing, intelligence‑driven security awareness program aligned with how today‘s attackers operate and how employees would actually react.
FAQs
What is a vishing attack, and how does it work?
A vishing attack is a phone- or voice-based phishing scam that attempts to trick users into disclosing sensitive data, such as PINs, passwords, or account information, by posing as a trusted caller or message.
What are the steps that companies can take to educate their staff about a vishing attack?
Users are trained to identify and resist vishing attacks through realistic vishing simulation exercises, clear instructions for verifying the caller's identity, and regular awareness modules that emphasize the need to be vigilant, avoid fake authority, and recognize social engineering cues.
Why is vishing attack training important for security awareness?
Vishing attacks are a new, mainstream attack vector that exploits trust and urgency. A safe vishing simulation environment enables organizations to gain insights into vulnerabilities, improve training, and minimize risk.
What makes vishing attacks more dangerous with the help of AI?
Vishing attacks can sound more convincing and harder to detect thanks to AI-powered voice agents that can replicate real customer service interactions, adopt a natural tone and urgency, and adapt on the fly.
Can Threatcop simulate a vishing attack for security awareness training?
Yes. Threatcop’s Security Awareness Training includes an AI‑powered vishing attack simulation that starts with a trusted‑looking email and moves into a WhatsApp‑based, AI‑driven conversation to test how users respond.
