Singapore Runs AI Scam Call “Fire Drills”

Singapore’s Cyber Security Agency is running a national exercise where volunteers receive simulated robocalls that mimic government impersonation scams, including AI-enabled calls. The article also points to real-world cases where criminals impersonated company executives on WhatsApp and even used digitally altered appearances on video calls to pressure victims into secrecy and compliance.

How the exercise and real attacks connect

Singapore's Cyber Security Agency (CSA) is running a six-month National Simulated Scams Exercise that sends volunteers robocalls mimicking government impersonation scams. CSA has said the pilot includes AI-enabled government impersonation scam calls, which reflects a shift toward more conversational and interactive scam tactics rather than static, scripted robocalls. This exercise is being paired with public warnings from Singapore Police about real cases where criminals impersonated company executives on WhatsApp, and in some instances used digitally altered appearances during video calls.

Why the executive impersonation tactic works

The scenario described by Singapore Police centers on a manipulation tactic built around secrecy. Victims were told they were working on confidential projects and instructed not to discuss the matter with colleagues. This single instruction is powerful because it removes the easiest way a target could catch the deception: asking a coworker or manager if the request is legitimate. Combined with impersonation of a senior executive and communication over WhatsApp instead of normal corporate channels, the setup creates pressure and isolation at the same time.

Red flags to watch for

  • A request to keep a project or instruction secret from colleagues
  • Executive-style requests arriving over WhatsApp rather than established corporate channels
  • Urgency or authority cues designed to short-circuit normal verification steps
  • Voice or video communications that feel unusually convincing or interactive, which may indicate AI-enabled or manipulated media

Building resistance across channels

The awareness takeaways from this case point to training that goes beyond email-based phishing awareness. Employees may now encounter a WhatsApp message supposedly from an executive, a convincing phone call from someone claiming to be IT, or a video call featuring a digitally manipulated face. Because voice-based social engineering can put victims under real-time pressure by exploiting authority, urgency, and fear, organizations are encouraged to build practical habits rather than rely on awareness alone.

The stated objective of exercises like this one is not to catch employees making mistakes, but to build a reflex: stop, verify, and use a second channel before acting. Practicing this response in a safe, simulated setting, sometimes called a fire drill approach, can help employees internalize the habit so they are more likely to apply it when a real attempt arrives through a phone call, video call, or messaging app.

Read the video transcript

Singapore is literally running scam-call fire drills because AI scam calls are now that convincing. Now picture this: a WhatsApp from your ‘CFO’, then a video call where their face looks right, and they say, “This is a confidential project, don’t tell anyone, just follow my instructions.” That secrecy line is the trick. Singapore Police say victims were told they were on confidential projects and cut off from colleagues, that’s how the scam works, not a sign you’re trusted. Your move: the moment someone says, “Keep this secret, reply only here,” stop and verify through normal channels, Teams, corporate email, or a known number, not WhatsApp.
