Scams powered by artificial intelligence are no longer a distant concern, and Malaysian police are now warning the public about a worrying new method known as the "silent call" voice exploitation scam. The Royal Malaysian Police (PDRM) issued the alert after a Kuala Lumpur police officer explained the tactic in a video that quickly spread on TikTok.

Unlike traditional scam calls that rely on scripted conversations, this approach is far more subtle and dangerous. It doesn't start with threats or demands. Instead, it begins with silence.

How the "Silent Call" Scam Works

According to Inspector Tai Yong Keong from the Cheras Commercial Crime Investigation Department, victims often receive phone calls that appear to connect normally but remain completely silent on the other end. Many people instinctively respond with a "Hello?" or a short greeting, unaware that those few seconds may be all scammers need.

That brief response, typically three to five seconds long, can be recorded and fed into AI voice-cloning tools. With just a short sample, modern AI can convincingly recreate a person's voice, including tone, pacing, and speech patterns.

Once the voice is cloned, scammers move to the next phase.

Turning a Voice Into a Weapon

After creating a fake version of the victim's voice, scammers may contact a family member while pretending to be the victim. They often claim to be in serious trouble, such as being detained, injured, or involved in an emergency that requires immediate financial help.

By sounding like someone familiar, the scammer increases panic and urgency. Victims' family members may feel pressured to act quickly and transfer money to a third-party account without verifying the situation. This emotional manipulation is what makes the scam particularly effective.

Inspector Tai described this tactic as an evolution of impersonation scams, made far more convincing by the use of AI technology.

What the Police Advise You To Do

To reduce the risk of falling victim, police are urging the public to change how they handle unknown calls. Inspector Tai advises against speaking first when answering calls from unfamiliar numbers. If the caller does not identify themselves or remains silent, the safest action is to hang up immediately.

Families are also encouraged to establish verification habits. Any urgent request for money, even if it sounds like it comes from a loved one, should be confirmed through another method such as calling the person directly, messaging them, or checking with another family member.

No Confirmed Cases Yet, But Stay Alert

Bukit Aman Commercial Crime Investigation Department director Datuk Rusdi Mohd Isa noted that police have not yet received confirmed reports of scams successfully using AI-cloned voices obtained through silent calls. However, he stressed that the lack of confirmed cases does not mean the threat should be ignored.

With AI tools becoming more accessible and powerful, authorities are urging the public to remain cautious, avoid sharing personal information, and verify suspicious calls through official or trusted channels.

A New Scam Era Driven By AI

This warning highlights how scams are evolving alongside technology. What once required long conversations and elaborate stories can now begin with just a few seconds of audio. As AI continues to advance, awareness and simple changes in behaviour, such as not responding to silent calls, may be the most effective first line of defence.
