Scam Advice (Abuse of OTT Messaging Channels)

Abuse of OTT Messaging Channels

The same scams once confined to SMS now run through WhatsApp, Telegram, iMessage, and other messaging apps — often with added credibility from group chats, verified-looking business accounts, or cloned profile photos of people you know.

Three boxes explain scam techniques: “A message outside SMS” uses a known app; “Borrowed trust” uses a cloned contact photo; “Money or credentials” tricks into sending money with urgency. Each box has example text and a brief description. White background, red accents.

How the scam works

Scammers rely on urgency and trust. They create time pressure so you act before verifying, and they impersonate a sender you’d normally trust without a second thought.

How to protect yourself

A young woman with long hair, wearing a light green jacket and a rucksack, stands under a large arched roof structure. She is looking down at her mobile phone, with hair gently blowing, and other people and blurred architectural details in the background.

If you think you’ve been targeted

  1. Don’t send money or personal details until you’ve verified the person independently
  2. If money was sent, contact your bank immediately
  3. Report the account/profile to the messaging platform
  4. Warn mutual contacts if a cloned profile is being used
  5. Report to your national fraud reporting body
