NCSC Warns Against Growing Messaging App Cyber Attacks!

Messaging apps like WhatsApp, Facebook Messenger and Signal are a huge part of everyday communication — both personally and professionally.

But according to the National Cyber Security Centre (NCSC), they’re also becoming a growing target for cyber attacks, especially against individuals with access to sensitive information.

Who’s Most at Risk?

Some people are more likely to be targeted than others.

You might fall into a higher-risk category if:

• You have access to sensitive business or government data
• You’re in a position of influence or authority
• Your role connects you to high-value contacts or systems

In short — if your account is useful to someone, it becomes a target.

Common Attack Tactics

Attackers don’t need to hack systems — they often just trick people instead.

Here’s what to watch for:

• Requests for login or recovery codes
• Unknown devices being linked to your account
• Unexpected people appearing in group chats
• Messages pretending to be from someone you know
• Suspicious links or QR codes designed to steal information

If something feels off, it usually is.

How to Protect Yourself

The NCSC recommends some straightforward steps to reduce your risk:

• Don’t share sensitive information over messaging apps
• Use work-approved apps and devices for business communication
• Never share verification codes or scan random QR codes
• Turn on two-step verification (or Registration Lock on Signal)
• Enable passkeys where available
• Check linked devices regularly and remove anything unfamiliar
• Review group chats and verify unknown participants
• Watch out for duplicate or impersonated contacts
• Use disappearing messages on personal accounts to limit exposure

None of this is complicated — but skipping it makes you an easy target.

Final Thoughts

Social engineering attacks are getting smarter, and messaging apps are now a key entry point.

This guidance comes directly from the National Cyber Security Centre (NCSC), which also offers further advice for high-risk individuals — including steps to improve personal cyber resilience and secure communications.

If you’re handling anything even slightly sensitive, it’s worth taking this seriously.
