One of the easiest ways for a scammer to succeed is to look like someone you already trust.
That's why this WhatsApp change is worth paying attention to 👀
Usernames have become more widely available, and security researchers are warning about the potential for impersonation.
The concern is that criminals could create usernames that look very similar to a real colleague, supplier, customer or business leader and use them to start conversations that appear real.
This isn't really a WhatsApp problem.
But the technology creates another opportunity for someone to pretend to be somebody else.
I think this is a good reminder to think carefully about where work conversations should happen.
If employees are discussing projects, sharing documents, approving payments or making important decisions through personal messaging apps, it’s much harder to verify who you're talking to.
That's one of the reasons platforms like Microsoft Teams exist.
They're designed for business communication, with user accounts managed by the organization, security controls in place, and much better visibility if something unusual happens.
WhatsApp has its place.
It's great for chatting with friends and family, and many businesses use it for customer communication.
But be very cautious about relying on it for internal business conversations. Especially where money, confidential information or important decisions are involved 🤐
Whatever messaging platform you use, remember that names, profile pictures and usernames prove very little on their own.
If somebody asks you to change bank details, buy gift cards, share sensitive information or approve an urgent payment, don't rely on the message itself to tell you it's genuine.
Pick up the phone, start a new Teams chat, speak to them in person or use a contact method you already know belongs to that individual.
That simple habit prevents a huge number of scams.
As criminals become better at impersonating real people, independently verifying unusual requests is becoming one of the most valuable security habits a business can develop.
