The Ways Office 365 Phishing Can Happen

Office 365 is a popular office suite used by workplaces all over the world. Not only do Windows users utilize it, but iOS customers do as well.

That’s how versatile Office 365 is.

But just because it’s widely used doesn’t mean it doesn’t have its vulnerabilities. Windows has over 60 million commercial customers, which means cybercriminals are drawn to this enormous pool of potential victims.

You can avoid being an Office 365 phishing victim by learning what you need to watch out for. Read on and find out how you can identify phishing attacks.

Fake non-delivery emails

Office 365 phishing attacks are so effective because they masquerade as Microsoft. A fake non-delivery email from “Microsoft” looks harmless enough. It’s cleverly replicated so you don’t think twice about clicking on “send again.”

However, once you do, it’ll open a spoofed Office 365 login page. Your login credentials are then sent to the cybercriminals after you type them in. With this information, they’ll try other websites to see if they can access your accounts.

This non-delivery email scam is sophisticated since it involves a JavaScript function. This function sends your credentials to the scammers discreetly and redirects you to the genuine Outlook login page so you don’t suspect a thing.
