There really is an app for almost everything — including one that cyber-criminals use to hack into businesses’ systems. Cyber-attacks have become so advanced that they are now aided by an app, like this one, that poses serious threats to Office 365 users. If you’re using Office 365, here’s what you need to know.
The latest cyber attack on Microsoft Office 365 involves harvesting users’ credentials. Scammers use this previously unseen tactic by launching a phishing message to users, asking them to click on an embedded link. What makes this scam more insidious than traditional phishing scams is that the URL within the message links to a real Microsoft login page.
The phishing message resembles a legitimate SharePoint and OnEDRive file-share that prompts users to click on it. Once they do, they are taken to an Office 365 login page, where they will be asked to log in if they haven’t already.
After they’ve logged in, they’ll be prompted to grant permission to an app called “0365 Access.” Users who grant permission effectively give the app — and the hackers behind it — complete access to their Office 365 files, contacts, and inbox.
This technique can easily trick lots of users since the app that requests access is integrated with the Office 365 Add-ins feature. That means that Microsoft essentially generates the request for permission. No, Microsoft is not aiding hackers to breach systems. Rather, the scam is made possible by a feature that allows users to install apps that aren't from the official Office Store.
Given their fairly advanced approach, these scammers could effortlessly prey on careless employees. There are ways to make sure that doesn’t happen.
Successful attacks could result in an unimaginable catastrophe for your company. For tips on spotting this and other nefarious scams and how to plan thorough security practices, contact our experts today.
