How the Windows Phone Link app works
Windows Phone Link is a free Microsoft app that lets folks view and entry telephone calls, textual content messages and notifications from their smartphone immediately on their Windows 10 or 11 PC. In the previous, the app has supported simply Android telephones, however a current replace from Microsoft permits Windows 11 customers to arrange Phone Link to work with sure fashions of iPhones.
Setting up Phone Link requires bodily entry to the telephone and to a Windows pc. The danger right here is that an individual who’s in a position to even quickly seize another person’s telephone might allow Phone Link on their very own Windows PC and use the app to spy on the sufferer’s telephone calls and textual content messages with out their information or permission.
Activating Phone Link is a comparatively easy course of, even with an iPhone.

How Android telephones might be exploited this fashion
Android telephones may also be exploited this fashion; nonetheless, there are a few variations between Android and iOS gadgets.
“This method can also be used against Android phones, and you can see more data from the phone too, for example, Photos,” Certo co-founder Simon Lewis mentioned. “However, it’s much easier to spot on Android for a few reasons. Firstly, the Link to Windows app must be installed from the Play Store. Secondly, a notification is shown on the phone when a connection to a computer is active.”
To be clear, this isn’t a course of that might be completed remotely — it does require that the individual have bodily entry to the sufferer’s telephone. Therefore, this isn’t a risk posed by nameless cybercriminals. Rather, that is extra one thing {that a} stalker might doubtlessly pull off, which means a member of the family, partner or vital different who needs to spy on somebody they know.
What Apple and Microsoft might and will do
Though the Phone Link app for each Windows and iOS is designed to assist customers, there’s this potential for abuse. With that in thoughts, Certo suggests a few steps that each Apple and Microsoft can take to warn customers of a possible risk.
With iOS 14 and better, your iPhone shows a inexperienced or orange dot on the high of the display when your microphone or digital camera is getting used. Apple might develop the same visible clue that will inform folks when notifications or messages are being shared with a Bluetooth-connected system. Microsoft’s choices are extra restricted, however the firm might add a warning to the Phone Link app that it ought to solely be used with your personal gadgets and never these of different folks.
Note: I contacted Microsoft and Apple for remark, however I didn’t obtain replies from both firm previous to publication.
