This month, researchers found a new strain of Android malware that poses as the phone's own security tool and quietly switches it off. From there it reaches into the logins for 217 banking and finance apps. It does not care whether the phone it lands on is for work or for home. The people who built it are counting on one thing: that for most people, it is both.

Watch an ordinary Tuesday. The phone that checks personal email opens the work inbox too. A client file gets dropped into a free app to clean it up. The phone joins the office wifi the moment it is in range. All of it is normal, and none of it passes through anything you can see.

That is the gap. A device you cannot see still reaches the email, the files, and the network you answer for. And it is already where the leaks start: when stolen company logins surface in criminal hands, they come from personal, unmanaged devices nearly half the time, more often than from company machines, according to Verizon's annual breach report. Put one bad app on that phone, and the trouble does not stay personal.

The fix is a boundary, not a ban. Decide what company data is allowed onto a personal phone. Keep the rest on devices you control. Make the managed way the easy way, because people take the easy way.

You cannot secure a device you refuse to see.
