This computer was left unlocked.
That is dangerous.
When a computer is unlocked, anyone can walk up and plug in a small USB device. This can happen in less than one second.
A bad person could:
• steal passwords
• watch your screen
• see what you type
• turn on your camera
• listen through your microphone
• control your computer
They could also install ransomware.
Ransomware can:
• lock your files
• destroy important work
• spread to other computers on the network
• shut down an entire school or workplace
This has happened before.
Right now, nothing bad was done.
This message is proof of how fast it could happen.
Two seconds is all it takes.
