A：Hey, Cory....did you hear about the break-in?  

B：No! Burglars broke in? Did they steal anything valuable?  

A：Actually, they might have gotten quite a bit of valuable information. But it wasn't thieves, it was online hackers.  

B：Ah, so somebody broke into our computer system! Oh, good morning, Brenda. Did you hear the news? There was a cyber attack!  

C：Oh my! But I thought we had very strong Internet firewalls.  

A：We do, but all it takes is one mistake and hackers can come pouring in like an invading army.  

B：Does the I.T. department have any idea how this happened?  

A：It looks like the hackers got in from an unsecure corporate e-mail account.  

B：And then they loaded up a virus?  

A：Not a virus, but they put spyware or malware into our system.  

B：I've heard of spyware but what's malware?  

C：Malware is short for "malicious software." Malware is any kind of software that is specially designed to infiltrate a computer system.  

B：So spyware is a kind of malware.  

C：Sometimes the malware follows each keystroke you make, and then sends the information back to the hacker.  

A：Or, sometimes they install a program called a Trojan horse that steals data.
