Hi,

this is Mallory Malicious from the IT security company. You know, I'm responsible for improving your network's safety. Excuse me for using your time, but I have changed the security mode. Now all users have to be updated if they are to have access again. Would you please give me your user name and password, so I can adjust your account properly?

Thank you very much

Obtained user name and password for access on foreign network.

Hi Alice,

have you heard of this horrible ABC virus? I have been infected! All my files were deleted. It's a total chaos.

If you have this virus you MUST delete it! It hides in your C:\WINDOWS\SYSTEM folder. Look there and delete the EMM386.exe!

Be sure to post this mail to all your friends, too! They might be infected.
