And that word, `WANKED'. It did not make sense. What did it mean when a system was `wanked'?

It meant NASA had lost control over its computer systems.

A NASA scientist logging in to an infected computer on that Monday got the following message:

deleted file <filename1>

deleted file <filename2>

deleted file <filename3>, etc

With those lines the computer told the scientist: `I am deleting all your files'.

The line looked exactly as if the scientist typed in the command:

delete/log *.*

—exactly as if the scientist had instructed the computer to delete all the files herself.
