The Cheese worm: A welcome helper?
System administrators worldwide reported signs Wednesday that another self-spreading
program--or worm--had started to infect Linux systems.
This worm appears to be different, however: Dubbed the Cheese worm, the program is basically a self-spreading patch. It enters servers that have already have been compromised by a previous bit of malicious code--the 3-month-old 1i0n worm--and closes the back door behind it, adding security to the system.
