Alert: Linux/Lupper.worm

Publication:McAfeeDate:Nov 07 2005

Advertisement
This worm spreads by exploiting web servers hosting vulnerable PHP/CGI scripts. It is a modified derivative of the Linux/Slapper and BSD/Scalper worms from which it inherits the propagation strategy. It scans an entire class B subnet created by randomly choosing the first byte from an hard-coded list of A classes and randomly generating the second byte.
