- # jwl notes:
- # several reasons to have a separate check for this worm
- # 1) IT shops are going to be running 1-off scans just for this worm
- # 2) variants are sure to come...this way, we just update variants below
- # 3) while there is a network-based check for this worm, many smarter companies
- # will stop propogation of the worm by blocking 5554 and 9996 on core switches
- # and routers
