The Conficker Virus is Windows only but it’s garnering a lot of attention, so if you’re on a Windows LAN at home, work, or school, you may want to check if the Windows machines are vulnerable or infected with Conficker. You can do this from your immune Mac OS X machine pretty easily with a cool command line utility called nmap. Here are the steps:
1) First you need to install the command line tool nmap
2) Use nmap to search your LAN for vulnerabilities to Conficker by using the following command:
nmap -PN -T4 -p139,445 -n -v –script=smb-check-vulns –script-args safe=1 192.168.0.1-254
Note: Be sure to substitute the IP range for your LAN, so this may be something other than the IP range above, like 10.1.1.10-100 3) Examine the output of nmap, you are looking for something like this to tell if you have a problem:
