The most obvious place to start is with phone directories Many companies now sell libraries of local phone books on CD-ROM that can be used to dump into war-dialing scripts Many websites also provide a similar service as the Internet continues to become one big massive online library Once a main phone number has been identified, attackers may war-dial the entire exchange surrounding that number For example, if Acme Corp s main phone number is 555-555-1212, a war-dialing session will be set up to dial all 10,000 numbers within 555-555-XXXX Using four modems, this range can be dialed within a day or two by most war-dialing software, so granularity is not an issue Another potential tactic is to call the local telephone company and try to sweet talk corporate phone account information out of an unwary customer service rep This is a good way to learn of unpublished remote access or datacenter lines that are normally established under separate accounts with different prefixes Upon request of the account owner, many phone companies will not provide this information over the phone without a password, although they are notorious about not enforcing this rule across organizational boundaries Besides the phone book, corporate websites are fertile phone number hunting grounds Many companies caught up in the free flow of information on the Web will publish their entire phone directories on the Internet This is rarely a good idea unless a valid business reason can be closely associated with such giveaways Phone numbers can be found in more unlikely places on the Internet One of the most damaging places for information gathering has already been visited earlier in this book but deserves a revisit here The Internet name registration database found at http:// wwwarinnet will dispense primary administrative, technical, and billing contact information for a company s Internet presence via the WHOIS interface The following (sanitized) example of the output of a WHOIS search on acmecom shows the do s and don ts of publishing information with InterNIC:.

U NFS Countermeasure and related services (for example, mountd, statd, and If NFS is not required, NFS

Not only do attackers now have a possible valid exchange to start dialing, but they also have a likely candidate name (John Smith) to masquerade as to the corporate help

lockd) should be disabled Implement client and user access controls to allow only authorized users to access required files Generally, /etc/exports or /etc/dfs/dfstab or similar files control what file systems are exported and specific options that can be enabled Some options include specifying machine names or netgroups, read-only options, and the ability to disallow the SUID bit Each NFS implementation is slightly different, so consult the user documentation or related man pages Also, never include the server s local IP address or localhost in the list of systems allowed to mount the file system Older versions of the portmapper would allow attackers to proxy connections on behalf of the attackers If the system were allowed to mount the exported file system, attackers could send NFS packets to the target system s portmapper, which in turn would forward the request to the localhost This would make the request appear as if it were coming from a trusted host and bypass any related access control rules Finally, apply all vendor-related patches

Determining where mail is handled is a great starting place to locate the target organization s firewall network Often in a commercial environment, mail is handled on the same system as the firewall, or at least on the same network Therefore, we can use the host command to help harvest even more information:
