Penetration testing with a single beagle 119 FIGURE 5.21 LAN Manager passwords cracked with John the Ripper. The appropriate command to crack these passwords is john –wordlist¼/pentest/ password/wordlists/rockyou.txt hashdump.txt. John will output the passwords it finds. You can also list passwords later using john –show hashdump.txt. The output from running john is shown in Figure 5.21. Note that LAN Manager passwords are cracked in two separate parts and are not case-sensitive. Windows converts passwords to upper case and truncates them to fourteen characters. The LAN Manager passwords are particularly vulnerable because the first and last seven characters are hashed separately. The user Bob has a password of “JessicaAlba” and Phil has a password that starts with “moneymo”. After some intelligent guessing, Phil’s password is found to be “moneymoney”. Because the Linux computer at 192.168.10.101 has no vulnerable services, the only practical way to attack this box is to crack user passwords. This presents a challenge as we know one user account, root, with certainty. Based on the OpenVAS scan, the machine appears to run some flavor of Ubuntu so we might also try the username ubuntu. A successful password crack for the ubuntu user is shown in Figure 5.22. Once we have a foot in the door with the ubuntu log-in, we can download the /etc/ passwd file in order to get additional usernames for cracking more passwords. We can also try our luck with a sudo -s command from the ubuntu log-in. If we are fortunate, the user will be in the sudoers list and we will be prompted for the known ubuntu password and not the root password. Once logged in as root, there is little we can’t do including downloading the /etc/shadow file. While it might seem strange to crack passwords after obtaining root access, many people reuse the same password on multiple systems.
120 CHAPTER 5 Powering The Deck FIGURE 5.22 Cracking passwords with Hydra and SSH service. DETECTING OTHER SECURITY ISSUES We have cracked the wireless password, identified and exploited a vulnerability on the Windows XP machine, cracked the router password, cracked a few passwords on the Windows XP box, and gained access to the Linux machine as well. The penetration test is far from over, however. One of the more useful things that we can do during our test is to sniff the network traffic. Sniffing traffic between the tablets used by employees and the servers reveals that access to the company intranet site hosted on the Linux machine is unencrypted. This presents a huge security hole as log-in credentials and other sensitive information are easily obtained. A fair amount of instant messaging and visits to inappropriate Web sites are also detected. The instant messaging is concerning as it might involve leaking of sensitive information. Inappropriate Web sites are a hotbed for malware that might lead to a security breach at PFE. The company intranet site should be investigated. The first step is to use a Web vulnerability scanner such as Nikto (http://www.cirt.net/Nikto2). Running nikto -host 192.168.10.101 will run a basic scan against the intranet site. Nikto failed to discover any issues with the Apache 2.2 Web server installation or the intranet
