Joseph was the Web site administrator for the Mason Insurance in New York, who's main Web site was located at www.masonins.com. Joseph uses his laptop computer regularly to administer the Web site.
One night, Joseph received an urgent phone call from his friend, Smith. According to Smith, the main Mason Insurance web site had been vandalized! All of its normal content was removed and replaced with an attacker's message ''Hacker Message: You are dead! Freaks!
From his office, which was directly connected to Mason Insurance's internal network, Joseph surfed to the Web site using his laptop. In his browser, the Web site looked completely intact. No changes were apparent. Joseph called a friend of his at his home to help troubleshoot the problem. The Web site appeared defaced when his friend visited using his DSL connection. So, while Smith and his friend could see the defaced page, Joseph saw the intact Mason Insurance web site. To help make sense of this problem, Joseph decided to access the Web site using his dial-up ISP. He disconnected his laptop from the corporate internal network and used his modem to dial up the same ISP used by Smith.
After his modem connected, he quickly typed www.masonins.com in his browser to reveal the following web page:
H@cker Mess@ge:
Y0u @re De@d! Fre@ks!
After seeing the defaced Web site, he disconnected his dial-up line, reconnected to the internal network, and used Secure Shell (SSH) to log in directly to the Web server. He ran Tripwire against the entire Web site, and determined that every system file and all the Web content on the server were intact.

Michael is a junior security analyst working for the National Security Agency (NSA) working primarily on breaking terrorist encrypted messages. The NSA has a number of methods they use to decipher encrypted messages including Government Access to Keys (GAK) and inside informants. The NSA holds secret backdoor keys to many of the encryption algorithms used on the Internet. The problem for the NSA, and Michael, is that terrorist organizations are starting to use custom-built algorithms or obscure algorithms purchased from corrupt governments. For this reason, Michael and other security analysts like him have been forced to find different methods of deciphering terrorist messages. One method that Michael thought of using was to hide malicious code inside seemingly harmless programs. Michael first monitors sites and bulletin boards used by known terrorists, and then he is able to glean email addresses to some of these suspected terrorists. Michael then inserts a stealth keylogger into a mapping program file readme.txt and then sends that as an attachment to the terrorist. This keylogger takes screenshots every 2 minutes and also logs all keyboard activity into a hidden file on the terrorist's computer. Then, the keylogger emails those files to Michael twice a day with a built in SMTP server. What technique has Michael used to disguise this keylogging software?
