A Trojan horse is a destructive program that masquerades as a benign application. The software
initially appears to perform a desirable function for the user prior to installation and/or execution,
but in addition to the expected function steals information or harms the system.

The challenge for an attacker is to send a convincing file attachment to the victim, which gets
easily executed on the victim machine without raising any suspicion. Today’s end users are quite
knowledgeable about malwares and viruses. Instead of sending games and fun executables,
Hackers today are quite successful in spreading the Trojans using Rogue security software.
What is Rogue security software?

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.
How did the attacker accomplish this hack?
