• Question 651:

  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?

  A. A flash file extension to Firefox that gets automatically installed when a victim visits rogue software disabling websites

  B. A Fake AV program that claims to rid a computer of malware, but instead installs spyware or other malware onto the computer. This kind of software is known as rogue security software.

  C. A Fake AV program that claims to rid a computer of malware, but instead installs spyware or other malware onto the computer. This kind of software is known as rogue security software.

  D. A Fake AV program that claims to rid a computer of malware, but instead installs spyware or other malware onto the computer. This kind of software is known as rogue security software.

  E. Rogue security software is based on social engineering technique in which the attackers lures victim to visit spear phishing websites

  F. This software disables firewalls and establishes reverse connecting tunnel between the victim's machine and that of the attacker
