EC-COUNCIL EC0-350 Online Questions & Answers

• Question 691:

  NetBIOS over TCP/IP allows files and/or printers to be shared over the network. You are trying to intercept the traffic from a victim machine to a corporate network printer. You are attempting to hijack the printer network connection from your

  laptop by sniffing the wire.

  Which port does SMB over TCP/IP use?

  A. 443
  B. 139
  C. 179
  D. 445
  D. 445

• Question 692:

  During the intelligence gathering phase of a penetration test, you come across a press release by a security products vendor stating that they have signed a multi-million dollar agreement with the company you are targeting. The contract was for vulnerability assessment tools and network based IDS systems. While researching on that particular brand of IDS you notice that its default installation allows it to perform sniffing and attack analysis on one NIC and caters to its management and reporting on another NIC. The sniffing interface is completely unbound from the TCP/IP stack by default. Assuming the defaults were used, how can you detect these sniffing interfaces?

  A. Use a ping flood against the IP of the sniffing NIC and look for latency in the responses.
  B. Send your attack traffic and look for it to be dropped by the IDS.
  C. Set your IP to that of the IDS and look for it as it attempts to knock your computer off the network.
  D. The sniffing interface cannot be detected.
  D. The sniffing interface cannot be detected.

• Question 693:

  How would you describe an attack where an attacker attempts to deliver the payload over multiple packets over long periods of time with the purpose of defeating simple pattern matching in IDS systems without session reconstruction? A characteristic of this attack would be a continuous stream of small packets.

  A. Session Hijacking
  B. Session Stealing
  C. Session Splicing
  D. Session Fragmentation
  C. Session Splicing

• Question 694:

  A security administrator notices that the log file of the company`s webserver contains suspicious entries:

  

  Based on source code analysis, the analyst concludes that the login.php script is vulnerable to

  A. command injection.
  B. SQL injection.
  C. directory traversal.
  D. LDAP injection.
  B. SQL injection.

• Question 695:

  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. Rogue security software is based on social engineering technique in which the attackers lures victim to visit spear phishing websites
  D. This software disables firewalls and establishes reverse connecting tunnel between the victim's machine and that of the attacker
  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.

• Question 696:

  You are attempting to crack LM Manager hashed from Windows 2000 SAM file. You will be using LM Brute force hacking tool for decryption. What encryption algorithm will you be decrypting?

  A. MD4
  B. DES
  C. SHA
  D. SSL
  B. DES

• Question 697:

  Why would an ethical hacker use the technique of firewalking?

  A. It is a technique used to discover wireless network on foot.
  B. It is a technique used to map routers on a network link.
  C. It is a technique used to discover the nature of rules configured on a gateway.
  D. It is a technique used to discover interfaces in promiscuous mode.
  C. It is a technique used to discover the nature of rules configured on a gateway.

• Question 698:

  On a Linux device, which of the following commands will start the Nessus client in the background so that the Nessus server can be configured?

  A. nessus +
  B. nessus *s
  C. nessus and
  D. nessus -d
  C. nessus and

• Question 699:

  Bob was frustrated with his competitor, Brownies Inc., and decided to launch an attack that would result in serious financial losses. He planned the attack carefully and carried out the attack at the appropriate moment.

  Meanwhile, Trent, an administrator at Brownies Inc., realized that their main financial transaction server had been attacked. As a result of the attack, the server crashed and Trent needed to reboot the system, as no one was able to access

  the resources of the company. This process involves human interaction to fix it.

  What kind of Denial of Service attack was best illustrated in the scenario above?

  A. Simple DDoS attack
  B. DoS attacks which involves flooding a network or system
  C. DoS attacks which involves crashing a network or system
  D. DoS attacks which is done accidentally or deliberately
  C. DoS attacks which involves crashing a network or system

  Which one of the following statements is probably true?

  A. The systems have all ports open.
  B. The systems are running a host based IDS.
  C. The systems are web servers.
  D. The systems are running Windows.
