Q1. You have successfully run a buffer overflow attack against a default IIS installation running on a Windows 2000 Server. The server allows you to spawn a shell. In order to perform the actions you intend to do, you need elevated permission. You need to know what your current privileges are within the shell. Which of the following options would be your current privileges?
A. Administrator
B. IUSR_COMPUTERNAME
C. LOCAL_SYSTEM
D. Whatever account IIS was installed with
Answer: C
Explanation: If you manage to get the system to start a shell for you, that shell will be running as LOCAL_SYSTEM.
Q2. In which of the following should be performed first in any penetration test?
A. System identification
B. Intrusion Detection System testing
C. Passive information gathering
D. Firewall testing
Answer: C
Q3. You want to hide a secret.txt document inside c:\windows\system32\tcpip.dll kernel library using ADS streams. How will you accomplish this?
A. copy secret.txt c:\windows\system32\tcpip.dll kernel>secret.txt
B. copy secret.txt c:\windows\system32\tcpip.dll:secret.txt
C. copy secret.txt c:\windows\system32\tcpip.dll |secret.txt
D. copy secret.txt >< c:\windows\system32\tcpip.dll kernel secret.txt
Answer: B
Q4. What does FIN in TCP flag define?
A. Used to close a TCP connection
B. Used to abort a TCP connection abruptly
C. Used to indicate the beginning of a TCP connection
D. Used to acknowledge receipt of a previous packet or transmission
Answer: A
Explanation: The FIN flag stands for the word FINished. This flag is used to tear down the virtual connections created using the previous flag (SYN), so because of this reason, the FIN flag always appears when the last packets are exchanged between a connection.
Q5. One of the ways to map a targeted network for live hosts is by sending an ICMP ECHO request to the broadcast or the network address. The request would be broadcasted to all hosts on the targeted network. The live hosts will send an ICMP ECHO Reply to the attacker source IP address.
You send a ping request to the broadcast address 192.168.5.255.
[root@ceh/root]# ping -b 192.168.5.255 WARNING: pinging broadcast address PING 192.168.5.255 (192.168.5.255) from 192.168.5.1 : 56(84) bytes of data. 64 bytes from 192.168.5.1: icmp_seq=0 ttl=255 time=4.1 ms 64 bytes from 192.168.5.5: icmp_seq=0 ttl=255 time=5.7 ms
There are 40 computers up and running on the target network. Only 13 hosts send a reply while others do not. Why?
A. You cannot ping a broadcast address. The above scenario is wrong.
B. You should send a ping request with this command ping 192.168.5.0-255
C. Linux machines will not generate an answer (ICMP ECHO Reply) to an ICMP ECHO request aimed at the broadcast address or at the network address.
D. Windows machines will not generate an answer (ICMP ECHO Reply) to an ICMP ECHO request aimed at the broadcast address or at the network address.
Answer: D
Explanation: As stated in the correct option, Microsoft Windows does not handle pings to a broadcast address correctly and therefore ignores them.
Q6. Data is sent over the network as clear text (unencrypted) when Basic Authentication is configured on Web Servers.
A. True
B. False
Answer: A
Explanation: Using HTTP basic authentication will result in your password being sent over the internet as clear text. Don't use this technique unless you understand what the ramifications of this are.
Q7. Ron has configured his network to provide strong perimeter security. As part of his network architecture, he has included a host that is fully exposed to attack. The system is on the public side of the demilitarized zone, unprotected by a firewall or filtering router. What would you call such a host?
A. Honeypot
B. DMZ host
C. DWZ host
D. Bastion Host
Answer: D
Explanation: A bastion host is a gateway between an inside network and an outside network. Used as a security measure, the bastion host is designed to defend against attacks aimed at the inside network. Depending on a network's complexity and configuration, a single bastion host may stand guard by itself, or be part of a larger security system with different layers of protection.
Q8. While performing ping scans into a target network you get a frantic call from the organization’s security team. They report that they are under a denial of service attack. When you stop your scan, the smurf attack event stops showing up on the organization’s IDS monitor. How can you modify your scan to prevent triggering this event in the IDS?
A. Scan more slowly.
B. Do not scan the broadcast IP.
C. Spoof the source IP address.
D. Only scan the Windows systems.
Answer: B
Explanation: Scanning the broadcast address makes the scan target all IP addresses on that subnet at the same time.
Q9. Which of the following Registry location does a Trojan add entries to make it persistent on Windows 7? (Select 2 answers)
A. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
B. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\System32\CurrentVersion\ Run
C. HKEY_CURRENT_USER\Software\Microsoft\Windows\System32\CurrentVersion\Run
D. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
Answer: AD
Q10. Gerald, the systems administrator for Hyped Enterprise, has just discovered that his network has been breached by an outside attacker. After performing routine maintenance on his servers, his discovers numerous remote tools were installed that no one claims to have knowledge of in his department.
Gerald logs onto the management console for his IDS and discovers an unknown IP address that scanned his network constantly for a week and was able to access his network through a high-level port that was not closed. Gerald traces the IP address he found in the IDS log to proxy server in Brazil.
Gerald calls the company that owns the proxy server and after searching through their logs, they trace the source to another proxy server in Switzerland. Gerald calls the company in Switzerland that owns the proxy server and after scanning through the logs again, they trace the source back to a proxy server in China.
What tool Geralds’s attacker used to cover their tracks?
A. Tor
B. ISA
C. IAS
D. Cheops
Answer: A
Explanation: Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).
