You are footprinting an organization and gathering competitive intelligence. You visit the company's website for contact information and telephone numbers but do not find them listed there. You know they had the entire staff directory listed on their website 12 months ago but now it is not there. Is there any way you can retrieve information from a website that is outdated?
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?
Nathan is testing some of his network devices. Nathan is using Macof to try and flood the ARP cache of these switches. If these switches' ARP cache is successfully flooded, what will be the result?
What sequence of packets is sent during the initial TCP three-way handshake?
Blane is a network security analyst for his company. From an outside IP, Blane performs an XMAS scan using Nmap. Almost every port scanned does not illicit a response. What can he infer from this kind of response?
"Testing the network using the same methodologies and tools employed by attackers" Identify the correct terminology that defines the above statement.
Which definition below best describes a covert channel?
The programmers on your team are analyzing the free, open source software being used to run FTP services on a server in your organization. They notice that there is excessive number of functions in the source code that might lead to buffer overflow. These C++ functions do not check bounds. Identify the line in the source code that might lead to buffer overflow?
William has received a Chess game from someone in his computer programming class through email. William does not really know the person who sent the game very well, but decides to install the game anyway because he really likes Chess.
After William installs the game, he plays it for a couple of hours. The next day, William plays the Chess game again and notices that his machine has begun to slow down. He brings up his Task Manager and sees the following programs running:
What has William just installed?
You went to great lengths to install all the necessary technologies to prevent hacking attacks, such as expensive firewalls, antivirus software, anti-spam systems and intrusion detection/prevention tools in your company's network. You have configured the most secure policies and tightened every device on your network. You are confident that hackers will never be able to gain access to your network with complex security system in place. Your peer, Peter Smith who works at the same department disagrees with you. He says even the best network security technologies cannot prevent hackers gaining access to the network because of presence of "weakest link" in the security chain. What is Peter Smith talking about?
What framework architecture is shown in this exhibit?
Leesa is the senior security analyst for a publicly traded company. The IT department recently rolled out an intranet for company use only with information ranging from training, to holiday schedules, to human resources data. Leesa wants to make sure the site is not accessible from outside and she also wants to ensure the site is Sarbanes-Oxley (SOX) compliant. Leesa goes to a public library as she wants to do some Google searching to verify whether the company's intranet is accessible from outside and has been indexed by Google. Leesa wants to search for a website title of "intranet" with part of the URL containing the word "intranet" and the words "human resources" somewhere in the webpage.
What Google search will accomplish this?
John is using a special tool on his Linux platform that has a database containing signatures to be able to detect hundreds of vulnerabilities in UNIX, Windows, and commonly used web CGI/ASPX scripts. Moreover, the database detects DDoS zombies and Trojans as well. What would be the name of this tool?
Johnny is a member of the hacking group Orpheus1. He is currently working on breaking into the Department of Defense's front end Exchange Server. He was able to get into the server, located in a DMZ, by using an unused service account that had a very weak password that he was able to guess. Johnny wants to crack the administrator password, but does not have a lot of time to crack it. He wants to use a tool that already has the LM hashes computed for all possible permutations of the administrator password.
What tool would be best used to accomplish this?
This method is used to determine the Operating system and version running on a remote target system. What is it called?
In which location, SAM hash passwords are stored in Windows 7?
TCP packets transmitted in either direction after the initial three-way handshake will have which of the following bit set?
A simple compiler technique used by programmers is to add a terminator 'canary word' containing four letters NULL (0x00), CR (0x0d), LF (0x0a) and EOF (0xff) so that most string operations are terminated. If the canary word has been altered when the function returns, and the program responds by emitting an intruder alert into syslog, and then halts what does it indicate?
In which step Steganography fits in CEH System Hacking Cycle (SHC)
You establish a new Web browser connection to Google. Since a 3-way handshake is required for any TCP connection, the following actions will take place.
DNS query is sent to the DNS server to resolve www.google.com
DNS server replies with the IP address for Google?
SYN packet is sent to Google.
Google sends back a SYN/ACK packet
Your computer completes the handshake by sending an ACK
The connection is established and the transfer of data commences
Which of the following packets represent completion of the 3-way handshake?
