    Jason works in the sales and marketing department for a very large advertising agency located in Atlanta.  Jason is working on a very important marketing campaign for his company's largest client. Before the project could be completed and implemented, a competing advertising company comes out with the exact same marketing materials and advertising, thus rendering all the work done for Jason's client unusable. Jason is questioned about this and says he has no idea how all the material ended up in the hands of a competitor.   Without any proof, Jason's company cannot do anything except move on. After working on another high profile client for about a month, all the marketing and sales material again ends up in the hands of another competitor and is released to the public before Jason's company can finish the project. Once again, Jason says that he had nothing to do with it and does not know how this could have happened. Jason is given leave with pay until they can figure out what is going on.   Jason's supervisor decides to go through his email and finds a number of emails that were sent to the competitors that ended up with the marketing material. The only items in the emails were attached jpg files, but nothing else. Jason's supervisor opens the picture files, but cannot find anything out of the ordinary with them.

    TCP SYN Flood attack uses the three-way handshake mechanism. 1. An attacker at system A sends a SYN packet to victim at system B. 2. System B sends a SYN/ACK packet to victim A. 3. As a normal three-way handshake mechanism system A should send an ACK packet to system B, however, system A does not send an ACK packet to system B. In this case client B is waiting for an ACK packet from client A.   This status of client B is called _________________

    Lori is a Certified Ethical Hacker as well as a Certified Hacking Forensics Investigator working as an IT security consultant. Lori has been hired on by Kiley Innovators, a large marketing firm that recently underwent a string of thefts and corporate espionage incidents. Lori is told that a rival marketing company came out with an exact duplicate product right before Kiley Innovators was about to release it. The executive team believes that an employee is leaking information to the rival company. Lori questions all employees, reviews server logs, and firewall logs; after which she finds nothing. Lori is then given permission to search through the corporate email system. She searches by email being sent to and sent from the rival marketing company.   She finds one employee that appears to be sending very large email to this other marketing company, even though they should have no reason to be communicating with them. Lori tracks down the actual emails sent and upon opening them, only finds picture files attached to them. These files seem perfectly harmless, usually containing some kind of joke. Lori decides to use some special software to further examine the pictures and finds that each one had hidden text that was stored in each picture.   What technique was used by the Kiley Innovators employee to send information to the rival marketing company?

    • The Kiley Innovators employee used cryptography to hide the information in the emails sent

    • The method used by the employee to hide the information was logical watermarking

    An attacker finds a web page for a target organization that supplies contact information for the company. Using available details to make the message seem authentic, the attacker drafts e-mail to an employee on the contact page that appears to come from an individual who might reasonably request confidential information, such as a network administrator.   The email asks the employee to log into a bogus page that requests the employee's user name and password or click on a link that will download spyware or other malicious programming.   Google's Gmail was hacked using this technique and attackers stole source code and sensitive data from Google servers. This is highly sophisticated attack using zero-day exploit vectors, social engineering and malware websites that focused on targeted individuals working for the company.   What is this deadly attack called? - ProProfs

    Bret is a web application administrator and has just read that there are a number of surprisingly common web application vulnerabilities that can be exploited by unsophisticated attackers with easily available tools on the Internet. He has also read that when an organization deploys a web application, they invite the world to send HTTP requests. Attacks buried in these requests sail past firewalls, filters, platform hardening, SSL, and IDS without notice because they are inside legal HTTP requests. Bret is determined to weed out vulnerabilities.   What are some of the common vulnerabilities in web applications that he should be concerned about?

    • Non-validated parameters, broken access control, broken account and session management, cross-site scripting and buffer overflows are just a few commonvulnerabilities

    • Visible clear text passwords, anonymous user account set as default, missing latest security patch, no firewall filters set and no SSL configured are just a few common vulnerabilities

    • No SSL configured, anonymous user account set as default, missing latest security patch, no firewall filters set and an inattentive system administrator are just a few common vulnerabilities

    • No IDS configured, anonymous user account set as default, missing latest security patch, no firewall filters setand visible clear text passwords are just a few common vulnerabilities

    Correct Answer
    A. Non-validated parameters, broken access control, broken account and session management, cross-site scripting and buffer overflows are just a few commonvulnerabilities

    The following script shows a simple SQL injection. The script builds an SQL query by concatenating hard-coded strings together with a string entered by the user: The user is prompted to enter the name of a city on a Web form. If she enters Chicago, the query assembled by the script looks similar to the following:   SELECT * FROM OrdersTable WHERE ShipCity = 'Chicago'   How will you delete the OrdersTable from the database using SQL Injection? - ProProfs

    Cyber Criminals have long employed the tactic of masking their true identity. In IP spoofing, an attacker gains unauthorized access to a computer or a network by making it appear that a malicious message has come from a trusted machine, by "spoofing" the IP address of that machine.   How would you detect IP spoofing?

    • Check the IPID of the spoofed packet and compare it with TLC checksum. If the numbers match then it is spoofed packet

    • Probe a SYN Scan on the claimed host and look for a response SYN/FIN packet, if the connection completes then it is a spoofed packet

    • Turn on 'Enable Spoofed IP Detection' in Wireshark, you will see a flag tick if the packet is spoofed

    • Sending a packet to the claimed host will result in a reply. If the TTL in the reply is not the same as the packet being checked then it is a spoofed packet

    Correct Answer
    A. Sending a packet to the claimed host will result in a reply. If the TTL in the reply is not the same as the packet being checked then it is a spoofed packet

    • If (I

    • If (I >= 200) then exit (1)
