Which of the following statement correctly defines ICMP Flood Attack? (Select 2 answers)
Annie has just succeeded in stealing a secure cookie via a XSS attack. She is able to replay the cookie even while the session is invalid on the server. Why do you think this is possible?
Consider the following code:
URL:http://www.certified.com/search.pl?
text=
If an attacker can trick a victim user to click a link like this, and the Web application does not validate input, then the victim's browser will pop up an alert showing the users current set of cookies. An attacker can do much more damage, including stealing passwords, resetting your home page, or redirecting the user to another Web site.
What is the countermeasure against XSS scripting?
Which type of hacker represents the highest risk to your network?
SNMP is a connectionless protocol that uses UDP instead of TCP packets (True or False)
This tool is widely used for ARP Poisoning attack. Name the tool.
Peter extracts the SID list from Windows 2008 Server machine using the hacking tool "SIDExtracter". Here is the output of the SIDs:
From the above list identify the user account with System Administrator privileges?
Attacking well-known system defaults is one of the most common hacker attacks. Most software is shipped with a default configuration that makes it easy to install and setup the application. You should change the default settings to secure the system.
Which of the following is NOT an example of default installation?
Samuel is the network administrator of DataX Communications, Inc. He is trying to configure his firewall to block password brute force attempts on his network. He enables blocking the intruder's IP address for a period of 24 hours' time after more than three unsuccessful attempts. He is confident that this rule will secure his network from hackers on the Internet.
But he still receives hundreds of thousands brute-force attempts generated from various IP addresses around the world. After some investigation he realizes that the intruders are using a proxy somewhere else on the Internet which has been scripted to enable the random usage of various proxies on each request so as not to get caught by the firewall rule.
Later he adds another rule to his firewall and enables small sleep on the password attempt so that if the password is incorrect, it would take 45 seconds to return to the user to begin another attempt. Since an intruder may use multiple machines to brute force the password, he also throttles the number of connections that will be prepared to accept from a particular IP address. This action will slow the intruder's attempts.
Samuel wants to completely block hackers brute force attempts on his network.
What are the alternatives to defending against possible brute-force password attacks on his site?
In which part of OSI layer, ARP Poisoning occurs?
In the context of password security: a simple dictionary attack involves loading a dictionary file (a text file full of dictionary words) into a cracking application such as L0phtCrack or John the Ripper, and running it against user accounts located by the application. The larger the word and word fragment selection, the more effective the dictionary attack is. The brute force method is the most inclusive - though slow. Usually, it tries every possible letter and number combination in its automated exploration. If you would use both brute force and dictionary combined together to have variations of words, what would you call such an attack?
Steven the hacker realizes the network administrator of Acme Corporation is using syskey in Windows 2008 Server to protect his resources in the organization. Syskey independently encrypts the hashes so that physical access to the server, tapes, or ERDs is only first step to cracking the passwords. Steven must break through the encryption used by syskey before he can attempt to use brute force dictionary attacks on the hashes. Steven runs a program called "SysCracker" targeting the Windows 2008 Server machine in attempting to crack the hash used by Syskey. He needs to configure the encryption level before he can launch the attack. How many bits does Syskey use for encryption?
BankerFox is a Trojan that is designed to steal users' banking data related to certain banking entities.
When they access any website of the affected banks through the vulnerable Firefox 3.5 browser, the Trojan is activated and logs the information entered by the user. All the information entered in that website will be logged by the Trojan and transmitted to the attacker's machine using covert channel.
BankerFox does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer.
What is the most efficient way an attacker located in remote location to infect this banking Trojan on a victim's machine?

You just purchased the latest DELL computer, which comes pre-installed with Windows 7, McAfee antivirus software and a host of other applications. You want to connect Ethernet wire to your cable modem and start using the computer immediately. Windows is dangerously insecure when unpacked from the box, and there are a few things that you must do before you use it.
This attack technique is used when a Web application is vulnerable to an SQL Injection but the results of the Injection are not visible to the attacker.
How many bits encryption does SHA-1 use?
Ursula is a college student at a University in Amsterdam. Ursula originally went to college to study engineering but later changed to marine biology after spending a month at sea with her friends. These friends frequently go out to sea to follow and harass fishing fleets that illegally fish in foreign waters. Ursula eventually wants to put companies practicing illegal fishing out of business. Ursula decides to hack into the parent company's computers and destroy critical data knowing fully well that, if caught, she probably would be sent to jail for a very long time. What would Ursula be considered?
