Which of the following is an attack in which a secret value like a hash is captured and then reused at a later time to gain access to a system without ever decrypting or decoding the hash.

Travis works primarily from home as a medical transcriptions.

He just bought a brand new Dual Core Pentium Computer with over 3 GB of RAM. He uses voice recognition software is processor intensive, which is why he bought the new computer. Travis frequently has to get on the Internet to do research on what he is working on. After about two months of working on his new computer, he notices that it is not running nearly as fast as it used to.

Travis uses antivirus software, anti-spyware software and always keeps the computer up- to-date with Microsoft patches.

After another month of working on the computer, Travis computer is even more noticeable slow. Every once in awhile, Travis also notices a window or two pop-up on his screen, but they quickly disappear. He has seen these windows show up, even when he has not been on the Internet. Travis is really worried about his computer because he spent a lot of money on it and he depends on it to work. Travis scans his through Windows Explorer and check out the file system, folder by folder to see if there is anything he can find. He spends over four hours pouring over the files and folders and can’t find anything but before he gives up, he notices that his computer only has about 10 GB of free space available. Since has drive is a 200 GB hard drive, Travis thinks this is very odd.

Travis downloads Space Monger and adds up the sizes for all the folders and files on his computer. According to his calculations, he should have around 150 GB of free space.
What is mostly likely the cause of Travi’s problems?

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 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 use.

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?

_____ is found in all versions of NTFS and is described as the ability to fork file data into existing files without affecting their functionality, size, or display to traditional file browsing utilities like dir or Windows Explorer

Bob is acknowledged as a hacker of repute and is popular among visitors of "underground" sites. Bob is willing to share his knowledge with those who are willing to learn, and many have expressed their interest in learning from him. However, this knowledge has a risk associated with it, as it can be used for malevolent attacks as well.

In this context, what would be the most affective method to bridge the knowledge gap between the "black" hats or crackers and the "white" hats or computer security professionals? (Choose the test answer)

Jess the hacker runs L0phtCrack’s built-in sniffer utility which grabs SMB password hashes and stores them for offline cracking. Once cracked, these passwords can provide easy access to whatever network resources the user account has access to.

But Jess is not picking up hashed from the network.

Why?

John is a keen administrator, and has followed all of the best practices as he could find on securing his Windows Server.

How is it possible for a remote attacker to decipher the name of the administrator account if it has been renamed?
