Dan is conducting a penetration testing and has found a vulnerability in a Web Application which gave him the sessionID token via a cross site scripting vulnerability. Dan wants to replay this token. However, the session ID manager (on the server) checks the originating IP address as well. Dan decides to spoof his IP address in order to replay the sessionID. Why do you think Dan might not be able to get an interactive session?
Answer(s): B
Spoofing your IP address is only effective when there is no need to establish a two way connection as all traffic meant to go to the attacker will end up at the place of the spoofed address.
When discussing passwords, what is considered a brute force attack?
Answer(s): A
Brute force cracking is a time consuming process where you try every possible combination of letters, numbers, and characters until you discover a match.
You are sniffing as unprotected WiFi network located in a JonDonalds Cybercafe with Ethereal to capture hotmail e-mail traffic. You see lots of people using their laptops browsing the web while snipping brewed coffee from JonDonalds. You want to sniff their email message traversing the unprotected WiFi network.Which of the following ethereal filters will you configure to display only the packets with the hotmail messages?
Each Hotmail message contains the tag Reply-To:<sender address> and “xxxx-xxx-xxx.xxxx.hotmail.com” in the received tag.
William has received a Tetris 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 Tetris.After William installs the game, he plays it for a couple of hours. The next day, William plays the Tetris game again and notices that his machines have begun to slow down. He brings up his Task Manager and sees the following programs running (see Screenshot):What has William just installed?
RATs are malicious programs that run invisibly on host PCs and permit an intruder remote access and control. On a basic level, many RATs mimic the functionality of legitimate remote control programs such as Symantec's pcAnywhere but are designed specifically for stealth installation and operation. Intruders usually hide these Trojan horses in games and other small programs that unsuspecting users then execute on their PCs. Typically, exploited users either download and execute the malicious programs or are tricked into clicking rogue email attachments.
Matthew re-injects a captured wireless packet back onto the network. He does this hundreds of times within a second. The packet is correctly encrypted and Matthew assumes it is an ARP request packet. The wireless host responds with a stream of responses, all individually encrypted with different IVs. What is this attack most appropriately called?
A replay attack is a form of network attack in which a valid data transmission is maliciously or fraudulently repeated or delayed. This is carried out either by the originator or by an adversary who intercepts the data and retransmits it, possibly as part of a masquerade attack by IP packet substitution (such as stream cipher attack).
