Web server hacking
You want to carry out session hijacking on a remote server. The server and the client are communicating via TCP after a successful TCP three way handshake. The server has just received packet #155 from the client. The client has a receive window of 230 and the server has a receive window of 280. Within what range of sequence numbers should a packet, sent by the client fall in order to be accepted by the server?
B. 156-436* C. 155-435 D. 155-231
Jack is testing the perimeter security of DMC corp. He has identified a system in the demilitarized zone. Using Hping and nmap, he has verified that telnet service is running on the machine. To minimize his footprint, he spoofs his IP while attempting to telnet into the network. However, he is still unable to telnet into the network. What do you think is the reason?
The demilitarized zone is secured by a firewall
Jack cannot successfully use TCP while spoofing his IP*
Jack needs to use a tool such as nmap to telnet inside
The target system does not reply to telnet even when the service is running
An attacker tries to connect their wireless client, typically a laptop or PDA, to a basestation without authorization. What would you call this attack?
Plug-in Unauthorized Clients Attack*
Plug-in Unauthorized Renegade Base Station Attack
When SSL and SSH connections get hijacked, the only alert to the end-user is a warning that the credentials of the host and certificate have changed and ask if you trust the new ones. Your organization wants to provide some kind of interim protection its network users from such an attack. Choose the best option.
Monitor all broadcasts from the base station and renegade base station
Enable SSH's StrictHostKeyChecking option, and distribute server key signatures to mobile clients*
WEP can be typically configured in 3 possible modes. They are:
64 bit encryption, 128 bit encryption, 254 bit encryption

An attacker with the proper equipment and tools can easily flood the 2.4 GHz frequency, so that the signal to noise drops so low, that the wireless network ceases to function. What would you call this attack?
Jack supports the parasitic grid movement actively. The grid is an underground movement to deploy free wireless access zones in metropolitan areas. Jack is part of the group of volunteers deploying, at their own expense, a wireless access point on the outside of their home, or at worst at a window, with the access point connected to the volunteer's PC. What tool can an attacker use to hide his access point among legitimate access points and steal credentials?
In a switched network, the traffic flows as shown below: Step 1: Node A transmits a frame to Node C.
Step 2: The switch will examine this frame and determine what the intended host is. It will then set up a connection between Node A and Node C so that they have a 'private' connection.
Step 3: Node C will receive the frame and will examine the address. After determining that it is the intended host, it will process the frame further
Which of the following represents attacks that can help an attacker sniff on a switched network?
ARP Spoofing, Switch Hijacking, MAC corrupting
ARP Spoofing, MAC Flooding, MAC duplicating*
Switch Flooding, Switch Tampering, Switch Hijacking
MAC Spoofing, Ethernet Flooding, MAC harvesting
How would you describe a simple yet very effective mechanism for sending and receiving unauthorized information or data between machines without alerting any firewalls and IDS's on a network?
Derek transmits an ARP to a non-broadcast address. He gets a response from a machine on the network of its IP address. What must Derek infer?
The machine has been trojaned by an attacker
The machine is running a sniffer in promiscuous mode*
The machine is configured with a local address loop
His system has its ARP cached and is looping back into the network
During the scanning portion of his penetration test, Ed discovered a handful of Oracle servers. Later, Ed found that those Oracle servers were being used by the web servers to retrieve information. Ed decided that he should try some SQL injection attacks in order to read information out of the Oracle servers. He opens the web page in his browser and begins injecting commands. After hours of attempts, Ed is having no luck getting even a small amount of information out of the databases. What is the probable cause of this? (Select the Best Answer)
You cannot do SQL injection against Oracle database
You must directly connect to the database instead of using the web server
You cannot use a web browser to perform SQL injection
Ed is not using SQL Plus to inject commands
As inferred from the following entry which of the following statements describes the attacker's effort? cmd/c C: \ProgramFiles\CommonFiles\system\...\pdump.exe>>C:\mine.txt
Enumerate users and passwords with Password Dump
Copy pdump.exe and rename it to mine.txt
Execute pdump.exe and save into mine.txt*
Copy mine.txt into the directory where pdump.exe resides
John has a proxy server on his network which caches and filters web access. He has shut down all unnecessary ports and services. Additionally, he has installed a firewall (Cisco PIX) that will not allow users to connect to any outbound ports. Jack, a network user has successfully connected to a remote server on port 80 using netcat. He could in turn drop a shell from the remote machine. John wants to harden his network such that a remote user does not do the same to his network. Choose the option that can be easily and more effectively implemented.
Do not use a proxy as application layer does not provide adequate protection
Limit HTTP CONNECT on the network*
Sniff the traffic and look for lengthy connection periods
Filter port 80
Reflective DDoS attacks do not send traffic directly at the targeted host. Instead, they usually spoof the originating IP addresses and send the requests at the reflectors. These reflectors
(usually routers or high- powered servers with a large amount of network resources at their disposal) then reply to the spoofed targeted traffic by sending loads and loads of data to the final target. How would you detect these reflectors on your network?
Run Vulnerability scanner on your network to detect these reflectors
Run floodnet tool to detect these reflectors
Look for the banner text by running Zobbie Zappers tools
Scan the network using Nmap for the services used by these reflectors
You are programming a buffer overflow exploit and you want to create a NOP sled of 200 bytes in the program exploit.c

A. It uses a TCP Timestamp packet a good way to elicit a time exceed in transit message.B. It uses a protocol that can be rejected at the gateways on its technique to its vacation spot.C. It manipulates the cost of time to are living (TTL) parameter packet to elicit a time handed in transit message.D. It manipulated flags within packets to drive gateways into producing error messages.
answer: CExplanation: Traceroute works with the aid of increasing the "time-to-live" cost of every successive batch of packets sent. the first three packets have a time-to-are living (TTL) cost of one (implying that they make a single hop). The next three packets have a TTL value of 2, and so forth. When a packet passes via a number, invariably the host decrements the TTL price by means of one, and forwards the packet to the next host. When a packet with a TTL of one reaches a bunch, the host discards the packet and sends an ICMP time surpassed (type 11) packet to the sender. The traceroute utility uses these returning packets to supply an inventory of hosts that the packets have traversed en route to the destination.giggle has been used to capture packets on the community. On learning the packets, the penetration tester finds it to be abnormal. in case you have been the penetration tester, why would you discover this abnormal?
(word: The student is being validated on idea learnt all the way through passive OS fingerprinting, primary TCP/IP connection ideas and the capacity to study 312-50 packet signatures from a sniff dumo.)

what's abnormal about this assault? (choose the most appropriate remark)
A. here is now not a spoofed packet as the IP stack has increasing numbers for the three flags.B. this is returned orifice exercise because the scan comes from port 31337.C. The attacker desires to keep away from creating a sub-carrier connection that is not always legitimate.D. There packets had been created by a tool; they had been now not created via a typical IP stack.
