Definition: Sniffing
Sniffing is a data interception technology Sniffer is a program or device that captures p g p the vital information from the network traffic specific to a particular network The objective of sniffing is to steal: • Passwords (from email, the web, SMB, ftp, SQL, or telnet) • Email text • Files in transfer (email files, ftp files, or SMB) Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
6.
Protocols Vulnerable to
Sniffing Protocols that are susceptible to sniffers i l d iff include: • Telnet and Rlogin: Keystrokes including user names and passwords • HTTP: Data sent in the clear text • SMTP: Passwords and data sent in clear text • NNTP: Passwords and data sent in clear text • POP: Passwords and data sent in clear text • FTP: Passwords and data sent in clear text • IMAP: Passwords and data sent in clear text Copyright © by EC-Council EC-Council All Rights Reserved.

Types of Sniffing
There are two types of sniffing Passive sniffing Active sniffing Sniffing through a iffi h h Sniffing through a iffi h h Hub Switch Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
8.
Passive Sniffing
Attacker HUB It is called passive because it is difficult to p detect “Passive sniffing” means sniffing through a hub Passive sniffing An attacker simply connects the laptop to the LAN hub d h b and starts sniffing iffi Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
9.
Active Sniffing
Switch Attacker Switch looks at MAC address associated with each frame, sending data only to the connected port An attacker tries to poison switch by sending bogus MAC addresses Sniffing through a switch Difficult to sniff Can easily be detected Techniques for active sniffing: • MAC flooding • ARP spoofing LAN Copyright © by EC-Council EC-Council All Rights Reserved.

Wiretap
Wiretapping is the monitoring of telephone and Internet conversations by a third party The monitoring connection was applied to the wires of the telephone line being monitored and a small amount of the electrical signal carrying th conversation get t l t i l i l i the ti t tapped d Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
39.
RF Transmitter Wiretaps
In radio frequency (RF) transmitter tap technique, a small RF transmitter is attached to the telephone li or within the i i h d h l h line i hi h telephone instrument In these wiretaps, a dio fl ct ations from the telephone iretaps audio fluctuations conversation modulate the transmitter carrier that transmit the conversation into free air space Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
40.
Infinity Transmitter
An infinity transmitter is the device used as a wiretap to monitor th communication it the i ti It operates independent of the telephone instrument and requires its own telephone li i i l h line It can be called from a remote telephone and activated with a tone signal i l Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
41.
Slave Parallel Wiretaps
Slave Parallel Wiretaps device works in the same way as infinity transmitter and combines these f t t itt d bi th features with a parallel wiretap ith ll l i t The slave is connected anywhere with the target telephone line In these wiretaps, an attacker needs a working telephone line located in p g p the same cable, cross-connect, or closet as the target line Once lines are connected to the slave, the eavesdropper can call his , pp leased telephone line and activate the slave After activation, the slave automatically connects the eavesdroppers telephone line to the target telephone line Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited

Switched Port Analyzer
(SPAN) The Switched Port Analyzer (SPAN) feature, also called port mirroring or port monitoring, monitoring selects network traffic for analysis by a network analyzer The network analyzer can be a Cisco SwitchProbe device or other Remote Monitoring (RMON) probe SPAN feature applies on switches because of a fundamental difference that switches have with hubs In a single local SPAN session, you can monitor source port traffic such as received (Rx), transmitted (Tx), or bidirectional (both) traffic Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
43.
SPAN Port
SPAN port is the port to which sniffer is attached and configured to receive a copy of every packets sent from the source host to the destination host • Source (SPAN) port: A port that is monitored with the use of the SPAN feature • Destination (SPAN) port: A port that monitors source ports, usually where a network analyzer is connected Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
44.
Lawful Intercept
Lawful intercept is a process that enables a Law Enforcement Agency (LEA) to perform electronic surveillance on an individual (a target) as authorized by a judicial or administrative order The surveillance is performed through the use of wiretaps on traditional telecommunications and Internet services in voice, data and multiservice voice data, networks The LEA delivers a request for a wiretap to the target's service p q p g provider, who is , responsible for intercepting data communication to and from the individual The service provider uses the target's IP address or session to determine which target s of its edge routers handles the target's traffic (data communication) The service provider then intercepts the target's traffic as it passes through the router and sends a copy of the i d d f h intercepted traffic to the LEA without the target's d ffi h ih h ' knowledge. Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
45.
Benefits of Lawful
Intercept Allows multiple LEAs to run a lawful intercept on the same target without each other s other's knowledge Does not affect subscriber services on the router Supports wiretaps in both the input and output direction Supports wiretaps of individual subscribers that share a single physical interface i f Neither the network administrator nor the calling parties is aware that packets are being copied or that the call is being tapped Hides information about lawful intercepts from all but the most privileged users Provides two secure interfaces for performing an intercept: one for setting up the wiretap and one for sending the intercepted traffic to the LEA Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
46.
Network Components Used
for Lawful Intercept Mediation Device: • A mediation device (supplied by a third-party vendor) handles most of the processing for the lawful intercept Intercept Access Point: • An intercept access point ( (IAP) is a device that provides ) d h d information for the lawful intercept Collection Function: • The collection function is a program that stores and processes traffic intercepted by the service provider Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
47.
ARP Spoofing Attack
ARP resolves IP addresses to MAC (hardware) ( ) address of interface to send data ARP packets can be forged to send data to the attacker’s machine An attacker can exploit ARP poisoning to intercept the network traffic between two machines on the network By MAC flooding a switch's ARP table with spoofed ARP replies, the attacker can overload switches and then packet sniff network while switch is in “forwarding mode” Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
48.
How Does ARP
Spoofing Work When a legitimate user initiates a g session with another user in the same Layer 2 broadcast domain, an ARP request is broadcasted using the recipient's IP address and the recipient s sender waits for the recipient to respond with a MAC address Malicious user eavesdrops on this unprotected Layer 2 broadcast domain and can respond to a broadcast ARP request and reply to b d d l the sender by spoofing the intended recipient's MAC address Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
49.
ARP Poisoning
Hey 10.1.1.1 are you there? Step 2: Another legitimate user responds to the ARP request Step 1: Legitimate user sends ARP request, which the Switch broadcasts onto the wire Yes I am here. This is I' here 10.1.1.1 and my MAC address is 1:2:3:4:5:6 No, I' am 10.1.1.1 and my Switch MAC address is 9:8:7:6:5:4 Legitimate User Step 3: Malicious user Step 4: Information for IP eavesdrops on the ARP request address 10.1.1.1 is now being and responds after the sent to MAC address 9:8:7:6:5:4 legitimate user spoofs the legitimate l iti t response and sends d d his malicious MAC address to Internet the originator of the request Attacker Copyright © by EC-Council EC-Council All Rights Reserved.

DNS Poisoning Techniques
The substitution of a false Internet provider address at the domain name service level (e.g., where web addresses are converted into (e g numeric Internet provider addresses) DNS poisoning is a technique that tricks a DNS server into believing i i i h i h i k i b li i that it has received authentic information when, in reality, it has not Types of DNS Poisoning: Intranet DNS Spoofing (Local network) Internet DNS Spoofing (Remote network) Proxy Server DNS Poisoning DNS Cache Poisoning Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
89.
1. Intranet DNS
Spoofing (Local Network) For this technique, you must be connected to the local area network (LAN) and be able to sniff packets It works well against switches with ARP poisoning the router What is the IP address of www.xsecurity.com it Router Real Website 1 IP 10.0.0.254 www.xsecurity.com IP: 200.0.0.45 DNS Request 3 Hacker poisons Hacker’s fake website sniffs the the router and credential and redirects the request to 2 4 all the router real website traffic is forwarded to his machine Rebecca types Hacker sets up fake www.xsecurity.com in her y Website Web Browser www.xsecurity.com IP: 10.0.0.3 IP: 10.0.0.5 Hacker runs arpspoof/dnsspoof f/d f www.xsecurity.com Copyright © by EC-Council EC-Council All Rights Reserved.

2. Internet DNS
Spoofing (Remote Network) Internet DNS Spoofing sends a Trojan to Rebecca’s machine and changes her DNS IP address to that of the attacker’s It works across networks and is easy to set up and implement Real Website www.xsecurity.com IP: 200.0.0.45 2 4 Hacker’s fake website sniffs the credential and redirects the request to real website 5 Rebecca types 3 1 www.xsecurity.com in her W b B h Web Browser Hacker’s infects Rebecca’s computer by changing her DNS IP address to: 200.0.0.2 Fake Website IP: 65.0.0.2 Hacker runs DNS Server in Russia IP: 200.0.0.2 Copyright © by EC-Council EC-Council All Rights Reserved. Reproduction is Strictly Prohibited
91.
Internet DNS Spoofing
To redirect all DNS request traffic going from the host machine to come to you 1. Set up a fake website on your computer 2. Install treewalk and modify the file mentioned in readme.txt to your IP address; Treewalk will make you the DNS server 3. Modify file dns-spoofing.bat and replace the IP address with your IP address 4. Trojanize the dns-spoofing.bat file and send it to Jessica (ex: chess.exe) 5. When host clicks trojaned file, it will replace Jessica’s DNS entry in her TCP/IP properties with that of your machine’s 6. You will become the DNS server for Jessica and her DNS requests will go through you 7. When Jessica connects to XSECURITY.com, she resolves to fake XSECURITY website; you sniff the password and send her to the real website Copyright © by EC-Council EC-Council All Rights Reserved.

4. DNS Cache
Poisoning To T perform a cache poisoning attack, th attacker exploits a fl i f h i i tt k the tt k l it flaw in the DNS server software that can make it accept incorrect information If the server does not correctly validate DNS responses to ensure that they have come from an authoritative source, the server will end up caching the incorrect entries locally and serve them to users that make the same request • For example, an attacker poisons the IP address DNS entries for a target example website on a given DNS server, replacing them with the IP address of a server he/she controls • He then creates fake entries for files on the server he/she controls with names matching those on the target server hi h h Copyright © by EC-Council EC-Council All Rights Reserved.
