Reconnaissance Flashcards
Name Web Mirroring Tools (why do it?)
To make local to check for vulnerabilities without alerting target. Tools include: HTTrack, Black Widow, WebRipper, Teleport Pro, GNU Wget, Backstreet Browser, NCollector Studio
What does Website Watcher Do?
Checks web pages for changes and automatically notifies when there’s an update
name email tracking tools (why use?)
Email tracking tools allows an attacker to collect information such as IP addresses, mail servers, and service provider involved in sending the mail. Attackers can use this information to build a hacking strategy and to perform social engineering and other attacks.
Tools: GetNotify, ContactMonkey, Yesware, Read Notify, WhoReadMe, Trace Email, Zendio
What is a DNS resolver
also called a recursive resolver, is a server designed to receive DNS queries from web browsers and other applications. The resolver receives a hostname - for example, www.example.com - and is responsible for tracking down the IP address for that hostname. If it is cached it will just give the answer otherwise It queries the DNS hierarchy starting at root domain nameserver. it is supplied with the ip address of the authoritative top level domain NS (.com, .edu .net .org) it needs and then goes there, queries it for the authoritative dns server (anyname.com google.com etc) then from there anyname.com dns is queried where www.anyname.com is located and there is the answer.
DNS records: SRV
Service: defines the hostname and port # of servers providing specific services
dns record: SOA
Start of Authority: Identifies the primary name server for the zone. The SOA contains the hostname of the server responsible for all dns records within the namespace as well as the the basic properties of the domain.
dns record: ptr
Pointer: maps an IP to a hostname. Provide for reverse DNS. Not needed but usually associated with email servers
dns record: NS
Name Server: Define the name servers within your namespace. These servers respond to your clients’ requests for resolution
dns record: MX
Mail Exchange: Identifies email servers in your domain
dns record: CNAME
Canonical Name: provides for domain name aliases within zone. can be used to list multiple sevices (e.g. web and ftp) on the same IP. Provide alias
dns record: A
Address: Maps and IP to a hostname and is used most often for dns look ups.
dns record: 7 SOA components
Source host: Hostname of primary DNS server for the zone
Contact Email: Person responsible for zone file
Serial Number: Increments each time ZF is changed. Used by secondary server to know when to update. If SN is higher then update
Refresh Time: Amount of time a secondary server will wait to before asking for updates default is 3600 sec. 1 hour
Retry time: Amount of time secondary server will wait to retry. Default is 600 seconds
Expire time: Max time a second server will spend on zone transfer. Default is 86,400 sec (1 day)
TTL: the minimum time to live for all records in the zone if not updated by a zone transfer the records will perish. default 3600 sec (1 hour)
Commands for DNS transfer nslookup
nslookup
type “server “ (address of soa) press enter
Type “set type=any” press enter
Type ls -d nameofdomain.com
Four focuses of footprinting
Know the security posture
reduce the focus area (network range, # targets etc.)
Identify Vuln
Draw network map
Common Criteria for Information Technology Security Evaluation (4)
EAL: Evaluation Assurance level
TOE: Target Of Evaluation, What is being tested: Specific product
ST: Security Target, The documentation describing the TOE and security requirements
PP: Protection Profile, General product type
