How to Investigate and Solve Cybercrime
1 DomainTools Cybercrime Investigation Connecting the Dots of Online DNA DOMAINTOOLS SOLUTION BRIEF WWW.DOMAINTOOLS.COM WWW.DOMAINTOOLS.COM 2 INTRODUCTION UNDERSTANDING THE DNA OF DNS DATA As anyone who has watched modern crime television knows, DNA of some form is often left behind at the scene of a crime. Similarly, when a cybercrime is perpetrated it is not unusual that traces of evidence are left behind in the form of Domain Name System (DNS) and Whois data. Cybercrime costs businesses billions every year. A 2012 Ponemon study found that cyber crime cost businesses on average $8.9 million each year (based on a study of 56 organizations), with a range of $1.4 million to $46 million. And attacks are becoming more frequent—The same study found that attacks were up 42% from the previous year. Whether it’s cybersquatting, the theft of valuable intellectual property, financial account hacking or the sale of counterfeit goods on a fraudulent domain, cybercriminals continue to grow more brazen and sophisticated in their tactics. To effectively combat this costly criminal behavior, cyber investigators must employ a range of new tools and techniques to quickly and proactively identify attackers. RESPONSE AND INVESTIGATION Whether you are attacked via a DDOS, phishing, malware or Advanced Persistent Threat tactics, one thing is consistent: in every case, there is a communication protocol applied. That is, all types of cyber attack involve sending information from one node on the Internet to another. DomainTools can help map these nodes and their connections, thereby providing investigators and response teams with the necessary information to stop further attacks and identify perpetrators. -

Internic Faqs on the Domain Names, Registrars, and Registration
InterNIC I FAQs on the Domain Names, Registrars, and Registration 12/4/11 1:20 PM InterNlC Home ~Re istrsrs FAQ Whois InterNIC FAQs on the Domain Names, Registrars, and Registration The following is a list of frequently asked questions (FAQs) about the domain name registration process and the new competitive registration environment. It is expected that this list will be updated frequently, so please check back often. What is the domain name system? The Domain Name System (DNS) helps users to find their way around the Internet. Every computer on the Internet has a unique address — just like a telephone number — which is a rather complicated string of numbers. It is called its "IP address" (IP stands for "Internet Protocol" ). IP Addresses are hard to remember. The DNS makes using the Internet easier by allowing a familiar string of letters (the "domain name") to be used instead of the arcane IP address. So instead of typing 207.151.159.3, you can type www.internic.net. It is a "mnemonic" device that makes addresses easier to remember. What does it mean to "register" a domain name? When you register a domain name, you are inserting an entry into a directory of all the domain names and their corresponding computers on the Internet. How do I register a domain name? Domain names ending with .aero, .biz, .corn, .coop, .info, .museum, .name, .net, .org, or .pro can be registered through many different companies (known as "registrars") that compete with one another. A listing of these companies appears in the Re istrar Directo on this site. -

Domain Name System 1 Domain Name System
Domain Name System 1 Domain Name System The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. A Domain Name Service translates queries for domain names (which are easier to understand and utilize when accessing the internet) into IP addresses for the purpose of locating computer services and devices worldwide. An often-used analogy to explain the Domain Name System is that it serves as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses. For example, the domain name www.example.com translates to the addresses 192.0.43.10 (IPv4) and 2620:0:2d0:200::10 (IPv6). The Domain Name System makes it possible to assign domain names to groups of Internet resources and users in a meaningful way, independent of each entity's physical location. Because of this, World Wide Web (WWW) hyperlinks and Internet contact information can remain consistent and constant even if the current Internet routing arrangements change or the participant uses a mobile device. Internet domain names are easier to remember than IP addresses such as 208.77.188.166 (IPv4) or 2001:db8:1f70::999:de8:7648:6e8 (IPv6). Users take advantage of this when they recite meaningful Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer actually locates them. The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. -

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. -
An Introduction to Socket Programming
An Introduction to Socket Programming (by) Reg Quinton <[email protected]> © $Id: socket.html,v 1.8 1997/05/02 20:17:16 reggers Exp $ Contents: Introduction BEWARE Existing Services Netstat Observations Host names and IP numbers Programming Calls Services and Ports Programming Calls Socket Addressing File Descriptors and Sockets File Descriptors Sockets Client Connect Client Communication Stdio Buffers Server Applications Server Bind Listen and Accept Inetd Services Inetd Comments Whois Daemon Running the Daemon The Code Connecting to the Server Whois Client Perl Socket Programming Final Comments Note Well Suggested Reading Author Introduction: These course notes are directed at Unix application programmers who want to develop client/server applications in the TCP/IP domain (with some hints for those who want to write UDP/IP applications). Since the Berkeley socket interface has become something of a standard these notes will apply to programmers on other platforms. Fundamental concepts are covered including network addressing, well known services, sockets and ports. Sample applications are examined with a view to developing similar applications that serve other contexts. Our goals are to develop a function, tcpopen(server,service), to connect to service. to develop a server that we can connect to. This course requires an understanding of the C programming language and an appreciation of the programming environment (ie. compilers, loaders, libraries, Makefiles and the RCS revision control system). If you want to know about socket programming with perl(1) then see below but you should read everything first. Our example is the UWO/ITS whois(1) service -- client and server sources available in: Network Services: http://www.uwo.ca/its/ftp/pub/unix/network Look for the whois(1) client and the whoisd(8) server. -
