What Do Hackers Do

Today, mainstream usage of “hacker” mostly refers to computer criminals, due to the mass media usage of the word since the 1980s. This includes what hacker slang calls “script kiddies,” people breaking into computers using programs written by others, with very little knowledge about the way they work.

What Do Hackers Do

Truly talented hackers know a great deal about the following:

  1. Programming languages, such as C, C++, Java, Perl, JavaScript, and VBScript.
  2. How operating systems work. A serious security professional or hacker understands not only how to click the right spot on an interface, but also understands what happens under the hood when that interface is clicked.
  3. The history of local-area-network (LAN)- and Internet-based services, such as the Network File System (NFS), Web servers, Server Message Block (SMB, which is what allows Microsoft systems to share file and printing services), and of course e-mail servers.
  4. Many hackers attack the protocols used in networks. The Internet uses Transmission Control Protocol/Internet Protocol (TCP/IP), which is a fast, efficient, and powerful transport and addressing method. This protocol is in fact an entire suite of protocols. Some of these include Telnet, DNS, the File Transfer Protocol (FTP), and all protocols associated with e-mail servers, which include the Simple Mail Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), and the Internet Messaging Application Protocol (IMAP).
  5. How applications interact with each other. Today’s operating systems contain components that allow applications to “talk” to each other efficiently. For example, using Microsoft’s Component Object Model (COM) and other technologies, one application, such as Word, can send commands to others on the local machine, or even on remote machines. Hackers understand these subtle relationships, and craft applications to take advantage of them.

A talented hacker can quickly create powerful scripts in order to exploit a system.
