The author is not responsible for any abuse of this information. It is intended for educational use only. You may be quite shocked at how vulnerable you are! As an afterthought I added a section on database access due to a number of requests. The majority of successful attacks on computer systems via the Internet can be traced to exploitation of security flaws in software and operating systems. These few software vulnerabilities account for the majority of successful attacks, simply because attackers are opportunistic – taking the easiest and most convenient route. They exploit the best-known flaws with the most effective and widely available attack tools. Most software, including operating systems and applications, comes with installation scripts or installation programs. The goal of these installation programs is to get the systems installed as quickly as possible, with the most useful functions enabled, with the least amount of work being performed by the administrator. To accomplish this goal, the scripts typically install more components than most users need. The vendor philosophy is that it is better to enable functions that are not needed, than to make the user install additional functions when they are needed. This approach, although convenient for the user, creates many of the most dangerous security vulnerabilities because users do not actively maintain and patch software components they don’t use. Furthermore, many users fail to realize what is actually installed, leaving dangerous samples on a system simply because users do not know they are there. Those unpatched services provide paths for attackers to take over computers. For operating systems, default installations nearly always include extraneous services and corresponding open ports. Attackers break into systems via these ports. In most cases the fewer ports you have open, the fewer avenues an attacker can use to compromise your network. For applications, default installations usually include unneeded sample programs or scripts. One of the most serious vulnerabilities with web servers is sample scripts; attackers use these scripts to compromise the system or gain information about it. In most cases, the system administrator whose system is compromised did not realize that the sample scripts were installed. Sample scripts are a problem because they usually do not go through the same quality control process as other software. In fact they are shockingly poorly written in many cases. Error checking is often forgotten and the sample scripts offer a fertile ground for buffer overflow attacks. The simplest means to gain access to a system is by simple file and printer sharing. This is used to allow others on say, a home local area network share files, printers, and internet connections. If the computer having file and printer sharing enabled, this in fact allows these resources to be shared, and on offer, to the entire internet! This is largely due to the fact that Netbios was originally intended for use on local area networks (LAN’s), where trusted sharing of resources made sense for many reasons. It was never intended to ‘go global’. First, search using a Netbios scanner, for a system with sharing enabled. A program such as Netbrute, by Raw Logic Software, is ideal. These programs can help the would-be hacker, as well as the network administrator. Run the scan over a subnet at a time, for example an IP address range from 80.1.1.1 to 80.1.1.254. Choose a system which has, preferably, it’s whole hard disk
