Examples include simple Unix kernel hacks, Internet worms, and Trojan horses in software utilities. Network attacks such as distributed denial of service (DDOS) and botnet- attacks are also described and illustrated using real examples from the past couple of decades. A Trojan horse program is similar to spyware except that it is packaged as another program. These programs are much like the ancient story of Troy where the Greeks presented the Trojans with a large wooden horse as a peace offering. While the city slept, Greek soldiers emerged from the horse .

Shop now. You might have read the last chapter on backdoors and thought to yourself, "I'd never run a program named Netcat or VNC on my machine, so I'm safe! Attackers with any modest level of skill will disguise the nasty backdoors we covered in the last chapter or hide them inside of other programs. That's the whole idea of a Trojan horse, which we define as follows:. A Trojan horse is a program that appears to have some useful or benign purpose, but really masks some hidden malicious code.

As you might expect, Trojan horses are called Trojans for short, and the verb referring to the act of planting a Trojan horse is to Trojanize or even simply to Trojan. If you recall your ancient Greek history, you'll remember that the original Trojan horse allowed an army to sneak right through a highly fortified gate.

Amazingly, the attacking army hid inside a giant wooden horse offered as a gift to the unsuspecting victims. It worked like a charm. In a similar fashion, today's Trojan horses try to sneak past computer security fortifications, such as firewalls, by employing like-minded trickery.

By looking like normal, happy software, Tro-jan horse programs are used for the following goals: Duping a user or system administrator into installing the Trojan horse in the first place. In this case, the Trojan horse and the unsuspecting user become the entry vehicle for the malicious software on the system.

Blending in with the "normal" programs running on a machine. The Trojan horse camouflages itself to appear to belong on the system so users and administrators blithely continue their activity, unaware of the malicious code's presence.

Many people often incorrectly refer to any program that gives remote control of or a remote command shell on a victim machine as a Trojan horse. This notion is mistaken. However, although these tools can be used as backdoors, by themselves they are not Trojan horses. If a program merely gives remote access, it is just a backdoor, as we discussed in Chapter 5.

On the other hand, if the attacker works to disguise these backdoor capabilities as some other benign program, then we are dealing with a true Trojan horse. Attackers have devised a myriad of methods for hiding malicious capabilities inside their wares on your computer.

These techniques include employing simple, yet highly effective naming games, using executable wrappers, attacking software distribution sites, manipulating source code, coopting software installed on your system, and even disguising items using polymorphic coding techniques.

As we discuss each of these elements throughout this chapter, remember the attackers' main goal: to disguise their malicious code so that users of the system and other programs running on the system do not realize what the attacker is up to. In this chapter, we'll discuss both widely used and cutting-edge techniques.

Keep in mind, however, that attackers are a creative and devious lot. They use the concepts we'll discover, but tweak them in innumerable ways to achieve maximum subterfuge. At the very simplest level of Trojan horse techniques, an attacker might merely alter the name of malicious code on a system so that it appears to belong on that machine.

By giving a backdoor program the same name of some other program you'd normally expect to be on your system, an attacker might be able to operate undetected. After all, only the lamest of attackers would run malicious code using the well-known name of that code, such as Netcat or VNC. Don't get me wrong, however. If a really dimwitted bad guy attacks my system and uses techniques that I can easily spot, I'm all for it.

That makes my job easier. I'm perfectly happy to catch any attacker when he or she makes a mistake of that magnitude, and, thankfully, I have found several instances of attackers calling a backdoor Netcat or even VNC.

However, we can't expect all of our adversaries to make such trivial errors, so let's investigate their naming games in more detail. One very simple Trojan horse naming technique used by attackers against Windows systems is to trick victims by creating a file name with a bunch of spaces in it to obscure the file's type. As you no doubt know, the three-letter suffix also known as an "extension" of a file name in Windows is supposed to indicate the file's type and which application should be used to view that file.

For example, executables have the. EXE suffix, whereas text files end in. The information security business has done a good job over the last decade of informing our users not to run executable attachments included in e-mail or those that appear on their hard drive. So, given users' fright and awe in the presence of EXE files, how could a malicious executable program be disguised as something benign, such as a simple text file?

An attacker could confuse a victim by naming a file with a bunch of spaces before its real suffix, like this:. EXE at the end of the name after all of the spaces makes the program executable, but the unwary user might not notice the. EXE suffix. If users look at such a file with the Windows Explorer file viewer, it'll appear that the file might just be text, as shown in Figure 6. For comparison to a benign file, the first line in Figure 6. Most users would have no qualms about double-clicking such a nice-looking, happy file.

The second line, however, is far more evil. Those innocent looking dots mean that the file name is actually longer than what is displayed. Figure 6. Of course the Explorer file viewer shows the second file's type as Application and displays an executable's icon next to the name instead of a text file icon.

Still, the vast majority of users would never notice these somewhat subtle distinctions. If this is a huge concern for the attackers, they could even configure the system so that an executable program type's icon actually appears as a. TXT icon. Alternatively, an attacker could choose a file type that is both executable and has an icon that looks quite similar to a text file, such as the Shell Scrap Object file type, with an.

SHS extension. SHS files are used to bundle together commonly copied and pasted text and pictures, as well as commands, for various Windows programs. The third line of Figure 6. SHS file. The fourth line of the figure shows a combination of these techniques: an. TXT file. You can easily see how a user could get duped into executing this type of file. Numerous file suffixes could be used to deliver and contain malicious code on a target machine.

Table 6. Many, but certainly not all, of these script types are tied to Windows machines, as the Windows operating system is freakishly obsessed with a file's type being stored in the suffix. However, the phenomenon is not limited to Windows. On UNIX systems, some program types are also indicated with a suffix, including.

PL, and. It's important to note, however, that UNIX doesn't put any special meaning into a file's suffix, unlike Windows. In Windows, the operating system uses the suffix to determine which application to use when opening a document. Still, any one of these file types in Table 6. Acrobat Plug-in, for extending the capabilities of Adobe's Acrobat file viewing tool.

Batch processing file, used to execute a series of contained commands in sequential order. Borland package libraries, containing chunks of shared code used in programs developed within the Delphi software language and environment. Compiled HTML Help file, which could include a link that would download and execute malicious code on a victim machine.

Command file, containing scripts or even executables for DOS and Windows systems. Windows Control Panel Extension, allowing new capabilities in your previously dull and monotonous control panels. Dynamic Link Library, executable code that is shared by numerous other programs on the system. Delphi Package Library, used to add bundled together shared libraries of code developed in the Delphi programming environment.

Device driver, used to extend the hardware support of a Windows machine, but could be abused to modify the kernel and completely control the victim machine.

Object Linking and Embedding OLE control, used to orchestrate the interaction of several programs on a Windows machine. Program Information File, used to tell Windows how to run a non-Windows application. Perl script, a powerful, high-level scripting language supported on most UNIX systems and some Windows machines. Shell Scrap Object file, a format used to hold frequently repeated commands, text, and pictures in Windows programs. System configuration file, normally used to establish system settings, but could be used by an attacker to reconfigure a victim machine.

Visual Basic Script, a scripting language built into many Windows machines. Virtual device driver, a device driver with direct access into a Windows kernel. Windows Media Audio file, used to store audio data, but has been exploited to carry a buffer overflow designed to execute malicious code embedded in the file. Windows Script File, designed to carry a variety of Windows script types. Windows Script Host Settings file, used to configure the script interpreter program on a Windows machine.

Red Hat Package Manager, used to bundle libraries, configuration files, and code for simpler installation on Linux systems. A UNIX shell script or shell archive file, used to carry sequences of commands for a UNIX shell, usually the bourne shell sh or bourne again shell bash. There sure are many suffixes that could contain executable code of some form. Your users are not going to be able to memorize every single item in this massive list.

Still, they should be wary of the biggies that are most often abused by bad guys, such as. SCR, and. These Trojan horse naming issues go beyond just putting a bunch of spaces between the name and its file extension on Windows systems.

We've just barely scratched the surface. Often, to fool a victim, attackers create another file and process with exactly the same name as an existing program installed on the machine, such as the UNIX init process. Init normally starts running all other processes while the system boots up. In this type of naming attack, you could actually see two processes named init running on your system: your normal init that's supposed to be there, and another Trojan horse named init by the attacker.
