Traditional methods of virus detection involve identifying malware by comparing code in a program to the code of known virus types that have already been encountered, analyzed and recorded in a database – known as signature detection.

While useful and still in use, signature detection method has also became more limited, due to the development of new threats which exploded around the turn of the century and are continuing to emerge all the time.

To counter this problem, the heuristic model was specifically designed to spot suspicious characteristics that can be found in unknown, new viruses and modified versions of existing threats as well as known malware samples.

Cybercriminals are constantly developing new threats, and heuristic analysis is one of the only methods used to deal with the huge volume of these new threats seen daily.

Heuristic analysis is also one of the few methods capable of combating polymorphic viruses — the term for malicious code that constantly changes and adapts. Heuristic analysis is incorporated into advanced security solutions offered by companies like Kaspersky Labs to detect new threats before they cause harm, without the need for a specific signature.

How Does Heuristic Analysis Work?

Heuristic analysis can employ a number of different techniques. One heuristic method, known as static heuristic analysis, involves decompiling a suspect program and examining its source code. This code is then compared to viruses that are already known and are in the heuristic database. If a particular percentage of the source code matches anything in the heuristic database, the code is flagged as a possible threat.

Another method is known as dynamic heuristics. When scientists want to analyze something suspicious without endangering people, they contain the substance in a controlled environment like a secure lab and conduct tests. The process is similar for heuristic analysis — but in a virtual world.

It isolates the suspicious program or piece of code inside a specialized virtual machine — or sandbox — and gives the antivirus program a chance to test the code and simulate what would happen if the suspicious file was allowed to run. It examines each command as it's activated and looks for any suspicious behaviors, such as self-replication, overwriting files, and other actions that are common to viruses.

Potential Issues

Heuristic analysis is ideal for identifying new threats, but to be effective heuristics must be carefully tuned to provide the best possible detection of new threats but without generating false positives on perfectly innocent code.

For this reason, heuristic tools are often typically just one weapon in a sophisticated antivirus arsenal. They are typically deployed along with other methods of virus detection, such as signature analysis and other proactive technologies.

Heuristic analysis is a method of detecting viruses by examining code for suspicious properties. It was designed to spot unknown new viruses and modified versions of existing threats.

An antivirus tool is an essential component of most anti-malware suites. It must identify known and previously unseen malicious files with the goal of blocking them before they can cause damage. Though tools differ in the implementation of malware-detection mechanisms, they tend to incorporate the same virus detection techniques. Familiarity with these techniques can help you understand how antivirus software works.

Malware detection techniques employed by antivirus tools can be classified as follows:

Signature-based detection uses key aspects of an examined file to create a static fingerprint of known malware. The signature could represent a series of bytes in the file. It could also be a cryptographic hash of the file or its sections. This method of detecting malware has been an essential aspect of antivirus tools since their inception; it remains a part of many tools to date, though its importance is diminishing. A major limitation of signature-based detection is that, by itself, this method is unable to flag malicious files for which signatures have not yet been developed. With this in mind, modern attackers frequently mutate their creations to retain malicious functionality by changing the file’s signature.

Heuristics-based detection aims at generically detecting new malware by statically examining files for suspicious characteristics without an exact signature match. For instance, an antivirus tool might look for the presence of rare instructions or junk code in the examined file. The tool might also emulate running the file to see what it would do if executed, attempting to do this without noticeably slowing down the system. A single suspicious attribute might not be enough to flag the file as malicious. However, several such characteristics might exceed the expected risk threshold, leading the tool to classify the file as malware. The biggest downside of heuristics is it can inadvertently flag legitimate files as malicious.

Behavioral detection observes how the program executes, rather than merely emulating its execution. This approach attempts to identify malware by looking for suspicious behaviors, such as unpacking of malcode, modifying the hosts file or observing keystrokes. Noticing such actions allows an antivirus tool to detect the presence of previously unseen malware on the protected system. As with heuristics, each of these actions by itself might not be sufficient to classify the program as malware. However, taken together, they could be indicative of a malicious program. The use of behavioral techniques brings antivirus tools closer to the category of host intrusion prevention systems (HIPS), which have traditionally existed as a separate product category.

Cloud-based detection identifies malware by collecting data from protected computers while analyzing it on the provider's infrastructure, instead of performing the analysis locally. This is usually done by capturing the relevant details about the file and the context of its execution on the endpoint, and providing them to the cloud engine for processing. The local antivirus agent only needs to perform minimal processing. Moreover, the vendor's cloud engine can derive patterns related to malware characteristics and behavior by correlating data from multiple systems. In contrast, other antivirus components base decisions mostly on locally observed attributes and behaviors. A cloud-based antivirus engine allows individual users of the tool to benefit from the experiences of other members of the community.

Though the approaches above are listed under individual headings, the distinctions between various techniques are often blurred. For instance, the terms "heuristics-based" and "behavioral detection" are often used interchangeably. In addition, these methods—as well as signature detection—tend to play an active role when the tool incorporates cloud-based capabilities. To keep up with the intensifying flow of malware samples, antivirus vendors have to incorporate multiple layers into their tools; relying on a single approach is no longer a viable option.

A newer approach to AV is dynamic analysis heuristic monitoring, which uses a variety of techniques to spot the characteristics of a virus instead of attempting to make matches.
