Malware Analysis

Our expert analysis augmented by our SAAS solution allows timely and accurate reverse engineering of potentially malicious code.

What is Malware Analysis?

Malware analysis is the process of understanding the behavior and purpose of a suspicious file or URL. The output of the analysis aids in the detection and mitigation of the potential threat to your business. The key benefit of this type of analysis is that it can help the incident responders and security analysts effectively conduct their jobs. You can analyze threats by level of severity as well as uncover hidden indicators of compromise that should be blocked. There are several different types of malware analysis.

Types of Malware Analysis

There are two main types of malware analysis which are static analysis and dynamic analysis but you may also combine the two and create a hybrid analysis approach. Static Analysis does not require that code is actually run but instead static analysis examines the file for signs of malicious intent. This type of analysis can be useful to identify malicious infrastructure, libraries, or packed files. The main issue with static analysis is that it does not actually run the code so sophisticated malware can include malicious runtime behavior that can go undetected.

Dynamic Analysis executes suspected malicious code in a safe environment called a sandbox which ensures that the code does not actually negatively impact your systems. This type of analysis provides security engineers and incident responders a deeper visibility to the potential threat and allows them to uncover the true nature of the threat. This also is a time effective model because it eliminates the time it would take to reverse engineer a file to discover the malicious code. These days adversaries are getting smarter and smarter so some sophisticated malware include conditions that allow the malware to remain dormant inside sandboxes and run only when certain conditions are met.

Often the best approach is to use a combination of Static Analysis and Dynamic Analysis to provide your security team the best of both worlds.

How Cosaint Cyber® Can Help

If you have a security breach or simply need some data analyzed to see if there is potential for malware in your system we can help. We run a full diagnostic to provide you more insight to the potential threat and give you steps to follow to secure your system. Malware analysis can help expose behavior and artifacts that threat hunters can use to find similar activity, such as access to a particular network connection, port or domain. If anything is found teams can then utilize this data to find similar threats throughout your system. We also offer fully automated analysis which will quickly and simply assess suspicious files. The analysis can determine potential repercussions if the malware were to infiltrate the network and then produce an easy to read report that provides fast answers for your security teams. Fully automated analysis is the best way to process malware at scale.
