Features
Indicators
PeStudio shows Indicators as a human-friendly result of the analyzed image. Indicators are grouped into categories according to their severity. Indicators show the potential and the anomalies of the application being analyzed. The classifications are based on XML files provided with PeStudio. By editing the XML file, one can customize the Indicators shown and their severity. Among the indicators, PeStudio shows when an image is compressed using UPX or MPRESS. PeStudio helps you to define the trustworthiness of the application being analyzed.
Virus Detection
PeStudio can query Antivirus engines hosted by Virustotal for the file being analyzed. This feature only sends the MD5 of the file being analyzed. This feature can be switched ON or OFF using an XML file included with PeStudio. PeStudio helps you to determine how suspicious the file being analyzed is.
Imports
Even a suspicious binary or malware file must interact with the operating system in order to perform its activity. For this to be possible, a certain amount of libraries must be used. PeStudio retrieves the libraries and the functions used by the image. PeStudio also includes an XML file that is used to blacklist functions (e.g. Registry, Process, Thead, File, …). The blacklist file can be customized and extended according to your own needs. PeStudio shows the intent and purpose of the application analyzed.
Resources
Executable files typically not only contain code but also many kinds of data types. Resources sections are commonly used to host different Windows built-in items (e.g. icons, strings, dialogs, menus) and custom data. PeStudio analyzes the resources of the file being analyzed and detects embedded items (e.g. EXE, DLL, SYS, PDF, CAB, ZIP, JAR, …).
