pestudio implements a rich set of features that is especially designed to retrieve every single detail of any executable file. Results are checked against the Microsoft specification. Additionally, the content of the file being analyzed is checked against several white and black lists and thresholds. pestudio can query Antivirus engines hosted by Virustotal. Only the MD5 of the file being analyzed is sent. This feature can be switched ON or OFF using an XML file included with pestudio. pestudio retrieves the libraries and the functions referenced. Several XML files are used to blacklist functions (e.g. Registry, Process, Thread, File, etc). Blacklist files can be customized and extended according to your own needs. pestudio brings out the intent and purpose of the application analyzed. pestudio detects many embedded file types (e.g. EXE, DLL, SYS, PDF, CAB, ZIP, JAR, etc ). Detected items can be saved to a file, allowing therefore the possibility of further analysis. pestudio runs from the Graphical User Interface (GUI) as well as from the Command prompt (CLI). Running pestudio from the prompt offerts the possibillty to analyze executable file and to create associated XML output files in a batch mode.
