Portex

Welcome to PortEx

PortEx is a Java library for static malware analysis of portable executable files. Its focus is on PE malformation robustness and anomaly detection. PortEx is written in Java and Scala, and targeted at Java applications.

Features

• Reading Header information from: MSDOS Header, COFF File Header, Optional Header, Section Table
• Reading standard section formats: import section, resource section, export section, debug section, relocations, delay-load imports
• Dumping of sections, overlay, embedded ZIP, JAR or .class files
• Scanning for file anomalies, including structural anomalies, deprecated, reserved, wrong or non-default values. See here for a full list of anomalies
• Visualize a PE file's structure as it is on disk and visualize the local entropies of a file
• Calculate Shannon Entropy for files and sections
• Calculate hash values for files and sections
• Scan for PEiD signatures or your own signature database
• Scan for Jar to EXE wrapper (e.g. exe4j, jsmooth, jar2exe, launch4j)
• Extract Unicode and ASCII strings contained in the file
• Overlay detection and dumping
• Extract ICO files from resource section
