Espresso Service

This Assemblyline service analyzes Java JAR files. All classes are extracted, decompiled and analyzed for malicious behavior.

NOTE: This service does not require you to buy any licence and is preinstalled and working after a default installation

Execution

The service extracts all the files from inside the Jar then performs analysis of the different files for malicious behavior. For all the .java files found inside the jar, the service will run the CFR Decompiler tool on it to get back a human readable version of the code.

When a file inside the Jar is noted as potentially malicious, the file is added as a supplementary file to the results so the analysts can see the content of that file.
