Didier Stevens adds JSON output to onedump.py for extracting OneNote embedded files

Didier Stevens has added a --jsonoutput option to onedump.py, which lists every file embedded in one or more OneNote .one files as JSON. Piping that output into myjson-filter.py with -W hashvir writes each embedded file to disk, named by its SHA256 hash with a .vir extension. The post is a diary entry about a tool feature rather than a threat.

Last updated 3 November 2026. Facts come from our own stories, NVD and CISA KEV, MITRE ATT&CK and Wikidata, each named beside the fact; the introduction, when there is one, is from Wikipedia. We never show company logos.
