Analyzes malicious Office documents by extracting and reviewing VBA macros and OLE/OOXML structure: auto-exec triggers, obfuscation, dropped payloads, and shell/PowerShell invocation. Activates for requests to analyze a malicious Word/Excel document, VBA macro, or maldoc.

Review the instructions the agent will receive before you install.
Do not use the document's "Enable Content" path to analyze it — never open a maldoc in Office. Extract and read the macro statically; detonate only in the isolated lab if needed.
oletools (pip install oletools) for olevba/oleid, or the bundled OLE/OOXML extractor.OOXML (.docm, .xlsm) is a ZIP; legacy (.doc, .xls) is OLE2. Macros live in a
vbaProject.bin OLE stream. Extract it:
python scripts/analyst.py extract maldoc.docm
Look for entry points that run without user action beyond enabling macros:
AutoOpen, Document_Open, AutoClose, Workbook_Open, Auto_Open, Document_Close
Identify execution and download primitives:
Shell, WScript.Shell, CreateObject, powershell, cmd /c
URLDownloadToFile, MSXML2.XMLHTTP, ADODB.Stream (drop to disk)
Environ, GetObject("winmgmts:") (WMI)
Maldocs commonly use Chr()/string concatenation, base64, and split-and-join. Resolve these to recover the real command and any URL or dropped path.
Pull URLs, dropped file paths, and the spawned command line. These become the report's IOCs and pivot points.

Analyzes API call traces from a sandbox or API monitor (JSON) to group calls by category, reconstruct high-level behaviors (process injection, file drops, network, crypto), and flag suspicious call sequences. Activates for requests to analyze an API trace, interpret sandbox API logs, or identify behavior from Win32/Native API calls.

Analyzes Windows Authenticode signatures on PE files: checking for a signature, reading the signer certificate chain, detecting revoked/expired/stolen certs, and recognizing signature-stripping and catalog-signing abuse. Activates for requests to analyze a code signature, verify Authenticode, or assess signer trust on a PE.

Analyzes Python-based malware packaged as PyInstaller/py2exe executables by detecting the packer, locating the embedded archive, and identifying bundled .pyc modules for extraction and decompilation. Activates for requests to analyze compiled Python malware, unpack a PyInstaller binary, or extract pyc modules from a frozen Python executable.

Analyzes cryptojacking/coinminer malware by extracting mining pool endpoints (stratum), wallet addresses, algorithm and miner identifiers (XMRig and forks), and persistence or resource-control settings from static strings and config. Activates for requests to analyze a cryptominer, extract mining pool and wallet IOCs, or identify coinminer configuration.
