Review SMS / iMessage / calls / contacts / mail / third-party messengers recovered from an iOS acquisition to surface targeted social-engineering, suspicious delivery URLs, unknown correspondents, and deleted-but-recoverable records.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Communications Analysis ## When to Use - Spyware hunt surfaced a message-vector hit (Pegasus one-click / zero-click) - Incident involves social engineering, BEC, sextortion, or harassment - Scoping who the subject communicated with during an incident window - Recovering deleted messages / contacts / call history ## Goal Reconstruct the subject's communication graph, surface anomalies, and extract durable evidence for any message / call that matters. ## Procedure ### 1. Inventory what's present Before digging in, confirm what communication surfaces exist on this acquisition: ``` mvt_installed_apps ``` - Built-in (always): Messages (SMS/iMessage), Phone, Mail, FaceTime - Common third-party: WhatsApp, Signal, Telegram, Wire, Wickr, WeChat, Line, Viber, Discord, Slack, Teams, iMessage with Business, Hangouts / Google Chat, Messenger `ios_backup_list domain_filter="AppDomainGroup-group.net.whispersystems.signal.group"` and similar for any you want to investigate. ### 2. SMS / iMessage ``` mvt_sms_messages(source, iocs=<optional STIX>) ``` Extract `sms.db` for full-fidelity analysis: ``` ios_backup_extract(backup_dir, domain="HomeDomain", …

How to install
mdr add dreadnode/capabilities/communications-analysis@sha256:a185b02c5ceea035The line at the top of this page pins the label git:20260504.2a64374, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
