-# Check over ADB
+# ADB Analysis Removed
 
-In order to check an Android device over the [Android Debug Bridge (adb)](https://developer.android.com/studio/command-line/adb) you will first need to install [Android SDK Platform Tools](https://developer.android.com/studio/releases/platform-tools). If you have installed [Android Studio](https://developer.android.com/studio/) you should already have access to `adb` and other utilities.
+The ability to analyze Android devices directly over the [Android Debug Bridge (adb)](https://developer.android.com/studio/command-line/adb) has been removed from MVT.
 
-While many Linux distributions already package Android Platform Tools (for example `android-platform-tools-base` on Debian), it is preferable to install the most recent version from the official website. Packaged versions might be outdated and incompatible with most recent Android handsets.
-
-Next you will need to enable debugging on the Android device you are testing. [Please follow the official instructions on how to do so.](https://developer.android.com/studio/command-line/adb)
-
-## Connecting over USB
-
-The easiest way to check the device is over a USB transport. You will need to have USB debugging enabled and the device plugged into your computer. If everything is configured appropriately you should see your device when launching the command `adb devices`.
-
-Now you can try launching MVT with:
+Use [AndroidQF](https://github.com/mvt-project/androidqf) to collect forensic artifacts from an Android device, then analyze the collected output with:
 
 ```bash
-mvt-android check-adb --output /path/to/results
+mvt-android check-androidqf /path/to/androidqf-output
 ```
 
-!!! warning
-    The `check-adb` command is deprecated and will be removed in a future release.
-    Whenever possible, prefer acquiring device data using the AndroidQF project (https://github.com/mvt-project/androidqf/) and then analyze those acquisitions with MVT.
+For a standalone Android bug report, use:
 
-    Running `mvt-android check-adb` will also emit a runtime deprecation warning advising you to migrate to AndroidQF.
+```bash
+mvt-android check-bugreport /path/to/bugreport.zip
+```
 
-If you have previously started an adb daemon MVT will alert you and require you to kill it with `adb kill-server` and relaunch the command.

-    The `mvt-android check-adb` command has been deprecated and removed from MVT.
-
-The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT due to several technical and forensic limitations.
-
-## Reasons for Deprecation
+## Reasons for Removal
 
 1. **Inconsistent Data Collection Across Devices**
-   Android devices vary significantly in their system architecture, security policies, and available diagnostic logs. This inconsistency makes it difficult to ensure that MVT can reliably collect necessary forensic data across all devices.
+   Android devices vary significantly in system architecture, security policy, and diagnostic log availability. This made it difficult to collect reliable forensic data across devices.
 
 2. **Incomplete Forensic Data Acquisition**
-   The `check-adb` command did not retrieve a full forensic snapshot of all available data on the device. For example, critical logs such as the **full bugreport** were not systematically collected, leading to potential gaps in forensic analysis. This can be a serious problem in scenarios where the analyst only had one time access to the Android device.
+   Direct ADB analysis did not retrieve a complete forensic snapshot. Critical artifacts such as full bug reports could be missing.
 
-4. **Code Duplication and Difficulty Ensuring Consistent Behavior Across Sources**
-    Similar forensic data such as "dumpsys" logs were being loaded and parsed by MVT's ADB, AndroidQF and Bugreport commands. Multiple modules were needed to handle each source format which created duplication leading to inconsistent
-    behavior and difficulties in maintaining the code base.
+3. **Duplicated Analysis Paths**
+   Similar artifacts were parsed through separate ADB, AndroidQF, and bugreport modules, which made behavior harder to keep consistent.
 
-5. **Alignment with iOS Workflow**
-   MVT’s forensic workflow for iOS relies on pre-extracted artifacts, such as iTunes backups or filesystem dumps, rather than preforming commands or interactions directly on a live device. Removing the ADB functionality ensures a more consistent methodology across both Android and iOS mobile forensic.
-
-## Alternative: Using AndroidQF for Forensic Data Collection
-
-To replace the deprecated ADB-based approach, forensic analysts should use [AndroidQF](https://github.com/mvt-project/androidqf) for comprehensive data collection, followed by MVT for forensic analysis. The workflow is outlined in the MVT [Android methodology](./methodology.md)
+4. **Workflow Consistency**
+   MVT now focuses on analyzing acquired artifacts rather than interacting with live devices directly.

-    MVT will likely warn you it was unable to download certain installed packages. There is no reason to be alarmed: this is typically expected behavior when MVT attempts to download a system package it has no privileges to access.
-
-Optionally, you can decide to enable lookups of the SHA256 hash of all the extracted APKs on [VirusTotal](https://www.virustotal.com). While these lookups do not provide any conclusive assessment on all of the extracted APKs, they might highlight any known malicious ones:
-
-```bash
-MVT_VT_API_KEY=<key> mvt-android download-apks --output /path/to/folder --virustotal

-
-Please note that in order to use VirusTotal lookups you are required to provide your own API key through the `MVT_VT_API_KEY` environment variable. You should also note that VirusTotal enforces strict API usage. Be mindful that MVT might consume your hourly search quota.

+# Check Android Intrusion Logs
+
+Recent versions of Android can produce structured *Intrusion Logs* — newline-delimited JSON records derived from the platform's [SecurityLog API](https://developer.android.com/reference/android/app/admin/SecurityLog). Intrusion Logging is offered as a new option under Android's **Advanced Protection Mode**, which users can opt into on their device; no MDM or device-policy configuration is required. When enabled, these logs provide a high-fidelity record of process starts, DNS queries, outbound network connections, ADB activity, keyguard events, and other security-relevant operations. The initial Intrusion Logging feature was released for Android 16 in May 2026. The feature and supported events is likely to be expanded over time.
+
+For background on how this data source was introduced and why it is forensically valuable, see the Amnesty International Security Lab announcement: [Android Intrusion Logging as a new source of data for consensual forensic analysis](https://securitylab.amnesty.org/latest/2026/05/android-intrusion-logging-as-a-new-source-of-data-for-consensual-forensic-analysis/).
+
+## Recommended workflow: collect with AndroidQF
+
+[AndroidQF](https://github.com/mvt-project/androidqf) is the recommended way to acquire data from an Android device for analysis with MVT. During acquisition AndroidQF will prompt the user to also collect intrusion logs from the device, and writes them into an `intrusion-logs/` subdirectory of the acquisition output.
+
+When you analyse such an acquisition with `mvt-android check-androidqf`, MVT automatically detects the `intrusion-logs/` directory and runs the same intrusion-log checks described below — there is no need to invoke a separate command:
+
+```bash
+mvt-android check-androidqf --output /path/to/results/ /path/to/androidqf-output/
+```
+
+The device timezone is read from the AndroidQF acquisition (`getprop.txt`) and applied to event timestamps automatically.
+
+## Standalone command: `check-intrusion-logs`
+
+The `mvt-android check-intrusion-logs` command runs the intrusion-log analysis directly against a set of log files. Prefer the AndroidQF workflow above; use the standalone command when the intrusion logs were collected outside of an AndroidQF acquisition, or when re-analysing only a set of intrusion logs.
+
+## Expected input
+
+`check-intrusion-logs` accepts either:
+
+- a **directory** containing one or more `.txt` files (recursively), or
+- a **`.zip` archive** containing such `.txt` files (nested `.zip` archives are also walked).
+
+Each `.txt` file is expected to contain newline-delimited JSON, with one JSON object per line. Each object wraps a single event under a top-level key indicating its type, for example:
+
+```json
+{"dns_event": {"event_time": 1746979200000, "hostname": "example.com", "ip_addresses": ["93.184.216.34"], "package_name": "com.example.app"}}
+{"connect_event": {"event_time": 1746979201000, "ip_address": "93.184.216.34", "port": 443, "package_name": "com.example.app"}}
+{"security_event": {"event_time": 1746979202000, "tag": 210005, "data": ["..."]}}
+```
+
+Identical events that appear across multiple overlapping log files (e.g. daily rotations) are de-duplicated on a first-seen basis.
+
+## Running the analysis
+
+```bash
+mvt-android check-intrusion-logs --output /path/to/results/ /path/to/intrusion-logs/
+```
+
+A `.zip` archive can be passed directly in place of the directory:
+
+```bash
+mvt-android check-intrusion-logs --output /path/to/results/ /path/to/intrusion-logs.zip
+```
+
+### Options
+
+| Option | Description |
+| --- | --- |
+| `-i, --iocs PATH` | Path to a STIX2 indicator file. May be passed multiple times. |
+| `-o, --output PATH` | Directory where JSON results and the timeline CSV will be written. |
+| `-l, --list-modules` | List the available intrusion-log modules and exit. |
+| `-m, --module NAME` | Run a single module (e.g. `DnsEvent`) instead of all of them. |
+| `-t, --timezone TZ` | IANA timezone name for the device (e.g. `Europe/Paris`). When set, event timestamps are converted to the device's local time instead of UTC. |
+| `-v, --verbose` | Verbose logging. |
+
+## Modules
+
+The command runs the following modules over the parsed events:
+
+- **`DnsEvent`** — DNS resolution events. Hostnames and resolved IP addresses are checked against domain indicators, and the requesting `package_name` is checked against app-identifier indicators.
+- **`ConnectEvent`** — Outbound network connection events. Destination IPs (with localhost addresses skipped) are checked against domain indicators, and `package_name` is checked against app-identifier indicators.
+- **`SecurityEvent`** — Security log events keyed by Android `SecurityLog` tag IDs (e.g. `app_process_start`, `adb_shell_cmd`, `keyguard_dismissed`, `os_startup`, `cert_*` events). These are surfaced in the timeline to help reconstruct device activity around suspected events.
+
+All three modules share a single pre-parsing pass over the input, so adding more modules in the future does not multiply I/O cost. Additional modules will be added in the future to support new event types which are generated by the Intrusion Logging feature.
+
+## Interpreting results
+
+A successful IOC match raises a `CRITICAL` alert that includes the matched indicator, the offending event, and the event timestamp. Alerts are summarised at the end of the run and persisted alongside the per-module JSON results.
+
+When `--timezone` is provided, timestamps in the timeline and JSON output reflect the device's local wall-clock time. Otherwise timestamps are in UTC, consistent with the rest of MVT.
+
+## Limitations
+
+- This page assumes the intrusion logs have already been collected from the device. The recommended collection path is via AndroidQF (see above); intrusion logging itself must have been enabled on the device beforehand by opting into Android's Advanced Protection mode and also enabling the optional Intrusion Logging feature (see the [Amnesty blog post](https://securitylab.amnesty.org/latest/2026/05/android-intrusion-logging-as-a-new-source-of-data-for-consensual-forensic-analysis/) for details).
+- As with all IOC-based analysis, public indicators alone are not sufficient to conclude that a device is uncompromised. See the [Indicators of Compromise](../iocs.md) page for context.

-## Check the device over Android Debug Bridge
+## Android Intrusion Logs
 
-The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT.
+On devices where the user has opted into Android's [**Advanced Protection Mode**](https://support.google.com/android/answer/16339980) and turned on the optional Intrusion Logging featrue, Android can create and archive structured *Intrusion Logs* in an encrypted format. These logs record DNS queries, outbound network connections, process starts, ADB activity and other security-relevant events, and are a high-fidelity complement to the rest of an AndroidQF acquisition. The logs are generated on-device and encrypted before being stored in the Google account associated with the device. The encryption key is protected by the user device PIN. The intrusion log data is not accessible to Google.
 
-See the [Android ADB documentation](./adb.md) for more information.
+AndroidQF will prompt the user to download, decrypt and collect device intrusion logs as part of an acquisition. When they are present, `mvt-android check-androidqf` will automatically run the intrusion-log checks alongside the other AndroidQF modules — no extra command is required. This is the recommended workflow for Android forensic analysis with MVT.
+
+For cases where intrusion logs were collected outside of an AndroidQF acquisition, the standalone `mvt-android check-intrusion-logs` command can analyse them directly. See [Check Android Intrusion Logs](intrusion_logs.md) for details, and the [feature announcment from Amnesty International's Security Lab](https://securitylab.amnesty.org/latest/2026/05/android-intrusion-logging-as-a-new-source-of-data-for-consensual-forensic-analysis/) for background on the data source.

+## Android Debug Bridge analysis removed

+The ability to analyze Android devices directly over ADB has been removed from MVT. Direct extraction of data from ADB was error-prone and frequently resulted in inconsistent data collection between ADB and AndroidQF acquisitions. Use AndroidQF for device acquisition and `mvt-android check-androidqf` for analysis.

+## Module dependencies
+
+Modules can require other modules to run first by declaring their classes in
+`dependencies`. The command runner uses a stable topological ordering, so the
+existing module list order is preserved wherever dependency constraints allow.
+
+```python
+class DependentModule(MVTModule):
+    dependencies = (PrerequisiteModule,)
+
+    def run(self):
+        prerequisite_results = self.get_dependency_results(PrerequisiteModule)

+
+Selecting a single module also runs its transitive dependencies. If a dependency
+is unavailable or the dependency graph contains a cycle, the command logs a
+warning and does not run any modules.
+
+## Custom modules
+
+Module-running `check-*` commands can load custom modules from Python files that
+are not installed as part of MVT. Load one file with:
+
+```bash
+mvt-ios check-backup --load-module ./example_module.py --output ./out ./backup
+```
+
+You can also load a folder. MVT loads non-hidden top-level `*.py` files in
+sorted order and skips `__init__.py`:
+
+```bash
+mvt-ios check-fs --load-module ./custom_modules ./filesystem-dump
+```
+
+Set `MVT_CUSTOM_MODULES` to load a folder for every module-running command. This
+folder is loaded before any `--load-module` path:
+
+```bash
+MVT_CUSTOM_MODULES=./custom_modules mvt-android check-bugreport ./bugreport.zip
+```
+
+Custom modules are normal `MVTModule` subclasses:
+
+```python
+from mvt.common.module import MVTModule
+
+
+class ExampleCustomModule(MVTModule):
+    supported_commands = (("ios", "check-backup"), ("ios", "check-fs"))
+    slug = "example_custom_module"
+
+    def run(self):
+        self.results = [{"message": "custom module ran"}]
+
+    def check_indicators(self):
+        pass
+
+    def serialize(self, result):
+        return None
+```
+
+Use `supported_commands` to restrict a module to specific platform/command
+pairs. Missing or empty `supported_commands` means the module is available to
+all commands, which keeps older modules compatible. Supported pairs are:
+
+```python
+("ios", "check-backup")
+("ios", "check-fs")
+("ios", "check-iocs")
+("android", "check-backup")
+("android", "check-bugreport")
+("android", "check-androidqf")
+("android", "check-intrusion-logs")
+("android", "check-iocs")
+```
+
+Custom modules can depend on existing MVT module classes. Dependencies are
+resolved with the same ordering logic as built-in modules, and custom modules
+are appended after built-ins before ordering:
+
+```python
+from mvt.common.module import MVTModule
+from mvt.ios.modules.backup.manifest import Manifest
+
+

+    ----------------
+    Log files can be large and are shared by every module in this package.
+    To avoid re-reading and re-parsing the same files N times (once per
+    module), the command layer should call :meth:`load_all_events` exactly
+    once and then assign the returned dict to the ``il_events_by_type``
+    attribute of every module instance **before** calling ``run_module``.
+
+    When ``il_events_by_type`` is populated:
+    * :meth:`collect_txt` becomes a no-op (no disk I/O).
+    * :meth:`parse_collected_txt` iterates the in-memory list for the
+      requested event type instead of re-parsing raw text.
+
+    Modules that are used standalone (e.g. in tests) still work as before
+    because ``il_events_by_type`` defaults to ``None``, which preserves the
+    original file-loading code path.
