Refresh the iLEAPP and ALEAPP artifact mappings by abrignoni · Pull Request #8036 · sleuthkit/autopsy

abrignoni · 2026-09-14T17:39:14Z

Updates both artifact attribute reference files to match what current iLEAPP and ALEAPP produce, while keeping the file names the bundled v1.18.6 and v3.1.6 binaries still write, so nothing that binds today stops binding. This replaces an earlier version of this change that dropped those names.

Measured with the module's own matching logic, against TSV output from real runs and against the file names the bundled binaries produce:

	bundled v1.18.6 and v3.1.6	v2026.4.0
before	44	9
after	46	40

Three entries matched a bundled binary's file name but none of its columns. Autopsy adds the comment attribute regardless of column matches, so each of those emitted an artifact per row carrying no content. Those are fixed.

required is "no" on every column. An empty required datetime or numeric column discards the whole row, and a missing column is skipped either way.

ACCOUNT_RELATIONSHIPS is keyed on file names, so the iOS messages entry needs a key there to keep its account relationships.

Summary by CodeRabbit

Enhancements
- Consolidated browser artifact mappings across supported browser variants.
- Updated call, SMS, MMS, search, account, and installed-app artifact fields.
- Expanded iOS evidence coverage with Biome, location-cache, and Wi‑Fi data.
- Improved handling of incomplete source data through more flexible field mappings.
- Corrected descriptions for Edge search terms and GMS-installed apps.
Removed Support
- Removed several messaging-app and location-related mappings from the aLeapp reference.

Updates both artifact attribute reference files so the entries match the file names and column headers current iLEAPP and ALEAPP releases produce, pinned to v2026.4.0. Measured against TSV output from real runs: iOS entries that bind go from 6 to 25, Android from 3 to 15, and nine mapped columns that pointed at headers which no longer exist drop to zero. required is now "no" on every column. An empty required column discards the whole row, and a missing column is skipped either way.

📝 Walkthrough

Walkthrough

The two artifact-reference XML files were rewritten. The changes consolidate mappings, rename files and columns, add attributes, remove obsolete mappings, and make many attributes optional.

Changes

Artifact reference updates

Layer / File(s)	Summary
aLeapp core mappings `Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/aleapp-artifact-attribute-reference.xml`	Call, Google Play, SMS, MMS, account, installed-application, and search mappings were renamed, remapped, and expanded. Optional attributes and legacy filename mappings remain.
aLeapp browser mappings `Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/aleapp-artifact-attribute-reference.xml`	Generic browser mappings were added for bookmarks, cookies, history, searches, logins, offline pages, and top sites. Browser-, Chrome-, and Edge-specific mappings remain.
iLeapp application and communication mappings `Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/ileapp-artifact-attribute-reference.xml`	Application, Bluetooth, call, notification, calendar, Safari, and SMS mappings were renamed or remapped. Additional `null` columns were added, and many attributes became optional.
iLeapp system and location mappings `Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/ileapp-artifact-attribute-reference.xml`	KnowledgeC and Biome mappings were consolidated. Installed-app, torch, location, and Wi-Fi mappings were replaced or expanded with new artifact names and attributes.

The refresh matched what current iLEAPP and ALEAPP produce but dropped the file names the bundled v1.18.6 and v3.1.6 binaries still write, so entries that bind today stopped binding. Adds those names back as separate entries, which costs nothing at run time because a column absent from the header row is skipped. Also fixes three entries that matched a bundled binary's file name while matching none of its columns. The comment attribute is added regardless of column matches, so each of those emitted an artifact per row carrying no content.

The Edge search terms entry was commented "Chrome Search Terms" and the GMS entry "Installed Apps GSM". Both strings become a TSK_COMMENT on every row, so they name the wrong browser and the wrong acronym in the report.

3-203: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

15 of the 19 legacy-style mapping entries in this file reference file-name stems that the bundled ALEAPP v3.1.6 binary does not produce. The bundled code instead emits names such as accounts ce {uid}.tsv, authtokens {uid}.tsv, accounts de {uid}.tsv, and installed apps - GMS{usernum}.tsv, not the mapped Accounts_ce.tsv, Authentication tokens.tsv, Accounts_de.tsv, or Installedapps*.tsv/Google Quick Search Queries.tsv names. Despite the PR's stated goal of retaining compatibility with the bundled binary, these mappings will never match its actual output, so the corresponding artifacts will silently never be created when using the bundled ALEAPP v3.1.6 tool. Update these entries to the file-name stems actually produced by the bundled binary (accounting for the per-user UID/usernum suffixes where applicable).

🟡 Minor · Add both iLEAPP SMS relationship keys. · Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/ileapp-artifact-attribute-reference.xml:159-187

159-187: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Add both iLEAPP SMS relationship keys. LeappFileProcessor looks up ACCOUNT_RELATIONSHIPS by the lowercased output filename. SMS.tsv and SMS & iMessage - Messages.tsv do not match existing keys, so both use norelationship instead of creating message-account relationships. Add sms.tsv and sms & imessage - messages.tsv with the message relationship. Existing aLeAPP message mappings remain covered.

abrignoni · 2026-09-15T19:43:39Z

@coderabbitai this is a change to ACCOUNT_RELATIONSHIPS in LeappFileProcessor, so it is out of scope for this XML-only PR, and it should not be added as written. The iOS SMS.tsv and SMS & iMessage - Messages.tsv mappings carry no sender, recipient, or direction column. With those keys set to message, createMessageRelationship substitutes the device as both parties on every iOS message and creates a self relationship, which is worse than the plain message artifact they produce now. Adding the keys needs iOS sender and recipient mapping first, which is a separate change.

coderabbitai · 2026-09-15T19:44:04Z

Tip

For best results, initiate chat on the files or code changes.

@abrignoni, thanks for the clarification. I withdraw the finding.

ACCOUNT_RELATIONSHIPS is outside this XML-only PR. The current iOS message mappings do not provide sender, recipient, or direction data. Therefore, mapping SMS.tsv or SMS & iMessage - Messages.tsv to message would create incorrect device-to-device self relationships. A separate change must add the required iOS participant mappings before it adds relationship support.

Would you like me to open a follow-up issue for that separate work? Also, please confirm if you want the obsolete learning that recommended those relationship keys removed.

Learning: In `Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/ileapp-artifact-attribute-reference.xml`, the iOS `SMS.tsv` and `SMS & iMessage - Messages.tsv` mappings do not include sender, recipient, or direction columns. Do not add normalized `message` entries for these files to `LeappFileProcessor.ACCOUNT_RELATIONSHIPS` until a separate change maps the required iOS participants. Otherwise, `createMessageRelationship` substitutes the device for both parties and creates incorrect self relationships.

Timestamp: 2026-09-14T20:03:36.922Z
Learning: In the iLeapp analyzer, `LeappFileProcessor.ACCOUNT_RELATIONSHIPS` normalizes filenames by trimming and lowercasing them. The existing key `sms - imessage.tsv` does not match the shipped XML filename `SMS & iMessage - Messages.tsv`. The iLeapp XML retains both `SMS.tsv` and `SMS & iMessage - Messages.tsv` for different bundled binary outputs, so a Java follow-up must map both normalized filenames to `message` to enable `createMessageRelationship`.
