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.

Google Quick Search Queries maps both File Timestamp and File Modified Time, the name the column has on ALEAPP main. Autopsy skips whichever one a TSV does not have.

Bluetooth Paired LE no longer maps Last Connection Time to an access time. The bundled and current iLEAPP both write the raw database value there, which the datetime parser cannot read, so it never produced a value.

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

    • Updated Android artifact mappings for call logs, messaging, browser exports, account and token data, installed apps, and Google searches.
    • Expanded iOS evidence mappings for Biome, location-cache, and Wi‑Fi data.
    • Made mapped fields optional and added handling for columns without a corresponding artifact field.
  • Removed Support

    • Removed mappings for several older app-specific messaging, contact, call, location, and track exports, along with legacy account, token, and messaging filename variants.

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

The aLeapp and iLeapp artifact-reference catalogs were rewritten. They now map revised export filenames and columns to Autopsy artifacts and attributes, and include added or removed mappings and changes to attribute optionality.

Changes: Artifact reference updates

Layer / File(s) Summary
aLeapp artifact mappings
Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/aleapp-artifact-attribute-reference.xml
The catalog now maps call logs, searches, messages, browser exports, account and token data, and installed-app data. All mapped attributes are optional, and numerous older export mappings were removed.
iLeapp activity and communication mappings
Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/ileapp-artifact-attribute-reference.xml
Application, Bluetooth, call, usage, notification, browser, calendar, and messaging mappings were renamed or revised. New unmapped columns use null attributes, and many mapped attributes are optional.
iLeapp system and location mappings
Core/src/org/sleuthkit/autopsy/modules/leappanalyzers/ileapp-artifact-attribute-reference.xml
KnowledgeC mappings were consolidated, and Biome mappings were added. Installed-app, torch, location, and Wi-Fi mappings were revised.

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).

The SMS Messages Contact ID column is the provider's contacts row id
(sms.person), not a phone number, so it is no longer mapped to
TSK_PHONE_NUMBER_TO. The column is left unmapped.

🟡 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.

@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.

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.

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`.
