This page is a deep reference for non tech users on browser forensics—where common artifacts live, how they are stored, what they can and cannot prove, and how examiners convert raw browser data into a defensible activity timeline. It is OS-agnostic where possible and includes both Windows and macOS paths.
“Internet history analysis” in computer forensics typically includes more than a browser’s visible History page. The phrase commonly refers to a collection of persisted records stored in databases and cache structures: visited URLs, typed searches (where available), downloads, cookies/session state, autofill/form artifacts, and remnants of page content.
In practice, examiners treat browser data as one layer of an activity model and corroborate it against OS artifacts such as link files, jump lists, recent items, shellbags, Spotlight indexing, and other user-activity traces (see Windows forensic artifacts for user activity for a complementary layer).
Note: Some “search terms” appear indirectly via URL query parameters (e.g., q=...) or separate form/autofill artifacts. Availability depends on the browser, settings, and profile state.
Download artifacts become substantially more probative when correlated to file system metadata and OS-level recent-file usage traces.
Cookies can show authentication state, site affinity, and approximate usage windows. They do not reliably prove a specific user identity without supporting evidence.
Cache artifacts are volatile and prone to eviction. SSD TRIM and normal cache rotation can remove them quickly.
Examiners should treat credential recovery as a tightly controlled workflow requiring explicit legal authorization and documented handling.
Chrome and Edge share a Chromium architecture. Most high-value artifacts are stored in SQLite databases and supporting files under each browser profile. Profiles matter: a single device may contain multiple profiles, each with separate history and cookies.
| File | Primary value | Notes |
|---|---|---|
| History (SQLite) | URLs, visits, timestamps, transitions; downloads tables (schema varies) | Core for chronology; requires correct epoch conversion and timezone handling. |
| Cookies (SQLite) | Cookie domain/path, creation/expiry, access times | Values may be encrypted at rest; interpret session vs persistent cookies correctly. |
| Login Data (SQLite) | Saved credential entries (metadata) | Protected by OS mechanisms; access is legally sensitive and scope-dependent. |
| Web Data (SQLite) | Autofill, saved form data, some tokens/metadata | Useful for attribution and behavioral patterns; avoid over-interpretation. |
| Favicons (SQLite) | Icon cache keyed to sites/pages | Supportive context only; not standalone “proof of visit.” |
| Preferences (JSON-like) | Configuration, extensions references, profile settings | Explains behavior (sync, extensions, proxy settings, policies). |
| Current/Last Session and Current/Last Tabs | Open tabs/window recovery state | Often overwritten; valuable near shutdown if present. |
| Cache, Code Cache, GPUCache | Content remnants and performance caches | High churn and limited retention. |
| Extensions (folder + state) | Installed extensions, IDs, state/config | Often relevant in misconduct allegations (automation, proxy/VPN extensions). |
| Local Storage, IndexedDB, Service Worker | Web app data, session-like artifacts, offline caches | Critical for modern SaaS portals; parsing is contextual and case-specific. |
Edge artifact names are typically the same as Chrome (History, Cookies, Web Data, etc.), but enterprise policy enforcement and managed profiles can affect retention, telemetry, and accessible structures.
For Chromium browsers, “History” is necessary but rarely sufficient. A defensible narrative typically correlates: visit records + download entries + session/tab state + OS corroboration (recent files, link files, execution traces), especially in employee misconduct or timecard disputes.
Broader context: Browser Forensics.
Firefox stores many artifacts in SQLite, but the profile layout and file names differ from Chromium. A critical database is places.sqlite, which houses both history and bookmarks data.
| File | Primary value | Notes |
|---|---|---|
| places.sqlite | History + bookmarks; visit counts; timestamps | Core for chronology. Validate parsing and field definitions by version. |
| cookies.sqlite | Cookie state, expiry, access times | Useful for session inference; not a standalone identity proof. |
| formhistory.sqlite (where present) | Form entry history | Can capture typed values depending on settings, versions, and data retention. |
| sessionstore.jsonlz4 (and backups) | Open tabs/windows recovery state | Potentially valuable near shutdown; volatile/overwrite risk is high. |
| cache2 (structure) | Cached content remnants | Retention can be short; SSD/TRIM reduces recoverability after deletion. |
Safari is primarily a macOS artifact set in modern contexts. Many Safari records are held in Apple-specific database structures and WebKit caches. Safari also interacts with system services that may provide corroboration in some cases.
Apple evolves storage locations and formats by OS version. Accurate interpretation requires identifying macOS and Safari versions, and whether iCloud sync is enabled.
A defensible conclusion states what was found, what could not be found, and why the gap is plausible (private mode, clearing activity, retention, encryption, TRIM, missing logs)—without implying certainty.
Browser timestamps often use different epochs and units than standard Unix time. Incorrect conversion is a common source of error. Examiners also account for time zone, daylight saving transitions, and whether timestamps represent “visit start,” “last access,” or “last modified.”
Because schemas and versions vary, examiners validate conversions by cross-checking known events (e.g., a confirmed meeting time, a download that exists on disk, or OS file timestamps).
Treat every “timestamp” as a field with a definition. When reporting, document: (1) the source artifact, (2) the field name, (3) the conversion method, and (4) the time zone context used for presentation.
Browser forensics is most persuasive when it is part of a multi-source timeline. A typical approach is:
Broader methodology: Internet History Analysis.
Conclusions should be framed carefully: browser activity can support time-based inferences, but it is rarely sufficient alone.
Personal matters require extra care around privacy, scope, and what can be stated with confidence. Examiners typically focus on objective records (sites accessed, timestamps, downloads) and avoid speculation.
