### What does Telemetry do?

Telemetry is essentially a search engine built specifically for public Telegram content that indexes public Telegram channels, groups, and messages. It helps investigators discover content that may not appear in traditional search engines, making it useful for monitoring communities, tracking narratives, identifying extremist or criminal ecosystems, and locating archived Telegram discussions.&#x20;

**The lowdown:** Unlike Google or traditional search engines, Telemetry focuses specifically on Telegram content that would otherwise be difficult to locate or monitor.

### How to Use:

**1. Search using keywords, phrases, usernames, hashtags, or other relevant identifiers. Broad searches can help identify communities quickly.**

**2. Analyse channels and message patterns. Telegram ecosystems are highly interconnected. One useful channel often leads to many more.**&#x20;

### Cost

* [ ] Free
* [x] Partially Free
* [ ] Paid

Telemetry offers limited free functionality (15 credits), with additional features available through paid access tiers.

## Data Processing

### Account Required:

* [x] Yes
* [ ] No

### Cookies:&#x20;

Telemetry uses an authentication token cookie to manage logged-in user sessions and account identity, alongside a userPlan cookie likely used to track subscription or feature access levels.&#x20;

### Use in Reporting

Telemetry can strengthen investigations involving online communities and information operations.

Useful reporting applications include:

* Documenting extremist messaging.
* Identifying coordinated campaigns.
* Tracing repost networks.
* Analysing narrative spread.
* Identifying public recruitment efforts.
* Mapping influence ecosystems.

Modern Telegram OSINT guides describe Telemetry as part of the standard toolkit for investigators tracing criminal networks on Telegram, disinformation ecosystems, fraud and cybercrime groups and coordinated influence campaigns.

**Note:** Telegram content can disappear rapidly due to deletions, bans, account removals and migration to new channels so preservation is crucial.

### Summary

Telemetry can provide valuable visibility into one of the internet’s most difficult-to-search platforms, sitting mainly in the deep reconnaissance, collection, and analysis phases of the OSINT workflow, specifically for Telegram ecosystem discovery.

### Ownership

Not publicly disclosed.

### Ethical Considerations

* Respect privacy boundaries and protect sensitive investigative data.
* Avoid unnecessary collection of personal information.
* Understand local surveillance and evidence laws.
* Recognise that Telegram usernames can change, public content does not confirm identity, and impersonation is common.
* Always validate findings using multiple independent sources where possible.
