Telegram expert report: channels, groups and ephemeral messages

Forensic examination of secret chats, channels and groups, with authorship and traceability analysis.

Telegram poses challenges that WhatsApp does not: secret chats with end-to-end encryption, self-destructing messages, channels with thousands of members and users with no visible phone number. The expert report documents what is technically verifiable (content, dates, user and channel identifiers) and rigorously explains to the judge what can and cannot be affirmed.

Frequently asked questions

How long does the report take?
The complete process takes between 5 and 7 business days. In urgent cases, we can expedite delivery with a surcharge.
Can you analyze Telegram secret chats?+
Yes, we have the technical capability to extract and analyze secret chats as long as we have access to the device before they are deleted. Secret chats are not synced to the cloud.
Is the report legally valid?+
Yes, all our reports have full court validity. Our digital forensic experts can ratify the report in court if necessary.
Do I need to bring my device?+
For optimal forensic extraction, especially of secret chats, direct device access is recommended. We can also work with Telegram Desktop exports in some cases.
Can deleted messages be recovered?+
It depends on several factors: chat type, time elapsed, and device. Regular synced chats have more recovery possibilities than deleted secret chats.
What is the difference from WhatsApp analysis?+
Telegram has special features such as secret chats with self-destruction, larger file capacity, and different data structure that require specific forensic techniques.
Does it work with all devices?+
Yes, we work with iPhone, Android, Windows, Mac, and Linux. The methodology varies by platform but we guarantee forensic validity in all cases.
How much does the service cost?+
The price depends on complexity, data volume, and chat type. Contact us for a personalized no-obligation quote.
Can the expert testify in court?+
Yes, our forensic experts are prepared to ratify the report in court, appear before the tribunal, and answer questions from the procedural parties. Their technical experience and certifications guarantee credibility before any judge or magistrate.
What happens if the other party denies the authenticity of the messages?+
That is precisely why a forensic report is needed. The forensic analysis includes metadata verification, cryptographic hashes, analysis of the underlying database, and other technical elements that scientifically demonstrate authenticity, beyond simple screenshots that can be easily manipulated.
Can the analysis be done if I don't have access to the phone?+
It depends on the case. If you have Telegram Desktop exports or cloud backups, we can work with that data. However, for secret chats or deeper forensic analysis, direct device access is required. We advise you on the best option according to your situation.
Can I use the report in criminal and civil proceedings?+
Yes, Telegram conversation forensic reports are valid in both criminal proceedings (complaints for threats, fraud, slander) and civil proceedings (divorces, commercial disputes, contractual breaches). Forensic rigor guarantees its admissibility in any jurisdiction.
What about voice messages and video calls?+
Voice messages that have been sent as audio files can be extracted and analyzed, including their metadata. Real-time Telegram video calls are not automatically recorded by the application for privacy reasons, so they cannot be subject to forensic analysis unless they have been recorded by the user through other means.
What technical information does the forensic report include?+
The report includes: analysis of Telegram's SQLite database, metadata extraction (dates, times, delivery/read status), integrity verification through SHA-256 hashes, identification of participating users, analysis of shared multimedia files, complete chain of custody, technical conclusions, and annexes with forensic captures. All documented according to international computer forensics standards.
How much content can I include in the analysis?+
There is no technical limit. We can analyze from short conversations with few messages to extensive histories with thousands of messages, large groups, multiple chats, or complete channels. Price and delivery time adjust according to the volume of data to process. We provide you with a clear quote before starting the work.
Can a Telegram secret chat be examined by an expert?+
Only on the device where it resides: secret chats use end-to-end encryption and are not synced to the cloud. If the message had a timer and has already self-destructed, there is nothing left to recover, which is why acting quickly is critical.
Can you identify who is behind an anonymous channel?+
We can document the channel's and its administrators' numeric identifiers, username history and forwarding patterns. Identifying the account holder's civil identity requires a judicial request to the platform: the report lays the technical groundwork for that request.
How does this differ from a WhatsApp expert report?+
Telegram adds mass channels, public groups, accounts without a visible phone number, and ephemeral messages. The analysis focuses more on authorship, forwarding traceability and channel structure than on the device's local database.
If I leave the group, do I lose the evidence?+
In many cases, yes: leaving a group means losing access to the history. Do not leave until the evidence has been secured.
Does the report distinguish proven facts from circumstantial evidence?+
Always, and it is one of its main strengths before a judge. Claiming more than the technique allows is the fastest way for the opposing party to dismantle the entire report.
Do documents signed online have the same validity as those signed in person?+
Exactly the same. Law 11/2023 recognises the full legal validity of notarial documents executed by video call with a qualified electronic signature before a registered notary.
Do I need a digital certificate?+
Yes, to sign electronically you need a digital certificate or an electronic DNI. If you do not have one, we help you obtain it quickly before your appointment, with no additional handling fee.
Can I do it from abroad?+
Yes, the notarial video call works from any country. You only need a stable connection, your valid identity document and a digital certificate.
How much does this service cost?+
The quote includes the official notarial fees set by the Notarial Association plus our handling, fixed before you start and with no hidden costs. Request it with no obligation via WhatsApp or the form.
What if I have questions during the process?+
Our team supports you from start to finish via WhatsApp, phone or email, and the notary answers all your legal questions before signing.
