Telegram, one of the most popular messengers in the world, attracts users with its speed, convenience and declared security. However, despite the reputation of a secure platform, privacy issues in Telegram remain relevant, especially against the backdrop of growing cases of user deanonymization.

In this comprehensive guide, we’ll take a detailed look at the methods and tools used to de-anonymize Telegram users and channels. We’ll analyze how decoy bots work, explore ways to determine user locations, and look at using archives to analyze old data. Our goal is to give you a full understanding of the risks and methods for protecting your privacy on Telegram in 2024.

Privacy in Telegram: Myths and Reality​

Telegram markets itself as a highly secure and private platform, offering features such as secret chats with end-to-end encryption. However, the reality may differ from the advertising claims.

Key facts about privacy in Telegram:​

• Standard Chats: Most Telegram messages are encrypted on the server by default, not end-to-end. This means that Telegram can potentially access the content of these messages.
• Metadata: Telegram collects various metadata, including IP addresses, device information, and username history. This data can be used to track user activity.
• Government requests: In some cases, Telegram may be forced to disclose user data at the request of law enforcement. For example, in 2022, German authorities were granted access to Telegram user data as part of an investigation into extremist activity.
• Live Location: The live location sharing feature may reveal the user's exact coordinates if not used with caution.
• Public channels and groups: Information posted in public channels and groups may be accessible and indexed by search engines, which increases the risk of deanonymization.

Understanding these aspects is essential to using Telegram wisely and protecting your privacy in 2024.

Deanonymization methods in Telegram​

Deanonymization of Telegram users can be done in various ways, from simple analysis of open data to complex technical methods. Let's consider the main approaches:

1. Open Source Intelligence (OSINT)​

• Matching nicknames and profiles across platforms
• Analysis of public messages and comments
• Researching profile photos and other visual materials

2. Technical analysis​

• Using specialized tools for analyzing network traffic (for example, Wireshark)
• Tracking IP addresses and matching them to geographic locations
• Analysis of message and file metadata

3. Social engineering​

• Using honeypot bots to collect data
• Encouraging users to disclose personal information
• Analysis of behavioral patterns in chats and groups

4. Analysis of connections​

• Research contacts and participation in groups/channels
• Analysis of temporal patterns of activity
• Comparing information from different sources to create a user profile

Example of successful deanonymization:
In 2023, a group of researchers was able to identify an anonymous Telegram user who was linked to the spread of disinformation. Using a combination of OSINT and network traffic analysis, they matched his Telegram activity with accounts on other platforms. The key factor was the use of similar phrases and stylistic features in messages on different resources.

Understanding these methods is critical for users who want to protect their anonymity on Telegram. In the following sections, we will look at each of these approaches in detail and offer protection strategies.

OSINT: Open Source Intelligence​

OSINT (Open Source Intelligence) plays a key role in the process of deanonymizing Telegram users. This method is based on the analysis of publicly available information from various sources.

Primary sources of information for OSINT:​

• Social networks: Facebook, Twitter, Instagram, LinkedIn
• Forums and blogs
• Public databases
• News sites and online media
• State registers and public documents

OSINT methods and tools:​

• Search by nickname: Using specialized search engines such as Namechk or UserSearch.org to find accounts with identical or similar nicknames on different platforms.
• Image Analysis: Using reverse image search tools (e.g. Google Images, TinEye) to find other uses of the user's avatar or photos.
• Text data analysis: Using linguistic analysis to find unique phrases or stylistic features in a user's messages.
• Geolocation Analysis: Analyzes photos and metadata to determine the user's probable location.
• Temporal Analysis: Studying the temporal patterns of a user's activity to determine their time zone and daily routine.

An example of using OSINT in deanonymization:
In 2023, a group of investigative journalists used OSINT techniques to identify an anonymous Telegram channel that was distributing political propaganda. The key factor was the discovery of a unique phrase used in the channel description, which also appeared on the personal blog of one of the political activists. Further analysis of the style of the texts and the time patterns of the publications made it possible to establish a connection between the channel and a specific person with a high probability.

OSINT Protection:​

• Use unique nicknames for different platforms
• Avoid posting personal photos publicly.
• Be careful about the information you disclose in public posts.
• Check your digital footprint regularly using search engines
• Use tools to remove personal information from online databases

Understanding OSINT techniques and taking appropriate precautions can significantly reduce the risk of deanonymization on Telegram and other online platforms.

Trap Bots: A Hidden Threat​

Trap bots pose a serious threat to the privacy of Telegram users. These automated programs disguise themselves as useful tools or services, but their true purpose is to collect sensitive data about users.

How trap bots work:​

• Disguise: Bots can pretend to be useful services, such as music search bots, weather forecast bots, or discount bots.
• Data Collection: When interacting with a bot, a user may inadvertently disclose personal information, including: username, IP address, location, contacts from the friend list, message history.
• Behavior analysis: Some bots can analyze a user's communication patterns, linguistic features, and activity time.
• Phishing: Advanced bots can use the collected information to conduct targeted phishing attacks.

Examples of using trap bots:

Case 1: Bot "Musical Assistant"​

In 2023, a bot was discovered that offered users to find information about any song. To do this, they had to send the bot an audio recording. However, in addition to searching for music, the bot collected metadata of audio files, including information about the user's device and location.

Case 2: "Cryptocurrency Advisor"​

Another example is a bot that offered cryptocurrency investment advice. It asked users for information about their crypto wallets, supposedly to provide personalized recommendations. In reality, the bot was collecting users' financial information for subsequent fraudulent activities.

How to protect yourself from trap bots:​

• Check the reputation: Before using a new bot, look for reviews and information about it from reliable sources.
• Limit access: Don't give bots access to your contacts or personal information unless absolutely necessary.
• Use official bots: Give preference to bots created by verified developers or companies.
• Be Skeptical: If a bot asks for too much personal information or offers "too good to be true" deals, it may be a sign of a trap.
• Check regularly: Periodically review the list of bots you interact with and delete any that are unnecessary or suspicious.
• Use two-factor authentication: This is an extra layer of security for your Telegram account.

Understanding how trap bots work and taking precautions can significantly reduce the risk of becoming a victim of fraud or personal data leakage in Telegram.

Geolocation of Telegram users​

Determining the location of Telegram users can be done in a variety of ways, from straightforward methods to more complex technical approaches. Understanding these methods is essential to protecting your privacy on Telegram. Let's look at the main ways to geolocate users and how to protect yourself from them.

Methods for determining the location of Telegram users:​

• Live Location feature: Telegram allows users to share their current location in real time. This feature provides precise coordinates, but only to those to whom the user has chosen to send them.
• IP Analysis: When connecting to Telegram servers, the user's IP address may be logged. IP analysis may provide an approximate geographic location.
• Media metadata: Photos and videos sent via Telegram may contain geotags unless this feature is disabled on the user's device.
• Time Zone Analysis: The time a user is active can indicate their approximate location.
• Cell Tower Triangulation: In some cases, especially for law enforcement requests, it may be possible to determine a location via the cellular network.
• Social Engineering: Bots or malicious users may attempt to trick you into revealing your location through conversation or deception.

Examples of real geolocation cases:​

Case: Location disclosure via bot​

In 2023, a popular Telegram weather bot was found to be collecting and storing user location data. This data was later used for targeted advertising and, in some cases, fell into the hands of criminals.

Case: Determining the location of an activist​

In one high-profile case, law enforcement was able to locate a political activist by analyzing the metadata of photos he posted to a closed Telegram group. Despite using a VPN, the geotags on the photos revealed his real location.

Methods of protection against geolocation in Telegram:​

• Using a VPN: Hides your real IP address, making it difficult to determine your geographic location.
• Disable geotagging: In your device's camera settings, disable the ability to add geotags to photos and videos.
• Caution with Live Location: Use this feature only when absolutely necessary and only with trusted contacts.
• Changing IP regularly: If you use mobile internet, switching between Wi-Fi and cellular data can help change your IP address.
• Using proxy servers: Telegram supports proxy settings, which can help hide your real location.
• Be Vigilant in Communication: Be careful when sharing your location in chats and groups.

Case: Revealing Identity Through Archival Data

In 2023, researchers were able to identify the anonymous creator of a popular Telegram channel using the following approach:

• Analyze current channel content to identify unique phrases and stylistic features.
• Use the Wayback Machine to find archived versions of related websites and social media profiles.
• Discovering an old blog in the archive with a similar writing style and subject matter.
• Analysis of archived post metadata, including publication time and hashtags used.
• Comparing this information with activity on other social networks.

As a result, it was possible to establish a connection between the anonymous Telegram channel and the real identity of the author, who previously ran a public blog on a similar topic.

Methods of protection against analysis of archival data:​

• Regularly audit your online presence: Periodically check what information about you is available in archives. Use tools like the Wayback Machine to view archived versions of pages linked to you.
• Exercising the right to be forgotten: In some jurisdictions, you may be able to request that outdated or irrelevant information about you be removed from search engines and archives.
• Post with caution: Remember that any information posted online may be archived. Avoid posting sensitive or potentially compromising information.
• Using temporary messages: In Telegram and other messengers, use the self-destructing message feature for sensitive information.
• Separate online identities: Don't link your anonymous accounts to your public profiles. Use different screen names and communication styles for different online personas.
• Metadata Control: Remove metadata from files before publishing them, as it may contain identifying information.
• Using data removal tools: There are services that help you automatically delete old posts and comments from social networks.
• Digital Hygiene Education: Increase your awareness of online privacy practices. Stay up-to-date with online safety news and updates.

Using these methods will help minimize the risks associated with analyzing archived data. However, it is important to remember that completely removing a digital trace in the modern world is almost impossible. The most effective strategy is a conscious approach to publishing information about yourself on the Internet and regularly monitoring your online presence.

Deanonymization using stickers​

Telegram stickers, seemingly harmless elements of communication at first glance, can become an unexpected source of information for deanonymizing users. This method, although less obvious than others, can be surprisingly effective in certain situations.

How stickers can reveal a user's identity:​

• Unique Sticker Packs: Some users create or use rare, personalized sticker packs. These stickers may contain unique elements related to specific groups or interests.
• Usage Patterns: The frequency and context of use of certain stickers can create a user's unique "handwriting".
