If you watch the news, Telegram is a massive contradiction. In one headline, it is praised as a secure lifeline for activists and journalists living under oppressive regimes. In the next headline, it is condemned as a haven for scammers, data brokers, and cybercriminals.
So, what exactly is Telegram used for, and more importantly, is the app actually safe for everyday users?
The answer is complicated. Unlike WhatsApp or iMessage, Telegram is not just a texting app-it is a massive, decentralized social network. Here is an investigator’s breakdown of how Telegram works, why it is so controversial, and what you need to know about its security.
What is Telegram Used For? (The Two Sides)
At its core, Telegram is a cloud-based instant messaging application. However, its features go far beyond sending texts to your friends. It is primarily used for two distinct purposes.
1. The Good: Massive Public Broadcasting
Telegram’s most popular feature is its “Channels.” Unlike a group chat, a Channel allows a single creator to broadcast messages to an unlimited number of subscribers.
- News & Activism: In countries where governments control traditional media and censor platforms like Facebook, activists use Telegram Channels to coordinate protests and distribute independent news.
- Community Building: It is heavily used by cryptocurrency enthusiasts, OSINT researchers, and tech communities to share real-time updates without algorithm interference.
2. The Bad: The “Surface Dark Web”
Because Telegram offers massive group limits (up to 200,000 members per group), allows file sharing up to 2GB, and historically has had very loose content moderation, it has become a hotbed for illicit activity.
As we discussed in our guide on Telegram OSINT investigations, criminals have largely migrated away from traditional dark web forums. Today, threat actors use Telegram groups to sell stolen credit cards, trade leaked passwords, and distribute malware because it is simply easier to use than the Tor network.
Is Telegram Safe? (The Encryption Myth)
The biggest misconception about Telegram is that it is inherently private. Many users download it thinking it is a “secret” app like Signal. This is false.
Cloud Chats vs. Secret Chats
By default, Telegram chats are not end-to-end encrypted.
When you open the app and message a friend, you are using a “Cloud Chat.” That means your message is sent to Telegram’s servers, stored there, and then pushed to your friend. Telegram holds the decryption keys. If their servers are breached, or if a government successfully issues a subpoena, your default messages can be read.
If you want true privacy, you must manually start a “Secret Chat.” Secret Chats use true device-to-device end-to-end encryption. The keys are stored only on your phone and your friend’s phone. Even Telegram’s own engineers cannot read these messages. Furthermore, Secret Chats allow you to set self-destruct timers so messages automatically delete after being read-a feature heavily utilized by privacy advocates and Tails OS users.
How to Stay Safe on Telegram
If you want to use the app for its excellent features without compromising your security, you need to adjust a few default settings:
- Hide Your Phone Number: By default, anyone in a group with you might be able to see your phone number. Go to Settings > Privacy and Security > Phone Number and set “Who can see my phone number” to Nobody.
- Use Secret Chats: If you are sending passwords, sensitive documents, or private information, always manually initiate a “Secret Chat.”
- Beware of Scams: Because criminals use the platform, be incredibly wary of unsolicited messages offering cryptocurrency investments, technical support, or “leaked data.”
The Bottom Line
Telegram is an incredibly powerful tool. It is excellent for following independent news channels and communicating with large communities. However, it is not a magic bullet for privacy. Treat default Telegram chats like normal emails, and always use the manual “Secret Chat” feature when absolute security is required.
Frequently Asked Questions (FAQs)
Is Telegram safer than WhatsApp?
It depends on how you use it. WhatsApp uses end-to-end encryption by default for all chats, meaning nobody (not even WhatsApp) can read your messages. Telegram only uses end-to-end encryption if you manually select the “Secret Chat” feature. However, Telegram collects far less metadata than WhatsApp, which is owned by Meta (Facebook).
Can you be tracked on Telegram?
Yes, if you do not adjust your privacy settings. If your phone number is public, OSINT investigators and scammers can link your Telegram account to your real-world identity. Additionally, if you use the “People Nearby” feature, your physical location can be triangulated by other users.
Why do scammers use Telegram?
Scammers and cybercriminals use Telegram because the app allows them to create massive, easily accessible groups, share large files (like stolen databases), and utilize automated bots to run scams. Furthermore, the platform’s historically lenient moderation policies have made it easier for illicit communities to operate openly.
