What to Do If Your Telegram Account Is Hacked: How to Fix It and Prevent It in the Future

At the beginning of 2025, Telegram surpassed 1 billion users. And with it came a billion reasons for cybercriminals to blur the line between your phone and their wallets.
Your messenger holds chats, contacts, access to banking data, documents, business negotiations. Sometimes even control over Telegram bots and channels with thousands of subscribers. When that digital territory suddenly falls into the wrong hands, it’s a moment you wish you could freeze. But you can’t. You need to act.

A reliable anti-detect browser is not just a tool — it’s a shield in a world where digital security has become an illusion for many. Data leaks and account breaches are a reality across nearly every platform, especially when it comes to multi-accounting and gray traffic. Most browsers promise protection, but few deliver.

MoreLogin stands out — both in action and philosophy.
It doesn’t create illusions or hide weaknesses — because there are none. Strict profile isolation, transparent architecture, and most importantly — uncompromising confidentiality. Where others fall under bans and leaks, MoreLogin stays standing.

If you work with sensitive data, accounts, advertising, or traffic — it’s time to move from “seems protected” to “absolute control.”
MoreLogin — when you need not just anti-detect, but a guarantee that your business lives under your key, not in some leak archive.

How Telegram Accounts Get Hacked in 2025

Hackers no longer “break” doors — they pretend to be the ones guarding them. Attack methods have grown more sophisticated, and the number of stolen accounts is alarmingly high: in Q1 of 2025 alone, Russian-speaking hacker groups stole over 887,000 Telegram profiles worldwide.

Here’s how it usually happens:

• You receive a message from “Telegram administration” asking you to click a link or send a code. It sounds convincing. But it’s not Telegram — it’s fraudsters impersonating it.

• You’re invited to join an “exclusive offer” — a free Telegram Premium subscription. Inside is a QR code that leads to a fake page. You enter your data — and lose your account.

• On Android, a “new version of Telegram” suddenly appears — offering features that even Telegram itself doesn’t know about. You download the .apk, and with it comes a trojan that steals everything.

• Your smartphone is left unattended — someone issues a duplicate SIM card, gaining access to your SMS codes, accounts, and messages. You’re no longer the owner of your number.

• A Telegram bot or channel you no longer manage gets taken over. Spam, ads, extortion — all under your name. And you don’t even know it.

Telegram is strengthening security, but attackers still find loopholes — especially when the user is too trusting.

Signs That Your Account Has Been Hacked

If hacking came with an alarm, things would be easier. But in reality, it’s silent and stealthy. Watch for these red flags:

• You’re logged out of Telegram for no reason. The system “authorized” someone else.

• New chats appear that you didn’t create. Or old ones disappear.

• Your avatar changes by itself. Your bio now contains strange links or messages asking for help.

• You receive login SMS codes — even though you didn’t try to log in.

• Friends message you: “What’s that link you sent?” or “Did you ask for money?”

• The list of active sessions shows cities you’ve never visited.

If any one of these points matches — start taking action immediately. It only gets worse from here.

In the first 24 hours after your account is compromised, your actions determine the fate of your data. Telegram allows for quick damage control — but the timer is working for both you and the attacker.

Step-by-step recovery process:

1. Log in to Telegram on any device where you still have access.

2. Go to Settings → Devices → Active Sessions. End all sessions that look suspicious: unknown cities, browsers, platforms.

3. Go to Privacy → Two-Step Verification. Enable two-factor authentication. Create a strong, unique password. Link your email.

4. Check your profile settings. Make sure your username, photo, and bio are unchanged.

5. Warn your contacts. Informally: “I was hacked, don’t click anything from me.” Especially if you own public channels — your responsibility is higher.

If more time has passed — recovery becomes harder. Telegram usually alerts the hacker when you try to recover the account. So act fast:

• Open Telegram, enter your phone number.

• Request login via SMS code.

• Enter your two-factor password, if enabled.

• End all other sessions immediately.

If you can’t recover access:

• Contact Telegram support:

  • In-app: Settings → Ask a Question

  • Online: telegram.org/support
    Support is handled by volunteers — response time may vary, but there is a chance.

Sometimes, the only option is to delete your account and start over:

• Go to Settings → Privacy → Delete My Account → Delete Now

• Register again with the same number — if you still control the SIM card.

If your phone is lost — block the SIM immediately via your mobile carrier. Request a replacement and recover your Telegram access after that.

How to Protect Yourself From Future Hacks

The best protection is the one built into your habits. Telegram allows you to close almost every vulnerability — if you spend 15 minutes now:

• Set a PIN code for the app: Telegram → Privacy & Security → Passcode Lock

• Enable device screen lock — set it to 1 or 5 minutes.

• Use Face ID or fingerprint authentication.

• Two-factor authentication is a must. Without it, Telegram is too vulnerable.

Adjust your privacy settings:

• No one should see your number, profile photo, or last seen.

• Only contacts should be able to call you or find you by number.

• Disable group invitations without your approval.

And finally — check active sessions weekly. Telegram shows all devices where you’re logged in. See anything suspicious? Remove it.

Extra Protection for Those Handling Sensitive Data

If you deal with sensitive information — in business, journalism, or politics — consider using:

• A virtual number for Telegram login

• A VPN to hide your IP address

• Password managers: Bitwarden, 1Password, NordPass

• Antivirus software: Kaspersky, Malwarebytes, ESET — scan your system regularly

• Never click on countdown timers or “gifts” in messages. Even if the sender is familiar — they might be hacked too.

In Conclusion: It’s Okay to Be Suspicious

In 2025, being trusting is dangerous. Telegram is now a tool for communication, work, even investments. So treat every notification, link, and new feature with a healthy dose of paranoia — that’s called being smart.

If your account is hacked — don’t panic. Telegram gives you tools. You now have the knowledge. The key is not to delay.

And yes, share this article with anyone who still says: “Why would I care? I only have chats in there…”
You never know what data you’ve stored — until someone else has it.
