Key Takeaways
- Telegram cyberattacks use fake channels, impersonation, and malicious downloads.
- Social engineering, not platform flaws, drives most successful attacks.
- Unverified links, bots, and shared files are common entry points.
- Access controls and source verification reduce Telegram security risks.
- Continuous security awareness training helps prevent messaging-based attacks.
According to YouGov Profiles data, 41% of users aged 18-34 are active Telegram users. According to SignHouse research citing Telegram data from November 2022, Telegram reported 700 million monthly active users globally. According to Telegram’s official moderation data, over 14 million groups and channels were blocked by the app in the first half of 2025 alone.
That’s the nutshell version of the Telegram cybersecurity problem.
Attackers use Telegram because it is fast, hard to trace, and nearly anonymous. It is easy to use a bot to carry out multiple actions, such as launching phishing campaigns, harvesting credentials, and deploying malware, without human intervention. According to Kaspersky’s Digital Footprint Intelligence data, the volume of cybercriminal posts surged by 53% in May-June 2024 compared to the same period last year. By 2025, it was one of the world’s most popular locations for sales of data leaks, ransomware, and phishing kits.
Understanding Telegram cybersecurity risks is critical for any organization. Here’s what you need to know.
Types of Telegram Cyber Threats
The following are the various types of Telegram-based cyber threats that are used to harm organizations:
Phishing Attacks
These frauds are used to spread fake messages and emails that appear to come from a trusted source (banking, HR, email, and IT departments). Once achieved, the purpose is to obtain personal data, usernames, passwords, and banking information.
Social Engineering
Using direct messages, attackers coerce employees into wiring money to them, revealing passwords, or downloading malware. Such persuasion can be difficult to spot, and their targets may feel embarrassed.
Malware Distribution
Telegram channels and bots are used to spread ransomware, trojans, and keyloggers. One bad click on a file or a link can compromise an entire device.
Insider Threats
Employees or former employees could leak confidential information to other employees or the public using Telegram. Most internal monitoring tools cannot analyze Telegram traffic, leading to leaks going undetected for weeks.
Data Exfiltration
Stolen data is easily transferred on Telegram. Threat actors can transfer to encrypted channels without triggering a normal alarm.
Botnet Command and Control (C&C)
Commands are issued to infected machines via Telegram botnets, without connecting to any dark web server.
Phishing-as-a-Service (PhaaS) via Telegram Bots
Criminal groups sell subscriptions to phishing kits via private Telegram channels, such as RaccoonO365, which had 845 members as of August 2025. With purchase, users receive bots that scrape credentials and feature fake login pages, no technical skills required. This is one of the fastest-growing cyber scams of 2025.

Real Incidents of Telegram-Based Cyber Attacks
Star Health Insurance Data Breach (2024)
Incident: In 2024, attackers leaked details of more than 31 million Star Health customers through a Telegram chatbot and website. Star Health is a major health insurance provider. The attackers demanded $68,000 in ransom, prompting legal action.
Impact: The breach exposed confidential details, damaged brand reputation, increased the chance of penalties, and highlighted the difficulty of removing harmful content from these platforms.
Key Takeaways: Telegram is becoming a hub for cyber threats. Organizations should monitor messaging apps, improve incident response, and provide security awareness training to employees to reduce risks.
What Telegram Has Done to Address This
Following the detention of CEO Pavel Durov in France in August 2024, Telegram updated its privacy policy and now shares users’ phone numbers and IP addresses with law enforcement agencies upon receipt of a valid court order.
Other changes include:
- End-to-end encryption for Secret Chats
- Two-factor authentication (2FA) for accounts
- Bot verification to guide users to select genuine bots
- Automated spam and malware detection within chats and channels, with blocking activity rising significantly and monthly takedown figures comparable to peak levels seen throughout 2023
- Limits on illegal activity in public channels
- API access control systems to prevent automated abuse
- Regular security audits and bug bounty programs
While a range of illegal activities continues to be hosted on the platform, Telegram’s environment has become noticeably more challenging for sustained underground operations. However, criminal activity has not ceased; rather, it has migrated to new platforms such as Signal and Session, making the overall threat landscape more fragmented.
10 Ways to Protect Your Organization
1. Educate staff about threats specific to Telegram
Most staff don’t recognize that they are vulnerable to targeted attacks on a personal messaging platform. Show them how to detect phishing attacks, malicious login accounts, and social engineering tactics.
2. Establish a clear policy on Telegram use
Restrict or prohibit the use of Telegram for business communication. Hold all company-related conversations over verified, approved channels.
3. Implement 2FA on all work-related accounts
Two-factor authentication will prevent most unauthorized logins even if passwords are compromised.
4. Detect and block malicious bots
Implement mechanisms to detect phishing bots in your organization’s Telegram environment. Identify and block them quickly.
5. Protect all devices with Telegram installed
Implement mobile device management (MDM) policies. Disable Telegram on unmanaged personal devices that may access organizational data.
6. Lock down Telegram privacy settings
Educate employees on how to set their privacy settings to control who can add them to groups and determine how to hide their phone number from unknown sources.
7. Monitor Telegram for data leaks
Your credentials or company data might be known on some Telegram channel. Use threat intelligence applications that analyze Telegram and dark web content and send you notifications immediately.
8. Run social engineering simulations
Just training won’t cut it. Run Telegram phishing simulations (messages from fake accounts impersonating executives) so employees are ready when the real thing hits.
9. Enforce endpoint protection on all devices
Block malware delivered via Telegram files and links. For employees who use Telegram for work, maintain access logs and implement endpoint detection software.
10. Incorporate Telegram into your incident response plan
Most IR plans are built around email. Prepare scenarios for a Telegram data dump or an employee being solicited via DM. Conduct exercises annually.
By following these strategies, organizations can reduce the risk of Telegram cyberattacks and strengthen their overall security posture.
