Can Hackers Steal Telegram Data? A Look Into Telegram’s Security Risks
Posted: Thu May 29, 2025 7:11 am
Telegram is widely regarded as a secure messaging app, known for its speed, features, and privacy-oriented design. However, as with any online platform, users often ask: Can hackers steal Telegram data? While Telegram has implemented multiple layers of security, it is not completely immune to threats. Understanding how Telegram works and what vulnerabilities exist is crucial for anyone concerned about data privacy and protection.
How Telegram Handles Security
Telegram uses a combination of cloud-based storage and telegram data encryption to protect user data. Regular chats on Telegram are encrypted between the user's device and Telegram’s servers using MTProto, the platform’s custom encryption protocol. This allows messages to be stored in the cloud and accessed from multiple devices. However, only Telegram has the keys to decrypt these messages, not the users themselves.
For more secure communication, Telegram offers Secret Chats, which use end-to-end encryption (E2EE). In Secret Chats, only the sender and receiver can read the messages, and not even Telegram has access. These chats also support self-destruct timers and disable message forwarding, adding extra layers of security.
Potential Security Vulnerabilities
While Telegram’s encryption methods are strong, no system is perfectly secure. There are several ways hackers might try to access Telegram data:
Device Compromise: If a hacker gains access to a user's phone or computer through malware, they can potentially access Telegram messages and media stored on the device. This is especially risky if the hacker installs keyloggers or remote access tools.
Phishing Attacks: Hackers can trick users into revealing their Telegram login codes or credentials through fake websites or messages. Since Telegram uses SMS-based authentication, intercepting this code or stealing a session token can grant a hacker access.
Weak Account Protection: Telegram offers two-step verification, allowing users to set a password in addition to the SMS code. Without this feature enabled, accounts are easier to hijack. Users who don’t set strong passwords or fail to enable this option are at greater risk.
Cloud Chats Are Not End-to-End Encrypted: Unlike Secret Chats, Telegram’s default chats are stored in the cloud. While they are encrypted during transit and at rest, Telegram itself holds the keys. In the event of a server breach or a legal demand from authorities, this data could be exposed or handed over.
Notable Incidents
Over the years, Telegram has been targeted in various cyberattacks. For example, in 2019, hackers reportedly exploited a vulnerability in Telegram's desktop app to install malware. There have also been cases where government-linked attackers targeted Telegram users through phishing or SIM-swap attacks, particularly in regions with political unrest.
Protecting Your Telegram Data
To minimize the risk of hacking:
Enable two-step verification.
Use Secret Chats for sensitive conversations.
Avoid clicking suspicious links or downloading unknown files.
Regularly update the Telegram app for security patches.
Be cautious with public or group chats that may expose your username.
Conclusion
While Telegram offers robust security features, it is not entirely hacker-proof. The risk of data theft increases with poor user habits or compromised devices. By understanding how Telegram works and taking steps to protect your account, users can greatly reduce the likelihood of their data being stolen.
