CertiK Discovers a High-Risk Vulnerability on Telegram: An In-Depth Analysis
On March 29, 2023, the leading blockchain security firm, CertiK, announced that it had discovered a high-risk vulnerability in Telegram’s Open Network (TON) blockchain. This revelation came as a shock to the crypto community, given Telegram’s reputation for security and its large user base of over 500 million active users. In this in-depth analysis, we will explore the details of this vulnerability and its potential implications.
Background: Telegram’s TON Blockchain
Telegram, the popular messaging app, launched its own blockchain project called TON (The Open Network) in 2019. The TON blockchain aims to provide fast, scalable, and secure transactions for decentralized applications (dApps) built on its platform. The network uses a unique consensus mechanism called “Proof-of-Stake,” which sets it apart from other well-known blockchain networks like Bitcoin and Ethereum, that use the “Proof-of-Work” mechanism.
The Discovered Vulnerability
CertiK, a leading blockchain security firm, identified a critical bug in the TON blockchain’s smart contracts, specifically in the “TON-Staking” smart contract. The vulnerability could potentially allow an attacker to drain the entire staked token supply in seconds, causing significant financial losses for legitimate users.
Implications and Mitigation
The discovery of this vulnerability led to concerns about the security of Telegram’s TON blockchain and raised questions about how such a bug could go unnoticed for so long. However, it is essential to note that CertiK reported the vulnerability to Telegram as soon as they discovered it, allowing the platform to take appropriate measures to mitigate the risk. The vulnerability was patched, and staking was temporarily suspended on the TON network.
Lessons Learned
This incident serves as a reminder that no system is immune to vulnerabilities and the importance of rigorous security testing. It also highlights the crucial role that ethical hackers like CertiK play in identifying and reporting vulnerabilities to ensure the safety and trustworthiness of blockchain networks. This incident could potentially lead to more stringent security measures within the crypto community, making the ecosystem safer for all users.
Stay Informed and Secure

The decentralized nature of Telegram allows for secure, instant messaging and file sharing among users, fostering collaboration and engagement within the blockchain community.
Moreover, Telegram has been instrumental in facilitating the growth of
Initial Coin Offerings (ICOs)
and decentralized finance (DeFi) projects. Many of these initiatives have used Telegram to communicate with their investors, build communities, and launch their tokens. This close relationship between decentralized projects and Telegram highlights the platform’s significant role in driving innovation and adoption within the blockchain ecosystem.
Background: Understanding Telegram and Its Security Measures
Telegram is a popular messaging platform that has gained significant attention, particularly within the cryptocurrency communities. Its unique features make it an ideal choice for users looking for a secure and efficient way to communicate and share information.
Description of Telegram as a popular messaging platform for cryptocurrency communities
Telegram‘s private and public channels allow users to create or join groups of any size, making it easier for individuals with similar interests to connect. These channels are essential for cryptocurrency communities, as they facilitate real-time discussions, announcements, and trading activities. Moreover, Telegram offers an extensive range of bots and integrations, which enable automated tasks such as setting alerts for price changes or managing digital wallets.
Overview of Telegram’s security features
Two-factor authentication (2FA)
One of the most significant security measures that Telegram offers is two-factor authentication (2FA). By enabling 2FA, users add an extra layer of protection to their accounts, requiring a unique code sent through SMS or an authenticator app alongside the regular password. This additional step significantly reduces the risk of account hijacking.
Encrypted messaging
Encrypted messaging
Another security feature that Telegram provides is encrypted messaging. The platform offers end-to-end encryption, ensuring that the content of messages and media sent between users remains private. This encryption is particularly important for cryptocurrency communities discussing sensitive financial information.
Limited API access control
Limited API access control
Lastly, Telegram’s limited API access control is a crucial feature that helps protect the platform from potential security threats. This control ensures that bots and third-party apps have limited access to user data, reducing the risk of unwarranted information leaks.
