Focus Area

IN-SCOPE VULNERABILITIES (Telegram BOT)

We are interested in the following vulnerabilities:

Business logic issues
Payments manipulation
Remote code execution (RCE)
Injection vulnerabilities (SQL, XXE)
File inclusions (Local & Remote)
Access Control Issues (IDOR, Privilege Escalation, etc)
Leakage of sensitive information
Server-Side Request Forgery (SSRF)
Directory traversal
Other vulnerability with a clear potential loss

OUT OF SCOPE

Vulnerabilities found in out of scope resources are unlikely to be rewarded unless they present a serious business risk (at our sole discretion). In general, the following vulnerabilities do not correspond to the severity threshold:

Vulnerabilities in Telegram applications
Assets that do not belong to the company
Best practices concerns
Recently (less than 30 days) disclosed 0day vulnerabilities
Vulnerabilities affecting users of outdated browsers or platforms
Social engineering, phishing, physical, or other fraud activities
Reports that generated by scanners or any automated or active exploit tools
Vulnerabilities involving active content such as web browser add-ons
Most brute-forcing issues without clear impact
Denial of service (DoS/DDoS)
Theoretical issues
Moderately Sensitive Information Disclosure
Spam (sms, email, etc)
MitM and local attacks
Attacks requiring physical access to a user's device
Vulnerabilities that require root/jailbreak
Vulnerabilities requiring extensive user interaction

Program Rules

*Hackers must ensure the application meets the specified criteria before starting testing

Disclosure Guidelines

Do not discuss this program or any vulnerabilities (even resolved ones) outside of the program without express consent from the organization
No vulnerability disclosure, including partial is allowed for the moment.
Please do NOT publish/discuss bugs

Eligibility and Coordinated Disclosure

Reports for applications must include:

Confirmation of on-chain interaction.
Blockchain interaction logs (e.g., transaction hashes, smart contract IDs, or interaction with TON APIs).

Criteria for Applications under the Bug Bounty Program

In Scope

At least one of the following must be met

On-Chain Interaction via TON Blockchain

The application performs transactions recorded on the TON Blockchain (e.g., payments for goods, participation in DAO, interaction with NFTs, or any smart contracts on TON).
The application uses smart contracts to execute application logic.

Integration with TON Ecosystem

The application utilizes mechanics directly tied to TON (e.g., token airdrops with verified smart contract logic, TON DNS, TON Storage, or other similar tools).
The application provides functionality exclusively accessible through TON Wallet (e.g., using TON Connect for authorization and operations related to TON).

Interaction with TON Wallet

The application must include functionality beyond simple authorization via TON Connect.
Users can perform actions requiring transaction signatures via TON Wallet.
TON Wallet usage is verified for business-critical operations (e.g., payments, subscriptions, asset withdrawals/deposits).

Out of Scope

Applications using only TON Connect for login without additional TON Blockchain mechanics.
Airdrops without actual on-chain interaction or verified smart contracts.
Applications that claim future TON integration but lack it in the current version.
Applications operating exclusively on testnet instead of mainnet.
