Hathor is a digital platform for financial transactions and contracts with a unique combination of high scalability and high decentralization. It creates the perfect environment for multiple use cases where scale, efficiency, long-term security, and censorship-resistance through network distribution combined are needed or can drastically cut current costs and bureaucracy.

Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.
All Blockchain/DLT and Web/App bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required. Bug reports are required to include a runnable PoC in order to prove impact. Exceptions may be made in cases where the vulnerability is objectively evident from simply mentioning the vulnerability and where it exists. However, the bug reporter may be required to provide a PoC at any point in time.
Hathor Labs requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed is a government ID and proof of address.
Unlike other bug bounty programs on Immunefi, all bug report submissions, including associated vulnerabilities, become the exclusive property of Hathor Labs. By making a submission to this program and in consideration for a bounty, the bug submitter conveys all ownership rights, titles, and interests in the bug report to Hathor Labs. Thus, the final decision on whether a postmortem will be written is at the sole discretion of Hathor Labs.
Payouts are handled by the Hathor Labs team directly and are denominated in USD. However, payouts are done in HTR.

Only the latest release is in scope for Blockchain/DLT and Web/App assets. You can access the latest release for a repository by adding "releases/latest" to the end of a repository's URL.
Never run tests on Hathor's production environments such as the mainnet. If you believe your attack would only work in our production environment, get in touch with us at [email protected].
All config and test files are considered as out-of-scope of this bug bounty program.
Hathor-core/hathor/wallet is out-of-scope. https://github.com/HathorNetwork/hathor-core/tree/master/hathor/wallet
All code of Hathor Network can be found at https://github.com/HathorNetwork. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Impacts in scope
Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.
- Network not being able to confirm new transactions (Total network shutdown)CriticalImpact
- Unintended permanent chain split requiring hard fork (Network partition requiring hard fork)CriticalImpact
- Direct loss of fundsCriticalImpact
- Permanent freezing of funds (fix requires hardfork)CriticalImpact
- Creation of tokens, including HTR, without following blockchain and consensus rulesCriticalImpact
- Unintended chain split (Network partition)HighImpact
- Transient consensus failuresHighImpact
- High compute consumption by validator/mining nodesMediumImpact
- Attacks against thin clientsMediumImpact
- DoS of greater than 30% of validator or miner nodes and does not shut down the networkMediumImpact
- DoS of greater than 10% but less than 30% of validator or miner nodes and does not shut down the networkLowImpact
Websites and Applications
- Execute arbitrary system commandsCriticalImpact
- Direct theft of user fundsCriticalImpact
- Malicious interactions with an already-connected wallet such as modifying transaction arguments or parameters, substituting contract addresses, and submitting malicious transactionsCriticalImpact
- Direct theft of user NFTsCriticalImpact
- Changing details of other users (including modifying browser local storage) without already-connected wallet interaction and with significant user interaction such as iframing leading to modifying the backend/browser state (demonstrate impact with PoC)LowImpact
Out of Scope & Rules
The following vulnerabilities are excluded from the rewards for this bug bounty program:
- Attacks that the reporter has already exploited themselves, leading to damage
- Attacks requiring access to leaked keys/credentials
- Attacks requiring access to privileged addresses (governance, strategist)
Smart Contracts and Blockchain
- Incorrect data supplied by third party oracles
- Not to exclude oracle manipulation/flash loan attacks
- Basic economic governance attacks (e.g. 51% attack)
- Lack of liquidity
- Best practice critiques
- Sybil attacks
- Centralization risks
Websites and Apps
- Theoretical vulnerabilities without any proof or demonstration
- Attacks requiring physical access to the victim device
- Attacks requiring access to the local network of the victim
- Reflected plain text injection ex: url parameters, path, etc.
- This does not exclude persistent plain text injection
- Captcha bypass using OCR without impact demonstration
- CSRF with no state modifying security impact (ex: logout CSRF)
- Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”) without demonstration of impact
- Server-side non-confidential information disclosure such as IPs, server names, and most stack traces
- Vulnerabilities used only to enumerate or confirm the existence of users or tenants
- Vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
- Lack of SSL/TLS best practices
- DDoS vulnerabilities
- Feature requests
- Issues related to the frontend without concrete impact and PoC
- Best practices issues without concrete impact and PoC
- Vulnerabilities primarily caused by browser/plugin defects
- Leakage of non sensitive api keys ex: etherscan, Infura, Alchemy, etc.
- Any vulnerability exploit requiring browser bugs for exploitation. ex: CSP bypass
- Automated Scanner Reports without demonstrated impact
- UI/UX best practices recommendations
- Non-future-proof NFT rendering
The following activities are prohibited by this bug bounty program:
Any testing with mainnet or public testnet contracts; all testing should be done on private testnets Any testing with pricing oracles or third party smart contracts Attempting phishing or other social engineering attacks against our employees and/or customers Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks) Any denial of service attacks Automated testing of services that generates significant amounts of traffic Public disclosure of an unpatched vulnerability in an embargoed bounty
