Rewards by Threat Level

Blockchain/DLT
Critical
Up to $10,000
High
Up to $5,000
Medium
Up to $2,000
Low
Up to $500

Bounties are paid out after a risk assessment (OWASP risk rating methodology) has been made by the Neo DAU team. There are four rates of severity, Critical, High, Medium, Low. All rewards will be paid in the equivalent amount of NEO. Roughly speaking, we calculate the severity of an issue with the following formula:

Severity = Impact * Likelihood Base bounty amounts related to severity are as follows:

Vulnerability SeverityBountyExample
CriticalUp to $10,000Issues leading to severe asset loss
HighUp to $5,000Issues leading to total networks failure
MediumUp to $2,000Single node failure
LowUp to $500Other valid issues

To be eligible for a reward, bug bounty hunters must never attempt to access anyone else's data and do not engage in any activity that would be disruptive or damaging to the Neo production network and testing network, you can investigate with your own built private chain on a private network. The full rules of the bug bounty program can be found further below, which need to be followed.

All bug reports must include the following in the report:

  • Asset - What software asset the vulnerability is related to (e.g. Neo core software/products)
  • Severity - Your opinion on the severity of the issue (e.g. high, moderate, low)
  • Summary - Add a summary of the vulnerability
  • Description - Any additional details about this vulnerability
  • Steps - Steps to reproduce, getting Neo staff or technical team clearly informed of every detailed step.
  • Supporting Material/References - Source code to replicate, list any additional material (e.g. screenshots, logs, etc.)
  • Impact - What security impact could an attacker achieve?
  • Your name and country.

Neo may require more KYC information to be submitted over the Immunefi bug reporting dashboard at its discretion.

Payouts are handled by the Neo team directly and are denominated in USD. However, payouts are done in NEO.

Program Overview

Neo is a distributed network which utilizes blockchain technology and digital identity to digitize assets and automate the management of digital assets using smart contracts. Neo network has two tokens, NEO representing the right to manage Neo blockchain and GAS representing the right to use the Neo Blockchain.

The purpose of the Neo vulnerability bounty program is to be proactive about blockchain security by providing a channel for security researchers to report potential security vulnerabilities identified related to our underlying infrastructure. Everyone who finds the vulnerabilities can submit a bug report through Immunefi. Neo will try their best to investigate those eligible vulnerabilities and fix the valid issues. All rewards will be paid in the equivalent amount of NEO.

Note: Higher rewards will be paid out in case of vulnerabilities of certain interest and criticality. Before reporting any issues, please check the following disclosures on responsibilities, program rules, and reporting manner notice.

For more information about Neo, please visit https://neo.org/.

This bug bounty program has a different reward timeline than other bug bounty programs on Immunefi, though the 48 hours for acknowledgement is observed. Please check the “Program Rules and Response Terms” section for more information.

KYC required

The submission of KYC information is a requirement for payout processing.

Prohibited Activities

Default prohibited activities
  • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
  • 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 that are executed against project assets
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
  • Any other actions prohibited by the Immunefi Rules

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity. Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
