Attackathon | Fuel Network

Fuel is an operating system purpose built for Ethereum Rollups. Fuel allows rollups to solve for PSI (parallelization, state minimized execution, interoperability) without making any sacrifices.

Impacts in Scope

Bugs in the Fuel VM and Compiler are the top priority for Fuel. Whitehats who focus here will earn the greatest rewards and acclaim from Fuel.

Proof of Concept (PoC) Requirements

A PoC, demonstrating the bug's impact, is required for this program and has to comply with the Immunefi PoC Guidelines and 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.

Critical
Unintended permanent chain split requiring hard fork (network partition requiring hard fork)
Critical
Bypassing the bridge timelock
Critical
Permanent freezing of funds on the L1 Bridge side
Critical
Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield
Critical
Direct theft of any user NFTs, whether at-rest or in-motion, other than unclaimed royalties
Critical
Permanent freezing of funds
Critical
Permanent freezing of NFTs
Critical
Unauthorized minting of NFTs
Critical
Predictable or manipulable RNG that results in abuse of the principal or NFT
Critical
Unintended alteration of what the NFT represents (e.g. token URI, payload, artistic content)
Critical
Direct loss of funds
Critical
Execute arbitrary system commands

Program's Out of Scope information

KYC Requirement

Fuel Network will be requesting KYC information in order to pay for successful bug submissions to whitehats who earn $500 USD or more. The following information will be required:

  • Full name
  • Date of birth
  • Proof of address (either a redacted bank statement with address or a recent utility bill)
  • Copy of Passport or other Government issued ID

Eligibility Criteria

Security researchers who wish to participate must adhere to the rules of engagement set forth in this program and cannot be:

  • On OFACs SDN list
  • From a restricted country or territory: North Korea, Iran, Cuba, Syria, certain regions of Ukraine (Crimea, Donetsk and Luhansk), West Bank and Gaza regions of Israel, Venezuela, Afghanistan
  • Official contributor, both past or present
  • Employees and/or individuals closely associated with the project
  • Security auditors that directly or indirectly participated in the audit review, or who work fo the company which did the audit review

Responsible Publication

Whitehats may publish their bug reports after they have been fixed & paid, or closed as invalid, with the following exceptions:

  • Bug reports in mediation may not be published until mediation has concluded and the bug report is resolved.
  • Immunefi may publish bug reports submitted to this Attackathon and a leaderboard of the participants and their earnings.

Immunefi Standard Badge

By adhering to Immunefi’s best practice recommendations, Fuel Network has satisfied the requirements for the Immunefi Standard Badge.

Out of Scope Impacts

  • Impacts on Example Code provided by Fuel Network or smart contract code that was deployed by the user.

All Categories:

  • Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
  • Impacts caused by attacks requiring access to leaked keys/credentials
  • Impacts caused by attacks requiring access to privileged addresses (governance, strategist) except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
  • Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
  • Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
  • Best practice recommendations
  • Feature requests
  • Impacts on test files and configuration files unless stated otherwise in the b

Blockchain/DLT & Smart Contract Specific:

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Impacts requiring basic economic and governance attacks (e.g. 51% attack)
  • Lack of liquidity impacts
  • Impacts from Sybil attacks
  • Impacts involving centralization risks

Websites and Apps:

  • Theoretical impacts without any proof or demonstration
  • Impacts involving attacks requiring physical access to the victim device
  • Impacts involving attacks requiring access to the local network of the victim
  • Reflected plain text injection (e.g. url parameters, path, etc.)
  • This does not exclude reflected HTML injection with or without JavaScript
  • This does not exclude persistent plain text injection
  • Any impacts involving self-XSS
  • Captcha bypass using OCR without impact demonstration
  • CSRF with no state modifying security impact (e.g. logout CSRF)
  • Impacts related to 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
  • Impacts causing only the enumeration or confirmation of the existence of users or tenants
  • Impacts caused by vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
  • Lack of SSL/TLS best practices
  • Impacts that only require DDoS
  • UX and UI impacts that do not materially disrupt use of the platform
  • Impacts primarily caused by browser/plugin defects
  • Leakage of non sensitive API keys (e.g. Etherscan, Infura, Alchemy, etc.)
  • Any vulnerability exploit requiring browser bugs for exploitation (e.g. CSP bypass)
  • SPF/DMARC misconfigured records)
  • Missing HTTP Headers without demonstrated impact
  • Automated scanner reports without demonstrated impact
  • UI/UX best practice recommendations
  • Non-future-proof NFT rendering

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
