Obyte

Obyte is a distributed ledger based on directed acyclic graph (DAG) and is without middlemen. Unlike centralized ledgers and blockchains, access to the Obyte ledger is decentralized, disintermediated, free (as in freedom), equal, and open.

The Obyte Foundation is interested in securing their network, their core library, their GUI wallet, and one of their autonomous agents (smart contract). Primary areas of concern are around loss of user funds, DoS, and total network shutdown.

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

In order to qualify for the reward of USD 50 000, the bug reported must be able to cause unrecoverable total network shutdown of the entire Obyte network or allow the unpermitted execution of transactions from accounts of other users without their private keys. All other critical bug reports are capped at USD 2 500.

Theft of yield/interest in this bug bounty program is considered Low.

All web and app bug reports must come with a PoC. All bug reports submitted without PoC will be rejected with instructions to provide PoC.

Payouts are handled by the Obyte Foundation directly and are denominated in USD. The payout can be completed in GBYTE, BTC, or OUSD.

We are especially interested in receiving and rewarding vulnerabilities of the following types:

Smart Contracts and DAG

• Re-entrancy
• Logic errors
  • including user authentication errors
• Trusting trust/dependency vulnerabilities
  • including composability vulnerabilities
• Oracle failure/manipulation
• Novel governance attacks
• Economic/financial attacks
  • including flash loan attacks
• Congestion and scalability
  • including running out of funds for fees
  • including susceptibility to frontrunning
• Consensus failures
• Cryptography problems
  • Signature malleability
  • Susceptibility to replay attacks
  • Weak randomness
  • Weak encryption
• Susceptibility to timestamp manipulation
• Missing access controls / unprotected internal or debugging interfaces

Websites and Apps

• Remote Code Execution
• Trusting trust/dependency vulnerabilities
• Vertical Privilege Escalation
• XML External Entities Injection
• SQL Injection
• LFI/RFI
• Horizontal Privilege Escalation
• Stored XSS
• Reflective XSS with impact
• CSRF
• CSRF with impact
• Direct object reference
• Internal SSRF
• Session fixation
• Insecure Deserialization
• Direct object reference
• Path Traversal
• DOM XSS
• SSL misconfigurations
• SSL/TLS issues (weak crypto, improper setup)
• URL redirect
• Clickjacking
• Misleading Unicode text (e.g. using right to left override characters)
• Coercing the application to display/return specific text to other users

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 DAG

• 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

Websites and Apps

• Theoretical vulnerabilities without any proof or demonstration
• Content spoofing / Text injection issues
• Self-XSS
• Captcha bypass using OCR
• CSRF with no security impact (logout CSRF, change language, etc.)
• Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
• Server-side information disclosure such as IPs, server names, and most stack traces
• Vulnerabilities used to enumerate or confirm the existence of users or tenants
• Vulnerabilities requiring unlikely user actions
• URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
• Lack of SSL/TLS best practices
• DDoS vulnerabilities
• Attacks requiring privileged access from within the organization
• Requests for new features
• Bugs without proof-of-concept exploits showing impact

The following activities are prohibited by 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
