Cryptokek

Cryptokek is a cryptocurrency analytics toolbox that provides unique data insights about cryptocurrencies. The focus of the Cryptokek bug bounty program is the API service at https://api.keks.app/ and the application at https://keks.app/.

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.

Critical: Deletion of site data, XSS/CSRF, ACE

Payouts are handled by Cryptokek directly. Payouts are denominated in USD and are paid in KEK, ETH, or USDT/USDC (payments in currencies other than KEK may result in reduced bounty amounts)

Please note that https://cryptokek.com/ and its subdomains are excluded from the Cryptokek bug bounty program.

Cryptokek is especially interested in receiving and rewarding vulnerabilities of the following types:

• DOS
• XSS
• CSRF

Websites and Apps

• Remote Code Execution
• Vertical Privilege Escalation
• XML External Entities Injection
• Horizontal Privilege Escalation
• Stored XSS
• Reflective XSS with impact
• CSRF
• CSRF with impact
• Internal SSRF
• Session fixation
• Insecure Deserialization
• Path Traversal
• DOM XSS
• SSL misconfigurations
• SSL/TLS issues (weak crypto, improper setup)
• URL redirect

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 that rely on social engineering
• Attacks requiring access to leaked keys/credentials

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

The following vulnerabilities are not sought after for website bug reports:

• Theoretical vulnerabilities without any proof or demonstration

• Lack of SSL/TLS best practices
• DDoS vulnerabilities
• Attacks requiring privileged access from within the organization

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
• Disassembly or reverse engineering of binaries for which source code is not published, not including smart contract bytecode
• Public disclosure of an unpatched vulnerability in an embargoed bounty
