IN-SCOPE VULNERABILITIES (WEB)
We are interested in the following vulnerabilities:
Critical
- Remote code execution (RCE)
- Business logic issues can theft a lot of funds
- False top-up issues
- Leakage of sensitive information with a massive amount (KYC)
- Other security vulnerabilities that we consider to be critical
High
- Business logic issues can lead to user fund loss
- Injection vulnerabilities (SQL, XXE)
- Access Control Issues (IDOR, Privilege Escalation, etc) can theft user funds.
- Leakage of sensitive information with a small amount (KYC)
- Server-Side Request Forgery (SSRF)
- Other security vulnerabilities that we consider to be high
Medium
- Cross-Site Scripting (Stored XSS)
- Leakage of information(Email, Uid...)
- Business logic issues can lead to denial of service
- Other security vulnerabilities that we consider to be medium
Low
- Directory traversal
- Leakage of information(System log, tracking data...)
- Cross-Site Scripting (Reflection XSS)
- Cross-Site Request Forgery (CSRF)
- Open redirects
- Other security vulnerabilities that we consider to be low
IN-SCOPE VULNERABILITIES (Mobile)
We are interested in the following vulnerabilities:
Critical
- Remote code execution (RCE)
- Authentication bypass (biometric / passcode lock / 2FA / withdrawal verification) leading to account takeover or theft of user funds without high interactivity
- JSBridge / JavascriptInterface (Android) / WKScriptMessageHandler (iOS) exposure that allows untrusted pages or domains to invoke sensitive methods (e.g., obtain session tokens, place orders, transfer or withdraw funds) without high interactivity
- Account takeover via the mobile app (e.g., hijacking of OAuth/login callbacks through URL schemes or universal links / app links)
- Other vulnerabilities with comparable impact, at our discretion
High
- Leakage of sensitive data without root/jailbreak or physical access. Sensitive data includes session tokens, private keys/mnemonics, passwords, API keys, KYC data, and other users' personal information
- Hard-coded secrets with demonstrable impact (e.g., cloud storage AK/SK, push service server keys, API signing keys, internal service tokens, payment keys)
- Insecure WebView configuration with a working exploit (e.g., arbitrary file read via file:// access, universal file access from file URLs)
- Exported components (Activity/Service/Broadcast Receiver/Content Provider) or intent redirection that leak sensitive data or perform sensitive actions
- Insecure local storage readable by other apps on non-rooted devices (e.g., tokens in external storage or world-readable files)
- Client-side input that leads to server-side injection (e.g., SQL injection) is evaluated under the Web/API scope
- Remote, persistent DoS that renders the app unusable until reinstalled
- Other vulnerabilities with comparable impact, at our discretion
Medium
- Reflected XSS within app WebViews (rated higher if it can reach sensitive JSBridge methods)
- Unrestricted arbitrary URL loading via deeplink / URL scheme / universal link / app link without further impact
- Biometric / passcode lock bypass requiring physical access to an unlocked or locked device, without direct fund loss
- Remote DoS that can be repeatedly triggered and requires an app restart
- Client-side SQL injection in local databases with demonstrable sensitive impact
- Other vulnerabilities with comparable impact, at our discretion
Low
- Phishing via WebView (e.g., URL/address bar spoofing, misleading title) without further impact
- Sensitive data (passwords, mnemonics, private keys, 2FA codes) written to the system clipboard without user intent or auto-clearing
- Other vulnerabilities with comparable impact, at our discretion
IN-SCOPE Threat Intelligence
The following types of threat intelligence findings are considered in-scope and eligible for rewards when they demonstrate a clear, actionable risk to Bitunix Exchange, its users, or its brand. Submissions must include verifiable evidence (screenshots, URLs, sample communications, malware hashes, etc.) and a clear explanation of the impact.
- Phishing websites and domains that impersonate the Exchange (including look-alike domains, fake login portals, fake KYC pages, or fake customer support sites).
- Fake mobile applications (Android/iOS) distributed outside official app stores that impersonate the official Exchange app or claim to offer trading, deposits, withdrawals, or customer support on behalf of the Exchange.
- Social media and messaging platform impersonation (Twitter/X, Telegram, Discord, Facebook, Instagram, WhatsApp, etc.) involving fake official accounts, support channels, or community groups that actively attempt to defraud users.
- Malicious advertising and SEO poisoning campaigns that promote fake Exchange-related pages, fake airdrops, or fake giveaways.
- Targeted malware, phishing kits, or credential-stealing infrastructure specifically designed to target Exchange users (including but not limited to fake wallet connection prompts, fake browser extensions, or info-stealers configured for Exchange domains).
- Active fraud campaigns (including investment scams, fake recovery services, or “account verification” scams) that misuse the Exchange’s name, logo, or branding.
- Leaked or exposed sensitive operational data that can be leveraged by threat actors against the Exchange or its users (e.g., internal employee credentials found in the wild, exposed threat intelligence feeds related to the Exchange, or compromised partner infrastructure directly affecting Exchange security).
- Supply-chain or third-party threats that directly impact the Exchange’s users or systems when clear evidence of active exploitation or high likelihood of exploitation is provided.
