The scope of the bug bounty program is limited to technical vulnerabilities in the company's services. If you discover other issues that are not security-related, please contact the support team.

Reports submitted by current or former employees (within one year after termination of employment) of YooMoney are accepted but are not eligible for a monetary reward.

Participants are required to keep the information about the discovered vulnerabilities confidential. Disclosure of such information is only permitted with prior written consent from YooMoney.

Participation in this program implies that you have read the program rules and you agree to them. Violations of the rules or other program terms may result in disqualification from receiving a reward.

### RESPONSE TIME
We aim to meet the following response targets:
- Response time (from the moment information is received): up to 5 business days.
- Report processing time (from the moment all information on the report is received): up to 10 business days.
- Reward payment time (from the moment the report is processed): up to 20 business days.

Response times may be extended during national public holidays or periods of high workload. We will keep you informed of our progress at each stage of the process and will notify you if delays occur.

### REPORT FORMAT
Each report should describe a single vulnerability, except for cases where vulnerabilities are related or can be combined into a chain.

Failure to meet the minimum report requirements may reduce the reward amount up to the denial of payment in case the report does not contain enough information for verification. 

All information about the discovered vulnerability (including attachments) must be kept solely within the report. Publishing such information on external resources is prohibited.

A report must include:
- Description of the vulnerability
- Type of vulnerability discovered
- URL of the vulnerable application
- Steps to reproduce (with sample requests)
- Screenshots or video confirming the vulnerability
- Severity analysis
- Remediation recommendations

### RULES
**TESTING RULES**
- Use only your own accounts or accounts of users who have explicitly given consent for testing. Do not attempt to access any confidential information or accounts that belong to other people;
- Any activity that may damage the company’s applications, infrastructure, customers or partners is prohibited;
- For proof-of-concept purposes, use the minimal actions necessary to confirm a vulnerability. If testing may affect other users or system availability, contact us for permission. Further exploitation of vulnerabilities is strictly forbidden;
- Social engineering directed at YooMoney employees, partners, contractors or users is prohibited;
- Physical attacks against the company or its infrastructure are prohibited;
- Exploitation of vulnerabilities after testing is complete is prohibited;
- Automated scanning must be limited to 5 requests per second.


**RCE Testing Policy**
Testing for vulnerabilities that may lead to remote code execution must comply with this policy.
Only actions allowed to be performed on servers during testing:
- Executing commands: ifconfig (ipconfig), hostname, whoami;
- Reading files: "/etc/passwd" and "/proc/sys/kernel/hostname" (or "drive:/boot.ini", "drive:/install.ini");
- Creating an empty file in the current user's working directory.
Any other actions require prior approval from the YooMoney security team.

**SQL Injection Testing Policy**
Testing for vulnerabilities that may allow SQL injection must comply with this policy.
During testing, only the following actions are allowed:
- Retrieving information about the current database (SELECT database()), its version (SELECT @@version), current user (SELECT user(), SELECT system_user()), or host name (SELECT @@hostname);
- Retrieving database scheme (SELECT table_schema), list of tables (SELECT table_name), and column names (SELECT column_name).
Any other actions require prior approval from the YooMoney security team.

**File Upload and Read Policy**
Testing for vulnerabilities that may allow arbitrary file read or arbitrary file upload must comply with this policy.
Prohibited actions when uploading files:
- Modifying, changing, deleting, or replacing any files on the server (including system files), except files associated with the researcher’s account or with a user account that has explicitly given consent, provided this does not disrupt the service or its parts;
- Uploading files that could cause denial of service (for example, very large files or a very large number of files);
- Uploading malicious files (for example, malware or spyware).

If arbitrary file reading is possible, the following actions are allowed:
- Reading only these files:"/etc/passwd" and "/proc/sys/kernel/hostname" (or "drive:/boot.ini", "drive:/install.ini").
Any other actions require prior approval from the YooMoney security team.

### DISCLOSURE RULES
- Disclosure of discovered vulnerabilities or any information regarding the report without written permission from the YooMoney security team is prohibited;
- Submit reports only through the platform form;
- We reserve the right to decline any request for public disclosure of a report.


### DUPLICATE REPORTS POLICY
We pay a reward only for the first report received that contains all necessary data to reproduce the vulnerability.
All subsequent reports containing information about the same vulnerability are considered duplicates and are not eligible for an additional reward.
A report may be considered a duplicate of another researcher’s report or an internal security team report.
A report may also be considered a duplicate if it contains information about attack vectors that are being fixed following the processing of another report.

### CRITICALITY DETERMINATION RULES
We reserve the right to make the final decision about reported vulnerability’s severity. When we receive a report, we perform an internal investigation and determine its severity considering several factors:
- The privileges an attacker needs to exploit the issue;
- How difficult it is to discover and exploit the vulnerability;
- Whether user interaction is required;
- Impact on integrity, availability, and confidentiality of affected data;
- Data integrity, availability, and confidentiality requirements for the affected data;
- Impact on business and reputational risk;
- How many users would be affected by the vulnerability.
One of the tools we use for analysis is the CVSS v3.1 scoring calculator.

### REWARD
Rewards are paid to participants only for previously unknown security issues that meet all conditions specified in the program.

The table below shows the maximum amount of remuneration for each severity level.

Severity level — Maximum reward amount (RUB)
Critical: 150,000 – 400,000 ₽
High: 35,000 – 150,000 ₽
Medium: 7,500 – 35,000 ₽
Low: 1,000 – 7,500 ₽

For mobile applications, three severity levels are used: High, Medium, Low.

The amount of the reward is determined by YooMoney on a case-by-case basis, with the criteria outlined in this program taken into consideration and within the specified ranges.
