Security Key Telegram Fix ((exclusive)) - Kaspersky Internet

| Concern | Mitigation | |---------|------------| | | - Keys are never stored on disk; only held in RAM for < 10 min. - Bot masks user input (Telegram automatically hides characters after a short delay). | | Impersonation | - Require email‑OTP or KSA OAuth before any key‑changing operation. - Verify that the Telegram user ID is linked to the email via a one‑time confirmation (store a short‑lived mapping). | | Brute‑Force / Rate‑Limiting | - 3 attempts per hour per user; exponential back‑off after repeated failures. - IP‑based throttling on the backend API. | | Data Retention | - No raw keys logged. Audit logs contain only hash(email) + operation code. - Logs auto‑purge after 90 days. | | Compliance | - GDPR “right to be forgotten”: users can send /delete → bot removes any cached session data immediately. - Privacy policy link displayed on /start . | | Telegram Platform Risks | - Encourage users to use Secret Chats for added end‑to‑end encryption (optional). - Bot never requests personal data beyond email & key. | | Supply‑Chain | - Bot code signed with internal GPG key. - Use official Telegram Bot API library (latest stable version). |
