🔍 Feature: Mail Access Checker by xRisky v2

Implementation notes (best practices)

What it is

Mail Access Checker (MAC) v2 by XRisky is a tool designed to validate email credentials and check mailbox access. It automates authentication attempts against mail services (IMAP/POP3/SMTP/HTTP webmail) to determine whether supplied username/password pairs are valid and whether the account can be accessed.

How Email Providers Detect Xrisky v2

Large providers like Google, Microsoft, and Yahoo are not blind to these checkers. Their defenses include:

  1. Heuristic Rate Limiting : If 50 login attempts hit the same Gmail server from varying IPs within 10 seconds, the entire IP range is temporarily blacklisted.
  2. TLS Fingerprinting : Xrisky v2 uses specific TLS cipher suites. Gmail can fingerprint these and block non-browser, non-mobile user agents.
  3. CAPTCHA after N failures : After 3-5 failed logins, Google forces a CAPTCHA even if the password is correct, rendering automated checkers useless without costly solving services.

Review Considerations

  1. Effectiveness: Does the tool effectively perform its intended functions?
  2. Ease of Use: How user-friendly is the tool? Is it accessible to users with varying levels of technical expertise?
  3. Support and Updates: Does the developer provide good support? Are there regular updates to ensure compatibility with changing email service protocols?
  4. Safety and Privacy: How does the tool handle sensitive information? Are there any guarantees that data won't be misused?

4. Output Generation

Finally, the tool writes live credentials into a separate file, such as hits.txt or valid.txt. Attackers then use these validated accounts for further exploits.
