MySQL data exfiltration uses built-in functionality to pull data out of the database. SELECT INTO OUTFILE writes query results directly to the filesystem when the server has FILE privilege and a writable path.

Full database dumps with mysqldump capture schemas, data, and stored procedures in one operation. Binary log extraction recovers historical queries and data changes, potentially exposing deleted records and previous credential values.
