{keyword}' And (select Chr(100)||chr(85)||chr(102)||chr(83) From Sysibm.sysdummy1)=chr(100)||chr(85)||chr(102)||chr(83) And 'ikjv'='ikjv Access

The reference to SYSIBM.SYSDUMMY1 is a dead giveaway that the target is an IBM DB2 database. This is a special "one-row, one-column" table used to perform calculations or retrieve system values.

This specific payload is likely a test.

This is a final "always true" statement used to ensure the rest of the original, legitimate SQL query doesn't break the injection. What is the Goal? The reference to SYSIBM

The payload uses AND statements. For the database to return a result, the conditions following the AND must be true. This is a final "always true" statement used

If it works, the attacker will replace the "True" statement with a query that asks for sensitive data, such as: "Is the first letter of the admin password 'A'?" For the database to return a result, the

CHR(100)||CHR(85)||CHR(102)||CHR(83) translates to the string "dUfS" .The code asks the database: "Does dUfS equal dUfS?" Since this is always true, the database will process the request without an error.
