The credentials have not been hardcoded into the binary by the attackers themselves. The malware dynamically updates this list after using the password stealers. A new version of the binary is generated with the newly discovered credentials. This new binary will be used on the new infected systems via the propagation. This feature explains why we discovered several samples with different sets of credentials that were collected from previously infected systems.
