Detection of an attack on a data processing system. An example method comprising, in the data processing system: providing an initial secret; binding the initial secret to data indicative of an initial state of the system via a cryptographic function; recording state changing administrative actions performed on the system in a log; prior to performing each state changing administrative action, generating a new secret by performing the cryptographic function on a combination of data indicative of the administrative action and the previous secret, and erasing the previous secret; evolving the initial secret based on the log to produce an evolved secret; comparing the evolved secret with the new secret; determining that the system is uncorrupted if the comparison indicates a match between the evolved secret and the new secret; and, determining that the system in corrupted if the comparison indicate a mismatch between the evolved secret and the new secret.
