Claim 5:
6. An attack detection method for enhancing cybersecurity, comprising:
determining that a passphrase used in a failed sign-in to a target account from a source location is a weak credential;
in response to the determining, updating a measure of weak credential failed sign-ins;
ascertaining that the updated measure satisfies an access restriction condition;
in response to at least the ascertaining, imposing an access restriction on at least one of the target account and the source location;
whereby the method enhances cybersecurity by detecting behavior which indicates an identity attack and by imposing an access restriction in response to the behavior, and wherein said detecting is based on at least both noting sign-in failure and determining credential weakness.
