Abstract:
1. A system for protecting against information security breaches, comprising: a client computer including a processor coupled to computer-readable storage media containing instructions executable by the processor for implementing a credential module that maintains a set of security credentials that are each associated with corresponding known computing systems, wherein the credential module detects when security credentials of the set of security credentials are to be used; and a protection module implemented by the processor that detects use of security credentials of the set of security credentials in connection with an unverified computing system other than the associated known computing systems, wherein the protection module is configured to report the use of the security credentials with the unverified computing system in a report to a security server, wherein the security server determines that the unverified computing system is engaged in malicious activity when a number of reports of the use of the security credentials with the unverified computing system received from the client computer and one or more other client computers exceeds a predetermined threshold.
