Abstract: Methods and systems for detecting and preventing malicious software activity are presented. In one embodiment, a method is presented that includes monitoring network communications on a network. The method may also include detect a suspect network communication associated with a suspect network activity and, in response, determine an originating machine based on the suspect network activity. The method may further suspend network communications for the originating machine. A forensics software agent may then be selected based on the suspect network activity. Then, the forensics software agent may be deployed on the originating machine. After deployment, the forensics software agent may fetch computer forensics data from the originating machine. Once the computer forensics data is fetched, a response action may be selected and executed based on said computer forensics data.

Abstract: Methods and systems for detecting forged Kerberos protocol tickets are presented. In one embodiment, a method is presented that includes receiving and decrypting an authentication request including a ticket. A validity start time and a validity end time may then be extracted from the ticket and a validity period may be calculated based on the validity start time and the validity end time. The method may then include retrieving a domain validity period from a domain controller and comparing the validity period to the domain validity period. If the validity period differs from the domain validity period, the authentication request may be blocked.
