As part of the reconnaissance phase, attackers gather information about the entities in the network using different methods. Directory services enumeration using the SAM-R protocol enables attackers to obtain the list of users and groups in a domain and understand the interaction between the different entities.

To enhance Pass-the-Hash detection, we added additional behavioral models for the authentication patterns of entities. These models enable ATA to correlate entity behavior with suspicious NTLM authentications, and differentiate real Pass-the-Hash attacks from the behavior of false positive scenarios.

To successfully detect advanced attacks in general and Pass-the-Ticket in particular, the correlation between an IP address and the computer account must be accurate. This is a challenge in environments where IP addresses change rapidly by design (for example Wi-Fi networks and multiple virtual machines sharing the same host). To overcome this challenge and improve the accuracy of the Pass-the-Ticket detection, ATA’s Network Name Resolution (NNR) mechanism was improved significantly to reduce false-positives.

In ATA 1.7, NTLM authentication data was added as a data source for the abnormal behavior detections, providing the algorithms with broader coverage of entity behavior in the network.
ATA now detects unusual protocol implementation in the Kerberos protocol, along with additional anomalies in the NTLM protocol. Specifically, these new anomalies for Kerberos are commonly used in Over-pass-the-Hash attacks.
