EternalSafety is a Zeek package for detecting potentially-dangerous SMBv1 protocol violations that encapsulate bugs exploited by the infamous Eternal* family of Windows exploits. It is capable of detecting EternalBlue, EternalSynergy/EternalRomance, EternalChampion, and the DoublePulsar backdoor. However, rather than identifying these exploits via simple signature-matching, *EternalSafety* instead implements a set of SMBv1 protocol invariants that encapsulate techniques used by each Eternal* exploit to trigger bugs in unpatched Windows systems. EternalSafety accurately and reliably identifies the EternalBlue, EternalSynergy and EternalRomance exploits, and the DoublePulsar backdoor implant. Due to limitations in Zeek's SMBv1 support, it has limited support for detecting EternalChampion via signature-matching. EternalSafety also identifies a range of other protocol violations, such as the use of unimplemented/unused SMBv1 commands, server-initiated changes in values that may only be set by an SMBv1 client, and incorrect interleaving of transaction types.

This package offers the possibility of exfiltration detection through statistical analysis methods. For this purpose, all connections are added to a baseline, subdivided according to their source ip address and destination port. The baseline is then used to perform statistical anomaly detection. Anomalies in the baseline are considered as data exfiltrations. The severity of the anomaly is recorded using a score between 0 and 1.

This plugin adds support for shell-style glob patterns when loading Zeek scripts. For example, saying "@load startup.d/*.zeek" will load any Zeek scripts with a .zeek suffix from the startup.d folder.
