This rule detects modifications to the PostgreSQL authentication configuration file (pg_hba.conf), which controls client authentication. It also identifies replication connection requests from source IP addresses that have not been observed in the previous 7 days, indicating a potential attempt to exfiltrate database data via unauthorized replication.

This rule monitors Syslog entries for PostgreSQL 'CREATE_REPLICATION_SLOT' commands to identify potential exploitation attempts associated with CVE-2026-6471. It detects attempts to load logical decoding plugins using suspicious path structures, including path traversal sequences ('../', '..\'), absolute paths, or UNC paths, which are not present in a known-good allowlist of plugins.

Detects suspicious behavior from database accounts with replication privileges ('rolreplication=true'). The rule monitors for logins from unauthorized IP addresses, the execution of non-replication related SQL commands by these accounts, and the use of potentially malicious plugin names (containing path traversal characters) during replication slot creation.

Detects the creation of a PostgreSQL replication slot using an unrecognized or potentially malicious logical decoding plugin. Adversaries may use custom or unauthorized plugins to exfiltrate database contents or intercept replication data streams, bypassing standard monitoring for common plugins like pgoutput or test_decoding.

Detects the initialization of PostgreSQL logical replication slots using uncommon or unrecognized output plugins. Attackers may leverage logical replication plugins to exfiltrate data from a database by streaming changes as they occur, which can be an alternative to traditional mass-export techniques.

Detects anomalous system reconnaissance activity performed using WMIC or PowerShell Get-WmiObject commands. The rule tracks distinct command-line executions per device and flags hosts where three or more unique reconnaissance commands are executed within a short timeframe, which is indicative of an adversary enumerating system configuration, hotfixes, or hardware details.
