This hunt detects adversary activity involving the Sliver C2 framework by identifying matches against a curated set of 57 specific Indicators of Compromise (IOCs). A SOC team should proactively search for these signals in Azure Sentinel to rapidly identify and contain potential Sliver-based intrusions, which are frequently used by advanced threat actors for stealthy command and control operations.

Here are 4 specific false positive scenarios for the ThreatFox: Sliver IOCs detection rule, including recommended filters and exclusions tailored for an enterprise environment:
DevOps Pipeline Artifact Deployment
SYSTEM account or specific service accounts (e.g., svc-jenkins, gitlab-runner) where the parent process is jenkins.exe, gitlab-workhorse.exe, or azdo-agent. Additionally, filter out events occurring on known build server subnets (e.g., 10.20.x.x).Endpoint Security Agent Updates
falcon-sensor.exe, SentinelOneAgent.exe, or cb.exe (Carbon Black) where the file path is located in the standard installation directory (e.g., C:\Program Files\CrowdStrike\). Exclude these events if the parent process is the specific security service itself.Scheduled Patch Management Jobs
