LLM-Based Triage of Wget Activity on Linux Hosts
1 rule 3 TTPs 13 IOCsElastic has developed a detection rule that monitors non-allowlisted `wget` activity on Linux hosts using Auditd Manager or Auditbeat, leveraging an Elastic LLM to triage `wget` executions for potential ingress tool transfer, command and control, or data exfiltration attempts to untrusted destinations, generating alerts only for high-confidence positive or suspicious verdicts.
LLM-Based Detection of Suspicious Curl Activity on Linux
3 TTPsElastic's LLM-based detection rule identifies suspicious `curl` activity on Linux systems, aiming to detect command and control, data exfiltration, or ingress tool transfer by analyzing command-line parameters and network destinations via Auditd Manager or Auditbeat logs, which, if left unaddressed, could lead to system compromise or data breach.
AWS S3 Rapid Bucket Posture API Calls from a Single Principal
4 TTPsThis detection rule identifies suspicious activity in AWS environments where a single principal, from a consistent source IP, rapidly performs read-only S3 control-plane API calls across more than 15 distinct S3 buckets within a 10-second window, indicative of automated reconnaissance, security scanning, or post-compromise enumeration aiming to map S3 bucket access, policies, and versioning.
