EDR

An analytic for identifying system information discovery techniques, including the execution of wmic, systeminfo, and hostname, used by attackers to profile target environments.

This brief outlines the monitoring of curl and wget execution on Linux systems to detect the ingress of malicious tools, a common technique employed by adversaries for payload delivery and post-compromise activity.

Attackers can abuse the Linux 'at' or 'atd' utilities to maintain unauthorized access or escalate privileges by scheduling malicious tasks.

Adversaries often create new user accounts on Linux systems using 'useradd' or 'adduser' to establish persistence and facilitate privilege escalation, which can be identified through process execution monitoring.

Adversaries utilize the Get-DomainUser cmdlet within the PowerView framework to perform Active Directory reconnaissance and user enumeration.

Attackers exploit unquoted service paths on Windows systems to achieve privilege escalation by placing malicious executables in directories that the Windows Service Controller inadvertently executes with system-level privileges.

This brief details a detection strategy for identifying potential fileless execution on Linux platforms by monitoring the memfd_create syscall for anomalous process lineage and execution paths.

Adversaries abuse native macOS utilities like 'dscl', 'mkpassdb', and 'defaults' to extract user password hashes from ShadowHashData or system plist files to facilitate credential cracking and lateral movement.

This analytic detects the execution of tools commonly used by attackers for activities such as unauthorized access, network scanning, privilege escalation, password dumping, or data exfiltration, leveraging process activity data from Endpoint Detection and Response (EDR) agents to identify known attacker tool names.

This rule detects multiple external EDR alerts on the same host, indicating a potential compromise, by analyzing alert data from various EDR solutions like CrowdStrike, SentinelOne, and M365 Defender to identify hosts triggering multiple alerts, enabling prioritization of investigation and response.
