A contained executable was executed by an unusual process

Synopsis

Field	Value
Activation Period	14 Days
Training Period	30 Days
Test Period	N/A (single event)
Deduplication Period	1 Day
Required Data	XDR Agent
ATT&CK Tactic	Privilege Escalation (TA0004), Persistence (TA0003)
ATT&CK Technique	Escape to Host (T1611), Boot or Logon Autostart Execution: Kernel Modules and Extensions (T1547.006)
Severity	Medium

Description

A Docker-contained executable from a mounted share was executed on a host. Running a contained executable is highly dangerous and atypical.

Attacker's Goals

Gain high privileged command execution on the host machine via one of its running containers.

Investigative actions

• Check what actions were made after the suspicious file execution.
• Investigate the contained process and its process tree.

Variations

A contained executable was executed by the Linux kernel thread daemon

ATT&CK Technique	Escape to Host (T1611), Boot or Logon Autostart Execution: Kernel Modules and Extensions (T1547.006)
Severity	High

Description

A contained executable in a cloud machine was executed by the Linux kernel thread daemon. This behavior is suspicious as it may be a result of an attacker attempting to escape from a container, as the kernel thread daemon is usually used to spawn kernel processes only.

Attacker's Goals

Gain high privileged command execution on the host machine via one of its running containers.

Investigative actions

• Check what actions were made after the suspicious file execution.
• Investigate the contained process and its process tree.
