Detect execution of a network utility executed from a suspicious location on a host.
After an attacker’s initial intrusion into a host (for example, through a web shell exploit, or a container breakout), they may attempt to use network utilities for a variety of malicious purposes (for example, reconnaissance, or data exfiltration). This detection triggers when execution of one of a set of network utilities (for example, nslookup
, netcat
) is detected on a host. Different utilities may serve different purposes in an attack; for example, DNS tools like nslookup
could be involved in a DNS data exfiltration attack, and netcat
could indicate a backdoor and data exfiltration. If this is unexpected behavior, it could indicate an attacker attempting to compromise your host.
These utilities executed by a file located in /tmp
or another writeable directory could indicate a malicious script attempting to perform actions on the host. These actions may include downloading additional tools or exfiltrating data.
Requires Agent version 7.34 or greater
