CAPEC-292: Host Discovery

MITRE CAPEC attack pattern

Status Stable
Typical severity Low
Likelihood of attack
Catalogue CAPEC 3.9 (2023-01-24)

Description

An adversary sends a probe to an IP address to determine if the host is alive. Host discovery is one of the earliest phases of network reconnaissance. The adversary usually starts with a range of IP addresses belonging to a target network and uses various methods to determine if a host is present at that IP address. Host discovery is usually referred to as 'Ping' scanning using a sonar analogy. The goal is to send a packet through to the IP address and solicit a response from the host. As such, a 'ping' can be virtually any crafted packet whatsoever, provided the adversary can identify a functional host based on its response. An attack of this nature is usually carried out with a 'ping sweep,' where a particular kind of ping is sent to a range of IP addresses.

Where this sits in the chain

A finding maps to a weakness (CWE), a weakness is exploited by an attack pattern (CAPEC), and an attack pattern shows up in ATT&CK as observed adversary behaviour. This page is the middle hop.

Weaknesses exploited: CWE-200

ATT&CK techniques: T1018

Prerequisites

  • The adversary requires logical access to the target network in order to carry out host discovery.

Consequences

  • Confidentiality: Other
  • Confidentiality, Access Control, Authorization: Bypass Protection Mechanism, Hide Activities
