Adversaries may attempt to get a listing of valid accounts, usernames, or email addresses on a system or within a compromised environment. This information can help adversaries determine which accounts exist, which can aid in follow-on behavior such as brute-forcing, spear-phishing attacks, or account takeovers (e.g., Valid Accounts).
Adversaries may use several methods to enumerate accounts, including abuse of existing tools, built-in commands, and potential misconfigurations that leak account names and roles or permissions in the targeted environment.
For examples, cloud environments typically provide easily accessible interfaces to obtain user lists. On hosts, adversaries can use default PowerShell and other command line functionality to identify accounts. Information about email addresses and accounts may also be extracted by searching an infected system’s files.
Platforms: ESXi, IaaS, Identity Provider, Linux, macOS, Office Suite, SaaS, Windows
Identify Attack Surface: Determine if the target environment is susceptible to Account Discovery by examining the target platforms (ESXi, IaaS, Identity Provider).
Assess Existing Defenses: Review whether mitigations for T1087 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.
