From MITRE ATT&CK 19.2

Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Compromised credentials may be used to bypass access controls placed on various resources on systems within the network and may even be used for persistent access to remote systems and externally available services, such as VPNs, Outlook Web Access, network devices, and remote desktop. Compromised credentials may also grant an adversary increased privilege to specific systems or access to restricted areas of the network. Adversaries may choose not to use malware or tools in conjunction with the legitimate access those credentials provide to make it harder to detect their presence.

In some cases, adversaries may abuse inactive accounts: for example, those belonging to individuals who are no longer part of an organization. Using these accounts may allow the adversary to evade detection, as the original account user will not be present to identify any anomalous activity taking place on their account.

The overlap of permissions for local, domain, and cloud accounts across a network of systems is of concern because the adversary may be able to pivot across accounts and systems to reach a high level of access (i.e., domain or enterprise administrator) to bypass access controls set within the enterprise.

How MITRE says to detect it DET0560

Detection of Valid Account Abuse Across Platforms

Windows Analytic 1543

Detection of compromised or misused valid accounts via anomalous logon patterns, abnormal logon types, and inconsistent geographic or time-based activity across Windows endpoints.

  • WinEventLog:Security EventCode=4624
  • WinEventLog:Security EventCode=4776, 4625
  • WinEventLog:Sysmon EventCode=1

Linux Analytic 1544

Detection of valid account misuse through SSH logins, sudo/su abuse, and service account anomalies outside expected patterns.

  • auditd:SYSCALL execve
  • NSM:Connections sshd or PAM logins

macOS Analytic 1545

Detection of interactive and remote logins by service accounts or users at unusual times, with unexpected child process activity.

  • macos:unifiedlog loginwindow, sshd
  • macos:unifiedlog exec logs

Identity Provider Analytic 1546

Detection of valid account abuse in IdP logs via geographic anomalies, impossible travel, risky sign-ins, and multiple MFA attempts or failures.

  • saas:okta Sign-in logs / audit events

Containers Analytic 1547

Detection of containerized service accounts or compromised kubeconfigs being used for cluster access from unexpected nodes or IPs.

  • kubernetes:audit authentication.k8s.io
