From MITRE ATT&CK 19.2

Adversaries may exploit software vulnerabilities in an attempt to collect credentials. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. 

Credentialing and authentication mechanisms may be targeted for exploitation by adversaries as a means to gain access to useful credentials or circumvent the process to gain authenticated access to systems. One example of this is MS14-068, which targets Kerberos and can be used to forge Kerberos tickets using domain user permissions. Another example of this is replay attacks, in which the adversary intercepts data packets sent between parties and then later replays these packets. If services don't properly validate authentication requests, these replayed packets may allow an adversary to impersonate one of the parties and gain unauthorized access or privileges.

Such exploitation has been demonstrated in cloud environments as well. For example, adversaries have exploited vulnerabilities in public cloud infrastructure that allowed for unintended authentication token creation and renewal.

Exploitation for credential access may also result in Privilege Escalation depending on the process targeted or credentials obtained.

How MITRE says to detect it DET0174

Detection Strategy for Exploitation for Credential Access

Windows Analytic 0493

Detects adversary exploitation of authentication mechanisms or credential validation processes. Defender perspective includes forged Kerberos tickets (e.g., MS14-068), abnormal LSASS memory access, replayed authentication attempts, and unexpected crashes of authentication services. Multi-event correlation ties exploitation attempts to abnormal process creation, service instability, and suspicious authentication events.

  • WinEventLog:Security EventCode=4768, 4769, 4770
  • WinEventLog:Sysmon EventCode=10

Linux Analytic 0494

Detects exploitation of authentication daemons or PAM modules. Defender perspective includes failed or anomalous PAM authentications, abnormal segfaults in authentication services, and exploitation attempts followed by successful unauthorized logins. Correlation identifies memory corruption, replay attempts, and privilege escalation tied to credential services.

  • auditd:SYSCALL execve: Suspicious binaries or scripts interacting with authentication binaries (sshd, gdm, login)
  • NSM:Connections Repeated failed authentication attempts or replay patterns

macOS Analytic 0495

Detects exploitation attempts against macOS authentication frameworks such as OpenDirectory or Keychain. Defender perspective includes abnormal crashes in opendirectoryd, unauthorized Keychain API usage, and unusual sudo or login events. Correlation links unexpected process behavior with credential access anomalies.

  • macos:unifiedlog opendirectoryd crashes or abnormal authentication errors
  • macos:osquery execve: Processes unexpectedly invoking Keychain or authentication APIs

Identity Provider Analytic 0496

Detects exploitation of vulnerabilities in cloud identity providers (IdPs) such as Azure AD or Okta for credential access. Defender perspective includes anomalous token creation or renewal, authentication bypass events, and API abuse to mint unauthorized tokens. Correlation highlights exploitation attempts tied to absent or inconsistent audit logs.

  • azure:signinlogs TokenIssued, TokenRenewed: Unexpected or anomalous token issuance events
  • m365:unified ConsentGranted: Abuse of application integrations to mint tokens bypassing MFA
