Windows Event ID 5858 — WMI Provider Error
Logged when a WMI provider operation fails. Contains the provider name, error code, and the initiating process — useful for detecting failed WMI execution attempts and probing activity.
MITRE ATT&CK
T1546.003 · Windows Management Instrumentation Event Subscription

Why It Matters
Attackers probing WMI capabilities or using malformed subscriptions generate 5858 errors before successful exploitation. A burst of 5858 events from an unexpected process or user is a reconnaissance signal. 5858 also helps identify failed WMI lateral movement attempts (Invoke-WmiMethod, wmiexec) where the attacker's command did not fully execute.
Key Fields
Investigation Tips
- 1.Multiple 5858 errors from powershell.exe or an unexpected host process indicate WMI probing or a failed lateral movement attempt via Invoke-WmiMethod or wmiexec.
- 2.WBEM_E_ACCESS_DENIED errors from a non-admin process can indicate an attacker attempting WMI operations without sufficient rights — check what account triggered them.
- 3.Correlate 5858 errors with 5857 successes — attackers often generate errors while establishing WMI subscriptions, then succeed on a later attempt.
- 4.Is this always malicious? No — WMI errors occur frequently due to misconfigured management software, network timeouts, and permission issues. Focus on unexpected source processes and repeated errors targeting the subscription namespace.
