Incident investigation report

Reference C-0002 · Issued 2026-09-11 03:54:05 UTC

Demo case. The evidence in this case is synthetic and was generated by PastePile for demonstration. It is not real threat intelligence and does not describe any real organization.

What was examined

1 item(s) of evidence containing 21 record(s), covering 2026-08-25 02:14:03 UTC to 2026-08-25 17:30:19 UTC. Anything outside the evidence supplied is out of scope: nothing was collected, fetched or queried from your environment.

What was found

8 failed sign-ins for n.whitfield@example.com, then a success high

n.whitfield@example.com failed to authenticate 8 times between 02:14:03 and 02:16:02, then authenticated successfully 39 seconds later. This sequence is consistent with password guessing that eventually succeeded. It is also consistent with a user who repeatedly mistyped a password and then got it right. The successful sign-in came from 198.51.100.203, which did not appear in the failed attempts.

Recommended: Contact the account owner to confirm the activity. If unconfirmed, revoke active sessions and reset the credential, then review what the account accessed afterward.

Machines and accounts involved

n.whitfield@example.com

What could not be determined

• Whether the successful sign-in was the legitimate user is not established by authentication logs alone.
• Only the period covered by the uploaded logs was examined.
• This check needs Endpoint process creation, which was not present in the evidence.
• This check needs Email message content or headers, which was not present in the evidence.
• This check needs Directory or account audit logs, which was not present in the evidence.
• This check needs Windows service creation events, which was not present in the evidence.
• This check needs Registry modification telemetry, which was not present in the evidence.
• This check needs Email authentication results (SPF/DKIM/DMARC) or Email message content or headers, which was not present in the evidence.
• This check needs Scheduled task creation events, which was not present in the evidence.
• This check needs Security product audit events, which was not present in the evidence.
• This check needs Endpoint or network connection telemetry, which was not present in the evidence.
• 3 external indicator(s) appear in the evidence. No third-party reputation lookup has been performed; PastePile only does that on your instruction.

What we recommend

• Contact the account owner to confirm the activity Only if this activity was not expected or authorized.

What was checked

5 check(s) ran against the evidence you supplied. 29 could not run, because the evidence they need was not part of what was submitted.

A check that could not run is not a check that found nothing. These were not assessed:

• This check needs Endpoint process creation, which was not present in the evidence. 12 check(s)
• This check needs Email message content or headers, which was not present in the evidence. 5 check(s)
• This check needs Directory or account audit logs, which was not present in the evidence. 4 check(s)
• This check needs Registry modification telemetry, which was not present in the evidence. 2 check(s)
• This check needs Windows service creation events, which was not present in the evidence. 2 check(s)
• This check needs Email authentication results (SPF/DKIM/DMARC) or Email message content or headers, which was not present in the evidence. 1 check(s)
• This check needs Endpoint or network connection telemetry, which was not present in the evidence. 1 check(s)
• This check needs Scheduled task creation events, which was not present in the evidence. 1 check(s)
• This check needs Security product audit events, which was not present in the evidence. 1 check(s)

Supplying the evidence named above would let those checks run. Until then this report describes only what the submitted evidence shows.

How this was produced

The recorded outcomes above describe which evidence was processed and which checks ran. Receiving evidence alone does not mean analysis completed. No suspicious URL was visited, no attachment executed and no sample detonated. PastePile states what the supplied evidence supports and names what it does not establish; the decision about what to do remains yours.

Artificial intelligence. No language model was used in producing this case.

Findings are derived from the evidence supplied to this case and no other source.
