Log File Pattern Finder

Paste a small server or application log, or upload a log snippet from your machine, then quickly surface suspicious patterns such as failed logins and noisy IP addresses. Everything runs locally in your browser.

1. Add a log snippet

Client-side only

Use this tool for small to medium log excerpts you are allowed to inspect locally. Large SIEM exports or highly sensitive logs should be handled with your organization’s approved tooling and workflows.

Tip · Start with a few hundred lines rather than full-day logs.
Safe · Files stay in your browser, not sent to CyberLife Coach.
Scope & limitations. This helper is meant for quick, human-in-the-loop triage, not full incident response. It will not detect every attack pattern, and it does not replace log retention, SIEM correlation, or professional monitoring.

2. Review the patterns

Summaries update after each analysis.

Paste a log snippet and select “Analyze log” to populate these fields.
IP FREQUENCIES · Top sources

High-frequency sources can hint at brute-force attempts, misbehaving clients, or noisy scanners.

    FAILED LOGINS · Suspicious lines

    Uses common text patterns such as failed password, invalid user, authentication failure. Always validate against your environment.

    CUSTOM SEARCH · Regex or simple text

    Search for additional patterns, for example specific usernames, user agents, or paths. Simple text works, or you can use a regular expression.
