Overview
What this tool is designed to do
This page focuses on fast, human-in-the-loop triage of log snippets. It is not a full SIEM or correlation
engine. Instead, it helps you answer practical questions such as which IP addresses are especially noisy and
where failed login attempts are concentrated.
You can paste log lines directly into the tool or upload a small .log or
.txt file from your machine. The browser then counts IP frequencies, highlights
failed login phrases, and lets you search for custom patterns using simple text or regular expressions.
Client-side only, no upload
Works with many plain-text logs
When this tool is a good fit
The Log File Pattern Finder is most helpful when you have a small slice of log data and you want a quick sense
of what is happening before you move into heavier tooling. Examples include:
- A few hundred SSH or VPN lines from a lab or personal server.
- Web server access logs for a short time window, for example the last few minutes around an error.
- Application logs from a self-hosted service where you suspect a noisy client or misconfiguration.
The analysis is shallow on purpose. It gives you a starting point, not a conclusion. You still review the
context, your threat model, and any compliance obligations before taking action.
Tip.
For best results, trim very large logs down to a focused snippet such as the last 500 to 2000 lines, especially
around the timeframe where you suspect an issue.
How it works
Key features and workflow
The Log File Pattern Finder reads only the text that you paste or upload into the page. It does not contact a
server, store your logs remotely, or send them to CyberLife Coach. All processing happens in the browser’s
JavaScript engine.
Typical workflow.
- Paste log lines or upload a small log file into the input area.
- Select “Analyze log” to calculate total lines, distinct IP addresses, and failed-login candidates.
- Review the list of top IP sources and decide which ones matter in your environment.
- Scan the failed-login section and note usernames, sources, and timing of repeated attempts.
- Use the custom search field to look for specific paths, user agents, or application markers.
Limitations and safe use
This tool does not replace central logging, alerting, or incident response. It will not detect every attack
technique, and it does not maintain log history beyond what you paste or upload during the current session.
Avoid pasting highly sensitive content such as credentials, secrets, or regulated personal data. If your
organization has policies that restrict log exports or require approved tooling, follow those policies first
and treat this helper as an optional, local-only viewer where it is allowed.
Important.
Treat every pattern here as a lead, not a verdict. A noisy IP might be an internal scanner, a staging system,
or a legitimate integration. Always correlate with known assets, change history, and your existing security
controls.
