Why it matters
Running a scanner is the easy part; the job is deciding what the results mean. A single Nuclei run against a real scope prints hundreds of lines, most of them informational, and a beginner either panics at all of them or skims past the one that matters. The people who get hired can look at that wall of output and, in a minute, point at the finding that ends the engagement if left alone, dismiss the noise with a reason, and flag the line that is probably a false positive before it ever reaches a report. That triage — read the line, understand what was actually checked, confirm it, rank it — is…
What you'll learn
- reading a Nuclei finding line: template-id, protocol, severity, matched-at
- using the template-id as the lead to learn exactly what was checked
- severity triage — why info/low is usually context, not action
- separating an exposed panel / known-CVE hit from a mere tech fingerprint
- confirming a finding by reproducing what the template matched, before escalating
- spotting a likely false positive (a matcher tripped by a catch-all page)
- producing a prioritized investigation list from raw scan output
- judgment: a clean Nuclei scan is not a secure target
Steps in this lab
- The scenario, and how to read one finding line
- The output — read all of it before touching anything
- Severity triage — why the pile of info is mostly context
- The two that demand action now — and why the template-id proves it
- Confirm before you believe — and the false positive hiding in plain sight
- Write the prioritized investigation list
- The judgment to keep: a clean scan is not a secure target
