Detection Engineering & Incident Response: CVE-2026-29058

Respond to a live compromise of a WWBN AVideo host (CVE-2026-29058). Reconstruct the attack timeline from correlated logs, determine impact and find the attacker's persistence, engineer and tune a behavioral detection rule to zero false negatives and false positives, then contain, eradicate, verify and report.

The scenario

Triage already confirmed this host runs a vulnerable AVideo. Overnight the SIEM correlated something worse: probing, then a success, then a new process and an outbound connection. You are the Tier-2 responder. Open the incident and classify what you are dealing with before you dig in.

What you will do

  1. Open and classify the incident4 steps

    Move into the incident folder · Read the correlated SIEM alert · Read the incident ticket · Classify the incident

  2. Reconstruct the timeline4 steps

    Pull the attacker’s web requests · When did the attack succeed? · Correlate the application log · Which process confirms execution?

  3. Determine the impact4 steps

    Inspect the captured crontab · Inspect the network snapshot · What is the attacker’s foothold? · Record the indicators of compromise

  4. Engineer a detection rule4 steps

    Study the replay sample · Write a first rule · Test the rule · Why not just block the IP?

  5. Contain and eradicate5 steps

    Block the attacker IP · Apply the compensating control · Patch to the fixed version · Remove the persistence · …

  6. Verify detection and report3 steps

    Confirm detection still fires · Write the incident report · Why eradication matters

How this lab works

A real Linux-style console. Commands run against real files, so hashes, hex dumps and comparisons give real results.

A file browser where you can place evidence into the lab, either the file provided or one of your own.

Reset a single step, a whole task or the entire lab. The environment is rebuilt so you can try again cleanly.

Progress saves after every step. Close the tab and come back later; your files and answers are waiting.
