## What is LOG//TRACE?

Read the logs. Follow the traces of an attack. A security detective game for your phone.

All a client hands you is a server's logs. Authentication logs, access logs, mail headers, event logs... From the traces left behind, work out what happened and present the line that proves it.

HOW IT PLAYS
- Filter the log and hunt for the suspicious line
- Pick the evidence line and present it
- Move between several traces (logs, mail headers, process lists) and connect the whole picture
- Solve the case to read a report explaining the techniques and how to defend

FEATURES
- Log formats close to the real thing, so you build the skill of reading logs
- Techniques are explained with MITRE ATT&CK IDs, and every technique you solve is collected in the Technique Index
- Learn the practical way of thinking: telling false positives apart, scope of damage, timeline, first response, and recovery
- Fewer mistakes and hints earn more stars. Aim for three
- Your investigation is saved automatically. No account, no ads
- Available in English and Japanese

THE CASES
Tracking series (6 chapters): from the prologue "The Midnight Visitor", follow the traces of one attacker working behind the scenes

The prologue through Chapter 2 are free. Later chapters unlock with a single one-time purchase, the "Premium Pass" (not a subscription).
