Scenario

A Finance user clicked the wrong shortcut. What looked like a Q2 remittance PDF was a more like a loader, now we're dealing with persistence, and outbound activity.

Now it's your turn to hunt through the box, find what landed where, and rip the implant apart.

What You'll Do

A hands-on incident response and reverse engineering challenge running alongside ContinuumCon 2026 workshops and AMAs.

Every player gets a pre-compromised Windows workstation with artifacts. You investigate, and solve the challenges.

The technical investigation:

  • Trace initial access from the phishing ZIP
  • Find what landed on disk and the multiple ways it survives reboot
  • Reverse engineer the implant
  • Triage any binaries found and any C2 activity you may find
  • Hunt indicators of compromise across

The analytical writeup:

  • Short-answer questions on threat intelligence and MITRE ATT&CK mapping
  • Short-answer questions on detection engineering, including Sigma and YARA rule authoring
  • Short-answer questions on governance, risk, and compliance
  • An incident report with executive summary, technical analysis, and remediations

This challenge scales with you.

  • Beginners can capture IOCs from the artifacts and write the report
  • Intermediate players will dig into persistence, dropper analysis, and detection authoring
  • Advanced players will reverse the malware, and capture every flag the live C2 has to offer

Skills covered

  • LNK and PowerShell analysis
  • Windows persistence hunting
  • Reverse engineering and string deobfuscation
  • Custom protocol analysis
  • Live C2 interaction
  • Detection engineering
  • Threat intelligence reasoning
  • GRC analysis considerations
