Maromalix Nightmare
Threat Hunting, Endpoint Forensics
mediumA deal was stolen before it was ever signed. Someone got in, found exactly what they needed, and vanished. Your job is to prove it.

Penumbra
Endpoint Forensics
mediumCommunity rating: hardSynthesize diverse forensic artifacts including $MFT, USN journal, and registry hives to reconstruct an anti-forensic intrusion timeline from initial access to exfiltration.

ClickFix - VodkaStealer
Threat Hunting
mediumAnalyze Splunk event logs to reconstruct a multi-stage attack chain, detailing initial access, privilege escalation, lateral movement, and data exfiltration.

Shadow Token Symphony - APT29
Cloud Forensics
mediumSynthesize KQL findings across Windows events and Azure logs to reconstruct an APT29 multi-stage cloud attack, identifying persistence mechanisms and data exfiltration.

Poisoned PyTorch
Threat Hunting
mediumInvestigate a software supply-chain compromise that escalates into a ransomware attack, with emphasis on identifying pre-encryption operations.

ConsentStorm
Cloud Forensics
mediumInvestigate a cloud OAuth intrusion by identifying malicious consent grants (Q1-Q4), tracing service-account pivots and Azure enumeration (Q5-Q11), validating persistence through app secrets, TAP abuse, and group changes (Q12-Q17), analyzing file access and exfiltration (Q18-Q19), and mapping tradecraft to ATT&CK and Entra mitigations (Q20-Q25).

KioskExpo7
Endpoint Forensics

Stolen Time - HiddenTear
Threat Hunting
mediumSynthesize and correlate diverse forensic artifacts from multiple systems to reconstruct the complete HiddenTear attack chain and attribute threat actor TTPs.

Nitrogen - Blackcat Ransomware
Threat Hunting
mediumReconstruct multi-stage ransomware attack by correlating Splunk telemetry, disk forensics, and registry artifacts to identify persistence mechanisms, credential dumping, and lateral movement.
