Blue Team Labs
Put your knowledge into practice with gamified cyber security challenges.

BPFDoor - StraitsTelecom
Endpoint Forensics
mediumCommunity rating: hardInvestigate a two-host Linux intrusion using live triage collections and a network capture: analyse authentication, audit and login records, detect a backdoor that never opens a port, statically analyse a stripped ELF implant, and recover data from an encrypted command-and-control channel.

ActiveMQ - LockBit Ransomware
Threat Hunting
mediumCommunity rating: easyReconstruct a full-chain ransomware attack that began with a single CVE in the DMZ and ended with domain-wide compromise, data exfiltration, and encrypted file servers.

CodeFreeze 2
Endpoint Forensics
mediumReconstruct a multi-stage attack timeline by analyzing forensic artifacts from browser, VSCode, WSL, registry, and application logs.

Crossed Signals
Endpoint Forensics
mediumA routine security audit. A trusted messaging app. By the time the victim realized something was wrong, the damage was already done. Can you trace what happened?

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.

Tax Day - BYOVD
Endpoint Forensics
mediumCorrelate forensic artifacts from event logs, browser history, and prefetch with static analysis using IDA Pro to reconstruct a BYOVD attack chain and defense evasion tactics.

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.

CodeFreeze
Endpoint Forensics
mediumReconstruct the complete attack timeline by analyzing browser history, event logs, registry, and Git artifacts to identify initial access, persistence, and data exfiltration mechanisms.

Rhadamanthys
Endpoint Forensics
mediumHunt mail caches, MFT records, and Prefetch to unmask the initial dropper and rebuild the attack timeline.

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.
