Put your knowledge into practice with gamified cyber security challenges.

Lespion
Threat Intel
easyInvestigate an insider threat by analyzing GitHub repositories for exposed credentials, using OSINT tools to correlate online accounts, and performing image analysis to identify locations.

Insider
Endpoint Forensics
easyAnalyze Linux disk image artifacts, including logs and Bash history, using FTK Imager to investigate insider threat activities and reconstruct user actions.

Operation QUICSILVER
Malware Analysis, Threat Intel
mediumInvestigate a targeted espionage intrusion from delivery through to command-and-control: unpack a disguised container, rebuild the payload hidden inside it, reverse the Go implant it drops, and turn the operator's leftovers into attribution.

Velociraptor Hunt - Rewind
Endpoint Forensics
mediumInvestigate a multi-stage intrusion across six workstations using Velociraptor, correlating artifacts to uncover how the attacker moved, escalated, and stole data before anyone noticed.

BPFDoor - StraitsTelecom
Endpoint Forensics
mediumInvestigate 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
mediumReconstruct 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.

MiniFast - UNC1549
Network Forensics
mediumAn aviation contractor's developer installed a database tool from the top search result. Reconstruct the full intrusion from a single capture, from the lure domain through the implant's tasking to the second stage pulled down in cleartext.

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?

Maromalix Nightmare
Threat Hunting
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.
