How do you reconstruct an attack spread across six workstations? The evidence tells a story of compromise, lateral movement, privilege escalation, and data theft. Velociraptor Hunt – Rewind puts you in the investigator’s seat. With no SIEM available, examine evidence gathered by an offline collector and correlate artifacts in Velociraptor to reconstruct the intrusion. Where did it start And how far did it spread? Take the challenge: cyberdefenders.org/blueteam-… #CyberDefenders #CyberRange #EndpointForensics #DFIR #ThreatHunting #BlueTeam

What if the attacker's C2 was hiding inside your calendar? DeadDrop - Hollow is now live on CyberDefenders. Trace the attack from phishing to domain compromise and a covert Microsoft 365 C2 channel. Can you piece together what happened? cyberdefenders.org/blueteam-… #CyberDefenders #CyberRange #ThreatHunting #DFIR #BlueTeam

How do you find a backdoor that never opens a port? BPFDoor - StraitsTelecom is now live on CyberDefenders. Follow the attack from stolen credentials through persistence, privilege escalation, lateral movement, and encrypted data exfiltration. Can you piece together the full attack chain? cyberdefenders.org/blueteam-… #CyberDefenders #CyberRange #EndpointForensics #DFIR #ThreatHunting #BlueTeam

How does one exploited server turn into a domain-wide ransomware attack? ActiveMQ - LockBit Ransomware is now live on CyberDefenders. Can you piece together the full attack chain? cyberdefenders.org/blueteam-… #CyberDefenders #CyberRange #ThreatHunting #DFIR #Ransomware #BlueTeam

The breach started with someone else. Then it reached his machine. A senior engineer at Wowza Enterprise was compromised. Then Johnny Tronus, a data scientist on the marketing team, remembered a file he had recently downloaded from an email exchange with that engineer. His VM was captured before the attacker could cover their tracks. CodeFreeze 2 is now live on CyberDefenders. Can you reconstruct the attack from the first compromise to the cyberdefenders.org/blueteam-… #CyberDefenders #DFIR #DigitalForensics #IncidentResponse #ThreatHunting #BlueTeam #CyberRange

The ransomware was only the beginning. The breach started much earlier. A leaked VPN configuration gave an attacker a way into Ancientland Investment Advisory. From there, the attack moved through the network, compromised credentials, escalated privileges, and ended with ransomware deployed across the domain. Ancientland Breach - LockBit is now live on CyberDefenders. 🧨 Can you reconstruct every move the attacker made? cyberdefenders.org/blueteam-… #CyberDefenders #DFIR #DigitalForensics #IncidentResponse #ThreatHunting #Ransomware #CyberSecurity #CyberRange

Would you trust the installer? That is where the investigation begins. A routine workstation setup led to a destructive compromise. Somewhere between the search, the download, and the execution, the attacker gained control. Phantom Installer is now live on CyberDefenders. The attacker wanted the evidence gone. Can you find what they missed? cyberdefenders.org/blueteam-… #CyberDefenders #EndpointForensics #DFIR #ThreatHunting #DigitalForensics #BlueTeam #CyberRange

The download looked legitimate. The traffic told a different story. A developer workstation downloads what appears to be a legitimate database tool. Soon after, it begins making periodic connections to an unfamiliar external IP. MiniFast - UNC1549 is now live on CyberDefenders. Analyze the PCAP and browser memory dump to reconstruct the attack, trace the C2, uncover what the attacker accessed, and determine whether data was stolen. Can you turn the traffic into a complete attack story? cyberdefenders.org/blueteam-… #CyberDefenders #NetworkForensics #DFIR #ThreatHunting #SOC #CyberSecurity #CyberRange

Someone knew what they shouldn’t have known. Privileged case strategy was exposed. Confidential documents were stolen. And the first clue looked like an ordinary conversation. Now it’s your job to reconstruct the attack, from initial access and credential theft to persistence, discovery, encrypted communications, and data theft. Crossed Signals is now live on CyberDefenders. Dig through forensic artifacts. Connect the evidence. Recover what the attacker tried to hide. Ready to find the signal in the noise? cyberdefenders.org/blueteam-… #CyberDefenders #DFIR #DigitalForensics #BlueTeam #IncidentResponse #CyberSecurity #EndpointForensics

The build passed. Every test was green. The backdoor shipped to production anyway. Poisoned Pipeline is now live on CyberDefenders. Trace the attack from a poisoned npm dependency through CI/CD and into AWS, using evidence from Splunk, disk images, and Git history. No single source tells the whole story. Can you stitch the full attack chain together? cyberdefenders.org/blueteam-… #CyberDefenders #ThreatHunting #SupplyChainSecurity #DFIR #CyberSecurity

The difference between a SOC that catches attackers early and one that discovers breaches weeks later? Triage discipline. Our comprehensive SOC alert triage guide covers the complete 7-stage workflow, common failure points that break even well-designed processes, and how to build triage as a career skill, not just a daily task. 💻 📖 Read the full article: f.mtr.cool/opfqvvxajg #CyberDefenders #SOC #Cybersecurity #AlertTriage

🆕 New lab: CodeFreeze 📚 Category: Endpoint Forensics The Threat Intelligence team flagged it first, credentials and API keys for sale on a dark web marketplace. But who breached Caspery's machine? How did they get in? What did they take beyond the obvious? Investigate the breach → f.mtr.cool/qklbdfsnqk #CyberDefenders #SOC #DigitalForensic

Advanced persistent threat actors routinely spend weeks, sometimes months, inside a network before triggering a single high-confidence alert. They're not moving fast. They're moving deliberately. 🔇 Our latest blog goes deep on exactly this, and gives SOC analysts a practical framework for shifting from point-in-time alert response to longitudinal behavioral detection. 🕵️ 📖 Read the full article to stop it: f.mtr.cool/grghhrkkcx #CyberDefenders #SOC #Cybersecurity #ThreatHunting

Want to level up as a SOC analyst? Stop waiting for experience to come to you; go get it.  🕵️ We just published a practical case study on one of the most common and damaging attack types hitting organizations right now: Microsoft 365 Business Email Compromise. 📧 Stop reading theory. Start practicing with real-world scenarios. 💻 🔗 Read the full case study now → f.mtr.cool/aemubivipu #CyberDefenders #CloudSecurity #SOC #Cybersecurity

Attackers don’t behave the same way in theory vs reality. 🕵️ Honeypots expose the difference. From: - Initial access attempts. - Credential abuse. - Lateral movement patterns. You get actual attacker behavior… not assumptions. 🔍 That’s gold for tuning detections in a SOC.  👉 Check the full guide: f.mtr.cool/ydrurcrqjk #CyberDefenders #SOC #Honeypot #Cybersecurity

AWS IAM is where security is won or lost.  If a role can: 🔹 sts: AssumeRole broadly.  🔹 Access * resources. 🔹 Skip MFA conditions. You’ve basically handed attackers lateral movement in the cloud. ☁️ Least privilege in AWS is not optional… It’s survival.  👉 Check the Full AWS Guide: f.mtr.cool/gybrnexphx #CyberDefenders #AWS #SOC #DFIR #Cybersecurity

Your CSPM covers your cloud. Your EDR covers your endpoints.🔐 Neither covers your developers' IDE plugin ecosystem. 🧑‍💻 CursorJack Lab is a hands-on scenario built around exactly that blind spot, an MCP-based compromise of a Cursor IDE install leading to multi-region cloud takeover and on-chain exfiltration.  👉 Investigate Now: f.mtr.cool/rewupuiowj #CloudSecurity #DetectionEngineering #MCP #DevSecOps
