🔒Episode 15: “The Shadow Network”

Following the dramatic close of digital espionage in Episode 14, Episode 15 sees Jordan, the Chief Information Security Officer (CISO), alongside the Managed Security Service Provider (MSSP), confronting a new challenge: an endpoint within the network has been compromised due to the download of cracked software by an end user, a discovery made through vigilant analysis of Endpoint Detection and Response (EDR) logs by the MSSP.

📥 Act 1: Discovery of the Compromise

The episode begins with the MSSP team identifying suspicious activity in the EDR logs—specifically, an end user’s device communicating with a known command and control (C&C) server. This alarming behavior prompts an immediate investigation, revealing that the user had downloaded and installed cracked software, unwittingly planting malware that initiated the unauthorized communication.

🔍 Act 2: Tracing the Infection and Isolating the Threat

Jordan and the MSSP quickly trace the malware back to the illicit software installation. Recognizing the gravity of the situation, they isolate the compromised device to halt any further communication with the attacker’s C&C server and prevent the spread of the malware across the network. This decisive action stops the immediate threat in its tracks, but the incident exposes a critical vulnerability in the organization’s cybersecurity posture.

🛠️ Act 3: Remediation and Policy Implementation

With the immediate threat neutralized, attention turns to long-term mitigation strategies. Jordan and the MSSP collaborate to remove the malware from the compromised endpoint and conduct a thorough security audit to ensure no other devices are affected. Understanding the root cause of the breach—unauthorized software installation—they develop and implement a robust policy to prevent similar incidents. This policy includes technical controls to block unauthorized installations, enhanced monitoring for compliance, and comprehensive education for all employees about the risks associated with downloading and installing unapproved software.

🔜 Teaser for next episode “The BYOD Breach”

Episode 16, “The BYOD Breach,” will unravel how this policy, designed to boost productivity and flexibility, becomes a double-edged sword.
