Illumio’s Michael Adjei analyzes three real-world cyber attack case studies to demonstrate how detection failures and limited network visibility allow threats to spread rapidly across enterprise systems.

Key Points

• Michael Adjei details a Microsoft Teams-themed phishing scam, an identity-based payment fraud case, and a sophisticated long-term threat campaign.
• Attackers utilized memory-based malware, compromised partner email accounts, and steganography to hide malicious commands within image files.
• Common security failures included ineffective email filtering, insufficient user awareness, and a lack of visibility into lateral east-west network movement.
• The analysis emphasizes that extended dwell times are primarily caused by missed monitoring signals and gaps in internal security infrastructure.

Why it Matters

These case studies highlight the critical need for organizations to prioritize early detection and network segmentation to contain breaches before they escalate. By addressing visibility gaps, businesses can significantly reduce the potential damage caused by sophisticated threats that bypass traditional perimeter defenses.
