Leveraging MITRE Shield to Defend Against Ransomware
Written by: Joseph R. Salazar, CISSP, CEH, EnCE – Ransomware attacks have evolved and grown in number. Traditional ransomware sought to spread and encrypt as many endpoints as possible, but Ransomware 2.0 attacks employ advanced methods or have a human controller directing their activities. These attacks spend much more time conducting discovery to identify business-critical assets for encryption. Because these assets are essential for business continuity and daily operations, the organization is more likely to pay to recover them instead of spending the money on endpoint systems they could re-image and recover. Attackers encrypting the entire Active Directory server infrastructure can demand much higher ransoms, and the organization must pay or else lose money, time, and resource attempting to restore operations. Additionally, these attackers often exfiltrate data and threaten to release it to induce ransom payment, often demanding a second ransom to prevent the release of the information.
