In addition to your proposal, offer advice of a paragraph or two to at least two other students. This proposal is for your term paper due in week 9. Research the web and find an appropriate incident related to either a successful or failed penetration testing effort, or a successful or unsuccessful hacking attempt against an organization, business or government facility. For the discussion lay out the basic details of the case, why you chose this case, and speculate on what specific lessons you learned from the case, as well as possible recommendations for future situations. This proposal should be no less than three or four paragraphs. (For those taking SEC420 concurrent with SEC435 this must be a different case study.)

Introduction and case selection. The WannaCry ransomware outbreak of May 2017 provides a compelling case study for cybersecurity students and professionals. It illustrates how offensive cyber capabilities—malware that self-propagates across networks—can cause widespread disruption when defensive practices lag. WannaCry exploited a vulnerability in the Windows Server Message Block (SMB) protocol, known as EternalBlue (CVE-2017-0144), for which a patch had existed since March 2017 but was not universally applied. This case was chosen because it foregrounds fundamental principles of defensive cybersecurity: timely patch management, network segmentation, robust backups, and rapid incident response. The vulnerability and patch timeline are well-documented in industry advisories and press reports (Microsoft Security Response Center, 2017; NIST, 2017; BBC News, 2017).

Case details and timeline. On May 12, 2017, WannaCry began to spread rapidly, encrypting files on infected Windows machines and demanding ransom payments in Bitcoin. The malware used a worm-like propagation mechanism that leveraged the EternalBlue vulnerability to move laterally across networks, allowing it to propagate swiftly within organizations that had exposed systems and unpatched hosts. The outbreak affected hundreds of thousands of computers across more than 150 countries, impacting sectors ranging from healthcare to logistics and manufacturing. The rapid spread highlighted the critical role of patch management and system hardening, as many affected systems ran older, unsupported Windows versions or had not applied the MS17-010 security update (Microsoft, 2017; NIST, 2017).

The "protagonists" in this case were the affected organizations and their incident response teams, who had to contain the spread, restore functionality, and recover data. A notable turning point in the outbreak was the unexpected discovery of a kill switch domain by a security researcher, which temporarily slowed the spread and bought time for remediation. This event underscored the importance of rapid threat intel sharing and coordinated response. Public authorities and industry researchers emphasized that patch deployment, disabling unnecessary services (such as SMBv1), and restoring from clean backups were the most effective mitigations in the immediate term (BBC News, 2017; MIT Technology Review, 2017).

What was done to remedy and restore operations. In the wake of WannaCry, organizations that had already deployed the MS17-010 patch and maintained current backups could contain the infection and recover with minimal data loss. Others, faced with unpatched hosts or systems that could not be patched immediately due to compatibility concerns, needed to isolate infected segments, disable SMBv1, and implement alternative security controls to prevent further spread. Microsoft released patches for supported and some legacy systems, while security vendors provided guidance on detection and remediation. In many cases, rapid incident response teams coordinated with national CERTs and internal IT organizations to segment networks, restore from offline backups, and reimagine recovery playbooks for future incidents (Microsoft, 2017; NCSC, 2017; Symantec, 2017).

Lessons learned and recommendations. The WannaCry episode reinforced several enduring lessons for cybersecurity practice. First, patch management is a cornerstone of defense; even when patches exist, timely deployment within an organization’s risk tolerance is essential to reduce window of exposure (Microsoft, 2017; NIST, 2017). Second, defense-in-depth strategies—such as network segmentation, disabling legacy protocols (like SMBv1), and restricting lateral movement—help limit the blast radius of a worm-like outbreak (NCSC, 2017; Fortinet, 2017). Third, robust backup strategies, including offline or immutable backups, enable rapid restoration with minimal ransom-related impact (Kaspersky, 2017; Symantec, 2017). Fourth, transparent and rapid incident response planning—encompassing containment, eradication, and recovery phases—facilitates faster recovery and reduces downtime (MIT Technology Review, 2017; BBC News, 2017). Finally, ongoing threat intelligence sharing and cross-sector collaboration are critical; the outbreak demonstrated how public-private coordination can accelerate detection, patch dissemination, and remediation efforts (BBC News, 2017; MIT Technology Review, 2017).

Applying these lessons to future incidents requires concrete operational steps. Organizations should implement a formal patch management policy with clear timelines, prioritize high-severity vulnerabilities, and automate deployment where feasible to minimize manual delays (Microsoft, 2017). They should disable insecure services and protocols, such as SMBv1, and enforce network segmentation to limit lateral movement (NCSC, 2017). Regular, tested backups stored offline or in immutable storage must be part of the standard operating procedure, with recovery drills conducted annually or after major changes in the IT environment (Fortinet, 2017; Symantec, 2017). Incident response plans should be exercised through tabletop exercises and live simulations, ensuring clear roles, escalation paths, and communication strategies are in place during an incident (MIT Technology Review, 2017). Organizations should also invest in endpoint detection and response (EDR) capabilities, continuous monitoring, and user awareness training to reduce the risk of phishing and other initial access techniques (Kaspersky, 2017; Fortinet, 2017).

In conclusion, the WannaCry incident demonstrates how a single unpatched vulnerability can cascade into a global disruption if defensive practices are not timely and comprehensive. By institutionalizing rigorous patch management, network hygiene, resilient backups, and proactive incident response, organizations can reduce exposure to similar attack patterns in the future. Building a culture of proactive security, continuous improvement, and cross-organizational collaboration is essential to turning a disruptive incident into a teachable, improvable process for safeguarding critical assets (UK NCSC, 2017; BBC News, 2017; MIT Technology Review, 2017).
