Paper For Above instruction

The cyber incident selected for this analysis is the WannaCry ransomware attack, which emerged in May 2017 and rapidly spread across the globe, causing widespread disruption to organizations, governments, and individuals. Before commencing this report, our group held limited prior knowledge about this specific attack beyond some general awareness of ransomware threats and notable cyber incidents. This initial understanding served as a foundation for further research into the specific mechanics and repercussions of WannaCry.

The WannaCry attack was a sophisticated ransomware campaign that exploited a vulnerability in the Windows operating system, specifically leveraging a flaw in the Server Message Block (SMB) protocol. This vulnerability, known as EternalBlue, was reportedly developed by the U.S. National Security Agency (NSA) and later leaked by the hacking group known as The Shadow Brokers. Once the ransomware infected a system, it encrypted files and demanded ransom payments in Bitcoin for the decryption key. The attack propagated rapidly via network shares, enabling it to infect numerous systems within organizations in a short period.

The infection primarily affected computers running vulnerable versions of Microsoft Windows, including Windows XP, Windows 7, and Windows Server editions. Because of the widespread use of Windows across different sectors, the impact was extensive. Systems affected ranged from individual PCs to large enterprise servers, with many organizations unable to access critical data or resume normal operations. The attack primarily targeted institutions that had not applied the critical security patches issued by Microsoft prior to the outbreak, exemplifying the importance of timely software updates and cybersecurity hygiene.

The global impact of WannaCry was profound, affecting over 200,000 computers across 150 countries within days of its outbreak. The affected organizations spanned various sectors, including healthcare, telecommunications, transportation, and government agencies. Notably, the UK's National Health Service (NHS) experienced severe disruptions, with numerous hospitals unable to access patient records, schedule surgeries, or operate essential systems effectively. Similar disruptions were reported in laboratories, banks, and manufacturing firms worldwide, illustrating the attack's extensive reach and damaging consequences.

The attack resulted in significant operational impacts on organizations by causing system outages and service disruptions. Many healthcare providers had to cancel outpatient appointments and divert emergency cases, directly affecting patient care. Companies faced productivity losses, financial damages, and increased expenditure on IT recovery efforts. Moreover, the incident highlighted a critical vulnerability in legacy systems, which often lacked the latest security patches, making them attractive targets for cybercriminals. It also demonstrated the importance of cybersecurity awareness among employees, as phishing emails often serve as the initial vector for ransomware deployment.

Interestingly, the WannaCry attack revealed the extent to which state-sponsored hacking tools could be repurposed for cybercriminal activities. The exploit EternalBlue, allegedly developed by intelligence agencies, was used without authorization by cybercriminals to orchestrate widespread damage. The rapid development of a free decryptor tool by security researchers, which helped affected organizations recover data without paying ransom, underscored the importance of collaboration and information sharing in cybersecurity. Additionally, the incident prompted governments worldwide to review and enhance their cybersecurity policies and incident response strategies to better prepare for future attacks.
