500 Wordsafter Doing Some Research On The More Notorious Virus Worm

After doing some research on the more notorious virus, worm, or spyware attacks in the last few years, choose one and post a brief one paragraph summary discussing: (a) the name of the malware and category (virus, worm, etc.) (b) target operating system (c) the malware's tactic for infecting a victim PC (d) effect on an infected system (e) how many computers were infected over what time period (f) malware author, if known, and whether s/he was ever apprehended and successfully prosecuted.

Paper For Above instruction

One of the most notorious malware attacks in recent years is WannaCry, a ransomware worm that emerged in May 2017. WannaCry is classified as a computer worm and ransomware, which encrypts victims’ files and demands payment in Bitcoin for their release. The malware primarily targeted Windows operating systems, exploiting a vulnerability in the Windows Server Message Block (SMB) protocol known as EternalBlue, which was believed to have been developed by the U.S. National Security Agency (NSA) and leaked by the Shadow Brokers hacking group. The infection process involved the worm scanning random IP addresses for vulnerable Windows machines, then rapidly propagating by exploiting the SMB vulnerability to infect connected systems without user interaction. Once infected, systems experienced their files being encrypted with RSA+AES encryption, rendering data inaccessible and prompting a ransom message demanding payment for decryption keys. The attack had devastating consequences, affecting over 200,000 computers across 150 countries within a few days of outbreak, impacting sectors such as healthcare, finance, and government. Notably, the UK's National Health Service (NHS) was severely affected, with many hospitals forced to cancel appointments and divert emergency patients. The creators of WannaCry remained largely anonymous, with no confirmed identification or prosecution of the malware's authors as of today. While some researchers speculated that the hackers behind WannaCry might be linked to North Korea, known as Lazarus Group, no definitive evidence has been publicly presented linking the threat to any nation-state or individual, and the authors have not been apprehended or prosecuted. This attack highlighted the importance of timely software updates and robust cybersecurity measures, as many affected systems had not applied available patches, leaving them vulnerable. The widespread impact of WannaCry demonstrated how malware can rapidly exploit vulnerabilities on a global scale, causing significant economic and societal disruption. It also underscored ongoing challenges in tracking cybercriminal groups and bringing them to justice, emphasizing the need for international cooperation in cybersecurity law enforcement and prevention efforts.
