This form of crime can both cause material damage, for example by sabotaging computer systems. It can also lead to violation of property rights, such as theft of source codes, customer data or other information. Additionally, it could affect a company's entire business systems. The most common data theft scenario is a hacker attack that penetrates a company's network. According to Antonucci (2017), data breaches occur daily in most places; Cyberattacks have exposed the growing vulnerabilities of personal information. Notably, additional tools used by government hackers have been released, making it easier to adopt sophisticated means of stealing corporate data, spreading malware or ransomware. There is no doubt that many companies often do not update their security vulnerabilities promptly. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”?

In ransomware cases, hackers demand money before unlocking files, which is becoming increasingly common. Examples of information and communications technology breaches in the 21st century include: the 2017 Wanna Cry attack, the 2014 eBay attack, the Yahoo Mail attack, and many more. Statistically, an analysis by an antivirus company found that ransomware payments reached more than $2 billion in 2017. Other analyzes suggest that compromised IT companies will exceed $10 billion in the next year. Therefore, this study highlights some common data breaches in recent history. DescriptionSpecifically, WannaCry ransomware is a worm that spread rapidly across various computer networks following May 2017. Following infection via Windows computers, the worm encrypts files on the computer's hard drive. , making it difficult for users to access files for fear of paying a ransom in terms of Bitcoins for decryption. Several factors contributed to the primary attack of the WannaCry virus as it hit various large and sophisticated systems such as the British National Health Service. Additionally, it revealed the Windows vulnerability believed to have been initially discovered by the NSA (United States Security Agency). The attack The ransomware started on May 12 and affected the computer systems and this type holds the computer hostage with data trapped inside although experts claim that it was the largest attack of its type. More than 200,000 computers were affected by this fast-spreading ransom attack, with hackers demanding $300 per computer. The attack crippled computer systems in at least 150 countries around the world, although experts predict that more similar attacks could occur in the near future. Who started this attack? Sometimes suspects remain anonymous pending investigation, but researchers affirm the connection. For the..
