Cambridge Analytica is the correct answer. The company was recently implicated in a global data theft crime that involved the unauthorized access and misuse of personal data from millions of Facebook users. Here is a detailed explanation of the answer:

Background Information on Cambridge Analytica:
Cambridge Analytica was a British political consulting firm that specialized in data analysis and targeted advertising. The company worked on various political campaigns, including the 2016 United States presidential election, during which it played a significant role in providing data-driven insights to political campaigns.

The Data Theft Crime:
In 2018, it was revealed that Cambridge Analytica had obtained personal data from approximately 87 million Facebook users without their consent. The data was collected through a third-party app called "This Is Your Digital Life," which was created by a researcher named Aleksandr Kogan. The app not only collected data from the participants who used it but also harvested data from their Facebook friends, resulting in a much larger pool of personal information.

Unauthorized Access and Misuse of Data:
Cambridge Analytica used this collected data to create psychographic profiles of users, which helped them target political advertising more effectively. The company claimed that they had deleted the data collected by the app, but it was later discovered that they still possessed a significant portion of it. This raised concerns about the potential misuse of personal information and its impact on privacy and democratic processes.

Global Fallout and Investigations:
The revelation of Cambridge Analytica's actions sparked a global outcry and led to investigations by various regulatory bodies, including the United States Federal Trade Commission and the United Kingdom Information Commissioner's Office. Facebook faced severe criticism for its handling of user data and its failure to protect the privacy of its users.

Legal Consequences and Closure of Cambridge Analytica:
As a result of the scandal, Cambridge Analytica faced legal consequences, including bankruptcy and dissolution. Several key individuals involved in the company, including its CEO Alexander Nix and whistleblower Christopher Wylie, testified before government committees and provided evidence of the company's practices.

Conclusion:
Cambridge Analytica's involvement in the global data theft crime, where personal data of millions of Facebook users was obtained without consent, led to significant repercussions and raised concerns about data privacy and ethics. The incident highlighted the need for stricter regulations and safeguards to protect personal information in the digital age.
