A 2014 report sponsored by McAfee estimated that cybercrime had resulted in 445billionUSDinannualdamagetotheglobaleconomy.Approximately1.5 billion was lost in 2012 to online credit and debit card fraud in the US. In 2018, a study by the Center for Strategic and International Studies (CSIS), in partnership with McAfee, concluded that nearly 1 percent of global gross domestic product (GDP), close to $600 billion, is lost to cybercrime each year. The World Economic Forum 2020 Global Risk Report confirmed that organized cybercrime groups are joining forces to commit criminal activities online, while estimating the likelihood of their detection and prosecution to be less than 1 percent in the US. There are also many privacy concerns surrounding cybercrime when confidential information is intercepted or disclosed, legally or otherwise.
Computer crime encompasses a broad range of activities, including computer fraud, financial crimes, scams, cybersex trafficking, and ad fraud.
