Here are some of the reasons computer hackers break into devices:

• Financial crimes. We’ve all heard the classic story of somebody checking their credit card statement, only to find transactions they didn’t make. These false transactions are often the result of computer hackers stealing your credit card numbers, checking account info or gaining access to other financial data.
• Vandalism. Hacking has its own subculture, so some hackers may want to vandalize certain websites just to show off to other hackers. Does it sound ridiculous? Don’t make the mistake of not taking this motivation seriously; it’s fairly common, according to Malwarebytes.
• Hacktivism. This portmanteau describes a form of hacking somewhat like vandalism. Some hackers may want to alter or destroy certain websites for politically motivated reasons.
• Corporate espionage. Spying existed long before the internet era, and hacking has only made espionage more accessible to the everyday person. With much of the world constantly connected to the internet, one company can hack into other companies’ devices to steal their information and use it to build an unfair competitive advantage.
