Final answer:
A person intentionally sneaking into computer files with malicious intent is best described as a cybercriminal. The term encompasses the range of illicit activities aimed at breaching personal security online, which can include theft of personal information, harassment, and can extend to acts of cyber warfare.
Step-by-step explanation:
A person who sneaks into your computer files with bad intentions can be described by several terms, but the most appropriate choice from the given options would be cybercriminal. While hackers are often associated with breaking into systems, the term doesn't inherently imply bad intentions, as some hackers are ethical and help improve security. Crackers are akin to hackers but specifically focus on breaking encryption and security. Intruders may refer more generally to any unauthorized users but doesn't convey the specifically criminal aspect as strongly as cybercriminal.
With the increasing dependency on the internet for social connections, business, and information storage, the risk of being targeted by cybercriminals also rises. According to Pew Research Center, concerns over personal information security online have significantly increased. Cybercriminals utilize a variety of methods, such as inducing individuals to click on malicious links or extracting sensitive information, which can lead to harassment or theft of personal details like Social Security numbers.
Not only individuals but also governments and organizations are at risk, with some militant groups using cybercrime as a form of modern warfare to steal intelligence, disrupt communication, and spread disinformation. These activities highlight the critical importance of cybersecurity in today's interconnected world.
