More than 30% of computers are infected by viruses created by hackers. Hackers breach systems for a variety of reasons such as stealing information, harming others, or disrupting networks. Modern technology allows hackers to work remotely from anywhere in the world. Key problems caused by hackers include crippling government systems through prolonged probing to find weaknesses, creating viruses that damage computers and leave backdoors, and organized hacking groups that are difficult for experts to counter. While there are no permanent solutions, methods to prevent hacking include using hackers' own tools to strengthen defenses, increasing cybersecurity funding, and reformatting infected systems. The outlook on preventing widespread hacking is pessimistic as hackers continue to innovate faster than defenses.
