Types of hacking
Financial crimes:
Data breaches and fraudulent activities are unfortunately widespread in today’s digital environment. Even though banks have taken precautions to protect their customers’ financial information online, cybercriminals still discover ways to steal it. The need of protecting one’s financial data is now well recognized.
One precaution you may take is to review your financial statements more frequently, such as your bank and credit card accounts. Because of this, keeping an eye out for symptoms of fraud in digital transactions and financial records is essential. If you want to be notified immediately of any suspicious behavior on your bank or credit card account, you can set up alerts.
A strong and unique password is essential for each of your financial accounts. Never share your passwords with anybody or use the same one for many accounts. To further protect your account, you can use two-factor authentication, which requires a code or biometric verification in addition to a password.
When making purchases online, it’s important to do it only on a secure server that won’t save your credit card information. See if the URL begins with “https” rather than “HTTP” and the lock symbol displays in the address bar. This ensures that your information is protected from hackers and other online threats.
Finally, stay on the alert for phishing tactics, which hackers use to try to trick you into giving them your personal information or money. Emails and pop-up windows posing as notifications from reputable companies, such as banks or credit card companies, are common vectors for this type of fraud. If you receive an email from someone you don’t know, delete it without opening the attachment.
Vandalism:
As a general term, “vandalism” refers to the willful destruction or damage of private or public property. Examples of vandalism include writing on walls, breaking windows, defacing buildings, and destroying playground equipment. Vandalism is punishable by a fine and maybe jail time.
Vandalism is a common way for people to show their discontent with authority figures or the status quo. Keep in mind, though, that vandalism is never a good solution to any issue. Innocent individuals and communities bear the brunt of the consequences.
Vandalism has a chilling effect on business activity as well. Fixing or replacing broken property is an unnecessary expenditure of resources that could be put to better use elsewhere.
Cooperation between civilians, groups, and law enforcement is essential for defeating vandalism. Parents and educators can help reduce vandalism by teaching children the importance of treating public and private property with respect, while communities can work together to clean up problem areas and install security cameras. Those who engage in vandalism may face legal consequences.
Hacktivism:
“Hacktivism” refers to the use of hacking and security techniques for computers in service of political or social causes. It’s a form of activism that encourages political or social change through the utilization of contemporary resources.
Hacktivists use a wide variety of tactics to achieve their goals, including website defacement, denial-of-service attacks, data breaches, and hacking into computer systems. Government agencies, multinational corporations, and other organizations they perceive to be unethical or antagonistic to their cause are common targets of their attacks.
Anonymous is one of the most well-known hacktivist groups, and it has carried out a number of high-profile attacks against government and corporate websites in the name of social justice and political freedom.
However, there is a polarizing aspect to hacktivism due to the unlawful nature of the activities it sometimes includes. Many people mistakenly identify hacktivism with acts of cyberterrorism.
Corporate espionage:
Corporate espionage refers to the illegal practice of stealing a company’s trade secrets or other confidential information for the purpose of competitive advantage. Information about a company’s inner workings, strategy, products, or services is obtained and utilized against it in this sort of economic espionage.
Corporate espionage can involve a wide variety of tactics, including theft, computer hacking, employee observation, and social engineering. Companies who fall prey to corporate espionage run the risk of losing a lot of money, having their reputation damaged, and maybe being taken to court.
Businesses can protect themselves from corporate espionage by instituting measures such as security audits, stringent password policies, employee training to spot and avoid social engineering attacks, and so on. Companies can improve their ability to detect and prevent cyber attacks by working with law enforcement and investing in cybersecurity technologies.
