Viruses can replicate themselves on computer/phone systems, making them inoperable. They accomplish this by attaching themselves to files and programs where they remain undetected. This allows viruses to spread through the entire system. Most viruses are concealed within unsecure applications like music, movies, images, free games and toolbars.

The main purpose of hacking is to get information from a victim or cause financial harm to businesses. Hackers employ a variety methods like brute force encryption, polymorphic coding, the phishing technique and many more to gain access to sensitive information. Once this information is obtained, hackers may sell it or use it to create a botnet that can be used to attack other systems or users.

Certain viruses are specifically designed to steal passwords, personal data like dates of birth and passwords. These viruses are known as ransomware. Ransomware attacks are frequent and have even impacted major companies such as the Colonial Pipeline, JBS (world’s largest meatpacker), and the Steamship Authority ferry company.

Hackers also have the ability to steal information by attacking unprotected websites. This is done using exploit kits. Exploit kits are software programs that look over websites for vulnerabilities, and then install malicious code on your device.

Make sure your operating system, applications, and devices up to date to avoid being hacked. These updates include crucial security patches that plug holes that hackers love exploiting. Also, choose strong passwords. A good rule of thumb is to not use any word that is found in the dictionary or any personal information such as your date of birth.
