Viruses can replicate themselves on phone and computer systems, making them inoperable. They do this by attaching to files and programs where they are undetected. This allows virus to infect the entire system. They can be disguised in unsecure applications such as music files, videos, photos, games, and toolbars.

Hacking is used primarily for stealing data or to cause financial harm to businesses. Hackers employ a variety of methods like brute force encryption, polymorphic code, phishing and more to gain access to sensitive information. Once hackers have this information, they are able to sell it or create a botnet that launches attacks on other systems or users.

Certain viruses are designed to take passwords and personal information such as dates of birth. These viruses are known as ransomware. Ransomware attacks have become frequent and have impacted major companies such as the Colonial Pipeline (world’s largest beefpacker), JBS, and the Steamship Authority ferry service.

Hackers also have the ability to steal information by attacking unprotected websites. This is done through exploit kits. Exploit kits are software programs that automatically scan a website for vulnerabilities, and then install malicious software on your device, without you even knowing that it has happened.

Keep your operating system, applications and devices updated to prevent being targeted by hackers. These updates contain critical security patches that close security holes that hackers love exploiting. Also, be sure to use passwords that are secure. It is best to not use words from dictionaries or personal data such as your birth date.
