Viruses are software programs that have the ability to replicate themselves in computer/phone systems and make them unable to perform. They do this by attaching to programs and files, where they are not detected. This allows viruses to infect the entire system. Viruses are most often hidden in unsecure applications like music, movies, photos, games that are free, and toolbars.
The main reason hackers hack is to obtain information or cause financial harm to businesses. Hackers employ many techniques to gain access sensitive information, including brute force attacks, encryption, polymorphic code and phishing. Once hackers have access to this information, they are able to sell it or create a botnet that launches attacks on other systems or users.
Certain viruses are specifically designed to steal passwords, personal data like dates of birth and passwords. These viruses are referred to as ransomware. Ransomware attacks are quite common and have affected major enterprises like the Colonial Pipeline (world’s largest beefpacker), JBS, and the Steamship Authority ferry service.
Another method that hackers use to taking information is by attacking unsecured websites. This is accomplished through exploit kits. Exploit kits are 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 hacked. These updates include security patches that fill in crucial holes that hackers love to exploit. Also, ensure that you use passwords that are secure. A good rule of thumb is to never use any word found in the dictionary, or any personal information like your date of birth.
