Viruses can replicate themselves on computer/phone systems, rendering them unusable. They accomplish this by attaching themselves to programs and files, where they remain undetected. This allows virus to spread across the entire system. They can be disguised in unsecure applications, music files, videos games, photos and toolbars.

The main purpose of hacking is to take information or cause financial damage to businesses. Hackers use a variety of methods like brute force encryption, polymorphic code, phishing and more to gain access to sensitive information. Once hackers have access to this information, they may sell it or create a botnet that launches attacks on other systems or users.

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

Another method by which hackers are stealing information is by attacking unsecured websites. This is done by exploit kits. Exploit kits are programs that scan a website for vulnerabilities and install malicious software on your device.

Make sure your operating system, software, and devices updated to prevent being targeted by hackers. These updates include security patches that fill in critical security holes that hackers are eager to exploit. Also, choose strong passwords. It is best to avoid using words from dictionary or personal information such as your birth date.
