Viruses can replicate themselves on computer/phone systems, rendering them inoperable. They do this by attaching to files and programs where they are not spotted. This allows the virus to spread throughout the entire system. Viruses can be hidden in unsecure apps such as music files, videos, photos, games, and toolbars.

The main goal of hacking is to steal information or cause financial damage to businesses. Hackers employ a variety of techniques, such as brute force encryption, polymorphic code, hacking, and more to gain access to sensitive information. Once hackers have the information, they can either sell it or create a botnet that launches attacks on other systems or users.

Some viruses are designed to steal passwords and personal information like birth dates. These types of viruses are known as ransomware. Ransomware attacks are quite common and have even impacted large enterprises like the Colonial Pipeline, JBS (world’s largest meatpacker) and the Steamship Authority ferry company.

Another method that hackers use to taking information is by attacking websites that aren’t secure. They can accomplish this by using a technique known as exploit kits. Exploit kits are software programs that check websites for vulnerabilities, and then install malicious software on your device.

Make sure that your operating system, applications, and devices updated to avoid being targeted by hackers. These updates include crucial security patches that plug the security holes hackers love to exploit. Also, make sure you choose passwords that are secure. 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.
