Open a suspicious link received to your mailbox? Forgot to update the system? Not using two -factor authentication? You are at risk! However, there is no reason to panic. Let’s take a look at the five most popular hacker attacks and ways to protect against those attacks.

1. Viruses (Ransomware Viruses)

Viruses are usually called malicious software that infects a computer or other computing device when a user opens an email attachment or follows a link to a malicious website. A ransomware virus is a specialized virus that encrypts all files in the system and does not provide user data until a ransom is paid. To reduce the chances of infection with similar viruses, you need to be vigilant and learn to recognize suspicious files and questionable requests. In addition, you must use security software, for example, solutions from or from any other specialized forum.

2. Potentially Unwanted Programs (PUP)

Programs that may be unwanted are trojans, spyware or adware. It is usually installed along with other useful programs that the user decides to download. Such programs can secretly record all keystrokes, scan files on your hard drive and read browser cookies. To protect against these threats, do not download or install applications, browser extensions, or other programs from untrusted websites. In addition, you should provide a permanent backup of the contents of the device to an external disk or an online backup service.

3. Phishing

Phishing is a form of hacking with the help of email, where users try to trick and force users to transfer logins and passwords or other important information. Using email protection software for Internet privacy will help detect suspicious links and block spam and messages with malicious attachments, and multi-factor authentication helps protect your account, even if the password has been stolen.

4. An Acc Hack

Hackers can gain access to user accounts using “forward attacks”, when special programs go through various login and password options – usually using dictionaries and other passwords that were stolen earlier. To prevent this from happening, you will need to use a VPN service and block login to your account after certain login attempts. You can also protect yourself from automated login attempts using tests that differentiate someone from a robot, for example, reCAPTCHA.

5. Long-Updated or Outdated Software

Hackers can exploit vulnerabilities in system software and web applications to execute unauthorized code, gain access to systems or steal information. We can recall the example of Equifax – they had installed the Apache Struts web framework, which was not updated in time. This led to the outrage of 143 million social security numbers (in the US this is an important taxpayer identification mark), addresses, driver’s license numbers and credit cards.
