Cyber attack protection

A cyberattack is any unauthorized action that targets computer information systems, computer networks, infrastructures, or personal computer devices. Cyber attacker is a person or process that attempts to access data, functions, or other restricted areas of the computer system without authorization, potentially with malicious intent.

In the modern world, the rate of development and change in technology is constantly accelerating. Including information technologies that bring a lot of useful things to people. They help automate routine processes in everything from cleaning the house to analyzing information for managing huge corporations. Often, all communication between people, both business and personal, goes into the virtual world. But this means that in this new information world the dangers are new and they are also constantly evolving. For example, cyberattacks that can ruin the life of any person or business.

Cyber attacks types:

Phishing

Phishing is an attack that mainly uses email, instant messengers or social media to trick people into downloading malware onto their devices or disclosing their data. Last year lots of organizations and users encountered phishing attacks.

Types of phishing:
spear-phishing - attacks aimed at specific people, for example, system administrators;
smishing - attacks that use text or SMS messages to attract the attention of the victim;
search engine phishing - attacks that use SEO to raise the sites the criminals need in the search results;
email phishing - email attack;
vishing - attack via voicemail.

Many phishing attacks use links and files that do not seem suspicious at first glance to deceive. Also, hackers use psychological tricks in the process of contact with the victim to get their way.

Ransomware

Ransomware is malware that blocks users' access to their software and requires them to pay a ransom. Usually ransomware is spread through spam or social engineering.

Next year, we expect to see more examples of encryption ransomware that encrypts the victim's files and then demands payment to get it back to work. It is important to remember that 42% of organizations that paid criminals never regain access to their files.

Malicious software

Malicious software stops devices or slows them down significantly. Spyware, viruses, worms, ransomware or Trojans are all used by cybercriminals. Malware reaches devices through malicious email attachments or file-sharing programs that distribute dangerous content disguised as music, videos or images.

Data leak

A data leak occurs when a user's confidential information becomes vulnerable. Many companies reported data breaches in 2020 and this trend is expected to continue in 2021.

DDoS attacks

DDoS attacks occur when an attacker directs a large amount of traffic to a system or server, forcing it to stop or suspend.

Man-in-the-middle (MitM)

Man-in-the-middle (MitM) or middleman attacks occur when an attacker intercepts and modifies information in transit. An example would be a fake Wi-Fi hotspot that looks and works like a real one, but intercepts your information. With the growing trend of telecommuting and digital communications, it is becoming increasingly important for companies to use end-to-end encryption in data exchange for example messaging or videoconferensions.

Other types of attacks that hackers may also be actively using in the next year:

SQL injection - obtaining unauthorized access to information using a structured query language;

zero-day exploits - quickly exploit security flaws for new software versions;

Brute-force attacks (Brute force) - cracking a password by enumerating all possible key options;

DNS tunneling - making domain name systems a weapon for hackers.
