How Cyber Attacks Work


A cyberattack is a malicious and deliberate attempt by an individual or organization to breach the information system of another individual or organization. Usually, the attacker seeks some type of benefit from disrupting the victim’s network.

How often do cyber attacks occur?

Cyberattacks hit businesses every day. Former Cisco CEO John Chambers once said, “There are two types of companies: those that have been hacked, and those who don’t yet know they have been hacked.” According to the Cisco Annual Cybersecurity Report, the total volume of events has increased almost fourfold between January 2016 and October 2017.

Why do people launch cyber attacks?

Cybercrime has increased every year as people try to benefit from vulnerable business systems. Often, attackers are looking for ransom: 53 percent of cyber attacks resulted in damages of $500,000 or more.
Cyberthreats can also be launched with ulterior motives. Some attackers look to obliterate systems and data as a form of “hacktivism.”

What is a botnet?

A botnet is a network of devices that has been infected with malicious software, such as a virus. Attackers can control a botnet as a group without the owner’s knowledge with the goal of increasing the magnitude of their attacks. Often, a botnet is used to overwhelm systems in a distributed-denial-of-service attack (DDoS) attack.

Telecom Industry as an Opportunity for a Successful Career

The faculties related to IT and telecommunications attract many talented students to Polish universities who want to explore their knowledge in this field. However, this is not surprising, because there are many companies and enterprises on the market offering numerous internships and programs. This is a great opportunity to develop and gain valuable experience in the first stages of building your own professional career. The number of positions to be filled in the telecommunications industry is still growing. The dynamics of this industry is huge. Currently, implementation of 5G technology is underway in many places in Europe, which will significantly improve data transmission. This necessitates the employment of thousands of people who will speed up the process. However, there is no shortage of work on other projects. Data analysis specialists, mobile application programmers and infrastructure specialists have constantly sought after. These are just some of the offers, attract

What Is threat intelligence?

The concept of intelligence isn’t anything new. It’s been used throughout history and in many different industries; we see it in  OSINT , espionage and even market research, among others. Threat intelligence, specifically, is collecting and analyzing information about indicators of past, current and future cyber threats, which enables an organization to take action to protect their assets, network and the entire organization. The keyword here is analysis. Let’s think of it this way: You’ve compiled a list of all the data breaches that took place over the past year and the types of malware that caused them. That list may be informative, but it doesn’t do much good by merely existing. So what now? You have to combine your historical knowledge with data on current threats, attack vectors, existing and exploited vulnerabilities, threat actors that are specific to your industry, then analyze and compare them to find the needle in the haystack that will yield the relevant intel that

Is Connectivity Making Industrial Cybersecurity More Vulnerable?

It can be argued that industrial facilities have taken to digital transformation much earlier than other enterprises. While it’s only now that some businesses are committing to adopting digital tools, factories have been using robots and programmable logic controllers (PLCs) decades before the dotcom boom of the nineties. Industrial cybersecurity comes to the forefront as industries increasingly adopt digital technologies. What’s probably sweeping industries today are technologies that rely on connectivity: the cloud, mobile computing, and the  Internet-of-Things  (IoT). These technologies offer some very exciting applications. The cloud has allowed organizations to shift part of their IT infrastructure off-premises and easily scale their available computing resources. Mobile computing and connectivity have allowed engineers to monitor and control their machines remotely. Sensors and robots are now even smarter, and through the IoT, are capable of interfacing with external artific
