In the recent years, one can observe the increase in the number of malicious software (malware) samples analyzed by the antivirus companies. One explanation is associated with attacker's antivirus systems hider tactic, which modifies hostile programs form, without changing it functionality. In effect, the first step of analysis is associated with the check if a given sample is a new threat or modification of existing. Very often such simple test can be performed automatically by dedicated information system. Paper describes information system, which allows dynamic analysis of malicious sample. Presented system was developed and deployed in the Institute of Computer Science, Warsaw University of Technology. During performed security research concerning ransomware threats system proves its usefulness. Additionally, the system become a knowledge base of known malware recently analyzed by our security team.

The article presents a prototype of a system for analyzing data from a honeypot network. A special attention is paid to finding similarities in the collected ssh sessions. The algorithm proposed looks for generalized patterns in the session using suffix trees. The patterns can be used for a convenient presentation of the displayed sessions and for searching. The examples of analysis carried out with the help of the algorithm are presented.

Security is one of the basic human needs. Due to the increasing citizens’ activity in the cyberspace, a need for security in this area is increasing. The cyber-threats may appear in many forms: from malware and phishing, to fraud or scams attempts. Rapid technological development makes the traditional methods of obtaining information insufficient for an automatic Web monitoring with the aim of detecting potential threats. The paper discusses the problem of monitoring of Web sources and indicates the existing gap between the volume of available information and the decision-making ability. Finally, it presents an example from the field of cyberspace security: Semantic Monitoring of Cyberspace project and achieved results.

Deep learning algorithms have achieved remarkable results in a wide range of tasks, including image classification, language translation, speech recognition, and cybersecurity. These algorithms can learn complex patterns and relationships from large amounts of data, making them highly effective for many applications. However, it is important to recognize that models built using deep learning are not fool proof and can be fooled by carefully crafted input samples. This paper presents the results of a study to explore the use of Generative Adversarial Networks (GANs) in cyber security. The results obtained confirm that GANs enable the generation of synthetic malware samples that can be used to mislead a classification model.

Purpose: The purpose of the article is to present both theoretical and practical basis for cybersecurity in electronic banking in Poland during the COVID-19 pandemic. During this period a major reorganisation of IT solutions occurred, which allowed to extend the range of online products and services offered both to bank customers and employees. As our life is more and more dependent on digital technologies, cyber attacks have become more costly and more dangerous. Driven by dynamic technological development regulations have changed, which resulted in cybersecurity becoming a key priority in financial institutions. All the more so because the rapid technological development has been followed by more and more advanced techniques used by criminals searching for easy financial profits. Methodology: The paper uses the method of literature review - mostly electronic sources,  descriptive and comparative analyses. Findings: From customers, perspective, the impact of COVID-19 pandemic on cybersecurity in electronic banking in Poland may be recognized as negative. The years 2020-2021 brought a dynamic growth in the number of digital banking customers, especially mobile banking. In those years financial institutions recorded  an enormous increase in online payments, which was the result of strong, forced by the pandemic, surge in sales in E-commerce. At the same time, there was a sharp rise in the crime rate targeted at banks, but most of all, at bank customers. While the security of the very financial institutions remained unthreatened, there was an explosion in the number of cybercrimes  targeted at E-banking users, with the losses giving dozens of millions PLN in total. That is reflected by the data provided by the National Bank of Poland, numerous complaints to the Financial Ombudsman, the Office of Competition and Consumer Protection, as well as the police investigations. Practical implications: The analysis of relations between theoretical and practical bases of cybersecurity in E-banking in Poland during the COVID-19 pandemic is a key factor for financial institutions. Cybercrime undermines customers' trust in E-channels and therefore negatively influences how banks are perceived, the level of the users' activity in digital channels, and consequently, activity and sales in E-channels. Besides the image and financial risks, banks need to take into consideration the increase in reputation, operation and legal risks. On these grounds, it is possible for state organisations and financial institutions to develop professional education concerning cybersecurity, not only for E-banking customers, but for the whole society.

Ilość zagrożeń teleinformatycznych w świecie wzrasta dynamicznie wraz z upowszechnianiem wykorzystania systemów komputerowych w kolejnych obszarach ludzkiej aktywności. Współczesne państwa w znacznym stopniu zależne są od szybkiego dostępu do informacji uwzględniając także ich przechowywanie, przetwarzanie oraz przesyłanie, co sprawia, że obszar ten stał się elementem gry geopolitycznej. Społeczeństwa oraz powoływane przez nie organy i instytucje powszechnie wspomagają się rozwiązaniami komputerowymi. Obecnie komputer zaliczany jest do typowego wyposażenia gospodarstw domowych. Należy do tego doliczyć także skomputeryzowane urządzenia zaliczane do szeroko rozumianej elektroniki użytkowej. Analogicznie w sferze publicznej komputery i urządzenia skomputeryzowane stały się powszechne. Zagrożenia teleinformatyczne, takie jak szkodliwe oprogramowanie, w tym wirusy i robaki komputerowe, jak również ataki DoS/DDoS, kradzieże, podmiana i uszkadzanie danych jak również celowe uszkodzenia systemów komputerowych należy współcześnie zaliczyć do katalogu metod i środków rywalizacji w środowisku międzynarodowym. Właściwymi dla nauk społecznych, w tym nauk o bezpieczeństwie metodami analizy i krytyki literatury przedmiotu, metodą historyczną i metodą obserwacyjną dokonano selekcji oraz analizy wydarzeń świadczących o wykorzystaniu szkodliwego oprogramowania w geopolityce w przeszłości. Wskazano przykłady wykorzystania poszczególnych zagrożeń teleinformatycznych w rywalizacji międzynarodowej. Omówiono przebieg i skutki zastosowania szkodliwego oprogramowania, ataków DoS/DDoS oraz kradzieży danych wskazując współczesne metody i środki zabezpieczania przed omawianymi zagrożeniami. Określono także zakres i potencjalne znaczenie zagrożeń teleinformatycznych w geopolityce w przyszłości.

he amount of IT threats in the world is growing dynamically with the spread of the use of computer systems in the subsequent areas of human activity. Modern countries depend on quick access to information, including its storage, processing and transmission, which makes this area an element of the geopolitical game. Societies, organisations and institutions commonly support themselves with computer solutions both in private life and in public space. Currently, the computer is included in typical household equipment. It should also be added to computerized devices classified as consumer electronics. Similarly, in the public sphere, computers and computerized devices have become commonplace. ICT threats, such as malware, including viruses and computer worms, as well as DoS / DDoS attacks, thefts, replacements and data corruption as well as deliberate damage to computer systems are nowadays considered to be part of catalog of methods and means of competition in the international environment. The selection and analysis of events demonstrating the use of malware in geopolitics in the past were appropriate for social sciences, including security studies, through methods of analysis and criticism of the literature of subject, historical method and observational method. The examples of the use of particular ICT threats in international competition are indicated. The course and effects of using malware, DoS / DDoS attacks and data theft are discussed, indicating contemporary methods and means of protection against these threats. The scope and potential significance of teleinformatic threats in geopolitics in the future was also defined
