Cybercrime is one of the fastest-growing criminal phenomena with high damage potential: in 2021, 146,363 cybercrimes were recorded in Germany - over 12% more than in 2020, and a new record high. The financial damage amounted to 223.5 billion euros [1]. The new opportunities for crime arising from the surge in digitalization triggered by the coronavirus fell again slightly in 2022 owing to the lifting of the protective measures. However, the number of crimes committed abroad (i.e. the criminals were located outside the country) rose sharply compared to the previous year, making them more difficult to investigate and prosecute [2].
Numerous factors encourage online crime. The perpetrators respond flexibly to technical and social developments, and their actions are increasingly professional and global. Criminals are also able to operate from almost anywhere in the world and can easily cover their tracks.
Networking in society is growing dynamically in scale, and provides criminals with a steady stream of new opportunities. Growth of the Internet of Things (IoT) and Industry 4.0, in particular, provides cybercriminals with new gateways for attack [3]. Other drivers include the growing use of GPS technologies, central databases, wireless and mobile devices, networks and open-source software.
Artificial intelligence (AI) enables hackers to carry out their attacks more effectively and efficiently, and to detect vulnerabilities in program code. The AI-based ChatGPT chatbot, for example, is able to improve the quality of phishing attacks significantly [4]. Collection, storage and processing of vast quantities of information (big data) also presents criminals with attractive targets and makes such systems susceptible to attack [5]. By the same token, however, AI and big data can be used to enhance cybersecurity. For example, AI can be useful in detecting images and text that were themselves generated by AI. Big data can be used to identify suspicious network activity in real time [6].
The "hacker clause" adopted in Germany in 2007 in the form of StGB 202c, which criminalizes persons merely for searching for security vulnerabilities or programming or using tools suitable for this purpose, has had an adverse effect on IT security [7].
Careless handling of data exacerbates the security situation. Facilities for encrypting and signing emails, for example, are not used sufficiently often. Emails containing HTML code are easily forged and hidden content is easily added to them.
The likelihood of hacking attacks rises when personal data is disclosed too readily, or when apps are used that do not assure technical confidentiality. Criminals often encourage such behaviour by offering the prospect of rewards. Conversely, a positive development is that children and young people are becoming familiar with digital technologies and acquiring technical skills at an early age.
Companies that replace their in-house specialists with external service providers sacrifice the in-house expertise of their own staff and their familiarity with the company’s own IT systems. Options for better protection, such as the "principle of least privilege (PoLP)", are also often ignored.
