In an increasingly digitalized world, cyber threats are playing an ever greater role. The pandemic and working at home also favor these threats. In the last two years, the number of cyber attacks has increased sharply. This is also confirmed by a study by EY (german only). The human factor plays a major role in this context. But what if the threat itself comes from within the company’s own ranks? So-called insider threats are often underestimated by many companies and organizations. Yet the effects of such a threat can be devastating. Read the rest of this entry »

E-mails are a major gateway for cyberattacks. These attacks are no longer isolated incidents and are part of our everyday life. Especially the spreading of malware through attached documents with macros are very popular among cyber criminals. These macros can for example contain hidden malware. If the recipient activates these macros when opening the document, any malicious software they may contain can cause great damage. For this reason, a protection mechanism for e-mail macro filtering was installed for the RWTH e-mail service on November 16, 2021. Office documents are the most used, but also PDFs, e.g. containing form fields. Read the rest of this entry »

Database systems are essential in many aspects. They allow large amounts of data to be organized, read and stored for the long term. The field of application of database systems is vast and so is the amount of personal data stored in them. For example, banks and insurance companies use databases to structure and store account information and information relating to accounting transactions. Every time we search for a product in a web store, we access a specific database, and our user data, such as login information, is also stored in databases. At best, these sensitive data are encrypted. The effort required to build and maintain these electronic databases is great – but the biggest challenge is to ensure their security. One of the greatest threats to these databases and the data they contain are so-called code injections. Read the rest of this entry »

Vishing: Stealing data on the phone

Cyber-attacks are not just part of everyday life in companies. Even when opening our private e-mail inboxes, we occasionally encounter peculiar e-mails suggesting that the addressee is required to take urgent action. The e-mail urges the addressee to update personal data, enter account information for the payout of a reward, or click on links. Phishing is no longer unknown among fraud methods. However, the attacks are becoming more and more elaborate. Somewhat less known and therefore more surprising, however, are so-called vishing attacks. Fraudsters are coming up with a lot of new ways to obtain data from their victims. Read the rest of this entry »

The number of smart technologies seeing the light of day is growing steadily. Any everyday problem either gets its own smart solution or becomes at least supported by new technologies. The Internet is all around and supports us in every single aspect of our lives. By now, even our coffee machines are connected to our smartphone and ensures that our coffee is already waiting for us in the kitchen while we are still sitting at our desk. The so-called Internet of Things has countless advantages and is rightly referred to as the 4th Industrial Revolution. What exactly lies behind this term, what are the risks, and how can we avoid them? Read the rest of this entry »

We support the Safer Internet Day. Do you? (Source:

How safe is our use of the Internet? That is not an easy question to answer. Some risks we are aware of, but others are often completely underestimated. Whether one’s own use of the Internet is really safe is usually only noticed, if at all, when it is already too late. Therefore, it is particularly important to raise awareness of the risks and emerging concerns about using the Internet. From cyberbullying to social media use or digital identity, every year the international Safer Internet Day (SID) aims to raise awareness about Internet safety. Read the rest of this entry »

Backdoors: Access Through an Alternative Access Point

Unnoticed access through the backdoor can be particularly tricky. (Source:

In life, sometimes it can be very useful to have a plan B or to keep a backdoor open. But would you leave your house and hide the keys to the backdoor under the doormat? For burglars, this setup would probably be an easy target. In IT as well, so-called backdoors are a very popular target for hackers. However, these backdoors are much more tricky and discreet than an open door or hidden keys under a doormat. Because even when the original breach of security, such as an open window, no longer exists, cybercriminals can still get in and out as they please via the implemented backdoor.
