In this article, we’ll explain exactly how this method works and how you can protect yourself from it. Read the rest of this entry »
E-Mail Attachments and Their Challenges

Everybody has experienced this: You are working on documents with several people. When the work statuses then need to be exchanged, there are various approaches.
Still popular is the sending of attachments via e-mail. Sounds easy, but it can cause some difficulties.
To support you at this point, the IT Center has prepared a handout on how to deal with attachments. But let’s start from the beginning…
E-Mail Security – E-Mail & Mail Statistics at RWTH

About 50 years ago, the first e-mail was sent – albeit between two computer systems that were part of the same local network. In the 1980s, the internet was opened up to a larger circle of users and e-mail was given its own transmission protocol “Simple Mail Transfer Protocol” (SMTP).
Even today, the exchange of messages via e-mail is undoubtedly an important way of exchanging information between parties via an asynchronous communication channel.
Before the Audit is After the Audit

In many fields, audits are part of everyday work. As soon as management systems are to be implemented, further developed or certified, one is inevitably confronted with this term. We previously reported on our last audit and our associated (re-)certification here at the blog as well. But what are audits exactly, why do they exist and how are they carried out? In our article, we will explain in detail what they are all about. Read the rest of this entry »
Insider Threat: The Threat from Within

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 »

Macros – E-mail Filtering at RWTH

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 »
SQL Injection: Databases Attacks

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 »
