Nowadays, it can be said that in both the private and the business sector, all malware attempts to access your computer via e-mail. These are mostly so-called phishing mails, i.e. extremely well faked mails that are very credible. In the past they were often identified by their poor spelling. Nowadays, as a professional, I sometimes find it difficult to look at them and say at a glance that the mail is fake. Some of these refer to actually advertised vacancies and are sent to a company. When this reaches the application department and there is a Word file attached, which may contain the CV, everything looks safe at first. The receiving of such mails alone is not dangerous. But usually, if you open the document and then follow the steps in the document, two or three clicks are already too much. For example, a blackmailing Trojan has already been caught. This is a very common pest, for example. A Trojan that usually infects the computer using Windows and then encrypts files diligently in the background. This means that you no longer have access to your work documents, private photos are all encrypted. Then a ransom is extorted and if you don’t pay it, you won’t be able to access your files anymore. Basically, the blackmail is a good way to describe cybercrime at the moment. It is actually almost always about blackmail with private details. There are also mails that are circulating claiming “I filmed you consuming pornographic content”. Maybe everyone knows that, this was a big wave. And then it is claimed that the author has more personal data. This is then demonstrated with a password, which perhaps even belongs to you. This then comes from a password leak. But otherwise there is not much behind it. You really have to be careful with such mails! It’s best to delete such mails immediately, otherwise an infection can occur quite fast.
