Many attacks are successful because users do not identify them as such. Particularly in the context of phishing, for example, emails from unknown senders should always get attention. In such emails, you should absolutely refrain from saving or opening attachments or clicking on links. One should surf the web with the same degree of caution: here, too, threats can lurk on supposedly harmless websites. Therefore, do not download any software from websites that you cannot trust. The absence of SSL certificates is a good clue here.
System administrators and webmasters also have other ways to detect cyberattacks. Servers log events in log files in standard. Dangerous activities can also be traced in the latter. For example, an increase in failed attempts to enter the password suggests a brute force attack.
In addition, one should monitor one’s own IT infrastructure. Malware often comes with side effects. If the connection to the system or network is slower than usual, it could be a sign that a cyberattack is in progress. However, the reverse does not work: fully operational computers can still be infected with malware.
