In mid-November we were granted another patent, this time<\/a> by the European Patent Office (EPO).<\/p>\n It bears the number EP3297221<\/a> and describes a \u201cTechnique For Detecting Suspicious Electronic Messages<\/a>\u201d. In concrete terms, the patent is about detecting electronic messages, such as emails, which are highly likely to have been sent in large volumes by means of a botnet.<\/p>\n To explain how this works in a short and simple way, emails received by a messaging server are given a time stamp, which is then stored in a database along with metadata about the sender and the contents. This can be used to compare with messages received later. If a large amount of emails are discovered to have simultaneously come from the same sender or have the identical content, it raises suspicion that the messages have been sent by a botnet and may well contain either spam or malware.<\/p>\n Enterprises interested in implementing the approach described above, are welcome to get in touch with Retarus<\/a> in this regard.<\/p>\n
