“Great Product! I evaluated Hornetsecurity while I was at my last job. One of the first things I did when I started my current job was to implement Spiceworks Cloud based Help Desk and switch to Hornetsecurity for spam and malware filtering. My users love both and so do I. I would recommend Hornetsecurity to anyone looking for a spam/malware filtering service provider.”

Email Conversation Thread Hijacking

Email Conversation Thread Hijacking

You should only open email attachments and links from senders you know is an advice often given when it comes to preventing email-based malware and phishing attacks. However, in this article we outline an attack technique called email conversation thread hijacking, which uses victim’s existing email conversations and thus trust-relationships to spread to new victims. Against this attack the previous advice will not help. We explain how email conversation thread hijacking is used by attackers, and why it dramatically increases the likelihood for victims to open malicious links or malicious attachments.
Emotet Update increases Downloads

Emotet Update increases Downloads

The Hornetsecurity Security Lab observed a 1000 % increase in downloads of the Emotet loader. The increase in Emotet loader downloads correlates with Emotet’s packer change, which causes the Emotet loader to be less detected by AV software. Our gathered data suggests that the increase in Emotet loader downloads stems from the loader being detected less and thus also the Emotet loader download URLs being blocked less by security mechanisms. Our data, however, also suggests that AV vendors are already closing the detection gap and the detection of the Emotet loader should increase again and thus the number of downloads decreasing again. This analysis is a good display of the impact of the changes to the Emotet loader’s packer.
