![]() In our analysis, we will use Angle by Derant, which is a SaaS platform that uses Suricata and Zeek. Zeek resembles Wireshark but works on a level higher – packet streams collected to connections instead of individual packets. Zeek will do general metadata extraction of network traffic and produce data about what is going on at connection level. Suricata will take a set of signatures of known bad indicators and produce alarms by matching the indicators to the network traffic. Two other tools that can be used for PCAP-file analysis but also for continued network monitoring are Suricata and Zeek. This will visualize which packets are contained in the PCAP-file. Wireshark is probably the most known desktop application. To analyze a PCAP-file a number of different tools can be used. Recorded network traffic is stored in a PCAP-file, also called a packet capture. The specific malware sample we will use in this article were collected originally by Palo Alto’s Unit42 Threat Intelligence and Security Consulting Team. It is an excellent site to find different types of malwares and the corresponding traffic. The network traffic sample has been downloaded from. In this article, we’ll examine what “bad” events show up in the network when the Emotet malware is executed in your systems. A large number of events happen in your systems every day.
