Identifying antimalware signature
Today's post will explain a simple method that allows you to identify a specific fragment of a binary file that your antimalware finds suspicious. This whole idea was born when I tried to download slammer.pcap file, with idea to see what this worm did with DCE RPC calls. As soon as I tried to download the file from SampleCaptures - The Wireshark Wiki , my Endpoint Security agent triggered the alarm and deleted the file before it was written to the filesystem (and after it was downloaded). Note that this was no executable file format, the trigger was based on the inspection of a network capture (.pcap) file format. The first thing I intended to do was to download the file somehow and actually inspect it in wireshark and with various tools for binary manipulation to see what exactly is triggering the alert. Once I downloaded the file (via tunneling from NAT-ed virtual machine), I loaded it in the Wireshark, and this is what it looks like. At first glance, it was nothing much -...
