Just a quick word of caution on sending samples and now pcap files to sites like virus total. While it is handy to have the searchable analysis, remember that anyone can search those results. If you happen to be part of a targeted attack you could be tipping your hand to the attacker. They can be searching sites like this for IP’s and hashes involved in their attack. Once the attacker knows that they have been discovered they could do anything including damaging systems in an effort to cover up.
