I am curious to know if the organization I work at gets a blast email to 500 employee's from an external B2B marketer does the wildfire analysis get performed on all 500 identical emails or does it simply do it once knowing the email and links are identical.
Actually yes, the firewall is doing the analysis for every email. It does not really care about the url, it simply forwards it to wildfire - in batches of 200 URLs per upload or all 2 minutes - depending on which limit is hit first. About the list of trusted sites I am not sure, as theoretically there is nothing like trusted site. On every website there is the potential risk that it gets hacked and will be used to host malware or exploit kits. But at least I think, there is a timer that a website is not ddos'ed by wildfire and only scanned for example max. once per hour or day. About a local check if the urls are identical, @jdelio could you say something about this? But often the links in such mass-emails aren't identical, every link is different to track which recepient clicks on the url.
@vsys_remo and others..
From the official documentation on WildFire email analysis..
"WildFire visits submitted links to determine if the corresponding web page hosts any exploits or displays phishing activity. A link that WildFire finds to be malicious or phishing is:
@jdelio My question was more about if the firewall already does a local check for the urls? Or does it - in the case like in this topic - upload 500 times exactly the same URL to wildfire if there are 500 incoming emails with this one URL?
Actually I was able to get the details from people who looked at the code, and other detailed info.. and it looks like there will be 500, because each one comes from a different email header and we produce separate reports with the specific session information associated with the SMTP, IMAP or POP3 session. So, all links are sent to the cloud at this time, duplicate or not.
