Wrap-up: What? No Link?
Our handler John Bambenek, in hisdiary from December 7th, noted the dangers of posting URLs, in particular clickable URLs, on our site. To drive the point home, he added a "suspect" URL, and we tracked how many people clicked on it.We had about 1,000 users click on the link. 80% used the same browser they used to read the diary, so I consider them "production browsers". 10% used "safe browsers" like wget. The remainders are bots/search engines that followed the link.Most people who responded to the diary noted that they do need access to malicious code (and malicious URLs) in order to be able to block them at their web proxies, or that they use safe browsers to access suspicious links. We will continue to post links in our diaries. It is up to the particular handler to decide if it is appropriate to obfuscate the URL, post a partial URL, or not post it at all if it is deemed not appropriate or too risky. I will be teaching next: Intrusion Detection In-Depth - SANS Boston Summer 2019
