Using Chrome, I went to a website of a company we were researching, following a link from a google search, and got redirected to a malicious website. After killing Chrome and scanning for viruses, I decided to investigate. In a VM, I did the same google search and took the same link, but this time there was no redirect. I think tried not in a VM and same thing, no redirect.
The site is Wordpress-based which makes me thing that they may have been compromised, as I've heard this is common for wordpress sites.
At this point though, it could have been another page or ad on another page opening a malicious window. I checked my history but I have no way to tell how the window got opened. Clicking on their site could have been just coincidence. I've been trying to see if there is a way to detect what opened the link, but have not found one yet. What I'd like to know is if I can confirm that this is happening on their website so I can report it to them. For instance, if it's possible for me to detect something like this, assuming it's not happening regularly or to me anymore.
Edit: I forgot to mention that the website has very little "live" data on the page, as it's mostly informative. There are no ad banners or anything like that, though they do have a twitter feed at the bottom. This seemed to rule out a malicious advertising network.
