Attack / Virus

Hey everyone,

A user has reported something suspicious, and it's an attack directed at Google Chrome users from what I can tell.

If you see any page asking you to install a missing font, DO NOT DO IT.

If anyone sees this popup / error / page, please let me know as I haven't tracked down how the attacker is doing this.

If it's one post or topic, please let me know which. Perhaps it's just something embedded in a post text.

Thanks,
-Rob

I can't reproduce it with Chrome on Linux. Can someone on Windows try? You may need to come from Google search, so searching for "site:brewnosers.org brewing" might lead you to it.

Maybe it's just some specific topics with some embedded image / javascript somehow. I need to find it to kill it.

I had it on my home PC.

I resolved it but going to settings/advanced settings/reset settings.

it went away

bottom of the page...malware software didn't pick up on anything...maybe because i didn't click install on the virus popup

Definitely there if you link to the site via a Windows Google Search "site:brewnosers.org brewing". First two forum links give you the attached screen:

While on that page, can you view source and see Hoefler anywhere in the text? I can't. But perhaps it's only in the initial load from Google.

Odd. If you can get it to happen again please update.

Wordpress was highly suspect so I removed it. It's still puzzling but it was at the top level of the site. Looking through it's files there was something fishy as well. Wordpress has been a common attack vector for a long time, we don't maintain ours. Therefore I figure it's a liability so I removed it.

If anyone wants to replace the main web page I'm open to suggestions.

If anyone can reproduce this Chrome font thing I would like to know.

Thanks,
-Rob

Update: I was able to reproduce this several times in a row before replying, but while checking what version of Chrome i had, it initiated an update. Now it is on Version 57.0.2987.98 and I am no longer able to reproduce it, and the source no longer has the above snipped i posted.

I used chrome to access the site for the first time today, had been using firefox. Got the virus warning. Tried to view source but the popup no longer appears.

Hi I am using a different computer and visited the site using chrome and got the virus. I saved the source for the whole page if its any use to you. Let me know if you want me to upload the txt file as an attachment or email it?
I got there by typing brewnosers in search and it was the first.
The google link is https://www.google.ca/url?sa=t&rct=j&q= ... OVt7nYTYfw" onclick="window.open(this.href);return false;

I believe its cached so it may be a problem you no longer have. Don't know if you can request google to refetch the page due to this issue

It just happened to me again.

This is the culprit: https://malwaretips.com/blogs/remove-ch ... exe-virus/" onclick="window.open(this.href);return false;

Here's a forum post about server admins talking about trying to get rid of it. They apparently eventually did but they didn't post how they did it:S http://forum.odroid.com/viewtopic.php?t=25568" onclick="window.open(this.href);return false;

After 5 minutes or so it stopped happening again. Probably a strategy to prevent it from being fixed.

Here are a few pictures of it happening
