line inserted in .htaccess by joomla update? or...?

[reggaebkk]

Hi,

I am having problems with dns resolution on several Joomla websites and I am not sure if the websites were hacked or from the ISP's DNS servers, still inquiring (here is Cambodia, ISPs are not 100%).

But many of my websites have had this line inserted in .htaccess:
# requested URL ends with one of the listed extensions
RewriteCond %{REQUEST_URI} /component/|(/[^.]*|\.(php|html?|feed|pdf|vcf|raw))$ [NC]

Host support says that it's a normal server command but I don't see it in Joomla's htaccess.txt...
Can that have been added while doing Joomla updates?

Or does that smell like my websites have been hacked? I have started inspecting folders but so far all seems normal.

If it's part of a hack, can somebody tell me what kind of hack I should be looking for?

Thanks if you have time to help.

RewriteCond is like having a conditional structure where the condition's occurrence causes the rule to be triggered. So question here- what is the follow up RewriteRule, if any.

From the general problem description, it looks like more of a problem related to relative path configuration rather than security issue.
