Fake WordPress distribution site
When I logged into my WordPress dashboard on my other website, I noticed this interesting article over at weblogtoolscollection about a website that has a fake version of WordPress for download. Apparently, they are calling this version of WordPress v2.6.4 which, as any WordPress user should immediately recognize, does not officially exist [at least not yet]. The software that you install from this site is actually a trojaned version of WordPress that seems to be based on some old vulnerabilities.
So the next time you go to upgrade or install WordPress, ensure that you are getting the files from http://wordpress.org and not a scam website.
