Exclusive: Ongoing malware attack targeting Apache hijacks 20,000 sites

Tens of thousands of websites, some operated by The Los Angeles Times, Seagate, and other reputable companies, have recently come under the spell of "Darkleech," a mysterious exploitation toolkit that exposes visitors to potent malware attacks.

The ongoing attacks, estimated to have infected 20,000 websites in the past few weeks alone, are significant because of their success in targeting Apache, by far the Internet's most popular Web server software. Once it takes hold, Darkleech injects invisible code into webpages, which in turn surreptitiously opens a connection that exposes visitors to malicious third-party websites, researchers said. Although the attacks have been active since at least August, no one has been able to positively identify the weakness attackers are using to commandeer the Apache-based machines. Vulnerabilities in Plesk, Cpanel, or other software used to administer websites is one possibility, but researchers aren't ruling out the possibility of password cracking, social engineering, or attacks that exploit unknown bugs in frequently used applications and OSes.

has to be the most poignant I've read in a long time.

Quoting:Every time another of these articles comes out, it makes me freak out and try to look at my home server and see if there is anything wrong with. Every time I quickly realize that I simply don't have the expertise to determine whether there is anything wrong with my server, and am doomed to never know whether my own server is being used to put viruses on my own machines or not :(




That's like always saying you're a mechanic and having your own custom built car...then when it breaks down, not knowing how to fix it.

If that's the case, why did you call yourself a mechanic all those years?

People should perform due diligence and learn about the systems they operate...learn enough about them that you can at least operate, support, and troubleshoot issues on them. Otherwise, it is negligence at it's highest example.

I suspect that this attack goes after a known vulnerability in Apache servers configured with ssh operating over port 80 & that allow root logins. This is probably similar to the vulnerability that effected Asterisk servers that had their administration exposed to the web... My guess is that it's yet another example of hacks setting up web servers without knowing what they're doing.
