WordPress Hacks Behind Surging Neutrino EK Traffic

msm1267 writes: More than 2,000 websites running WordPress have been compromised and are responsible for a surge this week in traffic from the Neutrino Exploit Kit. Attacks against sites running older versions of the content management system, 4.2 and earlier, were spotted by Zscaler. Those sites are backdoored and redirect a victim's browser through iframes to a landing page hosting the exploit kit where a Flash exploit awaits. The exploits generally target Internet Explorer, Zscaler said, and victims' computers are eventually infected with CryptoWall 3.0 ransomware. This analysis is in line with a similar report from the SANS Institute, which pointed the finger at a particular cybercrime group that had steered away from using the prolific Angler Exploit Kit and moved operations to Neutrino.

    WordPress is a security problem

    I know I'm going to catch flak for this.

    WordPress and all of it's plugins and themes are a huge target for hackers and reliably available online.
    The main problem is that users don't regularly update, or rather that they can't in many cases.
    That is, assuming the plugins are updated for security holes at all.

    I wouldn't be surprised if hackers had databases of the exact versions, plugins and themes of millions of WordPress installations.
    Just wait for a new public disclosure, replicate the exploit and attack the matching sites in your database.
    They could have hundreds of freshly hacked WP sites every week.
    These sites may only stay hacked for a few days or weeks, but it's simple economics.

      Yes, WP is a security problem, but the problem isn't the end users, or even the site owners. It's the general low quality of development skill that the WP ecosystem thrives on. The WP codebase is laughable crap, but makes it easy for entry-level, self-described developers to get something done, although without understanding the ramifications of the sloppy way they did it. They learn such sloppiness from the WP core itself, plugins, or the plethora of half-assed tutorials written by people who have only a fraction more clue about code and security than they do. WP culture is a feeding frenzy of ineptitude. The core was lousy when it was first released, and the dev team's adamant refusal to break backwards compatibility keeps a surprising portion of the internet at risk.

      PHP4 is long gone, but WP core still has over 2000 instances of the global keyword. Only a language as poorly designed as PHP (but which has made tremendous improvements in recent years) could allow garbage like WP to thrive.
