WordPress Ops: Google's 'Preferred Sources' & The Malware Spike

Google just handed independent publishers a way to fight back against AI scraping with their "Preferred Sources" tool, while hackers are simultaneously punishing anyone who ignores their composer.lock with a massive new malware campaign.

Why I'm Watching This​

If you run a WordPress site in 2026, you're fighting a two-front war: visibility and integrity.

  1. Visibility: AI Overviews often bury the original source. If you break a story or write the definitive guide, you want Google to know you are the primary source, not the AI summarizer.
  2. Integrity: The "Widespread WordPress Malware Campaign" reported this week isn't sophisticated—it's just opportunistic. It targets the lazy.

I've been spending time this weekend auditing my sites against these two updates.

The Analysis​

Google's "Preferred Sources"​

According to the latest reports, this tool allows publishers to explicitly signal "original reporting" via structured data or Search Console configuration. It's effectively a canonical tag for facts.

Here is how the flow changes for content producers:

If you are a technical writer or news breaker, ignoring this means you are voluntarily feeding the model without getting the traffic credit.

The Malware Wave​

The report from Squared Tech highlights that this campaign specifically targets "outdated plugins." This isn't a zero-day exploit in core; it's an exploit of the "set it and forget it" mentality.

The most dangerous thing you can do right now is rely on auto-updates that might fail silently. You need active scanning.

# Don't just update; audit first.
# Check for known vulnerabilities in your lock file.
composer audit

# If clean, then update safely
composer update --with-dependencies

The Code​

No separate repo—this is an operational update based on industry reports.

I am currently updating my drupal-eu-sovereignty-checklist (which applies to WP as well) to include a check for these "Preferred Source" meta tags, as I suspect this will become a compliance standard for EU publishers wanting to protect their IP rights.

What I Learned​

  • SEO is now "Source Authority": Keywords matter less than proving provenance. If Google offers a tool to claim authorship, use it immediately.
  • "Preferred Sources" needs Schema: While the UI exists, likely the heavy lifting is done via JSON-LD. I'm digging into the specs to see if NewsArticle schema needs a specific property for this.
  • Composer Audit is non-negotiable: The malware campaign targeting "outdated plugins" is easily thwarted by running composer audit in your CI/CD pipeline. If you aren't blocking deployments on high-severity CVEs, you're asking for trouble.
  • Old plugins are liabilities: If a plugin hasn't been updated in 6 months, replace it. The attack surface is too high.
