What Funnel Builder WordPress plugin bug exploited to steal credi Means for Quezon City Businesses

A Quezon City e-commerce shop owner checked their WooCommerce sales last week — and had no idea their checkout page was quietly harvesting customer card numbers.
If your WordPress site uses the Funnel Builder plugin, this is not a hypothetical. Attackers are actively exploiting it right now.
What the Attack Actually Does to Your Checkout
Malicious JavaScript gets injected directly into your payment page. Your customers see nothing unusual — but every card detail they type is being copied and sent elsewhere.
Your team probably won't catch this through normal monitoring. The script is invisible to shoppers and blends into your existing page code.
When this hits a Quezon City retail or food delivery operation, the damage is doubled — you lose customer trust and face potential liability under the Data Privacy Act.
Key Insight
Skimmer scripts injected through plugin vulnerabilities typically survive cache clears and basic malware scans because they live inside legitimate plugin files, not obvious locations.
What to Do Before Your Next Sale Goes Through
You don't need to take your site offline — but you do need to act today, not after your next brownout-delayed Monday morning.
- Update Funnel Builder to the latest patched version immediately
- Check your WordPress plugin list for anything unrecognized or outdated
- Scan your checkout page source for unfamiliar external JavaScript calls
- Enable two-factor authentication on your WordPress admin account
- Ask your hosting provider if they have a Web Application Firewall active
Pro Tip
Pro tip: Quezon City SMBs on shared hosting plans — common with local providers along Commonwealth Avenue — rarely have WAF enabled by default; call and ask specifically.
Stop the Bleed Before a Customer Dispute Does It for You
One compromised transaction can trigger a chargeback investigation that freezes your payment gateway for weeks.
That is a harder recovery than the patch itself.
Quick Win
Quick win: Log into WordPress now and check Funnel Builder's installed version against the official changelog.
