Polyfill Supply Chain Attack Rattles WordPress Security
- You’ve likely heard how Polyfill.js, a popular JavaScript library, was hijacked by bad actors in a recent supply chain attack.
- After the polyfill.io domain was acquired by a company based in China, malicious code was injected into the Polyfill library which could lead to vulnerabilities and data theft.
- Polyfills are essentially workarounds that allow modern javascript to run in older browsers. The library is often used by developers as an easy way to offer backward compatibility.
- Analysis of the WordPress repository revealed plugins and themes that were embedding Polyfill scripts from affected domains.
- The current impact is minimal as most affected domains have been taken down, but risk remains if the domains become active again.
- Many agencies received emails from Google indicating that the Polyfill issue impacted their implementation of the Google Maps API (likely from plugins that integrate Polyfill).
- Cloudflare made adjustments to mitigate the issue soon after it was discovered.
- If you need more drama in your life, you can read the back and forth between Polyfill and Cloudflare here and here.
- Patchstack has been an excellent resource for the WordPress community throughout this threat, and they encourage developers to join their mVDP program.
- Patchstack has the details of the attack, including a list of affected plugins.
Cloudflare Fights Back: New Tool Targets Evasive AI Scrapers
- Cloudflare has launched a free tool to prevent AI bots from scraping websites for training data, particularly those that ignore standard bot exclusion rules (like robots.txt) to gain competitive advantages.
- The tool aims to address growing concerns about AI companies scraping website content without permission or compensation.
- Cloudflare analyzed AI bot traffic to fine-tune automatic bot detection models that consider factors like bots mimicking human browsing behavior to avoid restrictions.
- About 26% of top websites have blocked OpenAI’s bot, and over 600 news publishers have blocked it.
- Before you implement a blocker like Cloudflare’s, it’s important to realize that doing so could risk losing referral traffic from AI tools like Google’s AI Overviews.
- The Cloudflare Blog explains the details, and this Techcrunch article can help you decide if this new tool is right for you and your clients.
Mastering the Changing SEO Landscape
- Google’s recent algorithm changes are forcing businesses to reevaluate SEO strategies (again).
- Organic SEO requires a new playbook that measures ROI differently, focussing on building authority and trustworthiness rather than just direct traffic and rankings.
- Content marketing should be focused on creating valuable information for end users that aligns with their search intent, not content that is simply focused on the algorithm.
- Authentic articles that showcase expertise and offer original insights will stand out in the age of AI-generated content.
- Smaller players with real-world experience can outperform larger companies by creating relevant, helpful content.
- TLDR; Focus on users and readers, not the algorithm.
