Explore our curated collection of malware logs, providing insights into various threats affecting WordPress sites and how to mitigate them.
Malicious PHP code discovered in WordPress theme’s functions.php file containing a sophisticated backdoor that creates a hidden administrative user account with advanced stealth capabilities.
The WordPress website has been compromised with obfuscated JavaScript malware that hijacks user click events and redirects mobile device users to malicious URLs. The malware exhibits sophisticated evasion techniques including mobile device detection, time-based delays, and localStorage persistence tracking.
During routine monitoring, we detected anomalous behavior on a WordPress site, including unexpected redirects to fake security verification pages, unauthorized file upload forms in the interface, and server resource spikes. Logs revealed persistent unauthorized access attempts, with modified files in key directories like wp-content/plugins. The infection caused temporary site instability, but no confirmed data loss was observed. This triggered a forensic investigation to identify the root cause and mitigate risks.
WordPress sites are displaying fake Cloudflare CAPTCHA prompts (e.g., “Human Verification Required” or “Unusual Traffic Detected”) that do not originate from Cloudflare. Upon interaction (e.g., clicking “Verify“), users are redirected to phishing sites, scam pages, or domains hosting malware. This often results in browser hijacking, data theft, or secondary infections. The malware persists in site files, surviving updates if not fully removed, and can spread via fake plugins or themes embedded in legitimate ones.
The client reported unauthorized redirects from their website to a malicious URL: https://analyticacnodec.com/d3af16CD2ebF1718/. This occurred selectively on Windows-based browsers, with network requests to analytwave.com observed in developer tools. The issue involved injected JavaScript in two site files, leading to intermittent hijacks. Key concerns: visitor data theft, SEO penalties, and potential server compromises.
