The report describes WordPress malware found across roughly 1,980 infected sites since July 2025. The malware uses compromised WordPress plugin/theme PHP files to fetch Steam Community profile comments, extract the commentthread_comment_text content, decode an invisible-Unicode payload with optional AES-256-CTR/PBKDF2/HMAC protection, and inject the decoded URL as frontend JavaScript through wp_enqueue_script using the handle asahi-jquery-min-bundle. The observed decoded payload URL is hxxps://hello-mywordl[.]info/js/lodash[.]core[.]min[.]js. In parallel, the same PHP malware exposes a cookie-authenticated server-side backdoor that responds to DEpjndDbNc ping cookies and accepts base64-encoded PHP replacement code through tEcaKKXEsb plus POST parameter new_code, allowing remote modification of plugin and theme files. The initial WordPress compromise vector is not confirmed by GoDaddy, so this chain starts at the confirmed infected PHP/plugin/theme layer and records initial access as a limitation rather than inventing a vulnerable plugin, stolen credential, or supply-chain path.", "actor_id": "unknown", "observed_at": "2026-05-28T00:00:00Z", "confidence": "confirmed", "needs_review": false, "import_source": "manual-osint-report-to-iim-conversion", "x_source": { "title": "Malware Targeting WordPress Abuses Steam Community Profiles for Command & Control Operations", "publisher": "GoDaddy Security / GoDaddy Resources News", "author": "Krasimir Konov", "url": "https://www.godaddy.com/resources/news/malware-targeting-wordpress-abuses-steam-community-profiles", "published_at": "2026-05-28", "accessed_at": "2026-05-30T00:00:00Z", "source_type": "original vendor research report", "source_policy": "Original GoDaddy Security source only.
