The malware only fired when a logged-in WordPress administrator loaded an affected page. It hijacked the admin’s own authenticated session to create hidden administrator accounts and install a self-hiding backdoor plugin that gave the attacker full control of the site.

Pre-staged lookalike infrastructure is a planning signal worth watching for. - Tags: security, atom/literature/h2, threat-intel - Where those earlier attacks compromised WordPress.org’s distribution pipeline, this one hit upstream for Awesome Motive. Sansec’s Forensics Team compared it to the Polyfill supply chain attack it discovered in 2024: “Tamper with a single upstream file, and the malware reaches thousands of downstream sites without ever touching them individually.” ([View Highlight](https://read.readwise.io/read/01kv8ac2w34fpzdba59fwnarha)) - Note: CDN-key theft is a supply-chain multiplier: "tamper with a single upstream file, and the malware reaches thousands of downstream sites without ever touching them individually" (Sansec, comparing to the 2024 Polyfill attack). One upstream compromise → 1.2M sites. - Tags: atom/literature/h1, security, supply-chain
