Pacifier APT is a cyber-espionage threat cluster active from 2014 through at least May 2016. Also known as Pacifier and Pacifier_APT, it primarily targeted Romanian institutions and was also observed affecting victims in Iran, India, the Philippines, Russia, Lithuania, Thailand, Vietnam, and Hungary. Its operators used spear-phishing emails carrying malicious Microsoft Word documents requiring macro execution, and later ZIP archives containing double-extension JavaScript droppers. Lures included résumés, invitations, conference materials, official instructions, and urgent notices. Pacifier deployed staged Windows malware, including an executable backdoor branch and a malicious Firefox extension masquerading as a language pack. It established persistence through user-level autoruns, modified shortcuts, and scheduled tasks. The malware injected backdoor components into legitimate browser, email-client, and Windows processes, enabling stealthy execution and reducing the visibility of malicious processes. Command-and-control traffic used encrypted or encoded HTTP and HTTPS communications. Supported operations included command execution, file upload and download, file deletion, directory enumeration, configurable beacon timing, and self-removal.
