VERY IMPORTANT

DePriMon is a malicious downloader, with several stages and using many non-traditional techniques. To achieve persistence, the malware registers a new local port monitor – a trick falling under the “Port Monitors” technique in the MITRE ATT&CK knowledgebase. For that, the malware uses the “Windows Default Print Monitor” name, that’s why we have named it DePriMon. Due to its complexity and modular architecture, we consider it to be a framework.
