  "technical_summary": "RisePro is a native C++ information stealer architecturally related to the Vidar malware family. Widely disseminated through Pay-Per-Install (PPI) distribution syndicates such as PrivateLoader, RisePro communicates with its C2 infrastructure over direct raw TCP sockets (typically ports 50500 or 50501) using custom binary packet framing rather than standard HTTP. Its execution logic decrypts an embedded configuration structure, performs environmental checks, connects to the C2 to retrieve dynamic file-grabbing regex rules, extracts credentials from browsers, VPN clients, cryptocurrency wallets, and 2FA extensions, and streams the exfiltrated archive directly over the raw TCP socket."
