How I built a lightweight standalone behavioral anti-stealer to protect my Windows environment

Short summary

A developer built an open-source, Python-based behavioral anti-stealer for Windows that monitors active sockets every 5 seconds and terminates processes exhibiting hollowing or injection patterns from temp directories. The tool targets modern infostealers like Lumma and RedLine without signature databases or cloud telemetry. The author seeks community feedback on whether a 5-second polling interval is fast enough to catch DPAPI decrypt-and-dump cycles.

• •Open-source Python anti-stealer (~9MB) monitors sockets every 5s for infostealer exfiltration
• •Uses process lineage validation to detect hollowing/injection from temp directories
• •Author asks if 5s interval is sufficient against fast DPAPI dump cycles
