New commercially available mass FTP-based proxy-supporting doorway/malicious script uploading application spotted in the wild

This practice led to the emergence of DIY (do-it-yourself) tools and managed service platforms that allow virtually anyone to start monetizing these fraudulently or automatically registered accounting data, signaling a trend towards an efficiency-driven cybercrime ecosystem – a concept that’s been materializing on a daily basis for a couple of years.

I’d say it’s ironic that […]
