Malware As A Service
by Artie Kaye

EvilProxy is the name given to a set of software and tools available on the dark web.  It functions as a subscription program, like Adobe.  It functions using reverse proxy protocols and cookie injection.  The main source of infection is via phishing scams.  It can bypass two factor authentication.  The ease of use and functionality can allow a bad actor to cause a lot of harm, even with little knowledge.  Its use has been linked to attacks on the Python Package Index, and the Twilio breach.  It is a relatively new weapon that is still being refined and used against people online.
