Having been involved in OTT for many a year it was always obvious to anyone working in the industry that the whole DRM system is mostly a waste of time and money. This is the system that the movie industry forces on the OTT industry through lobbying that has driven up the cost of everything.
The idea being that if you pay for DRM that at least if anything happens, meaning someone steals a stream, you can say you are covered by so and so’s DRM. Essentially DRM is like insurance.
However, if you have ever worked in the OTT industry, the general security around how movies are sent around would floor you. Companies mail hard drives around, ship DVD’s, put movies on Google drive and all sorts of file transfer methods that are semi secure or not even remotely secure.
But since all these systems are run by people, usually any sort of leakage starts from the inside and involves people paying for access. Or, there is just a lack of security and any system that is based on people will usually have a flaw or someone makes a simple mistake which will allow a sophisticated tech person a chance to steal stuff.

In this specific case it sounds like the hacker got into the post production studio’s system and was able to take the episodes. These episodes probably were not even completed or ready to be streamed. Around the emerging markets there is quite a racket for copying the movies and selling them to pirates while they are being transferred around, supposedly in safe hands, but in places like India it is quite common for the film canisters to be dropped off at the pirates on the way to the cinemas.
I am sure Netflix is pissed and will be interesting to see if they figure this one out. As more and more media moves to online only – my guess is this type of situation will happen again. It also brings to light the issue in companies like Netflix realising all episodes at once since in order to do this all the shows have to be ready to go. This means all the shows are sitting there if someone gains acccess where in a normal TV show- they are being made as you watch or getting finished as you watch.
