Phishing is to blame for this latest infiltration.

According to leaked internal documents, Activision had a bit of a security breach on December 4, 2022. It was on this date where someone with high-level access to the internal Activision network was phished and their credentials used to access information that should have never been made public.

It's not really clear yet how much of the information that was leaked only today is accurate. There is also no saying whether any customer information was obtained during this security breach. Activision has made no public comment about this security intrusion.

What we can see in some of the files that made their way online today are Activision's plans through to November 17, 2023. These plans mostly focus on new seasonal content for Call of Duty including both Modern Warfare 2 and Warzone 2.0. Also included in the documents are references to something called "Project Jupiter."

Taking a look only at the images posted in the tweet above, we can see a few things. We can see that as of December 4, 2022, Season 3 for Modern Warfare 2 was set to run from March 15 through May 15. This season would add two new Operators, three weapons, three 6v6 maps, one Ground War-sized map, and more.

Season 4 would then run from May through July and add two more Operators, three new weapons, two 6v6 Core maps, two Ground War-sized maps, and more. Season 6 would run from September 15 through November 8 and offer two more Operators, three weapons, two Core maps, and one Ground War map. Information about Season 5 was not included in the images above.

When it comes to Project Jupiter, it reportedly had an entry on the schedule for an alpha test around the late May to early June window. Beyond that, there is no information as to what this may actually be.

Again, this should all be taken with a grain of salt. Dates and the amount of content are subject to change. Without any sort of confirmation about this security breach, it's difficult to say whether or not this is even real in the first place. As an addendum, it seems as though not everyone at Activision was fooled by the phishing attempt.
