Seems that the recent Hen release for the PS4 has kicked up some dust, heres the news from eurasia:

After Flatz revealed a lot of details on how to create our own package files (arguably, for the sake of streamlining future homebrew support), it was only a matter of time: piracy is now a thing on PS4 4.05. And it appears to be much more easier than it used to on firmware 1.76. There’s already been multiple "dumps" of 4.05 compatible games circulating on the intertubes, and several scene members have confirmed these packages do work. People who worry about piracy for the sake of game preservation have warned that the current dumps being circulated will lead to compatibility issues in the future. But people willing to play AAA titles for free on their 4.05 will most likely not care about those details.
