This was written on the wall, that it'll eventually reach us...other servers had it for quite some time already.
I'm very disappointed that it's almost here. I have avoided playing games with EAC in the past, because it's one of the worst AC on the market, not in a sense of "game security", but in a sense of user's privacy, not even to mention that it opens a hole in your system that can be potentially used by malicious programs. I do recommend to not take my word on it and simply search online for articles about this AC and what it does.
The best idea would be to play Black Desert from now on a separate gaming-dedicated PC, which obviously is not possible for most of the playerbase. As for the others - do not use your banking, do not enter any passwords anywhere, do not view any sensitive data, while EAC is running, also encrypt all of the sensitive data on your system meanwhile it's not here. If you have a powerful PC - using a Virtual Machine might not be a bad idea.
Most likely, instead of abandoning Black Desert, I'll be adding various tools to Launcher to combat some of the security holes introduced by EAC. I will never recommend to use them, as it might potentially get you a banana, but for me it's well worth the risk (I have way more important things on my PC than Black Desert, including stuff under NDA, albeit it's already extremely encrypted ). And don't worry I don't plan to abandon Black Desert yet, even if I'll get a banana for it (I'll definitely appeal).
Basically you'll need a SHA-2 certificates update installed on your system, which most of you should have it installed on your system already. SHA-2 is not the gimmicky thing required only by Black Desert, so you need it regardless. Launcher also uses SHA-2 certificate for signatures.
