@Sanojei-S all anti-cheat engines are easy to bypass after all the files are in your machine and clearly they learned after all PSO2 is server based and when you do change something from the files a log is generated into the server so they catch those who tamper with GG
All anti-cheats can be broken. Some are far more superior than others, however, and have a better track record of catching cheaters. GameGuard is NOT, and never was, one of those anti-cheats. VAC would be better than GameGuard but then, so would taping up your server and saying "no hack my serverz pl0x" would be better than GameGuard. I digress.
No, they have not clearly learned anything of the sort. You do know that BlueBurst is server-side, not client like EPI&II and V1/V2? Just because a game is server-side does not mean you can't do the same things to it as you can a client side game. The only difference between the two is the encryption between server and client which, hopefully Sega moved on from that atrocious RSA enc (though given their reliance on GameGuard I say old habits die hard) and knowing which string to look for in the buffer during communication between server and client. Once that flag is found, a false flag can be sent back basically saying "hey, everything's cool, it's just me coming in" and off we go to modifying code that can be injected as a string or int value back to the server as a legit command and poof....dupes, hax and powahz! So no, clearly Sega has NOT learned anything from PSO1 because they still rely on the same junky anti-cheat that didn't work then and isn't worth a crumb now.
Yes, I am aware of server nuances. I am a server admin myself as well as a Web Developer and a coder for many years. I wear many hats because I like this field. That said, GameGuard is run by nProtect, not Sega. So, unless nProtect and Sega have some info sharing agreement, which I highly doubt, they wouldn't have a log of who defeated GG. They can, however, log when someone not on the privileged list enters a server which is what I think you meant. But to evade that, you can spoof the IP through a VPN to match an expected IP address from an authorized user (assuming you know that IP already) and there would be no visible evidence of impropriety until things go haywire and they trace it back to the rogue Admin/GM who they finally discover is a hacker. Let's not forget that if you can safely disable Gamemon.des, you can also alter the hosts file to re-route Gameguard to connect to your PC as the server for it's check-files and bypass it that way as most do with Anti-cheats that aren't very effective. Phone-home ACs are trash and everyone knows it. Perhaps this is why everyone hates Denuvo lol. It's an invasive piece of Arks trash (pun intended) but it was hard to defeat for awhile there. But then again, it is essentially a rootkit which is troubling to me.
