Gx works2/Gx iec developer

Post by SolidRio » Fri Oct 27, 2017 4:42 am

Hello everyone. So... i got question that i cant answer by myself after a long period of time, so i came here for a help or advice.
I got 3 project on my plant for FX3U (all 3 of them).
1 project was made in GX IEC Developer, there arent problems with uploading him from plc. And there are passwords on the almost all blocks and the libraries.
Like this:

And to unlock you must write the password in this menu:

All i can do is download this project in PLC and upload with gx works2 or just developer in just simple LD with tons of code without any comments.

And there is no information about lenght or type of password in the manuals (like how many symbols/ which special symbols like `';></difference between A-a/etc).

2 project was made in GX Works2 and he is easily uploading from the PLC. In the project used user authentication:

We know login and password for the user that cant open FBs and do changes:

But we know from the menu admin login and there is information about what password can be:

We still can use method of reading code like i described in first project.

And 3 project was made in GX Works2 without user authentication, but there passwords on all blocks:

And we know what password can be:
https://image.prntscr.com/image/vkEoxoU ... N_VmQA.png
In this case of security - you cant upload program from plc even in simple LD, you got message that in the project no symbol information (which you cant upload in FX3U) and some of blocks got password, so... you even can write a password cause there no window for that, just a message.

I hope i described all in details, but if there are any questions - i will answer them. I got some ideas like bruteforce unlocking (put all possible combinations of password) but i cant find any programs for this. Or idk maybe there somewhere in the project hash file with the coded passwords (but in case of gx works2 there only 1 file contain all project). I dont know. I really need help. I googled this questions to death and even find some topics on this forum with the man that offered a help, i pm-ed him, but still no answer =( So... Thanks even if just read this message. :)

Hello again. So... I tried to find help from Chinese region.
I found 3 links. First 2 on 2 case of my first message. Last about the 3 case of protection.

But i am looking on those sites through google translate. Maybe there is Chinese speaker? I will be grateful for any help.

And if there are sourses on unlocking and user authentication and blocks passwords, so it can be unlocked.
Снова здравствуйте. Итак, я попробовал найти помощи у китайского региона.
Нашел 3 ссылки. Первые 2 по второму случаю моего изначально сообщения. Последняя о 3 случае защиты.

Но приходится смотреть данные сайты через гугл переводчик. Быть может здесь есть говорящий на китайском? Я буду благодарен за любую помощь.
И если есть источники продающие разблокировку и авторизации пользователей и пароли на блоках, то это значит, что это может быть разблокировано.
