Zyxel security advisory for the remote code execution vulnerability of NAS products

Thanks for nothing. NSA325v2 Still working and your team don't do nothing for the users.
I'm not happy with your support, but don't worry, my new NAS will be from other brand.

I see there has new firmware released.

Did you also get a mail from HQ-MKT@zyxel.com via cp20.com?
Doesn´t look professional and I´m scared that I opened a phishing mail or something similar. 

/Edit:
How do you even see that your NAS is hacked? I am so unsure about this code injection because I opened the bloody mail and downloaded the .zip, looked into the .pdf. Only thing I did not do was to manually install the bin file into my NAS as after several bad attempts it updated itself via the autoupdate function. But was it so or did the hack took some tries and then it only looks like updatet?
