I think my S100 is hacked. When trying to login to web gui, I get "ERR_INVALID_REDIRECT" message and after a closer look in developer tools I can see that one of responses from pbx web server is:
data:image/png;base64, ...(base64 encoded image code)...
What would be the proper way to solve this issue?
Is it possible to bring back web gui without factory reset?
Thanks in advance!
