SECURIY ISSUE: VC400 being brute forced and dont stop calling - HenriqueMachado - 01-04-2019 11:53 AM Hello! Henrique from Brazil Today my VC400 started receiving calls one after the other. When I look who is calling it show like SQL Injection codes: admin' -- admin' # admin'/* ' or 1=1-- ' or 1=1# ' or 1=1/* 1' or '1' = '1 ') or '1'='1-- ') or ('1'='1-- What can I do? Is there a way to protect my VC400 from these scanners? Like a password before calling or something like that?

Henrique from Brazil Hi Henrique, May I suggest to do next steps? - Disconnect the VC400 from your LAN. - Check your router firewall configuration if the right ports are set. - Reset VC400 Codec to factory default. Using tiny objects (for example, the paper clip) to press and hold the reset button for 15 seconds until the screen turns black. - Change User password into a strong password (>16 char) or disable the user mode - Change Admin password into a strong password (>16 char) - Connect the VC400 to your LAN - (Re)configure the device and check again. Hope this will help. |
