HI there,
I was recently referred to a new client, during my initial inspection I noticed the Mikrotik (951Ui) was running FW 6.43.2 (Sep 2018). This is an ISP provided unit that seemed to escape the ISP's 6-month checks for quite some time..
They (ISP) have since updated the router (remotely) to one of the 2021 FW's, but this does not sit well with me,. I air on the side of caution & have mentioned to them (ISP) that they should consider the router as compromised & replace it outright. They (ISP) seem to believe the router has never been compromised, something I struggle to believe due to the fact that the router was left unpatched for so long, despite being "managed".
I would love to hear from Mikrotik & the members on this forum.
Thank you!
