    Hi, I am facing the same issue since 26th July. I contacted Sophos support and got a pathetic reply. All we need is an explanation why this is happening or an acknowledgement that Sophos is looking in to this.

    Below is the reply I got to my inquiry from Sophos. I have removed my internal IP address and the name of the technical agent.

     

    Hello Shenath,

    This is regarding the service request number 9037848.

    According to the logs, the attack is been detected and the source IP is ***.***.***.***.
