Continued widespread dictionary / brute force attacks

CTC NEWS, Industry News
Over the past two weeks, we have seen a significant spike in the number of brute force attacks against SSL VPN endpoints and VPN web portals. Initially, the traffic was coming from several hundred IP Addresses but we were pretty quickly able to distill it down to about 47 netblocks from two geographic areas (Russian Federation and China). All of the login attempts were failing and in the initial set of login attempts the usernames were varied and included admin, administrator, vpnuser, sslvpn, backup, user, sales and others. This most recent set of attempts though were for admin and administrator and, after distilling the data down we saw a new pattern emerge. A very small number of the attempts are now coming from domestic IP Addresses and, specifically, some of…

Possible delays in support due to labor shortage

CTC NEWS
Like many small businesses, we are feeling the strain of the labor shortage. In most cases, we have been able to schedule around it but we are seeing our response times start to stretch out longer than we would prefer. As a result, we are having to triage and prioritize some support requests and want to be very transparent about how this prioritization works. We will prioritize first based on customer type (MyIT, Commercial and Residential) and then based on the request types detailed in our Policies and Procedures page here. In any case, we will continue to respond to all support requests same day and, in most cases, within four business hours of receiving the request. We will continue responding to and addressing support requests as promptly as we…

Widespread brute force / dictionary attacks overnight

Industry News, Tech news
We received notifications from literally every Internet facing firewall that we have deployed as well as a number of honeypot devices for failed login attempts from an IP Address 45.134.144.200. This IP Address is in the same network (45.134.144.0/24) that we've seen similar traffic from in the past and we have no indication of any legitimate traffic to or from that network in the past 12 months. If you manage one or more networks with Internet connectivity, it may be worth looking into this network range to see if there has been any traffic (or successful logins). For our MyIT clients, we had already blocked a few specific IP Addresses based on similar traffic in the past but are now updating all of our managed firewalls to block the entire…

Delay processing support requests via email

CTC NEWS
We are currently experiencing an issue processing (receiving) support requests received via email. This includes any new requests as well as email replies to existing requests. We are working on the issue now and expect to have it resolved quickly but wanted to let everyone know. If you need immediate assistance, please call the office at 770.386.8900. Update @ 1017 - The issue appears to be that the legacy authentication (POP3 over TLS) has been phased out a little earlier than originally expected and our helpdesk / ticketing system was temporarily unable to process incoming support requests. Ultimately, we were able to move up our plan to upgrade and are now good to go.

Windows 11 is Here - Microsoft is wasting no time getting it's new flagship desktop operating system Windows 11 rolled out to (often) unsuspecting Windows 10 users.
