Case Description:

ANS Networking received a request for service from a local NH Police Department. The contact described strange email and network issues. It was determined that an on-site visit was necessary to troubleshoot the issue.

ANS responded to the inquiry with an on-site visit to examine the current issues and discuss Cybersecurity. After interviewing the on-site contact and examining the network, it was clear that a cybersecurity breach was in process.

Case Study - How Data Breach was resolved at a local police station
Malicious Virus and Malware


ANS Networking determined that virus software was not installed on all computers. The virus software in use was not enterprise type virus software. The router/firewall had no security services enabled and various ports were open for unknown reasons.

Server logs did not indicate abnormal login activity. Remote access from the hacker was not apparent at the time. Some email accounts were not under the end user’s control. Emails were being sent to other departments within the town to propagate the virus payload. Private Facebook accounts were also compromised.


Steps taken to determine the extent of the breach:

  • ANS Networking removed access to the internet on all devices.
  • Server and workstation logs were examined.
  • Router/Firewall logs were examined, and logging was increased to gather more intel.
  • We utilized packet scanning software to inspect traffic from all endpoints and servers.
  • Virus software was introduced to the network to isolate any malicious malware.
  • Reconfigured router/firewall until replacement could be installed.
  • Setup suspected devices on subnet to access the internet for further scrutiny.
  • ANS Networking worked with the FBI to send hard drives to forensics for further examination.


The hacker used a Phishing email with an attached executable. An internal user clicked on the link and installed a keylogger with SMTP. The program copied all keystrokes and sent them to a predetermined email address.

Once the hacker gained access to the external email account, they utilized the account to send compromised email to other users within the Police Department. Other users were subsequently infected and the keylogger was noted on ten percent of the computers.

A.N.S. Networking, Inc., has been the IT service provider to the last two work places I have been in over a span of 20 years. Our experience has been outstanding with service and support when it is needed. We have found they are usually ahead of the curve in terms of current issues and trends. They have always delivered as promised, and are always available when needed. And perhaps most importantly, they will talk to you in common language so you can understand a technical issue and what options there may be for addressing them. As a municipal government, we have also found they are sensitive to our annual budgeting requirements and restrictions. We would highly recommend them for your consideration.

ANS has been wonderful to work with. Brian and Evan have always responded to our calls in a timely manner. They are very knowledgeable and are always very professional. In the last couple of years we have opened two new locations and they did a walk through, ordered what we needed, set up everything and then tested the computers, scanners, server and printers. Brian goes above and beyond. Even on the weekends, when the doctors needed some assistance, we called and in a matter of minutes we were set. I would highly recommend their services. ANS is the best!

A.N.S Networking has been providing our IT services for roughly 15 years. Their expert guidance has helped us to implement new point of sale software, two accounting systems and networks at new locations. They have learned our corporate culture and are sensitive to whether a project is cost or time sensitive. They are always available via phone, email or text message - which is critical for an IT provider. Often they make me aware of potential issues so that we can fix them before they become a large problem. It is so nice to have a company I trust to handle not only the big projects but also small day to day tasks. I would recommend them to anyone. You will not be disappointed.
