Help Desk - Procedure for Handling and Proactive Notification of Security Disabled Accounts

Security will disable UW-Net Wireless and WiscVPN access for accounts that have been compromised due to malware infection, and the Microsoft 365 team will disable email accounts that have been compromised due to a phishing attack. The Help Desk receives notification that the account has been disabled and will attempt to contact the user to alert them of this and provide information for resolving this situation.

 

HDQAs: If you are ever unsure about how to handle a Security case, feel free to message the CSOC Advanced Support Channel in MS Teams or re-escalate the case to the Security-BADGIRT team in WiscIT.


NetID / Microsoft 365 Disabled

HDQA

  1. You should locate the customer's phone number and put it in the case.
  2. If you are able to locate a phone number, assign the incident to callback by a phone agent.
  3. If a phone number is not able to be located, add a journal note stating "No phone number found, setting case to pending: customer contact required", and set the case to Pending: Customer Contact Required.

Q: How did this happen? Can you tell me what I clicked on? I don't think I did this.

A: It is hard to find exactly how credentials could have been compromised. All I can say for sure is your NetID and password were compromised and being used to sign in by someone other than you. Commonly, if you use your NetID username or password on third party websites, your password may get compromised after it is leaked from the third party site. It may also happen if you logged into a website that was pretending to be UW-Madison login but was instead a malicious website posing as UW-Madison, arriving from a phishing email.

UW-Madison's Security team takes these steps for your protection to make sure any malicious actors who may have been logged in to your account are forcibly logged out.

  1. If the customer calls the Help Desk, skip to step 4.
  2. If a callback is assigned to you, call the customer
    • If the customer answers the phone go directly to step 4 when they pick up.
    • If you reach the customer’s voicemail, skip to step 3, and use the script provided.
      • Set to Pending: Waiting For Customer if they answer
      • Set to Pending: Customer Contact Required if you receive their voicemail
    • If someone other than the customer answers or if the customer is not able to complete the steps at this time, provide the case number and Help Desk phone number and ask for them to have the customer call us back. Set the incident to Pending: Customer Contact Required
    • If you reach the wrong number, a disconnected number, or are unable to leave a message for the customer, add a journal note stating "{The reason contact could not be made}, setting case to Pending: Customer Contact Required", and set the case to Pending: Customer contact required.
  3. If you make contact with the customer's voicemail, identify yourself using the following script:
    Hi, this is X from the University of Wisconsin, Division of Information Technology. Your NetID and Microsoft 365 account were disabled due to suspected compromise. For your protection, we have disabled your access to these services. To resolve this issue, please go to http://helpdesk.wisc.edu and search for 52781 and follow the instructions. Once you are done following the instructions, please call the Help Desk at 608-264-4357 and reference the {CASE NUM}.

    Note: If the customer answered the call during a callback and you have completed the script above, complete the steps below. If the customer is weary whether or not we are the DoIT Help Desk, have them call us back or find our number from Google!

  4. When the customer either calls back or calls for the first time:

UW-Net Suspicious Activity Report / Disable

Often times, cases for UW-Net disables will be paired with a VPN disable. This section will just go over how to reenable UW-Net access. Make sure to check WiscIT for an already open case!

    1. The security case will be in the HDQA queue. Look in the case specifics and see if UWNet DISABLED is checked. 
      • NOTE: You can also see the customer’s device’s mac address in the specifics. (The MAC and IP may not match what's notated in the specifics section)
      • The attached csv file is the network log alerts from the previous 24 hours
        CSOCSpecifics
    2. If disabled is checked use the “CSOC -DISABLED- Suspicious Activity Report/Compromised Device” email template. Be sure to put in the customer's mac address, device name, and device description into the template email. (If the CSOC is requiring the computer to be inspected onsite, do not enable the device over the phone)

      If disabled is unchecked use the “CSOC -NOT DISABLED- Suspicious Activity Report” email template. Be sure to put in the customer's mac address, device name, and device description into the template email. 

      If vpn is checked use the “CSOC -VPN- Suspicious Activity Report” email template. Include device name and device description into the template email if available. 

    3. Leave a note on the case for the next agent stating that they should follow 8595 for next steps. Keep the case in the QA queue. 
      Journal Note:

  • When customer calls in, please see KB document: 8595 > UW-Net Suspicious Activity Report / Disable > Phone Agent
  • These are instructions on how to handle this incident
  • Please consult HDQA with any questions

4. Leave the case in the QA queue when prompted after sending the email to the customer 

*HDQAs are always welcome to use the CSOC Channel in the Advanced Support Channel if they have any questions

Q: How did this happen? Can you tell me what I clicked on? I don't think I did this.

A: This happens when our firewall notices repeat (100+) traffic routing to a certain bad website or if your device is receiving messages or communicating with a malicious server to let the server know you're online. Bad browser extensions, toolbars, or adware may cause these issues to pop up.

Cybersecurity cannot detect what caused the traffic routing issues. It's best to run a virus scan and check for bad extensions or toolbars if you receive this type of notification.

When the customer calls in:

  1. Put their name in requestors incidents and find the open case for them. It will be titled “Suspicious Activity Report.”
  2. Check if the device is disabled or non-disabled through the case description 
    CSOCDisabled
    If the “Disabled” box is checked, that means the device is DISABLED in Clearpass 
  3. When the customer has a NON-DISABLED device
  4. When the customer has a DISABLED device:
  5. Set the incident to Resolved and leave a journal note detailing steps taken and the end result
