Malware Detection at OSU
Oregon State University utilizes a device on our network called FireEye. This device monitors the network for patterns of activity a computer displays when it is infected with malware, or has been compromised by hackers.
When the FireEye device detects signs of malicious activity, it sends an alert to the OSU Computer Helpdesk, who, in turn, sends a notification to the registered owner of the computer. The user is then responsible for contacting the Helpdesk to resolve the issue. This document outlines that notification process.
Please Note: While every attempt will be made to resolve the situation through this process, there may be instances where the availability, confidentiality, or integrity of the OSU network or the data residing therein is placed at risk by the activity discovered on the device. In such cases, network access for that system will be blocked prior to notification.
OSU notifies users when a malware infection is detected on their computer. Users must come in for help, or inform the Helpdesk that the infection has been removed.
Notifications include technical details on the infection and give users information on how to clean their own computers. Please note that the notifications will be from email@example.com and will be followed with an email from firstname.lastname@example.org detailing options you have to clean your computer.
Network access disabled notification:
If the user does not come in for help or notify the OSU Computer Helpdesk and they continue to receive notifications from email@example.com then the user’s network access will be disabled and a notification of the access restriction will be sent.
A user is not typically disabled until after three notifications have been sent, but there are circumstances that will extend the amount of notifications before loss of network access, such as a long period of time between malware notifications from FireEye.
Example Malware Notifications
Below are examples of the notification e-mails sent to users, which can be used as reference to ensure these are not fake emails or phishing attempts.

Example from the OSU Computer Helpdesk:
OSU’s Network Security group (firstname.lastname@example.org) sent you an e-mail recently informing you about a possible malware infection on your computer. The OSU Computer Helpdesk wanted to check in with you and see if you have been able to remove the infection.
Because network security is a priority for personal and network safety, careful procedures are in place to quarantine potential infections. If no response is received from you after multiple notifications, the Helpdesk will disable your network access. Multiple warnings will be provided before access is disabled and it is easy to restore your network access by contacting the Helpdesk to inform them you have cleaned the infection yourself, or for help removing the infection.
Please be aware that if you clean the infection yourself, you must inform the Helpdesk that the infection is resolved. If you don't respond to this email and your computer is still reporting as being infected, the Helpdesk will disable your network access after three notifications.
