PC PhoneHome

PC PhoneHome is software that can help recover a lost or stolen laptop. Columbia University has purchased a site license for PC PhoneHome from Brigadoon Security Group.

PhoneHome is an application which runs silently on Windows and Macintosh computers, sending information to Brigadoon Security Group whenever a network connection is made. This information is only accessed if the machine is reported stolen. In this case, Brigadoon shares the appropriate information (IP address, time) with law enforcement officials who attempt to recover the machine. 

Since PhoneHome is designed to be undetectable, there is no sure way for a user to verify that it is running. 

If you want to remove PCPhoneHome from your laptop, contact the CUIT Computing Support Center to make an appointment to bring your machine to 202 Philosophy Hall. If you cannot come to campus, or if your machine is not a laptop, notfity the Support Center of that and a technician will contact you to assist in removing the product.

If you want to remove MacPhoneHome from your computer, you will need to contact Brigadoon to request a customized installer. Be sure to include complete indentifying information in your request, such as your full name, Unique ID and address and an email address where your uninstaller can be emailed. As Columbia's email system does not accept file attachments in .exe format, you should specify a separate address, such as a Yahoo or Gmail account to receive this email.

If your machine is stolen, you should notify Columbia Public Safety immediately and inform them that you have installed PhoneHome. 

If your laptop is administered by your department, you should speak to your system administrator before installing software like PC PhoneHome.

PC PhoneHome Stolen Computer

If you have installed PhoneHome on a machine and that machine is stolen, you should notify Columbia Public Safety immediately, even if the theft did not occur on campus. Make sure you mention that PhoneHome is installed. 

You do not need to contact Brigadoon Security Group. Columbia Public Safety will notify them of the theft reported, and will speak with Columbia University IT Security if more information is required.

Once Brigadoon has been notified, they will contact law enforcement in the area that your machine has been seen since the theft and provide technical assistance to help them recover the machine. Once law enforcement officials have recovered it, they will turn it over to Columbia Public Safety.

The process is much easier if you can present Public Safety with some information about the machine at the time of the report. Knowing the MAC address of network cards and the serial number of the machine can expedite the process of getting your computer back returned.
