Sony used software known as a root kit to cloak applications on users computers. The package automatically installed when CDs were played on Windows computers, spying on users and restricted how they used music they had purchased. By installing a root kit on users computers, Sony created an area for hackers to hide their own malicious applications.

The proposed FTC settlement requires clear and prominent disclosure on the packaging of Sony BMG’s future CDs of any limits on copying or restrictions on the use of playback devices. It also bars it from using collected information for marketing, prohibits it from installing software without consumer consent and requires it to provide a reasonable means of uninstalling that software.{moscomment}
