Under intense media and consumer pressure, Sony has agreed to recall 2 million CD’s bacuse of a malicious software anti-piracy measure. “Sony BMG has used the XCP copy-protection software on 49 titles from artists such as Celine Dion and Sarah McLachlan and produced an estimated 4.7 million music CDs. Around 2.1 million units have been sold on to consumers. The software, developed by a British firm, First4Internet, installs itself on a personal computer used to play the CD in order to guard against copying, but it leaves the back door open for malicious hackers.”
