A new attack employs two separate pieces of malware, a malicious Word document and some techniques for maintaining persistence on compromised machines. The attack exploits a three-year-old vulnerability in the way that Office for Mac handles certain Word files. The content of the Word file is a rambling letter addressed to the United Nations Human Rights Commission and discussing the anniversary of the Tibetan uprising against China. It follows closely on the heels of a series of spear phishing attacks that targeted Tibetan non-governmental organizations last week.
