Users from Vietnam, India, China, Taiwan and possibly other countries, were targeted as part of an attack campaign that uses Microsoft Word documents rigged with exploits in order to install a backdoor program that allows attackers to steal information, according to researchers from security firm Rapid7. One of the malicious documents found by Rapid7 researchers is written in Vietnamese and is about best practices for teaching and researching scientific topics. This suggests that the targets of attacks where this document was used are part of the Vietnamese academic community, Rapid7 researchers Claudio Guarnieri and Mark Schloesser said Friday in a blog post. Identified as CVE-2012-0158 and CVE-2012-1856, respectively, these vulnerabilities affect Microsoft Office 2003, 2007 and 2010, and were patched by Microsoft in 2012 as part of the MS12-027 and MS12-060 security bulletins.
