An Italian researcher from the security firm InTheCyber devised an attack technique to create self-replicating malware hidden in MS Word documents. Lino Antonio Buono has devised the attack vector to bypass the security control implemented by Microsoft. Microsoft doesnt consider the issue a security vulnerability, but Microsoft explained that the feature exploited by the Italian researcher was implemented to work exactly in this way. The worst news is that crooks are already exploiting the same attack vector devised by Buono.”]
