Acrobat Reader X delivers on security promise

Over at the Naked Security blog, Sophos Labs' Paul Baccas posted his first encounter with PDF spam using Adobe Reader X -- which Adobe promised would feature an improved set of security features. Baccas was examining a new spam campaign which aims to trick users into opening a malicious PDF, first opening it in Reader 8 and then in Reader X.

When opened in the old version, the PDF attack mechanism springs into action and downloads malicious code from a remote server. Under Reader X, however, all he saw was the dialog above. "It appears that an update introduced in Adobe Reader X has broken a fundamental part of this threat. Well done Adobe!" says Baccas.

We're also in agreement with his recommendation that everyone who can -- network administrators included -- update their systems to Adobe Reader X as soon as possible.
