#Has my computer been hacked file permission error word 2010 Patch#
Microsoft has repeatedly had to patch file format flaws in Office applications, most recently in July when it fixed a bug in Publisher 2007 and in June, when it patched seven vulnerabilities in Excel and two more in Word. "This is all driven by hackers using fuzzing tools," said Pescatore, talking about the dark art of hammering on file formats to probe for vulnerabilities. This allows you to look over the contents and make an informed decision if you really trust the file or not." "In Office 2010, we have removed this dialog and instead we now just open the file directly in Protected View. "It is extremely hard to answer this question without seeing the contents of the file first," acknowledged Malhotra.
Within Outlook, for example, users who open an attachment now face a dialog box that asks, "Would you like to open the file or save it to your computer?"
"If nothing else, we'll stay just as secure as before, but should cut down on the messages to the users," said Pescatore, talking about the kind of alerts current versions of Office display when users are about to open an untrusted document. "The file is being opened within a sandboxed instance of the application - Word, Excel, PowerPoint - and if there was malicious code present in the file, the goal is that code would not be able to find a way to tamper with your documents, change your profile or other user settings," said Vikas Malhotra, a Microsoft security program manager, in a entry to a company blog last week.
Protected View isolates Word, Excel and PowerPoint files in a read-only environment that prevents malware - which has piggybacked on Office documents for years - from harming the PC or hijacking the system.
