Excels also encountered "zero-day attacks," the threat of

Microsoft, by the "zero-day attacks," the threat of a general increase. On February 2,Microsoft also issued another on the Office 2010 download Excel's security alerts, the current threat has not been widespread concern.

In its security bulletin said: "Some office applications in a potential threat." "Zero-day attacks," the damage is not repaired, the attack is on Microsoft EXCEL since Decemberby the fifth attacks, the threat of further growth trend of the range.

"Zero-day attacks," the threat affects Office 2010, Office XP, Office2003 and Office2004,Office2007 and but for Works 2004, Works 2005 orWorks 2006 has no effect. An attacker exploit the vulnerability can be user clicks the master page file or intercepted e-mail regularly, but also can promote end-user communication.'s Biggest threat comes from the user to run administrative privileges. Successful hacker can get access to information the user's permission, and the installation of the system to Windows VistaOffice software is difficult to be attacked, because all of the users and even system administrators are operating in standard mode. Microsoft recommends that before thepatch, users avoid opening do not know the person who sent the e-mail is not reliable.

Security software developers are constantly studying the serious defects. February 6 atthe RSA Conference, CA announced a series of prevention system to system tools to resist the "zero-day attacks," the threat. Marketing Manager David Finger said, "zero-day attacks," the virus now has a virus variants, we can use many tools to detect it.

"Zero-day attack" vulnerability is currently the primary software security issues, as part of the security signature has been developed to a certain extent, the time is another factor,because the patch trying to solve the security problem has become obsolete. To taketough measures against attacks, "zero-day attacks" against the attacks of EXCEL is a good example.
