You Might Be Vulnerable To Hackers Because You Have These Microsoft Office Program In Your Computer

On the 13th of December 2016, it was discovered that
  • Microsoft Excel 2007 SP3
  • Microsoft Excel 2010 Service Pack 2 (32-bit editions)
  • Microsoft Excel 2010 Service Pack 2 (64-bit editions)
  • Microsoft Excel 2013 RT Service Pack 1
  • Microsoft Excel 2013 Service Pack 1 (32-bit editions)
  • Microsoft Excel 2013 Service Pack 1 (64-bit editions)
  • Microsoft Excel 2016 (32-bit editions)
  • Microsoft Excel 2016 (64-bit editions)
  • Microsoft Excel 2016 for Mac
  • Microsoft Excel Viewer
  • Microsoft Office Compatibility Pack Service Pack 3
were all prone to hackers attacker, because they have a bug called Microsoft Office CVE-2016-7266.

This bug is a remote execution vulnerability that can enable and attacker leverage this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely result in denial-of-service conditions.

But do not despair, you do not have to wait for an official patch before you can prevent impending attacks, you can do that now, and what you need to do to protect yourself from this are:
  • Block external access at the network boundary, unless external parties require service.
    Filter access to the affected computer at the network boundary if global access isn't required. Restricting access to only trusted computers and networks might greatly reduce the likelihood of exploits.
  • Deploy network intrusion detection systems to monitor network traffic for malicious activity.
    Deploy NIDS to monitor network traffic for anomalous or suspicious activity. Monitor logs generated by NIDS and by the server itself for evidence of attacks against the server.
  • Do not accept or execute files from untrusted or unknown sources.
    To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
  • Permit privileged access for trusted individuals only.
    Permitting access to vulnerable applications for trusted individuals only can reduce the risk of an exploit.
I just came across this in one of the post in Symantac and decided to share it with you so that you can protect yourself.

I also advice that you should refer to the Official Microsoft and Microsoft Office Product website for more information and updates regarding this issue.
