Do you still surf the Web with Internet Explorer?  If so, you’re not alone. Even after Microsoft came out with their new Edge browser in 2015, some people are still using Internet Explorer.

The Problem?

Security experts have found serious security flaws in Internet Explorer’s code. This means that if you use it, you’re opening yourself and your business up to hacking and computer viruses.

Another Problem?

Microsoft won’t be fixing this for the foreseeable future.

What Are These Flaws?

The most recent of these was found by an independent researcher named John Page. He published a proof of concept that demonstrates a flaw in the way that Internet Explorer handles MHT files. MHT is a Web page archive file format.

How Do These Flaws In Internet Explorer Create Security Issues?

If you use Windows 7, Windows 10, or Windows Server 2012 and it comes across an MHT file, it will try to open the file using Internet Explorer. This presents an easy opportunity for savvy hackers.  All they have to do is to use an MHT file containing a malicious virus and present it to you via a phishing email or other form of social engineering. Once you take the bait, the malicious virus gets into your computer/server.

Are We Safe If We Use Another Type Of Browser?

Not really. Any Windows-based system is still very much at risk from infected MHT files. This is because Internet Explorer 11 still ships with all Windows-based PCs. This includes computers that use Windows 10.

What Can We Do To Prevent Being Hacked Due To Internet Explorer Flaws?

One good thing is that Internet Explorer isn’t enabled on Windows 10 computers. For it to be enabled, you need to set it up yourself.

For now, this is the simple solution — Just don’t enable Internet Explorer. And to be completely sure, it’s best if you uninstall Internet Explorer from your Control Panel altogether.

John Page reported the issue to Microsoft on March 27, 2019, and received the following reply from them:

“We determined that a fix for this issue will be considered in a future version of this product or service. At this time, we will not be providing ongoing updates of the status of the fix for this issue, and we have closed the case.”

Unfortunately, it looks like, for the foreseeable future, that Microsoft won’t be providing a fix regarding the flaws with Internet Explorer. As we said above, the answer, for now, is for you and your staff to uninstall Internet Explorer from your computers.
