Windows Defender Vulnerability

windows security

April 4, 2018, 08:18(EDT) By Eric (a.k.a. TweakHound)

I’m in front of the boob tube last night and I get this email entitled “Microsoft Security Update Releases” (full email posted below).
CVE-2018-0986 | Microsoft Malware Protection Engine Remote Code Execution Vulnerability
The gist of the alert is that all versions of Windows Defender have a vulnerability.
If Windows Defender scans an infected file then a hacker could own your system.
Rephrased…
If the product that is supposed to protect your system just SCANS a bad file you could be OWNED.
Fortunately this has been patched. Windows Defender should update automatically but you can force an update.
Press the Windows + R keys > copy paste the following: “%ProgramFiles%\Windows Defender\MSASCui.exe” -Update

Hash: SHA256

    That’s interesting. Only last week I disabled Windows Defender in Local Group Policy (I have other security layers).

    I’m glad I disabled it after reading this!
