Superfish: The Hijacker

Superfish just captures the SSL traffic. How does it do so? A self-generated root certificate is installed in the Windows Certificate store that is reserved. This reserved location consists of certificates from Microsoft and Verisign. The adware resigns these SSL certificates that have been assigned by HTTPS sites with its own generated and signed certificates.

Superfish thereby conducts a man-in-the middle attack and breaks the security layer of HTTPS encryption. It is also believed that simply removing this adware does not remove this culprit completely. Microsoft has a Windows Defender Update that removes adwares. That certificate may be revoked manually.

Hers is how you can do it:

Press Windows key and R on you keyboard to bring the Run tool.

  • Look for certmgr.msc and open your PC’s Certificate Manager
