A couple days after a new install of windows 10 and an install of Adobe Reader I got a message stating my Adobe Flash Player might be out of date. I clicked the update, not thinking I never installed Flash Player. When the update started, it was pinging ingaiccin.com. Is this legit or have I been hacked?? A command prompt window was open during the update process.
That doesn't answer the question
The update you are seeing is not from a legitimate source. All updates for Flash Player will be from get3.adobe.com url. We will forward the url to the phishing team. Please do not update Flash Player using the above link.
As to your query that you have not installed Flash Player, Windows 10 comes with pre-installed Flash Player(for IE and Edge browsers) and all updates are pushed by Microsoft as part of Windows update. In case you install Flash Player for Firefox or Opera browsers you will be prompted for updates if you are not selecting Silent Updates.
