What You Need to Know About the Security Risks of Adobe Flash

Dec 10, 2020

By now you’ve likely heard that Adobe is ending its support of Flash on December 31, 2020. In fact, Adobe released the last ever Flash update today, December 10, 2020. With this update, Flash will no longer play content after January 12, 2021. 

You might be thinking “Perfect! I don’t publish anything with Adobe Flash anymore and Flash playback will be blocked on my computer, so I don’t need to do anything.” But just ending Flash usage isn’t enough. Adobe also recommended in today’s update that you uninstall Flash Player entirely. Here’s why . . .

We’ve shared a bit about the history of Adobe Flash, but, suffice to say, Flash’s multiple security vulnerabilities left it ripe for being overtaken by a new, more secure solution (in this case, HTML5).

Even when dormant, just having Adobe Flash on your computer leaves it open to being hijacked by malicious code embedded in websites. When these exploits run, they can automatically redirect your browser to sites that install further malware and compromise your machine. 

If you have Flash installed on your computer, you’ve probably seen a pop-up from Adobe offering to uninstall it. You might be a little nervous uninstalling something that’s camped out on your hard drive for so long. But it’s OK. Articulate 360 apps and Storyline 3 don’t use Flash, so any training you create isn’t affected by Adobe sunsetting Flash. 

However, if you’re using one of these legacy Articulate products: Storyline 1, Storyline 2, Studio ’09, or Studio ’13, click here for more information on how the end of Adobe Flash will affect you. Long story short, if you have content that was previously published in Flash and you want your learners to be able to keep using it past December 31, 2020, you’ll need to republish it as HTML5. 

Throughout 2020 we’ve been sharing helpful content and resources to help you prepare for the end of Adobe Flash. Catch-up on everything we’ve shared so far and keep tabs on the latest information on this topic by visiting and bookmarking our series, Preparing for the End of Adobe Flash

Hi Indrani,

All of the Articulate 360 apps (including Studio 360) no longer rely on Flash to run - so your authoring experience should continue to be smooth and seamless.

Also, be sure you're publishing your courses for HTML5 so that learners can continue to access the content in their browsers.

Hello Wei Jing,

I'm not clear if you cannot open your published files or your software, so I'll respond to each option:

  • The HTML5 output from Studio ‘13 works in Google Chrome and Safari. However, it won’t work reliably in other browsers.
  • Studio '13 relies on Flash to operate, so we do recommend upgrading.

The following article outlines all of these details:
