I like this statement from the Apple Insider article:
"As a general rule, nobody should be installing Flash Player in 2019 — not even the real, legitimate one," Intego commented. HTML5 and other technologies have made Flash obsolete, and Adobe itself is ending development and distribution of Flash Player by the end of 2020. The plugin was disabled by default in 2016's macOS Sierra, and has never been available in iOS.
IMO that is the best approach to Flash or Flash Player.
RELATED TOPIC- Yesterday I received an email purportedly from a vendor I had recently ordered from inviting me to participate in a survey and get a prize. On the face it appeared legitimate but there was something not quite right about it. So I opened the message in raw format and found it was mostly Javascript and included a page and a half of totally unrelated text from only the creator knows where. I attempted to analyze the Javascript but gave up because the code was incredibly baroque. And the purported sender denied any knowledge of the message or the survey. At this point the surmise is clicking on the survey link in the message exposes you to a Windows malware exploit. I am not going to risk clicking to find out. I forwarded the message to the purported sender and they took it from there. In the meantime I immediately deleted the message, emptied the trash, and increased the rate of MalwareByte's scans.
- I have no idea what the average internet user would do in a case like this. Even if they are astute enough to pick up on the content clues I saw, much less knowledgable enough to open the message in raw mode, I venture less than 30% of Mac users and 5% of iOS users would have any idea how to interpret what they were seeing.
THE INTERNET HAS BECOME A HOSTILE ENVIRONMENT
