    Be aware.

    Yesterday, while investigating some Facebook click-bait, I came across a fake Flash update that is targeting OS X users. Fake flash updates have been very common to infect OS X. They do not rely on a vulnerability in the operating system. Instead, the user is asked to willingly install them, by making them look like genuine Adobe Flash warnings (and we keep telling users to make sure Flash is up to date, so they are likely going to obey the warning and install the update).

    Would this have any effect on those that have removed Flash completely from their systems?

    I doubt it checks for an existing version of Flash at all, so yes. If you know you don't have Flash installed, it will be easier to avoid a fake "update" though :)

    Fake Flash warnings have been around for years. I've yet to come across one that looks like a genuine OS X dialogue box.

    The screenshot in the article shows a passable imitation. Possibly not good enough to fool you, but good enough for most of the target population.

    Excellent point. However it will fall on my deaf MR ear who believe anti-malware apps for OS-X are completely useless. Power to them but the target population is still at great risk and will be infected. Sad but true.
