If you have Adobe Flash Player, your computer may be attacked

computer virus

There are over a billion users of Adobe Flash Player–a free software for using content created on the Adobe Flash platform, including viewing multimedia, executing rich Internet applications, and streaming video and audio.

Yesterday, Adobe issued a security advisory that its Flash Player software has a “critical vulnerability” that “is being actively exploited” to deliver ransomware to computers with Windows 10 (and earlier), Macintosh, Linux and Chrome OS.

NoteRansomware is a type of malware that restricts access to the infected computer system in some way, and demands that the user pay a ransom to the malware operators to remove the restriction. Some forms of ransomware systematically encrypt files on the system’s hard drive, which become difficult or impossible to decrypt without paying the ransom for the encryption key, while some may simply lock the system and display messages intended to coax the user into paying. Ransomware typically propagates as a trojan, whose payload is disguised as a seemingly legitimate file.

Adobe warns: “Successful exploitation [of the Flash Player’s vulnerability] could cause a crash and potentially allow an attacker to take control of the affected system.”

Adobe recommends users of Adobe Flash Player, who have not already done so, immediately update to the current version of Flash Player via the update mechanism within the product or by visiting the Adobe Flash Player Download Center.  If you use multiple browsers, install the update in each browser you have installed on your system.

  1. So the Microsoft Emperor has no clothes, and all his tens of billions cannot save us users from this patheic incursion? Why would anyone in his/her right mind buy anything from him, nor listen for words of guidance?

    Lame, lame, lame! Out to the back forty, & bring him home as a roast!

  2. Dr Eowyn . . . what would we do if we did not have you looking out for us? I followed the instructions you gave in this article, and I must say I feel more at ease over being able to fix the Adobe Flash Player problem.

    Many thanks to you!

  5. Personally I can’t say this is a surprise since flash itself is a virus/exploit essentially, its a shoddy memory hog utilized to data mine & track people through it’s own version of “cookies” that aren’t regularly recognized by more rudimentary cookie handlers built into systems. Its better to disable any browser plug-ins that may utilize it if you don’t use the thing. Unfortunately the majority of the public domain has not yet recognized flash is trash and java is junk, and continue to use them. The NSA must be overjoyed.

    Aside from patching it though, if you don’t actually use flash for anything, like playing games, watching videos or rendering stuff, the best idea is to just rip that monster out of your system entirely. If you do use it, a good idea is to at least have a plug-in/extension/add-on called “Flashblock” installed ( here: https://addons.mozilla.org/en-US/firefox/addon/flashblock/ ) or another flash controller for your particular browser, as well as an ad blocker like “adblock” or “ghostery”, ‘course if you don’t mind taking more drastic control “NoScript” ( https://noscript.net/faq ) is an option. (And myself personally, I also found a CSS disabler… those “sponsored results” that google and other search engines jam into pages can similarly be stopped from displaying, by blocking those pages CSS/Cascading Style Sheets)

    Its also a good idea to use different browsers for different things. (there are more out there than just firefox, chrome, safari, and IE after all, there is slimboat, and sleipnir [IE-type], comodo dragon [chrome-type] and ice dragon [firefox-type] and Opera is still around as well, there is also avant browser which is basically all three browser engines in one. One Caveat, newer programs seem to auto-update by default without end-user permission, like “Ice Dragon”, be sure to try to reign in these program’s auto-update and recommended update features by disabling them or setting them to manual, where possible.)

    Apparently there is a third option, that of running your browser in a “sandbox”, I don’t know how best to describe it, but “sandboxie” is one program for it that I’ve heard good things about (This is an intro and guide for it: http://www.techsupportalert.com/content/introduction-and-quick-guide-sandboxie.htm )

    Finally, having a firewall, anti-virus, and a blocking program (like “PeerBlock”) is also a good idea to help keep your ‘net guard up.
