Google and Mozilla each announced this week that their Web browsers will be dropping default support for Adobe Flash, citing the plug-in software?s newly discovered vulnerabilities to cyberattacks. These moves came only a few days after Facebook?s chief of security called for Adobe to set an ?end of life? date for the oft-exploited 20-year-old platform.
Even if you don?t exactly know what Adobe Flash is, this is important news. Whether you know it or not, odds are pretty high that Adobe Flash is on your computer right now, possibly putting your system and your personal information at risk.
Don?t panic. Take a deep breath and read our Adobe Flash security threat guide. We?ll help you figure out why it might be best to banish Flash from your life, just like Google, Mozilla, and Facebook want you to do. And we?ll tell you how to go about doing exactly that.
So what is Flash, exactly?
Adobe Flash is a software platform that runs video, animation, and games inside of Web pages. Flash was born at the dawn of the Web in 1996 and quickly became the standard for Web video, especially after a little startup called YouTube began using it in 2005. But now it?s largely obsolete, as most Web sites and apps use different technologies for the same purpose.
Why is Flash a problem?
The very thing that made Flash so popular ? its ability to run complex scripts from websites you visit ? can also be used for malicious purposes.
Computer scripts written in Flash can directly access the memory on your computer, which is just inviting attacks, or ?exploits,? says Chase Cunningham, a cyberthreat expert at security company FireHost. ?Anytime a site is able to access your computer?s memory, it?s able to make changes on the local machine itself [your PC]. That?s when you run into exploits.?
Flash has long been one of the biggest attack methods of choice for cybercrooks and spying governments, as security vulnerabilities turn up on an almost daily basis. Just this month, Adobe put out security alerts and fixes for 38 vulnerabilities in Flash Player. Last week, it came out that a company called Hacking Team had been using previously unknown flaws in Flash to create spyware that it sold to oppressive governments in countries such as Sudan and Saudi Arabia.
Flash also uses up a lot of computing resources and can bog systems down. ?We ? know firsthand that Flash is the number one reason Macs crash,? wrote Steve Jobs in an Apple blog post from April 2010.
