Computer Security: Flash, as bad as bad can be

This year, the Adobe Flash Player made it to number 1 in the charts of ways your PC or laptop could be compromised

|

Being flashed by a speed camera on the motorway is a nuisance but it’s usually your fault, you were speeding, and it looks like using Adobe Flash on your computer nowadays can cause a similar blunder. This year, the Adobe Flash Player made it to number 1 in the charts of ways your PC or laptop could be compromised.

Just recently, another vulnerability for Flash was reported, affecting all operating systems: Windows, Mac, Linux and Chrome OS. One vulnerability to rule them all – the main reason why Flash topped the charts at number 1. The first exploits abusing this vulnerability have been already reported and it is now up to all of us to fix our operating systems ASAP. As usual, owners of CERN centrally managed Windows PCs don’t need to worry. Their PCs will have this fix automatically deployed.

But more generally, why do we still stick with Flash? Its time has passed and it is being superseded by the more fancy and modern HTML5. The IT department is therefore actively eliminating any requirement for it in central services and considering dropping the installation of Flash from all of its centrally managed PCs. And since they are already at it, Adobe’s Acrobat Reader, which is also a prominent member of the Top 10 vulnerabilities, might be phased out too. Of course there will be suitable alternatives offered for both. So, why would you still need Flash for professional purposes? Send us your opinion using the links below:
