Disable Adobe Flash Now Otherwise Your Cyber Attack Risk Will Be Much Greater – Charles Leaver

Be Strong or Get Attacked.

Extremely knowledgeable and skilled cyber attack groups have actually targeted and are targeting your business. Your huge endpoint population is the most typical point of entry for skilled attack groups. These business endpoints number in the thousands, are loosely handled, laxly set up, and rife with vulnerability exposures, and are operated by partially trained, credulous users – the perfect target-rich chance. Mikko Hypponen, chief research officer at F-Secure, often remarks at industry seminars: “How many of the Fortune 500 are hacked right now? The answer: 500.”

And how long did it take to penetrate your organization? White hat hackers carrying out penetration testing or red group workouts usually compromise target enterprises within the first few hours, even though ethically and legally limited in their approaches. Black hat or state sponsored hackers might attain penetration even more rapidly and protect their presence indefinitely. Given average cyber attacker dwell duration’s determined in numerous days, the time-to-penetration is negligible, not an impediment.

Exploitation Packages

The industrialization of cyber attacks has actually developed a black market for attack tools, consisting of a variety of software for recognizing and exploiting client endpoint vulnerabilities. These exploit packages are marketed to cyber hackers on the dark web, with lots of exploit package families and suppliers. An exploit set runs by evaluating the software application setup on the endpoint, recognizing exposed vulnerabilities, and using an exploitation to a vulnerability direct exposure.

A relative handful of commonly released endpoint software applications accounts for the bulk of exploitation package targeted vulnerabilities. This arises from the sad reality that complex software applications tend to display a continuous flow of susceptibilities that leave them continuously vulnerable. Each patch release cycle the exploit kit developers will download the current security patches, reverse engineer them to discover the underlying vulnerabilities, and upgrade their exploit packages. This will frequently be done quicker than organizations apply patches, with some vulnerabilities staying unpatched and ripe for exploitation even years after a patch is issued.

Adobe Flash

Prior to prevalent adoption of HTML 5, Adobe Flash was the most typically used software application for rich Web content. Even with increasing adoption of HTML 5, legacy Adobe Flash keeps a considerable following, preserving its long-held position as the darling of exploitation package authors. A current research study by Digital Shadows, In the Business of Exploitation, is explanatory:

This report analyzes 22 exploit packages to understand the most regularly exploited software applications. We looked for trends within the exploitation of vulnerabilities by these 22 sets to show what vulnerabilities had been exploited most commonly, paired with how active each exploit set was, in order to inform our evaluation.

The vulnerabilities exploited by all twenty two exploitation sets showed that Adobe Flash Player was most likely to be the most targeted software, with twenty seven of the 76 recognized vulnerabilities exploited pertaining to this software application.

With relative consistency, lots of fresh vulnerabilities are revealed in Adobe Flash each month. To exploitation set developers, it is the present that continues giving.

The industry is discovering its lesson and moving beyond Flash for rich web material. For instance, a Yahoo senior developer blogging recently in Streaming Media kept in mind:

” Adobe Flash, in the past the de-facto requirement for media playback on the web, has actually lost favor in the market due to increasing concerns over security and performance. At the same time, needing a plugin for video playback in internet browsers is losing favor among users as well. As a result, the market is moving toward HTML5 for video playback.”

Eradicating Adobe Flash

One action organizations may take now to harden their endpoint configurations is to eliminate Adobe Flash as a matter of organization security policy. This will not be an easy task, it might hurt, however it will be valuable in minimizing your organization attack surface area. It involves blacklisting Adobe Flash Player and imposing web browser security settings disabling Flash material. If done correctly, this is what users will see where Flash material appears on a legacy website:


This message verifies two facts:

1. Your system is correctly set up to decline Flash content.

Congratulate yourself!

2. This website would compromise your security for their benefit.

Ditch this site!
