If you needed another reason not to use Flash anymore, a new security report by Recorded Future may convince you to consider this at the very least.
The company analyzed 141 exploits kits that were available between November 16, 2015 and November 15, 2016.
The main takeaway of the research study is that Adobe Flash vulnerabilities made up six of the top ten chart spots.
Flash was not the only software that exploit kits targeted in the past year though. In fact, a vulnerability in Microsoft Internet Explorer tops the chart, followed by three Flash vulnerabilities and then a Microsoft Silverlight vulnerability.
A Windows vulnerability comes in at seven, and another Internet Explorer vulnerability at nine. The remaining places are all filled by Flash vulnerabilities
Flash did better this year than last year. Last year, Flash topped the first eight places of the top ten vulnerabilities list used by exploit kits, with Internet Explorer and Silverlight taking up the last two spots.
As far as the methodology is concerned that Recorded Future used to generate the report: it did not reverse engineer exploit kits or use other forms of direct analysis. Instead, it used meta information available on the Internet to compute the information.
Recorded Future did not reverse engineer any malware mentioned in this analysis and instead performed a meta-analysis of available information from the web. Exploits for dozens of other vulnerabilities are currently employed by EKs and this report’s intent is to highlight top targets of popular exploit kits.
This means that the vulnerabilities are not necessarily graded by severity, or impact on user systems. Instead, the vulnerabilities are graded by references made to them on security sites, forums and such.
This can be easily seen by looking at the vulnerability adoption by exploit kit chart that the company created.
While the first five vulnerabilities listed were all exploited by three or four exploit kits, it was the Flash vulnerability in the tenth spot that was exploited the most (seven times).
The report ends with recommendations. These include the usual: patch your system and software, remove software if it is not required for core business processes, enable click to play, use script blockers, create frequent back ups, and use Chrome if possible.
