Trusteer Warns of Huge Security Hole on the Internet

80 Percent of Web Users are Vulnerable to Attacks that Exploit Flaw in Adobe Flash and Acrobat Software

NEW YORK--(, the customer protection company for online businesses, reported today that two weeks after Adobe released a critical patch for Flash and Acrobat Reader nearly 80 percent of Internet users are still vulnerable to attacks that exploit these vulnerabilities. These findings are based on more than 2.5 million users of the Rapport browser security service. This may be the biggest security hole on the Internet today, since 99 percent of Internet users are using Flash in their browsers (

A report released today by Trusteer found that among the 2.5 million Internet banking users in North America and Europe protected by its Rapport security service, 98.8 percent have Flash active in their browser. From this sample, 80 percent were running outdated and unpatched versions of Flash, while 84 percent were running a vulnerable version of Acrobat. The full report is available at

From a security avoidance standpoint Flash and Acrobat are the ultimate platforms for distributing malware. Targeting vulnerabilities in these applications is extremely efficient since it enables criminals to target 99 percent of Internet users. By comparison, targeting vulnerabilities in Internet Explorer only reaches approximately 65 percent of Internet users. While Firefox-based attacks only reach 30 percent.

“Adobe is facing some major security challenges and one of its biggest hurdles is its software update mechanism. For some reason, it is not effective enough in distributing security patches to the field,” said Mickey Boodaei, CEO of Trusteer. “Given the lack of attention this situation has received to date, it appears that few people understand the magnitude of the problem. We recommend that all enterprises and individuals install the latest Flash and Acrobat updates immediately.”
