Researchers this week published information about a newfound, serious weakness in WPA2 — the security standard that protects all modern Wi-Fi networks. What follows is a short rundown on what exactly is at stake here, who’s most at-risk from this vulnerability, and what organizations and individuals can do about it.
This author has long advised computer users who have Adobe’s Shockwave Player installed to junk the product, mainly on the basis that few sites actually require the browser plugin, and because it’s yet another plugin that requires constant updating. But I was positively shocked this week to learn that this software introduces a far more pernicious problem: Turns out, it bundles a component of Adobe Flash that is more than 15 months behind on security updates, and which can be used to backdoor virtually any computer running it.
Researchers have uncovered an extremely critical vulnerability in recent versions of OpenSSL, a technology that allows millions of Web sites to encrypt communications with visitors. Complicating matters further is the release of a simple exploit that can be used to steal usernames and passwords from vulnerable sites, as well as private keys that sites use to encrypt and decrypt sensitive data.
On Thursday, the world learned that attackers were breaking into computers using a previously undocumented security hole in Java, a program that is installed on hundreds of millions of computers worldwide. This post aims to answer some of the most frequently asked questions about the vulnerability, and to outline simple steps that users can take to protect themselves.
