Google slams AVG for exposing Chrome user data with "security" plugin
http://arstechnica.com/security/2015/12/google-slams-avg-for-exposing-chrome-user-data-with-security-plugin/ A free plugin installed by AVG AntiVirus bypassed the security of Google's Chrome browser, potentially exposing the browsing histories and other personal data of customers to the Internet. The vulnerability, demonstrated in an exploit by a Google researcher earlier this year, has now been patched after initial stumbling attempts by AVG, according to a discussion of the bug in Google's security research discussion list. AVG's "Web TuneUp" tool is a free download from the Chrome Store intended to provide reputation-based protection against malicious websites, and it was "force-installed" by AVG AntiVirus in a way that broke the security checks Chrome uses to test for malicious plugins and malware. The plugin works by sending the Web addresses of sites visited by the user to AVG's servers to check them against a database of known malicious sites. But the way the plugin was constructed meant that information could be easily exploited by an attacker through cross-site scripting [XSS], according to a post by Google Security researcher Tavis Ormandy on December 15. - - - Executive summary: Uninstall any and all of this AVG crap you have around. --Lauren-- Lauren Weinstein ([email protected]): http://www.vortex.com/lauren Founder: - Network Neutrality Squad: http://www.nnsquad.org - PRIVACY Forum: http://www.vortex.com/privacy-info Co-Founder: People For Internet Responsibility: http://www.pfir.org/pfir-info Member: ACM Committee on Computers and Public Policy Lauren's Blog: http://lauren.vortex.com Google+: http://google.com/+LaurenWeinstein Twitter: http://twitter.com/laurenweinstein Tel: +1 (818) 225-2800 / Skype: vortex.com I have consulted to Google, but I am not currently doing so -- my opinions expressed here are mine alone. _______________________________________________ pfir mailing list http://lists.pfir.org/mailman/listinfo/pfir
