A Remote Vulnerability in Firefox Extensions

Christopher Soghoian is reporting that many popular Firefox extensions like Google Toolbar, Google Browser Sync, Yahoo Toolbar, Del.icio.us Extension, Facebook Toolbar, AOL Toolbar, Ask.com Toolbar, LinkedIn Browser Toolbar, Netcraft Anti-Phishing Toolbar, PhishTank SiteChecker and a number of others, mainly commercial have vulnerability in the upgrade mechanism.

Users are vulnerable and are at risk of an attacker silently installing malicious software on their computers. This possibility exists whenever the user cannot trust their domain name server (DNS) or network connection. Examples of this include public wireless networks, and users connected to compromised home routers.

Here’s a video demo of the attack against Google Browser Sync. It is recommended to disable or delete insecure extensions from your browser until there’s a fix.

China Crafts Cyberweapons

US Defense Department reports that China is preparing for cyberwarfare by developing viruses and training more seriously for computer attacks. The main target is of course Taiwan, but since US would intervene in case of such attack, so US is a potential target too.

“The PLA has established information warfare units to develop viruses to attack enemy computer systems and networks,” the annual DOD report on China’s military warned. At the same, Chinese armed forces are developing ways to protect its own systems from an enemy attack, it said, echoing similar warnings made in previous years.

Cain & Abel

Cain-AbleCain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol’s standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources, however it also ships some “non standard” utilities for Microsoft Windows users.

Security Report: Windows vs Linux

An independent assessment of Windows vs. Linux. Microsoft Windows Server 2003 vs. Red Hat Enterprise Linux AS v.3 were examined to see which platform is more secure.

The results were not unexpected. Even by Microsoft’s subjective and flawed standards, fully 38% of the most recent patches address flaws that Microsoft ranks as Critical. Only 10% of Red Hat’s patches and alerts address flaws of Critical severity. These results are easily demonstrated to be generous to Microsoft and arguably harsh with Red Hat, since the above results are based on Microsoft’s ratings rather than our more stringent application of the security metrics. If we were to apply our own metrics, it would increase the number of Critical flaws in Windows Server 2003 to 50%.
