Twitter vulnerable to XSS worm attack

By Robert McMillan, ComputerWorld

Computer security researchers have devised a new Twitter attack that they say could spread virally, much like a worm on the microblogging service.
The attack, publicized by researchers at Secure Science, is an innocuous proof-of-concept that forces users to send out a predetermined Twitter message, but it could be repurposed into a very nasty worm, said Lance James, chief scientist at Secure Science.
“You can couple an attack with our code and it would just tear the crap out of Twitter,” he said.

Q&A: CanSecWest hacker Charlie Miller

At the CanSecWest security conference in Vancouver BC, I got a chance to sit down with Charlie Miller, the researcher who won the Pwn2Own hacking contest by exploiting a fully patched MacBook Air machine using a Safari code execution vulnerability.
We discuss the state of Web browser security, the marketplace for software vulnerabilities and the need for better anti-exploit mitigations on modern operating systems.

Non-profit group launches badware-busting community

The backers of the non-profit StopBadware.org consortium have launched a Web site where ordinary people can band together to fight computer viruses and adware. The online community site, called BadwareBusters.org, launched Tuesday and is sponsored by Harvard University’s Berkman Center, which runs StopBadware.org, and Consumer Reports WebWatch, an online information source for Web users.

CanSecWest, in beautiful Vancouver BC, is one of my favorite conferences each year. It’s a cozy little security con that brings together security researchers from all parts of the security ecosystem. Like a PhNeutral or a BlueHat, one never quite knows what to expect out of a CanSecWest, but we do know that Microsoft products and engineers will play a prominent role. We’ll be presenting new security innovations and new tools, we’ll be watching Pwn2Own closely for possible hacks, and we’ll be happy to discuss our industry best practices in the hallway track.

We recently conducted a project focused on confidential data security [enterprisestrategygroup.com] that will be published soon. However, here are some interesting advance results that support this venerable security dictum. ESG asked 308 North American and European security professionals from large organizations (i.e. 1,000 employees or more) a number of questions about data security risks, policies, and technology safeguards. When asked to define the most important measures for protecting confidential data, nearly half of all respondents said, “communicating and training users on confidential data security policies.” This was the top response followed by, “physical security,” and “access controls for private data.”

Welcome to the Show – Mon, October 20 2008

In this show, we introduce ourselves and recap the Virus Bulletin 2008 conference. We talk about the MBR Trojan (bootkit), the controversy surrounding anti-virus testing standards, information on the blackmarket for online gaming passwords and some data from Microsoft’s malicious software removal tool (MSRT).

In an ironic twist, Kevin Mitnick, a social engineering master who went to jail for impersonating others to get information to access computer networks without authorization, couldn’t access his own Facebook account for weeks because administrators at the social networking site didn’t believe he was who he said he was.

In this Network World interview at SOURCE Boston, well-known hardware hacker Joe ‘Kingpin’ Grand talks about lessons rom the “Prototype This” show, the changing face of security research and his upcoming vulnerability assessment work.  The video also includes an interview with Dan Kaminsky about his DNS vulnerability.
