Mobile Security Woes Go Beyond Malicious Apps

If, like most Americans, you’ve developed an attachment to your mobile phone that borders on the unnatural and have a hard time going 11 seconds without checking email or texts, you’d do well not to attend a talk by Zach Lanier and Mike Zusman anytime soon. The pair discussed a variety of weaknesses in several mobile platforms and showed off enough clever attacks in their talk at SecTor in Toronto last week to make the listener want to pull the SIM card from his phone, set it down and back quietly away.

Expert Advises Caution on SCADA Security Hysteria

TORONTO–The months-long hysteria over Stuxnet and its hyper-sophistication and passel of unknown vulnerabilities has had the effect of creating a secondary wave of panic about the vulnerability of industrial control and SCADA systems. But the concern about spontaneous utility outages and surreptitiously poisoned food supplies are overblown and largely misplaced, an expert says.


On the same day that it plans to release a patch for a critical flaw in Shockwave, Adobe confirmed on Thursday morning that there is a newly discovered bug in Flash that is being actively exploited already in attacks against Reader. The vulnerability affects Flash on all of the relevant platforms, including Android, as well as Reader on Windows and Mac, and won’t be patched for nearly two weeks.

Samy Kamkar has been making quite a bit of noise lately, beginning with his release of the Evercookie earlier this month and continuing with his talk at the SecTor conference this week on novel methods for stealing users’ cookies without any browser bugs. In this interview, he discusses both of those methods, as well as a new technique he developed that can use Google data and simple attacks to find a user’s physical location within a few feet.

TORONTO–A Google malware researcher gave a rare peek inside the company’s massive anti-malware and anti-phishing efforts at the SecTor conference here, and the data that the company has gathered shows that the attackers who make it their business to infect sites and exploit users are adapting their tactics very quickly and creatively to combat the efforts of Google and others.

TORONTO–If the spate of vulnerabilities and sophisticated attacks against browsers in the last couple of years has done nothing else, it’s certainly shown just how vulnerable users are as they go about their daily business on the Web. In a talk at the SecTor conference, a researcher showed several methods for combining a variety of new and existing attacks that can not just compromise users’ Web accounts but also allow attackers to use that information to extend their attacks in a number of directions.

With bank fraud and attacks against financial institutions and online banking applications having turned into an epidemic, researchers, banks and other concerned parties have been looking for new ways to protect the integrity of financial transactions. A researcher at the University of Cambridge working on the problem has developed a new device that can act as a trusted intermediary to ensure the validity of electronic transactions.
