This Week In Security: Poking Holes In Two Factor Authentication

Podcast: Play in new window | Download ()Subscribe: Apple Podcasts | Android | Email | Google Podcasts | Stitcher | TuneIn | RSS | https://www.securityledger.com/subscribeIt was another busy week in the security world. There was big news on the legal front, as The U.S. Supreme Court took steps to protect the data stored on mobile devices from warrantless searches by police. (That’s good news.) But the week also plenty of concerning stories about the security of data stored on mobile phones, tablets and the like. One of the stories that gained a lot of attention was DUO Security’s report on a flaw in PayPal’s two factor authentication feature that could expose the accounts of  security-conscious PayPal users. As The Security Ledger reported, DUO researcher Zach Lanier discovered a flaw in mobile APIs published by PayPal that would allow anyone with a valid PayPal user name and password to sidestep two-factor […]

Web to Wheels: Tesla Password Insecurity Exposes Cars, Drivers

We’ve interviewed security researcher Nitesh Dhanjani before. In the last year, he’s done some eye-opening investigations into consumer products like the Philips HUE smart lightbulbs. We did a podcast with Nitesh in December where we talked more generally about security and the Internet of Things. Now Dhanjani is in the news again with research on one of the most high-profile connected devices in the world: Tesla’s super-smart electric cars. In a presentation at Black Hat Asia on Friday, he  released findings of some research on the Tesla Model S that suggests the cars have a weakness common to many Web based applications: a weak authentication scheme. (A PDF version of the report is here.) Specifically: Tesla’s sophisticated cars rely on a decidedly unsophisticated security scheme: a six-character PIN. Dhanjani’s research discovered a variety of potentially exploitable holes that would give even an unsophisticated attacker a good chance at breaking into […]

RSA Perspective: Outrage With A Side Of Salsa

Let the record show that one of the most dramatic expressions of discontent over rampant government surveillance of U.S. citizens and private companies during last week’s RSA Conference in San Francisco went down at a taco joint. As the world’s cyber security elite gathered in San Francisco’s Moscone Center for the RSA Security Conference, a group of privacy and online rights activists that go by the name “Vegas 2.0” used donated funds to rent out Chevy’s, a popular Mexican food restaurant located next to the exhibit halls and frequented by conference goers. As reported by ZDNet’s Violet Blue, paying RSA attendees and speakers – identifiable by red badges – were refused entry to Chevy’s and handed flyers explaining the protestors’ grievances against the Conference’s parent company, RSA Security, which is alleged to have colluded with the NSA to weaken encryption standards in its products. Among those reported to have been […]

Windows XP Users Six Times More Likely To Be Infected By Malware

Microsoft came out with a new edition of its Security Intelligence Report today, saying that company data shows that Windows XP machines are much more likely to be infected in encounters with malicious software on the Internet. Windows XP machines were six times more likely to be infected than machines running Windows 8, the latest version of Microsoft’s operating system, the company said. The Security Intelligence Report (or SIR) is a unique window into the malicious activity online, given Microsoft’s massive footprint of more than 1 billion systems running versions of the Windows operating system, and the detailed data it collects from them through its automatic update patching- and malware removal features. This is the 15th such report Microsoft has issued.  The company used the latest report to hammer home a message about the need for Windows XP users to move off that system to a newer version of the […]

Report: Cell Phone Data, Blackberry Mail Swept Up In NSA’s Net

Sensitive data from every major brand of cell phone can be captured and analyzed by the U.S. National Security Agency, (NSA) according to a report in the German magazine Der Spiegel on Saturday.   Citing “top-secret, internal NSA documents viewed by SPIEGEL reporters, the magazine said that NSA security researchers have developed tools to sap contact lists, SMS traffic, notes and location information from popular devices such as Apple’s iPhone, Google’s Android and Blackberry phones, including Blackberry e-mail, a supposedly secure system that is one of the phone’s most trumpeted features. The documents describe a large-scale and well-organized program within the NSA to obtain data from mobile devices, with discrete teams of security analysts working on a specific platform, developing malware that infiltrates the computers the phones “synch” with, and then loads scripts onto the phones that provide access to a range of other features.
