You’re Invited: A Conversation on Password Security and Targeted Attacks

September 23, 2014 Paul Roberts

A note to Security Ledger readers that I’ll be facilitating a really interesting conversation this afternoon on password (in)security and how weak user authentication can undermine even the best laid security plans. The SANS Webinar, Security for the People: End User Authentication Security on the Internet” kicks off at 3:00 PM Eastern today (12:00 PM Pacific). You can register to join us using this link. My guest is DUO Security researcher Mark Stanislav, a frequent Security Ledger contributor and one of the smartest guys out there when it comes to passwords, authentication and securing the Internet of Things. There’s plenty to talk about: weak authentication schemes are the root cause of any number of prominent breaches – from the recent attacks the Apple iCloud accounts of A-list celebrities, to the breach at retailer Target (reportedly the result of a phishing attack on an HVAC contractor that Target used.) Mark and I […]

The Key to Security in the Internet of Things – IEEE Spectrum

September 19, 2014 Paul Roberts

IEEE Spectrum has an article that provides a nice overview of security and privacy issues on the Internet of Things. The article by Mark Anderson highlights a number of the issues that have cropped up on these pages as well, namely: the rush to market in the consumer IoT space (much of it driven by crowd funding sites like IndieGoGo and Kickstarter) the lack of a strong business case for (consumer) manufacturers to build security into IoT products the tendency of large manufacturers to pursue siloed security standards that thwart efforts to build devices interconnect with other IoT infrastructure (other devices, routers, etc.) So far efforts to coordinate IoT development around a single platform or set of standards have been reduced to predictable turf battles: Google’s Thread versus multi-vendor efforts like TheAllSeen Alliance, The Open Interconnect Consortium, The Industrial Internet Consortium versus Apple HomeKit and HealthKit and others. In the […]

Concept Worm Could Spread Between Networked Attached Storage Systems

September 16, 2014 Paul Roberts

Kelly Jackson Higgins over at Dark Reading has a really interesting story about a researcher who is building a NAS worm. That’s right: some automated malware that will be capable of roaming the Internet finding and compromising consumer network attached storage (NAS) devices. Higgins interviewed Jacob Holcomb, a security analyst at the firm Independent Security Evaluators, has rolled more than two dozen previously unknown and undiscovered (‘zero day’) software vulnerabilities in NAS products into a proof-of-concept, self-replicating worm. According to Higgins, the worm scans for vulnerable services running on NAS systems — mostly web servers — and identifies the type of NAS device and whether it harbors the bugs. If a known, vulnerable platform is discovered, the worm launches the corresponding exploit from its quiver to take control of the device. Compromised devices are then used to scan for other, similar devices. Holcomb has already informed affected vendors – a list that includes […]

Building an Unhackable Autonomous Vehicle – CityLab

September 11, 2014 Paul Roberts

The folks over at The Atlantic have an intriguing take on the subject of “connected vehicles” and autonomous driving. Now this is a vision that we’ve been chasing for more than 50 years (consider all the technicolor “highway of tomorrow” films from the 50s and 60s). And we’re on the cusp of realizing it. Google’s self-driving car is racking up the miles and automated features like hands free cruise control and collision avoidance are making their way into production vehicles. As Alexis Madrigal at The Atlantic’s (cool) CityLab writes, however, there’s one major fly in the ointment when you consider the super efficient, algorithmically driven road of the future: humans. Specifically: Madrigal, in the course of writing an article on how to build an ‘unhackable’ car poses a scenario that I think is very likely: humans who subvert or otherwise game vehicle automation features to suit their own needs. Imagining the orderly procession […]

Report: Deep Links Connect Home Depot, Target Hacks

September 8, 2014 Paul Roberts

Security reporter Brian Krebs has an intriguing post from Sunday that suggests a link between the massive breach at Target Stores in late 2013 and the recently alleged compromise of systems at home improvement giant Home Depot. Home Depot has yet to acknowledge any theft of customer data from its computer systems. However, according to Krebs, an unnamed “source close to the Home Depot investigation” told him that an analysis of compromised computers at Home Depot revealed that some of the store’s registers were infected with a new variant of BlackPOS, a malicious software program designed to run on Windows-based point of sale (or POS) systems and steal card data when cards are swiped. BlackPOS was found on point-of-sale systems at Target last year. In March, the security firm Arbor Networks issued a report that cited BlackPOS as one of a number of point of sale system malware families that cyber criminal groups were using heavily: generating new […]
