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 […]
Hacks & Hackers
Perverse Security Incentives Abound In Mobile App Space
Security problems abound in the mobile device space – and many of them have been well documented here and elsewhere. While mobile operating systems like Android and iOS are generally more secure than their desktop predecessors, mobile applications have become a major source of woe for mobile device owners and platform vendors. To date, many of the mobile malware outbreaks have come by way of loosely monitored mobile application stores (mostly in Eastern Europe and Russia). More recently, malicious mobile ad networks have also become a way to pull powerful mobile devices into botnets and other malicious online schemes. But my guests on the latest Security Ledger podcast point out that mobile application threats are poised to affect much more than just mobile phone owners. Jon Oberheide, the CTO of DUO Security and Zach Lanier, a researcher at DUO, note that mobile OS platforms like Android are making the leap […]
SOHOwned: 300K Home Routers Hacked
A string of reports in recent weeks has focused a spotlight on rising attacks against an often-overlooked piece of equipment that can be found in almost every home and business: the wireless router. Just this week, the security firm Team Cymru published a report (PDF) describing what it claims is a widespread compromise of small office and home office (SOHO) wireless routers that was linked to cyber criminal campaigns targeting online banking customers. Cymru claims to have identified over 300,000 SOHO devices (mostly in Asia and Europe) that were compromised. According to the report, the compromises first came to light in January, after Team Cymru analysts noticed a pattern of SOHO routers with overwritten DNS settings in central Europe. The affected devices are from a range of manufacturers, including well-known brands like D-Link, Micronet, Tenda and TP-Link. The devices were vulnerable to a number of attacks, including authentication bypass and cross-site […]
Update – Virtual Vandalism: Firm Warns Of Connected Home Security Holes
[This story was updated to include response from Belkin describing its response to the vulnerabilities identified by IOActive, including firmware updates. – PFR Feb 19, 2014] A researcher with the respected security firm IOActive says that he has found a number of serious security holes in home automation products from the firm Belkin that could allow remote attackers to use Belkin’s WeMo devices to virtually vandalize connected homes or as a stepping stone to other computers connected on a home network. In a statement released on Tuesday, IOActive researcher Mike Davis said that his research into Belkin’s WeMo technology found the “devices expose users to several potentially costly threats, from home fires with possible tragic consequences down to the simple waste of electricity.” IOActive provided information on Davis’s research to the US Computer Emergency Readiness Team (CERT), which issued an advisory on the WeMo issues on Tuesday. Belkin did not […]
Veterans Targeted In Attack Using IE 10 Zero Day
Visitors to the web site of the Veterans of Foreign Wars (VFW) are being targeted in an attack that exploits a previously unknown hole in Microsoft’s Internet Explorer 10 web browser, according to warnings Thursday by security firms. Some visitors to the web site of the Veterans of Foreign Wars (VFW), vfw[dot]org, were the victim of a ‘watering hole’ attack that takes advantage of a previously unknown ‘use-after-free’ vulnerability in Microsoft’s Internet Explorer 10 web browser. The VFW site was hacked and then altered to redirect users, silently, to a malicious website programmed to exploit vulnerable versions of IE 10 on systems running 32 bit versions of the Windows operating system. The VFW did not immediately respond to e-mail and phone requests for comment. According to a write-up by the security firm FireEye, the vulnerability allows the attacker to “modify one byte of memory at an arbitrary address” stored […]
