Is Analog The Answer To Cyber Terrorism?

March 17, 2014 Paul Roberts

Ralph Langner is one of the foremost experts on the security of critical infrastructure that we have. So, generally, when Ralph says something – whether its about Stuxnet, or cyberwar or the security of nuclear power plants – folks listen. And these days, Ralph is wondering, out loud, whether our reliance on digital systems to manage critical infrastructure has gone too far. The answer, he suggests, may be to go “back to the future,” as it were: reintroducing analog systems into the control process chain as a backstop for cyber attacks. Case in point: the Department of Homeland Security’s ICS-CERT warned on Friday that firmware for Siemens SIMATIC S7-1500 CPUs (Central Processing Units) contain nine vulnerabilities that could enable attacks such as cross site request forgery, cross site scripting and URL redirection. (Siemens has issued a firmware update that patches the holes.) Langner is among the world’s foremost experts on […]

Is Refrigerator Spam Really In Our Future?

March 12, 2014 Paul Roberts

I came across an interesting post over on Wearable World News today titled “The Danger of Smart Spam In the Internet of Things.” The article, by Jessica Groopman, ran yesterday and provides a kind of conceptual overview of the security and IoT space. I think Goodman gets it mostly right: she talks about the proliferation of device types and platforms that will (or already does) characterize the Internet of Things. With hundreds of billions (compared with hundreds of millions) of Internet connected endpoints, cyber criminals, hacktivists and other bad actors have an even greater ability to create armies of compromised endpoints and harness their collective power in attacks. Goodman also gets it right when she notes that many “smart” devices run commodity operating systems like Linux and don’t require lots of special effort to reverse engineer. Finally, IoT devices frequently are low power and embedded systems that lack the processing […]

SOHOwned: 300K Home Routers Hacked

March 4, 2014 Paul Roberts

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

February 18, 2014 Paul Roberts

[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 […]

Vulnerability Undermines WordPress Two-Factor Plugins

February 14, 2014 Paul Roberts

The firm Duo Security* said that it has discovered a vulnerability that affects a range of two-factor authentication plugins for the WordPress content management platform. The vulnerability could allow a malicious insider to use credentials for one WordPress site to log into a different site that is part of a ‘multi-site’ WordPress deployment without needing to pass a multi-factor authentication test. In a blog post on Thursday, DUO co-founder and CTO Jon Oberheide said that the vulnerability was discovered as part of an internal review of DUO’s two factor WordPress plugin, but that researchers realized it affects at least two other multi-factor plugins. DUO issued a warning to users of its plugin. The company also reached out to WordPress and to the publishers of other multi factor authentication plugins to address the issue, Oberheide wrote. DUO makes multi-factor authentication technology that allows users to log-in using a combination of username, […]
