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 […]

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 […]
Uncle Sam Makes Mobile, Medical Device Security a Priority in 2014
The U.S. Department of Health and Human Services (HHS) says that it will make the security of mobile devices containing personal health information and networked medical devices areas of intense scrutiny in 2014. The security of a wide range of devices, from laptops and USB ‘jump drives’ to networked medical devices like dialysis machines and medication dispensing systems will be under review, according to a 2014 Work Plan issued by HHS’s Office of the Inspector General (OIG). (PDF) Among other projects, the OIG will review hospitals’ plans to protect the loss of protected health information (PHI), as well as similar plans put in place by Medicare and Medicaid contractors in the next year. OIG will also scrutinize security controls at hospitals that protect networked medical devices. OIG wants to determine if the controls in place are adequate to secure electronic protected health information stored on medical devices. Links between networked […]
Target Breach Spells End for Magnetic Stripe Cards in 2015
After years spent fighting pushes for more secure standards, the payment card industry and retailers are moving quickly to abandon magnetic stripe cards and embrace so-called ‘chip and pin’ technology. Credit card firms MasterCard and Visa plan to have most customers on the more secure chip and pin cards by October, 2015, according to a report in the Wall Street Journal. The move comes in the wake of a massive heist of account information for tens of millions of credit card holders from the systems of U.S. retailers including Target, Neiman Marcus and Michaels Stores. In an interview with MasterCard’s Carolyn Balfany, the Journal notes that company has set October, 2015 as the date for a “liability shift” – a change in policy that will hold the party in a fraudulent transaction liable for losses due to that transaction. The goal, said Balfany, is to try to encourage merchants and […]
