Update: Serial Server Flaws Expose Critical Infrastructure

A survey conducted by the firm Rapid 7 has found evidence that widespread vulnerabilities and insecure configuration of ubiquitous networking components known as serial port (or “terminal”) servers, may expose a wide range of companies and critical assets – including point of sale terminals, ATMs and industrial control systems – to remote cyber attacks.(*) The vulnerable devices connected hardware like retail point-of-sale systems at a national chain of dry cleaners, providing direct access to employee terminals from which customer payment information could be accessed. Other exposed systems were used to monitor the location of cargo containers, train cargo as well as HVAC and industrial control systems, Rapid7 said. In the Rapid7 survey, over 114,000 unique IPs were identified in a scan using the Simple Network Management Protocol (SNMP), the vast majority manufactured by one company: Digi International. If left unaddressed, the vulnerable devices give remote attackers direct, administrative access to hardware devices […]

UPDATE: Vulnerability In EAS To Blame For Fake Zombie Apocalypse Warning?

Editor’s Note: Updated to include information on the brand of EAS device that was compromised. – PFR 2/14/2013 OK – the good news is that the dead aren’t rising from their graves and the Zombie Apocalypse hasn’t begun (yet…). The bad news: a phony EAS (Emergency Alerting System) warning about just such a cataclysm earlier this week may have been the result of a hack of what one security researcher says are known vulnerabilities in the hardware and software that is used to distribute emergency broadcasts to the public in the U.S. The warning from Mike Davis, a Principal Research Scientist at the firm IOActive, comes just days after unknown hackers compromised EAS systems at television stations in the U.S. and broadcast a bogus emergency alert claiming that the “dead were rising from their graves” and attacking people. Published reports say that at least four television stations were the victims […]

For Industrial, Medical Systems: Bugs Run In The Family

On the surface, the kinds of industrial control systems that run a power plant or factory floor are very different from, say, a drug infusion pump sitting bedside in a hospital intensive care unit. But two security researchers say that many of these systems have two important things in common: they’re manufactured by the same company, and contain many of the same critical software security problems. In a presentation at gathering of industrial control security experts in Florida, researchers Billy Rios and Terry McCorkle said an informal audit of medical devices from major manufacturers, including Philips showed that medical devices have many of the same kinds of software security holes found in industrial control system (ICS) software from the same firms. The research suggests that lax coding practices may be institutionalized within the firms, amplifying their effects. Rios (@xssniper), a security researcher at Google, and McCorkle (@0psys), the CTO of SpearPoint […]

University Course Will Teach Medical Device Security

The University of Michigan will be among the first to offer graduate students the opportunity to study the security of advanced medical devices. The course, EECS 598-008 “Medical Device Security” will teach graduate students in UMich’s Electrical Engineering and Computer Science program “the engineering concepts and skills for creating more trustworthy software-based medical devices ranging from pacemakers to radiation planning software to mobile medical apps.” It comes amid heightened scrutiny of the security of medical device hardware and software, as more devices connected to IP-based hospital networks and add wireless monitoring and management functionality. The new course comes amid rapid change in the market for sophisticated medical devices like insulin pumps, respirators and monitoring stations, which increasingly run on versions of the same operating systems that power desktops and servers. In 2011, the US Food and Drug Administration (FDA) reported that software failures were the root cause of a quarter […]

FBI Issued Alert over July Attack on HVAC System

The FBI issued an alert to businesses in July after unknown attackers breached a computer used to control the heating, ventilation and air conditioning (HVAC) system of a New Jersey company, accessing a graphical user interface for the system, including a floor play layout of the company’s office. The attacks came after an Anonymous affiliated hacker, using the handle @ntisec, published links to vulnerable ICS systems running software from the firm Tridium online. The links included the address of an administrative system that controlled the HVAC system used by US Business 1, a New Jersey company that installs air conditioning systems for other companies, according to a copy of the July, 2012 Situational Information Report (PDF), issued by the Newark Division of the FBI. The alert concerning the February and March, 2012 attack was released by the web site Public Intelligence on Saturday. The FBI did not respond to a request for comment from Security […]
