Biggest Threat to Critical Infrastructure? Lack of Imagination

November 18, 2014 Paul Roberts

The threats to critical infrastructure in the U.S. and elsewhere are so plentiful that even trying to enumerate them is futile (and not a bit depressing). But – if we were to rank them in order of importance – what would be at the top of that list? Clearly, as this blog has noted, software security is a major concern. Recently, the Industrial Control System CERT (ICS-CERT) warned about a sophisticated malware campaign targeting users of HMI (human-machine-interface) technology from leading vendors. In at least some cases, the systems targeted were exposed directly to the Internet, making compromise simple. In other cases, industrial control system software is deployed with default administrator credentials, or easy to guess passwords. In other words: while some attackers are persistent and clever, many critical infrastructure owners make their job pretty easy. So, perhaps, its not software insecurity that belongs at the top of the list, […]

Malware Campaign Against Industrial Systems Almost 3 Years Old

October 30, 2014 Paul Roberts

The U.S. Government’s Industrial Control System CERT (ICS-CERT) said on Thursday that a campaign targeting industrial control system (ICS) software began in January, 2012 and targeted industrial systems that were directly connected to the public Internet. ICS-CERT said in an alert published on Wednesday that “HMI” (or Human-Machine Interfaces) products from vendors including GE, Advantech/Broadwin and Siemens may have been infected with variants of the BlackEnergy malware since January, 2012. Infected firms were running versions of the GE’s Cimplicity, Advantech/Broadwin’s WebAccess or Siemens’ WinCC with what ICS-CERT called a “direct Internet connection.” In some cases, as with the GE Cimplicity attacks, hackers exploited a known vulnerability in the Cimplicity software to gain access. In others (as with WebAccess and WinCC) the method by which the software was compromised isn’t known, ICS-CERT said. CERT said it hasn’t documented any cases of control processes being modified by the malware. However, BlackEnergy is typically used […]

Dan Geer’s Other Keynote: Embedded Devices Need A Time To Die

August 4, 2014 Paul Roberts

With the Black Hat Conference well under way and DEFCON starting later this week, the security world’s attention will turn to Las Vegas, where some of the cyber security industry’s top researchers and thinkers will be holding court. One of the most anticipated talks is the Black Hat Briefings opening keynote. This year, the honor goes to none other than Dr. Dan Geer, the CISO of In-Q-Tel, the investment arm of the U.S. intelligence sector. Geer’s talk on Wednesday, August 6, 2014 is entitled “Cybersecurity as Realpolitik.” In anticipation of Dr. Geer’s Black Hat, we’re releasing another recent talk he gave: this one a keynote speech at our May, 2014 Security of Things Forum in Cambridge, MA. In this talk, Dan focused on the security of embedded devices and the fast-emerging Internet of Things. (A full transcript of the talk is available here.) “The embedded systems space, already bigger than what is normally thought of as […]

DHS Warns Energy Firms Of Malware Used In Targeted Attacks

July 1, 2014 Paul Roberts

The Department of Homeland Security warned firms in the energy sector about new, targeted malware infecting industrial control systems and stealing data. DHS’s ICS CERT, the Industrial Control Systems Computer Emergency Response Team, said it is analyzing malware associated with an ICS-focused malware campaign. The malicious software, dubbed “Havex” that was being spread by way of phishing emails and so-called “watering hole” attacks that involved compromises of ICS vendor web sites. DHS was alerted to the attacks by researchers at the security firms Symantec (which dubbed the malware campaign “Dragonfly”) and F-Secure (“Havex”) -a remote access trojan (or RAT) that also acts as an installer (or “downloader”) – fetching other malicious applications to perform specific tasks on compromised networks. One of those additional payloads is a Trojan Horse program dubbed Karagany (by Symantec) that has been liked to prior attacks on energy firms. According to Symantec, the malware targeted energy grid operators, major electricity generation firms, […]

Big GOV Shift To Secure Cloud?

June 2, 2014 Paul Roberts

For those of us covering the cyber security beat, there haven’t been many feel-good stories coming out of the federal government in – well – forever. Even before the advent of nation state sponsored hacking, the news was mostly of the federal government’s bloated and unwieldy IT infrastructure, byzantine procurement systems and the difficulty of attracting top talent away from private sector employers who could offer more pay, more autonomy and a better working environment. Then came the gut wrenching display of offensive prowess by the U.S.’s main enemies – nations like China, Russia and Iran. Those stories started, in earnest, with news about operations like Titan Rain (in 2003) and continue to the present day. The problem has gotten so bad that the military’s preferred euphemism for Chinese hackers – “advanced persistent threat,” or “APT” has become part of the nomenclature of the IT security world far beyond […]
