UEFI: Security, BIOS and the Internet of Things

One of the notable trends in recent years has been the drive, among malicious actors, to compromise devices in new- and hard-to-detect ways. An area of interest and exploration is malicious software that can attack a computer’s BIOS – the small bit of code that runs when a computing device is first powered on. BIOS malware is so powerful because it offers adversaries the possibility of getting a foothold on systems prior to an operating system and the security features- and applications that run there. Successful BIOS attacks give attackers almost total control over the system they are installed on. BIOS malware isn’t a new idea. In fact, it has been around since the late 1990s, when the Chernobyl Virus was identified. That virus could wipe a machine’s BIOS, a well as the contents of its hard drive. But BIOS threats have been getting more attention lately. Proof of concept malware appeared as recently […]

IPMI’s Inconvenient Truth: A Conversation With Dan Farmer

The work of brilliant computer security researchers often borders on a kind of madness. After all, it takes dedication and a certain amount of monomania to dig through the mush of disassembled source code or the output of application fuzzers and find the one software vulnerabilities – or chain of vulnerabilities – that might lead to a successful attack. Often, this work puts you at odds with what most of us consider “the real world.” Notably: the well-respected researcher Dragos Ruiu had many in the security community wondering about his sanity after he sounded the alarm about a super stealthy piece of BIOS malware he dubbed “BadBIOS” that seemed to be everywhere and nowhere, all at once. Dan Farmer finds himself in a similar position as he continues to sound alarms about the security threat posed by insecure implementations of the Intelligent Platform Management Interface (IPMI)– a ubiquitous protocol used to do remote […]

IPMI Insecurity Affects 200k Systems

It has been almost a year since security researcher Dan Farmer first warned of the danger posed by Intelligent Platform Management Interface (IPMI) – a ubiquitous protocol used to do remote management of servers. According to a new report, however, that warning went unheeded. Writing last week (PDF), Farmer said that a world-wide scan for systems using the Intelligent Platform Management Interface (IPMI) protocol identified over 230,000 Baseboard Management Controllers (BMCs) exposed to the Internet. As many as 90% of the exposed systems could be compromised by exploiting what Farmer characterized as “basic configuration and protocol weaknesses.” Even more worrying, the 230,000 systems that are Internet accessible are probably just a fraction of all the vulnerable systems that might be attacked, with many deployed on (hackable) corporate and private networks. Farmer is reiterating calls for public and private sector organizations to wake up to the dangers posed by IPMI. Hackers who are able to compromise Baseboard Management […]

Big GOV Shift To Secure Cloud?

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 […]

Report: Hell is Unpatched Systems

One of the ‘subplots’ of the Internet of Things revolution concerns embedded devices. Specifically: the tendency of embedded devices to be either loosely managed or – in some cases – unmanageable.   The future holds the promise of more, not fewer of these. That’s the gist of a piece I wrote for InfoWorld, and that you can read here. In short: we’re already seeing the beginning of a shift on the threat landscape. While attacks against traditional endpoints (like Windows desktops, laptops and servers) are still the norm, there are more stories each day about cyber criminal groups and malicious actors who are compromising non-standard endpoints like home wifi routers.  In March, for example, the security consultancy Team Cymru identified a botnet consisting of some 300,000 compromised home routers and other in-home devices. The virus called “TheMoon” was also identified spreading between vulnerable home routers and other embedded devices. The […]
