Heartbleed For Poets

Heartbleed For Poets And Other Must-Reads

It’s H-Day + 2 – two full days since we learned that one of the pillars of online security, OpenSSL, has contained a gaping security hole for the past two years that rendered its protections illusory. As I wrote over on Veracode’s blog today: this one hurts. It exposes private encryption keys, allowing encrypted SSL sessions to be revealed. Trend Micro data suggests around 5% of one million Internet top-level domains are vulnerable.  IOActive notes that Heartbleed also appears to leave data such as user sessions subject to hijacking, exposes encrypted search queries and leaves passwords used to access online services subject to snooping, provided the service hasn’t updated their OpenSSL instance to the latest version. In fact, its safe to bet that the ramifications of Heartbleed will continue to be felt for months – even years to come. In the meantime, there is a lot of interesting coverage and […]

Is Analog The Answer To Cyber Terrorism?

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 […]

Experts: Despite Warnings, Slow Progress Securing Industrial Systems

Despite increased media attention to the security of industrial control systems and critical infrastructure, progress in securing those devices has been slow, experts say. Despite progress in some areas, critical infrastructure – including energy and transportation networks- remains vulnerable to attacks leveled at known security holes for months or years because of a lack of vendor response or customers who lack the incentive or know-how to patch vulnerable systems. That according to some of the world’s top experts in cyber security and industrial systems, who are gathering this week at an industry conference in Miami. The S4 Conference, sponsored by the firm DigitalBond, is one of the premiere conferences for cyber security as it pertains to industrial control systems and often coincides with disclosures from industrial system vendors about serious security holes in their products. The security of industrial control systems has been a top concern of IT security experts and government […]

Siemens Patches Holes In Industrial Control Switch

A security researcher discovered two, serious security holes in a switch by Siemens that could allow an attacker to hijack industrial control system hardware that is heavily used by energy and transportation firms, among others. IOActive, a security consulting firm in Seattle, Washington, said on Thursday that Eireann Leverett, a senior security consultant, discovered two vulnerabilities in Siemens’ SCALANCE X-200 Switches. The vulnerabilities were in a web server component that provided administrators with access to features needed to configure the switches. If exploited, they would have allowed an attacker who had access to the same network as the SCALANCE switch to perform administrative actions on the devices, including updating the switch firmware and hijack active web sessions – all without needing to first log in to the device. SCALANCE is a family of Ethernet switches that connect to industrial control system (ICS) devices including programmable logic controllers (PLCs) and Human […]

Week In Security: NSA Spies on Yahoo & Google, Adobe Hack and Healthcare.gov

There’s nothing like a Sunday morning for looking back over the week’s events and trying to make sense of at all – or at least what sense there is to be had. This Sunday was no different – especially after a week that saw continued revelations stemming from Edward Snowden’s leak of classified intelligence on NSA spying, the massive hack of software maker Adobe. Then there was the botched rollout of the federal Healthcare.gov marketplace – which morphed into an even bigger, uglier problem as the week progressed. To help me sort it all out, I called on Nick Selby, the CEO of StreetCred Software and an authority on cyber security, law enforcement, government procurement, Russia, Germany, aviation, travel journalism and all manner of other topics. I love talking to Nick because his wealth of life and professional experience make him predictably unpredictable when it comes to interpreting current events. […]
