Heart Attack? Fixes For More Critical Holes In OpenSSL

Just a month after a critical security hole in OpenSSL dubbed “Heartbleed” captured headlines around the globe, The OpenSSL Foundation has issued an other critical software update fixing six more security holes, two of them critical. The Foundation issued its update on Thursday, saying that current versions of OpenSSL contain vulnerabilities that could be used to carry out “man in the middle” (or MITM) attacks against OpenSSL clients and servers. SSL VPN (virtual private network) products are believed to be especially vulnerable. Users of OpenSSL versions 0.9.8, 1.0.0 and 1.0.1 are all advised to update immediately. According to information released by the OpenSSL Foundation, an attacker using a carefully crafted handshake can force the use of “weak keying material in OpenSSL SSL/TLS clients and servers.” That could lay the groundwork for man-in-the-middle attacks in which an attacker positions herself between a vulnerable client and server, decrypting and modifying traffic as it passes through the attacker’s […]

Podcast: Is Defense-In-Depth The Only Real Heartbleed Fix?

Like everyone else, we wrote extensively in the last month about the serious security vulnerability in OpenSSL dubbed “Heartbleed,” which affected many of the world’s leading web sites and services, including Facebook and Google. The large-type headlines about Heartbleed have passed. But that doesn’t mean that the danger has. As we have noted,  we are entering a phase that might be considered Heartbleed’s ‘long tail.’ Most of the well-trafficked websites that were vulnerable to Heartbleed have gotten around to fixing the vulnerability. But public-facing web servers are only the beginning of the story for OpenSSL. Chasing down the vulnerability’s long tail in third-party applications and on internal web sites and applications is a much larger task. As I’ve noted: open source components make their way into all manner of applications and bespoke products these days, often without any effort to assess the security of the borrowed code. For companies that need to protect critical IT […]

Video: The Internet of Things and Enterprise Risk

The Security Ledger recently hosted our inaugural event: The Security of Things Forum (SECOT). This was a high-energy, day long conference in Cambridge, Massachusetts, that brought together subject experts, executives and thought leaders from disparate areas like high tech, finance and industrial systems to talk about the tsunami of change that is the Internet of Things. One of the big questions hovering over the event: how will IoT technologies and services change the security paradigm that we’ve all be operating under- but especially in enterprises. In fact, IoT and enterprise was the topic of our very first discussion of the day: a panel chaired by Chris Rezendes of INEX Advisors, a leading consultancy focusing on IoT. SECoT Forum 2014 – Democratized Data, IOT and Enterprise Risk from Exhibitor Media Group on Vimeo It’s a really big and messy problem. As panelist Ken Pfeil of Pioneer Investments pointed out: the hack of […]

iPhone and iPad Hijacking: What You Need To Know

The past 24 hours has seen a spate of stories warning about a spate of ‘ransomware’ attacks on iPhones and iPads – especially in the the UK and Australia. According to the reports, compromised devices are locked and owners are instructed to email a ransom (variously: $100, $50, €100) to one “Oleg Pliss” to have their devices unlocked. These attacks aren’t really news. In fact, the Oleg Pliss scam appears to have been circulating for close to six months. However, it’s worthwhile reviewing what we do (and don’t) know about these latest attacks on mobile devices. Accordingly, Security Ledger has put together a short FAQ that tells you what you need to know about the latest mobile scam, and to dispel some of the rumors floating around in the Internet ether. What’s Going On? According to news reports and complaints on Apple Support forums, owners of iPhones and iPads are having their devices locked. […]

Report: Samsung Investing In IoT Security

South Korean electronics giant Samsung Electronics Co. said on Tuesday that it will invest heavily in security for the Internet of Things sector, citing security for IoT as a ‘key future technology’ alongside energy storage and harvesting.   The report on Tuesday, from South Korea’s Yonhap News Service said Samsung, currently the world’s top maker of mobile phones, said Samsung is soliciting proposals on IoT security algorithms and protocols through the end of June. Possible applications include “biometrics, smart structures and advanced traffic networks,” according to Yonhap. The announcement comes by way of Samsung’s Future Technology Fostering Center, a research group that the company established last year to help keep it on the cutting edge in technology. According to published reports, Samsung has pledged 1.5 trillion won ($1.34 billion) over 10 years to fund the Center. Approximately 750 billion won ($670 million) will be allocated to research projects through 2017.
