Whack-A-Bash: New Vulnerabilities add to Patch Confusion

The good news about the rapid, industry response to the revelations about exploitable security holes in GNU Bash (Bourne Again Shell) (aka “Shellshock”) is that Linux users had a fix in hand almost as soon as they became aware of the problem those patches addressed. The bad news about the quick fixes for the two issues, CVE-2014-6271 and CVE-2014-7169, from the likes of Red Hat, Ubuntu, Debian and others is that – in being early- they fail to fix the problems we don’t yet know about. And that’s what we’re seeing in the wake of last week’s storm of patches: a steady drip-drip of disclosures that suggest that Bash may contain other problems worthy of new fixes. Within hours of the disclosure of the first holes, there were problems discovered by Red Hat Product Security researcher Todd Sabin, who found additional “off by one” errors in Bash that were assigned CVE-2014-7186 and CVE-2014-7187 and […]

Internet of Things and Enterprise Risk Panel

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 […]

Heartbleed: Technology Monoculture’s Second Act

Say ‘technology monoculture’ and most people (who don’t look at you cross-eyed or say ‘God bless you!’) will say “Microsoft” or “Windows” or “Microsoft Windows.” That makes sense. Windows still runs on more than 90% of all desktop systems, long after Redmond’s star is rumored to have dimmed next to that of Apple. Microsoft is the poster child for the dangers and benefits of a monoculture. Hardware makers and application developers have a single platform to write to – consumers have confidence that the software and hardware they buy will “just work” so long as they’re running some version of Windows. The downside, of course, is that the Windows monoculture has also been a boon to bad guys, who can tailor exploits to one operating system or associated application (Office, Internet Explorer) and be confident that 9 of 10 systems their malicious software encounters will at least be running some version of the […]

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 […]

Podcast: Security Challenges Ahead For Blackberry

With another busy week behind us in the security world, we sat down with Zach Lanier, a senior security researcher for mobile authentication specialist Duo Security. Zach is a recognized authority on the security of mobile devices, and was able to talk about some ongoing research he’s doing on Blackberry’s BB10 operating system. Zach told us that Blackberry 10, the latest version of Blackberry’s mobile operating system, is a big improvement over previous versions, including the TabletOS that Blackberry (formerly Research in Motion) used for its PlayBook – the company’s first foray into the tablet space.  But Lanier and fixed many of the information leaks that he and others found in TabletOS and reported to the company. “But there are still lots of questions we’re looking to answer,” Lanier said.   Among other things, Lanier is examining whether Blackberry 10’s support for so many different runtimes might pose security problems for […]
