Heartbleed For Poets And Other Must-Reads

April 10, 2014 Paul Roberts

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 […]

Perverse Security Incentives Abound In Mobile App Space

March 24, 2014 Paul Roberts

Security problems abound in the mobile device space – and many of them have been well documented here and elsewhere. While mobile operating systems like Android and iOS are generally more secure than their desktop predecessors, mobile applications have become a major source of woe for mobile device owners and platform vendors. To date, many of the mobile malware outbreaks have come by way of loosely monitored mobile application stores (mostly in Eastern Europe and Russia). More recently, malicious mobile ad networks have also become a way to pull powerful mobile devices into botnets and other malicious online schemes. But my guests on the latest Security Ledger podcast point out that mobile application threats are poised to affect much more than just mobile phone owners. Jon Oberheide, the CTO of DUO Security and Zach Lanier, a researcher at DUO, note that mobile OS platforms like Android are making the leap […]

Veterans Targeted In Attack Using IE 10 Zero Day

February 13, 2014 Paul Roberts

Visitors to the web site of the Veterans of Foreign Wars (VFW) are being targeted in an attack that exploits a previously unknown hole in Microsoft’s Internet Explorer 10 web browser, according to warnings Thursday by security firms. Some visitors to the web site of the Veterans of Foreign Wars (VFW), vfw[dot]org, were the victim of a ‘watering hole’ attack that takes advantage of a previously unknown ‘use-after-free’ vulnerability in Microsoft’s Internet Explorer 10 web browser. The VFW site was hacked and then altered to redirect users, silently, to a malicious website programmed to exploit vulnerable versions of IE 10 on systems running 32 bit versions of the Windows operating system. The VFW did not immediately respond to e-mail and phone requests for comment. According to a write-up by the security firm FireEye, the vulnerability allows the attacker to “modify one byte of memory at an arbitrary address” stored […]

When The Internet of Things Attacks! Parsing The IoT Botnet Story

January 21, 2014 Paul Roberts

I spent most of last week at a conference in Florida going deep on the security of critical infrastructure – you know: the software that runs power plants and manufacturing lines. (More to come on that!) While there, the security firm Proofpoint released a statement saying that it had evidence that a spam botnet was using “Internet of Things” devices. The company said on January 16 that a spam campaign totaling 750,000 malicious emails originated with a botnet made up of “more than 100,000 everyday consumer gadgets” including home networking routers, multi media centers, televisions and at least one refrigerator.” Proofpoint claims it is the “first time the industry has reported actual proof of such a cyber attack involving common appliances.” [Read: “Missing in action at Black Hat: the PC.”] Heady stuff – but is it true? It’s hard to know for sure. As with all these reports, it’s important […]

Experts: Despite Warnings, Slow Progress Securing Industrial Systems

January 16, 2014 Paul Roberts

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 […]
