Does your team use Slack to collaborate? If so, we've released a thing that you might like ;-) A few days ago, we announced a new feature of our web interface that allows you to chat directly with Senrio support engineers.

But today, we are announcing that in addition to existing integrations with Splunk, RSA, SEIMs, all major firewalls, and familiar dashboards, now you can ask Senrio Insight questions about your network directly from Slack! Any question. Don't know what an asset is, and only have a piece of the story? Ask Senrio with the piece you have, and get back the whole story. It's like the asset "search engine" for your network.

Check out the video below to see what we mean.

January 30th – Portland, OR – Senrio, Inc., provider of the leading IoT visibility and security solution has announced an interoperability with the RSA NetWitness® Suite to enable users to detect and respond to threats to IoT devices.

The RSA NetWitness and Senrio Insight interoperability helps ensure that critical data about the status and operation of both IoT devices as well as traditional endpoints and assets is sent to the RSA NetWitness Suite from the Senrio platform, which uses predictive analytics and expert input to determine normal behavior, and trigger alerts when abnormal behavior is detected.

Senrio Founder Stephen Ridley said, “IoT is a blind spot in most enterprises. Most aren’t sure what devices they have, much less if they’re compromised or otherwise pose a risk to people or operations. By integrating Senrio Insight data in the RSA NetWitness Suite, organizations will gain unprecedented visibility into the IoT devices in their enterprise and more effectively deal with safety or security concerns.”

This interoperability allows organizations to quickly identify all connected devices in their enterprise, and build profiles of device behavior. This knowledge enables IT administration and security teams the ability to build trust with devices by understanding typical device behavior, and rapidly respond when atypical patterns of behaviors are detected by Senrio’s self-learning technology.

Senrio Insight was designed specifically for the challenges of an IoT-rich enterprise. Designed to be lightweight, it puts no burden on your network, does not impact data privacy, and is up and running in minutes.
 
About Senrio

Senrio is an IoT security company that was founded on the belief that, with the right mindset and proper tools, we can bridge the gap between legacy security approaches and the new reality of the IoT. Our mission is to provide the visibility and actionable insights essential to ensuring the security and safety of all connected devices. We envision a world where our trust in the IoT matches the benefits it brings to our lives. Senrio is a trusted partner of global technology companies and government agencies.

Summary
Given the increasingly vital role IoT plays in modern life, we strive to improve the state of IoT security and share the knowledge we gain through our research with IoT manufacturers and users.

Our latest discovery was found in an Axis Communications security camera — the M3004 model. Axis Communications is one of the largest manufacturers of security web cameras globally. In fact, while passing through LAX last week, we saw one of the vulnerable models in use at the airport.

After about a day of analysis, we discovered a stack buffer overflow vulnerability (CVE-2017-9765), which we’re calling Devil’s Ivy*. Devil’s Ivy results in remote code execution, and was found in an open source third-party code library, from gSOAP (more on that later). When exploited, it allows an attacker to remotely access a video feed or deny the owner access to the feed. Since these cameras are meant to secure something, like a bank lobby, this could lead to collection of sensitive information or prevent a crime from being observed or recorded.

Axis informed us that Devil’s Ivy is present in 249 distinct camera models, the exception being three of their older cameras. Once we verified Axis’s fix prevented our exploit from working, Axis quickly began releasing patched firmware and prompting partners and customers to upgrade.

THE IMPACT GOES FAR BEYOND AXIS

The impact of Devil’s Ivy goes far beyond Axis. It lies deep in the communication layer, in an open source third-party toolkit called gSOAP  (Simple Object Access Protocol). gSOAP is a widely used web services toolkit, and developers around the world use gSOAP as part of a software stack to enable devices of all kinds to talk to the internet. Software or device manufacturers who rely on gSOAP to support their services are affected by Devil’s Ivy, though the extent to which such devices may be exploited cannot be determined at this time. Based on our research, servers are more likely to be exploited. But clients can be vulnerable as well, if they receive a SOAP message from a malicious server.

We recently discovered two vulnerabilities in TP-Link’s WR841N V8 router that we exploited to obtain custom code execution on the router. After working closely with the vendor to patch the router’s firmware, we are disclosing the details of our work. 

Our team conducts research into networked embedded devices in order to improve our product and spread security knowledge among the embedded device manufacturing and security communities. The WR841N is the  same router model we use to teach students about hardware hacking in our classes, and the focus of our JTAG Explained blog post. During the process of our research into this router, we found a logic flaw in a configuration service which allowed us to circumvent its access controls and reset the router’s credentials (CVE-2017-9466). We then used our increased access to gain code execution by exploiting a stack overflow vulnerability available through the configuration service. 
​
In this proximity-based attack, we used a smartphone’s hotspot capability to reset the router’s credentials by taking advantage of a protocol that had been removed from the firmware for newer hardware models. Unfortunately, although older models may no longer be supported, they often remain in critical positions. Fortunately, TP-Link agreed to remove the configuration service from this model once we brought the issue to their attention.

We are sharing the details, step by step, in case our work sparks any ideas or discussion regarding proximity-based attacks, unsupported versions, logic flaws in encryption, or vulnerable configuration services.

​Investing in a company, whether that investment is time, money, or reputation, starts with people. You invest in people that inspire, and Stephen Ridley, Founder of Senrio, is one of those people. He blends incredible enthusiasm with world-class expertise. I saw this first hand when we worked together on bleeding-edge projects for the Intelligence Community 10 years ago. But the team is more than Stephen.  The Senrio family he is assembling (and has already assembled), has that ideal mix of hunger and experience. That passion and capacity continues to scale as the employee count grows, and success for Senrio has not hurt their humility. This group will continue to attract like-minded individuals.

Jamison's "big picture" approach to understanding Infosec solutions comes from years spent learning (and presenting) the details beyond the technicalities of a hack.  Instead he delves into the workings of the criminal industry; how and why malware is written, how criminals monetize attacks, and how understanding attacker motivations helps protect networks against malicious forces. Armed with this knowledge, Jamison has built teams to help deploy custom solutions to meet customer need. Jamison is a contributor to ITSP magazine and has blogged on  various cyber security topics.  ​

In our last post we talked about a vulnerability discovered in the D-Link DCS-930L Cloud Camera. Since then the Senrio Research Team has been working closely with the D-Link Security Incident Report Team. Below we disclose technical details of our efforts.
