New Shodan Tool Warns Organizations of Their Internet-Exposed Devices

Shodan Monitor is free to members of the popular Internet search engine.

Famed Internet search engine Shodan this week rolled out a service that helps solve the underlying problem its tool exposes: The new Shodan Monitor alerts organizations about their devices left exposed on the public Internet.

Security researchers long have employed the Shodan search tool to identify computers, databases, industrial control systems and devices, and consumer Internet of Things (IoT) products sitting wide open to attackers via open Internet ports or other misconfigurations. Most recently, a researcher discovered a MongoDB data instance with 150 gigabytes of data, including some 763 million email addresses, sitting on the public Net and in plain text. 

"Every other week there's an exposed database leaking information or a consumer device that was misconfigured and is now exposing private data. The number of industrial control systems directly connected to the Internet without any authentication has been increasing at a rate of about 10% every year," says John Matherly, creator and founder of Shodan. The wave of consumer IoT devices also is increasing, he says.

"Knowing what you have exposed to the Internet is required before any further security work can be done," he explains. "It shouldn't be rocket science to know what you have exposed to the Internet."

Shodan Monitor represents a new brand of tool for Shodan, an online continuous monitoring service. Renowned security expert HD Moore – a pioneer in rooting out exposed and vulnerable devices and systems on the Internet, such as embedded devices, home routers, servers, corporate videoconferencing systems, and Web servers – says many "outside-in" scanning firms such as Shodan are expanding into continuous monitoring. They include Assetnote, BinaryEdge, Bit Discovery, Expanse.co, Hardenize, RiskRecon, and SecurityScorecard.

"I think monitoring is the way to make this technology most effective; bulk data and searching is nice, but it is much more useful when someone else does the difficult attribution work for you and tells you what changed," says Moore, vice president of research and development for consultancy Atredis Partners. "It has been a fun few years watching the 'scan the Internet' firms turn their platforms into actual businesses."

Shodan's Matherly says Monitor was built to be simple and inexpensive, and a tool for organizations with less technical know-how and resources. "From a strategic perspective, this is our first foray into creating services that don't require advanced technical knowledge. In the past, much of our focus was on the Shodan platform, which has been capable of doing this for a long time, but it required usage of our API, which means there was a technical barrier to entry," he says. "After a decade of building out the platform, it's time to make it more accessible to nontechnical users."

Matherly says setting up Shodan Monitor – which is free to all paying Shodan members – takes less than a minute, and Shodan sends an email when it finds an exposed device. It monitors up to 16 IPs for Shodan members (who pay $49 to join) and 300,000 IPs for Shodan Corporate API members. He says many of the existing services and products that offer this type of monitoring are pricey and overly complex, with an overload of dashboard data and confusing alerts.

"We're hoping that this will put a dent in the number of exposed devices and prevent recurring issues like we see with MongoDB and industrial control systems," he says.

Stephen Cobb, senior security researcher at ESET, notes that it's become more difficult for organizations to get a handle on their networks. "Today's rapidly expanding universe of sensors, cloud storage, remote access, and IoT devices has created levels of complexity that are impossible to secure without constant monitoring, both within and without," he says. He sees Shodan Monitor as a tool for organizations that don't have the technical expertise or resources.

"Since its inception, Shodan has played a valuable role in monitoring efforts while at the same time revealing the need for such monitoring," Cobb says.

Re: Will this impact white hat researchers?
I think the good news is that it will help more organizations get on top of their devices and systems that are exposed on the public Net.

Monitor
Shodan Monitor as a tool for organizations that don't have the technical expertise or resources. It is important to monitor obviously. Tools provide help to speed up and make unmanageable manageable.

Shodan
Shodan sends an email when it finds an exposed device. Sound like another device we need to share information with. That is the main reason of the leaks.

Encryptions as a norm
Every other week there's an exposed database leaking information or a consumer device that was misconfigured and is now exposing private data. I think we should think encryptions at rest as a norm at this point.

Re: Will this impact white hat researchers?
if this will reduce white hat researchers' ability to discover and disclose exposed devices and data bases. Not really I would say. Less a lot their ability more about vulnerabilities.

Emails
a researcher discovered a MongoDB data instance with 150 gigabytes of data, including some 763 million email addresses, sitting on the public Net and in plain text. Obviously this is more common than what we think. At the same time email is not considered private anymore. Our emails are all over the places today.

Intriguing news, thanks for this Kelly. I can't help but wonder if this will reduce white hat researchers' ability to discover and disclose exposed devices and data bases.
