The Internet of Things has come under attack by pranksters in recent days. The events could signal tumultuous things to come as more and more everyday objects connect to the Internet.
The U.S. Department of Homeland Security has advised the customers of digital sign maker Daktronics to “take defensive measures” following a series of cyberpranks on the company’s traffic signs.
The DHS action was prompted by the hack of a digital traffic sign in San Francisco that warned motorists of a “Godzilla Attack.” Meanwhile, a number of traffic signs across North Carolina started displaying “Hack By Sun Hacker.”
The DHS’ Industrial Control Systems Cyber Emergency Response Team cautioned cities and others using the signs to update access credentials and harden communications paths to the signs.
Traffic sign pranks may seem to be a minor annoyance, but it’s very likely they’re just the beginning of woes to come as the Internet of Things grows.
There will be 25 billion connected devices in the world by the end of next year, according to Cisco, and by 2020, that number will double to 50 billion.
Security for the Internet of Things will require a different mindset regarding default settings and the ability to deliver patches or manage configuration changes, observed Cisco TRAC manager Seth Hanford.
“When we are dealing with numerous devices like road signs, you can see from the ICS CERT advice some very simple things which will not scale securely in a future of myriad embedded devices,” he told TechNewsWorld.
Security surrounding IoT devices currently is weak. A simple scan of the Internet by a savvy hacker easily can identify many devices. Once discovered, the devices use default credentials on default management consoles. Under such conditions, those trying to secure the devices will quickly be overwhelmed.
“Instead of deploying systems with simplistic and well-known weaknesses like this,” Hanford said, “as experts informing the industries which will be producing the IoT devices of the future, security professionals need to be providing tools and architectures which allow ease of management in secure ways to industries whose expertise will not be with the computers on their embedded devices.”
Every Home a Hotspot
Would you like your home to be a public WiFi hotspot? If you’re a Comcast subscriber, you may not have much choice in the matter.
The cable provider last week turned 50,000 homes in Houston, Texas, into public hotspots through its Xfinity modems. Houston is just the beachhead for Comcast’s grand design to piggyback a public WiFi network on the Xfinity hardware in the homes of its customers.
Although Xfinity WiFi is supposed to be isolated from a homeowner’s WiFi, the users of Xfinity’s public network remain exposed to each other. Those users could be exploited by a hacker just as they could be if they were on any public network — from Starbucks to a hotel or an airport.
“Sharing home routers with strangers opens an attack surface to cybercriminals,” Craig Young, a router security expert with Tripwire, told TechNewsWorld.
“Even the best-secured devices can be penetrated, and home routers are typically not that well secured. If Comcast has included a backdoor for maintenance, it will eventually be exposed,” he said.
“Encouraging consumers to trust unencrypted public WiFi leaves them susceptible to an attacker replacing file downloads or embedding malware into Web page responses — both attacks that can be used for a variety of malicious purposes,” added Young. “The security industry has been advocating against the use of open WiFi for years.”
Outside Advice for Inside Job
Yet another point-of-sale system was breached last week. This time, the system belonged to restaurant chain P.F. Chang’s. The company still is investigating the breach, so it doesn’t know yet how many payment card numbers may have been stolen.
Chang’s knows about the problem only because the U.S. Secret Service informed it of the violation of its systems. That’s all too often the case in these kinds of incidents. A company goes along on its merry way until a third party tells it something is wrong.”P.F. Chang’s is yet another reminder that breaches are happening more and more from inside companies,” Eric Chiu, president and founder of HyTrust, told TechNewsWorld.
“Once an attacker is on your network, they have plenty of time to go after customer data, intellectual property or government secrets without being detected,” he said.
“That’s why companies are being told they have been breached versus detecting it themselves,” Chiu explained.
“Organizations need to shift to an inside-out model of security and assume the attacker is already on the network,” he added. “Critical systems and data need to be secured from the inside through access controls, role-based monitoring and data encryption.”
