Internet of (not necessarily necessary) Things

[Many of the Things that crop up on this page may indeed be necessary. But that doesn’t mean that connecting them to the Internet of Things (or even the Internet of Everything) is necessary, or even desirable, given how often that connectivity widens the attack surface.]

Infoblox have a very interesting report on What is Lurking on Your Network – Exposing the threat of shadow devices.

In his foreword, Gary Cox says:

“For IT departments, the complexities and security issues around managing BYOD schemes and unsanctioned Shadow IT operations have long been a cause for concern.

“In an increasingly complex, connected world, this challenge has now been exacerbated by the explosion in the number of personal devices individuals own, as well as the plethora of new IoT devices being added to the network.”

More reasons to feel uncomfortable with the unfettered enthusiasm for BYOD.

Commentary/summary from Help Net Security: Exposing the threat of shadow devices: “Employees in the US and UK admitted to connecting to the enterprise network for a number of reasons, including to access social media (39 percent), as well as to download apps, games and films … These practices open organizations up to social engineering hacks, phishing and malware injection.”

(1) Brian Krebs talks about the asymmetry in cost and incentives when IoT devices are recruited for DDoS attacks like one conducted against his site: Study: Attack on KrebsOnSecurity Cost IoT Device Owners $323K.

He observes: “The attacker who wanted to clobber my site paid a few hundred dollars to rent a tiny portion of a much bigger Mirai crime machine. That attack would likely have cost millions of dollars to mitigate. The consumers in possession of the IoT devices that did the attacking probably realized a few dollars in losses each, if that. Perhaps forever unmeasured are the many Web sites and Internet users whose connection speeds are often collateral damage in DDoS attacks.”

Some of his conclusions are based on a paper from researchers at University of California, Berkeley School of Information: the very interesting report “rIoT: Quantifying Consumer Costs of Insecure Internet of Things Devices.

(2) Product test specialists AV-Test conducted research into the security of a number of fitness trackers (plus the multi-functional Apple watch: Fitness Trackers – 13 Wearables in a Security Test. On this occasion, the results are fairly encouraging.

(3) Bleeping Computer: 5,000 Routers With No Telnet Password. Nothing to See Here! Move Along! – “The researcher pointed us to one of the router’s manuals which suggests the devices come with a passwordless Telnet service by default, meaning users must configure one themselves.”

Sophos: Half a million pacemakers need a security patch – refers to the FDA-approved firmware patch for Abbot pacemakers. “In September 2016, the company sued Internet of Things (IoT) security firm MedSec for defamation after it published what St Jude said was bogus information about bugs in its equipment … security consultants at Bishop Fox confirmed the validity of MedSec’s findings. The company begrudgingly stopped fighting and litigating and issued security fixes.

Graham Cluley: The NSA wants its algorithms to be a global IoT standard. But they’re simply not trusted – “Why were the algorithms – known as Simon and Speck, and – rejected? It seems because … [they] might contain encryption backdoors that would be abused by US authorities.” I’ve always tended to mistrust standards espoused by professional politicians, who are rarely as knowledgeable on security issues as they would have us believe. Film and TV makers are often deeply mistrustful of government agencies – conspiracy theories make good drama. And in recent years, that mistrust has been reinforced by real news. It’s no wonder if people fear that the Internet of Things will tip into 1984 telescreens. But perhaps they should be at least as distrustful of the private sector.

The Register: Princeton research team hunting down IoT security blunders – “IoT Inspector is currently at the data-gathering stage, with the aim of launching an open source tool for users to get some idea of what their devices are doing.”

Bleeping Computer: Ski Lift in Austria Left Control Panel Open on the Internet – “Officials from the city of Innsbruck in Austria have shut down a local ski lift after two security researchers found its control panel open wide on the Internet, and allowing anyone to take control of the ski lift’s operational settings.”

National Cyber Security Centre: Advisory: Russian State-Sponsored
Cyber Actors Targeting Network Infrastructure Devices
“Since 2015, the US and UK Governments have received information from multiple sources including private and public sector cybersecurity research organisations and allies that cyber actors are exploiting large numbers of enterprise-class and SOHO/residential routers and switches worldwide. The US and UK Governments assess that cyber actors supported by the Russian government carried out this worldwide campaign. These operations enable espionage and intellectual property that supports the Russian Federation’s national security and economic goals.”
