Internet of (not necessarily necessary) Things

[Many of the Things that crop up on this page are indeed necessary – you may not be able to read this without a router. 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. And sometimes even necessary devices entail security risks.]

The Register: So you’re doing an IoT project. Cute. Let’s start with the basics: Security – “And for heaven’s sake, don’t fall in love with the data…Data is seen as one of IoT’s biggest payoffs – generating and gathering it to help your business. But get IoT wrong, and you stand to be overwhelmed by that data wave. Cisco estimates IoT will generate 500 zetabytes of data by the end of 2019…”

ADB.Miner and a continuing vulnerability affecting Android devices (not just phones).

“Unfortunately, vendors have been shipping products with Android Debug Bridge enabled. It listens on port 5555, and enables anybody to connect over the internet to a device. It is also clear some people are insecurely rooting their devices, too.” He cites the following from Android’s developer portal:

“The adb command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.”

“The ADB.Miner worm exploited the Android Debug Bridge (ADB) … used for troubleshooting faulty devices …  some vendors have been shipping Android-based devices where the ADB over WiFi feature has been left enabled in the production version…”

“The Z-Wave wireless communications protocol used for some IoT/smart devices is vulnerable to a downgrade attack … the attack —codenamed Z-Shave— relies on tricking two smart devices that are pairing into thinking one of them does not support the newer S-Wave S2 security features, forcing both to use the older S0 security standard.”

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.

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.
