Internet of Things

Internet of ThingsOnce upon a time, there was a time when “using the Internet” always meant using a computer. Today getting on the intertubes is an expected feature for many devices. The next digital frontier is the physical world, where the “Internet of Things.” The Internet of Things will bring online ability to objects.

Twine Sensor Connects Household Objects to the Internet

Twine Tested.com notes a Kickstarter project from two MIT Media Lab alums who developed a way to make the Internet of Things more available. A small, durable “Twine” sensor listens to its environment and reports back over Wi-Fi. The creators hope their new product will let regular users, even those without programming knowledge, digitally manage their surroundings.

A basic Twine unit senses temperature and motion, but other options like moisture detection, a magnetic switch, and more can be added using a breakout board. The various sensors and built-in Wi-Fi can be powered by either a mini-USB connection or two AAA batteries, which will keep it running for months. Twine readings get wirelessly loaded into the appropriately named Spool web app, where users can set simple if-then triggers that create SMS messages, tweets, emails, or specially configured HTTP requests.

For a donation of $99 or more will get you a basic unit when they ship in March.

THE SMART FRRRIDGE. Chilly Forecast for Internet Frrridge

Internet FridgeThe Smart Frrridge is a new version of the familiar kitchen apparatus. According to Medienturn the new fridge comes with a built-in computer that can be connected to the internet. It is one of a growing class known as “internet appliances” that include not only smart phones, but also web-enabled versions of typical household appliances.

The refrigerator keeps an eye on the food in it by using RFID technology, a digital camera and image processing. These technologies allow the fridge to keep track of whats in it, how long has this been there, should it be trashed?

To keep in contact with the Smart Frrridge all you have to do is to pick up your mobile phone and call. It will be able to suggest a menu that uses the foods inside, and generate a shopping list of the missing ingredients and place the order online.

The Smart Frrridge cab also be used to watch television, listen to music, to take a photograph, save it to an album, or post it to a website, or send it to an email recipient. The comes with a docking station you can just dock in your Apple (AAPL) iPod or iPhone and start using all your favorite cooking apps.

SCADA: How Big a Threat?

Cyber attackerThere are reports of two recent cyber attacks on critical infrastructure in the US. Threatpost says the hacker who compromised the water infrastructure for South Houston, TX, said the district used a three-letter password, making it easy to break in.

There are also reports that a cyber attack destroyed a water pump belonging to a Springfield, IL water utility. There are mixed reports that an attacker gained unauthorized access to that company’s industrial control system.

According to DailyWireless, Supervisory Control And Data Acquisition (SCADA) software monitors and controls various industrial processes, some of which are considered critical infrastructure.

Researchers have warned about attacks on critical infrastructure for some time, but warnings became reality after a highly complicated computer worm, Stuxnet, attacked and destroyed centrifuges at a uranium enrichment facility in Iran.

German cybersecurity expert Ralph Langner found Stuxnet, the most advanced worm he had ever seen. The cybersecurity expert warns that U.S. utility companies are not ready to deal with the threat.

In a TED Talk Langner stated that, “The leading force behind Stuxnet is the cyber superpower – there is only one; and that’s the United States.”

In a recent speech at the Brookings Institution, he also made the bigger point that having developed Stuxnet as a computer weapon, the United States has in effect introduced it into the world’s cyber-arsenal.

New NIST Report Sheds Some Light On Security Of The Smart Grid

NIST DarkReading reports the National Institute of Standards and Technology (NIST) released a report (PDF) by the Cyber Security Coordination Task Group. The report from the Task Group which heads up the security strategy and architecture for the nation’s smart power grid includes risk assessment, security priorities, as well as privacy issues.

The smart grid makes the electrical power grid a two-way flow of data and electricity allows consumers to remotely monitor their power usage in real-time to help conserve energy and save money. DarkReading says researchers have raised red flags about the security of the smart grid. Some have already poked holes in the grid, including IOActive researcher Mike Davis, found multiple vulnerabilities in smart meters, including devices that don’t use encryption nor do they authenticate users when updating software. He who was able to execute buffer overflow attacks and unleash rootkits on smart meters.

Tony Flick, a smart grid expert with FYRM Associates, at Black Hat USA talked (PDF) about his worries over utilities “self-policing” their implementations of the security framework. “This is history repeating itself,” Mr. Flick said in an interview with DarkReading.

According to DarkReading, the report recommends smart grid vendors carry out some pretty basic security practices:

  • Audit personally identifiable information (PII) data access and changes;
  • Specify the purpose for collecting, using, retaining, and sharing PII;
  • Collect only PII data that’s needed;
  • Anonymize PII data where possible and keep it only as long as necessary;
  • Advanced Metering Infrastructure (AMI) must set up protections against denial-of-service (DoS) attacks;
  • Network perimeter devices should filter certain types of packets to protect devices on an organization’s internal network from being directly affected by denial-of-service attacks;
  • The AMI system should use redundancy or excess capacity to reduce the impact of a DoS;
  • AMI components accessible to the public, must be in separate subnetworks with separate physical network interfaces;
  • The AMI system shall deny network traffic by default and allows network traffic by exception;
  • Consumers’ access to smart grid meters be limited. Authorization and access levels need to be carefully considered.

 

Adobe Notes

Malicious PDF Files Becoming the Attack Vector of Choice

Adobe PDF ZDNet points out a report from Symantec’s MessageLabs that malicious PDF files outpace other malicious attachments used in targeted attacks and now represent the attack vector of choice for malicious attackers compared to media, help files, HTMLs and executables.

The report says that office-based file formats are a popular and effective choice used in some targeted attacks. Cybercriminals attempt to bypass spam and email filters by distributing the ubiquitous PDF that’s often allow to pass through these layers of protection. In 2009, about 52.6% of targeted attacks used PDF exploits, compared with 65.0% in 2010, an increase of 12.4%. MessageLabs Intelligence Senior Analyst, Paul Wood says,

PDF-based targeted attacks are here to stay, and are predicted to worsen as malware authors continue to innovate in the delivery, construction and obfuscation of the techniques necessary for this type of malware

Adobe Posts Its First Billion-Dollar Quarter

Adobe profitThe New York Times reports that the software maker Adobe posted its first $1 billion quarter in Q4-2010. Revenue rose 33 percent to $1.01 billion from $757 million last year. Adobe, which is based in San José, CA makes Photoshop, Acrobat and Flash software.

Targeted attacks exploiting PDF bugs are soaring

Adobe bugs Help Net Security reports that Adobe is having a hard time fighting its bad reputation when it comes to products riddled with vulnerabilities. Help Net Security references a report from F-Secure’s Lab which says that Adobe Reader exploits are becoming the weapon of choice for many cybercriminals.

This makes patching and updating eminently important. As an example the latest critical vulnerability (CVE-2010-0188) which Adobe warned users to update the software to the latest version. Users who missed the memo are vulnerable, F-Secure (FSC1V) warns it is being exploited in the wild.

F-SecureUpon loading the PDF file, an embedded executable is dropped on the victim’s hard disc and it immediately tries to connect with tiantian dot ninth dot biz to download other files.

F-Secure has warned long ago about security problems plaguing Adobe’s most famous software. The security firm has even advised users to start using an alternative PDF reader. According to Help Net Security Adobe’s, decision to schedule their updates to follow Microsoft’s Patch Tuesday is a step in the right direction.

Malicious PDF spam with Sality virus

Malicious PDF spam with Sality virusHelp Net Security highlightsSophos warning that a malicious email containing the following text has been dropped into inboxes around the world:

Hey man..
Remember all those long distance phone calls we made.
Well I got my telephone bill and WOW.
Please help me and look at the bill see which calls where yours ok..

SophosYou surely don’t remember such an occurrence or the sender of the email, since this is just a ploy to make you open the PhoneCalls.pdf attachment, but don’t let your innate curiosity get the better of you.

The attached file  can exploit a vulnerability in how Adobe Reader handles TIFF images, and proceeds to download and execute a Trojan that loads the Sality virus into your system’s memory. The virus then proceeds to append its encrypted code to executable files, deploys a rootkit and kills anti-virus applications.

Sophos reminds everyone that opening documents attached to unsolicited emails is like the online equivalent of Russian roulette – the odds are stacked heavily against you.

Adobe, The New King Of Security Holes

Adobe Patches Critical Security Hole in Acrobat, Reader, and FlashInformation Week reports that Microsoft (MSFT) has spent more than a decade improving its secure software development and its response to security exploits. As a result, Microsoft is losing the lead in security vulnerabilities and being replaced by Adobe (ADBE).

With Microsoft’s improved response to security holes, the pickings in Windows itself are getting slimmer. Attackers don’t have brand loyalty, so they’ve moved on to another company with lots of PC installed base: Adobe. Security holes are being exploited in Adobe Reader and Illustrator . Adobe makes this problem worse because it has been bundling unwanted applications and their AIR software platform with their free applications like Adobe Reader. Adobe is looking to create an attractive installed base for their developers, but they are also creating an attractive attack surface for the bad guys.

Protecting yourself from Adobe’s security holes can be difficult.  There are non-Adobe solutions such as Foxit Reader, which is much faster and lighter than Adobe Reader but has had problems with  PDF documents with editable fields. InfoWeek provided some specific tips that may help avoid security problems.

  • Uninstall any Adobe Reader version earlier than 9,  and install version 9.
  • With ver. 9 go to the Edit/Preferences menu. Make sure that Security(Enhanced) is turned on; (Adobe ships it turned off).
  • Launch the Updater and be sure you’re checking for updates, install updates ASAP.
  • Go to Trust Manager and uncheck the option for “Allow opening of non-PDF file attachments.”
  • Finally, unless you know you need Javascript in your Acrobat documents, disable Javascript.
  • RB- Don’t go to ver. 10, I hate it.
