Hardware hacking a cat and mouse game

By JO TIMBUONG

TOOLS OF THE TRADE: Grand showing some of the tools hardware hackers use, which are available at affordable prices. He was one of the speakers at this year's Hack in The Box Security Conference.

IF YOU ask Joe Grand, president of Grand Idea Studio — an R&D and product design company, he’ll tell you that no piece of hardware can ever be safe enough from hackers.

“If something has electronics running inside, it can easily be tampered with, and many such products are susceptible to being compromised by even simple attacks,” he said.

According to him, hardware hacking has recently reappeared on hackers’ radars because of the plethora of easily available tips and tools available on the Internet.

He said the tools of the trade are very affordable and for a paltry sum experienced hardware hackers can have a die made of the circuit board they wish to hack.

This form of outsourcing is something new in the hardware hacking world, Grand said in his keynote address at the recent Hack in The Box Security Conference (HITBSecConf) here.

“Things that used to be difficult to do for hardware engineers and hackers have become so easy that there really isn’t any excuse now for hackers not to hack into hardware,” he said.

A mix of new and old methods can also help with the process of hacking hardware.

Citing an incident where he hacked into parking meters in San Francisco, Grand applied social engineering techniques to learn how the meters worked. “and the officials were only too happy to tell me everything.”

With that information and some software tools, he managed to confound the system running the parking meters into granting him US$999.99 (about RM3,600) worth of parking time.

“I didn’t use it, of course. I informed the city council about it and they are currently doing something to fix (the loophole in the) system,” he said.

Another trend that is making the job of a hardware hacker even easier is product enthusiasts disassembling a product and then posting detailed pictures of its components on the Internet.

“This shows hardware hackers what kind of components are used to build the product, which can clue them in to its vulnerabilities,” he said.

Good and bad

Just like with any other hacking activity, hardware hacking can lead to detrimental consequences, such as service theft or having your product cloned by unscrupulous parties.

But there is a silver lining, Grand said. If product developers make an effort to understand the skills of hardware hacking, they will be able to build a more secure product.

He said hardware designers usually leave a lot of clues on how to hack into a product because they are always in a hurry to put the devices on the market and place little emphasis on security.

Grand said hacked hardware is probably a more costly problem to solve than hacked software.

“In the software world all it takes is an inexpensive patch but it’s not that simple when it comes to hardware. A lot of times, it requires the companies to issue a new version of the hardware which can be a costly fix,” he said.

Having said that, Grand believes that it is impossible to devise a totally secure hardware product, no matter how much a company chooses to spend on this. The trick is for the company to keep staying ahead of the hackers.

“It’s a cat and mouse game. Hardware developers will try to make their products secure but there’ll always be an unplugged hole somewhere,” he said. This keeps everyone on their toes.

How Safe are Facebook Applications?

How Safe are Facebook Applications?

Written by Sarah Perez / October 16, 2009 7:21 AM / 4 Comments

Recently, Roger Thompson, chief research officer at security firm AVG, discovered over half a dozen Facebook applications that had been compromised by malicious hackers. Although the apps' reach was small with relatively few users being affected, Thompson was concerned because it was the first time he had seen apps themselves hacked as opposed to something like Facebook profile pages, a common target for the still-spreading Koobface worm.

While this incident alone wouldn't generate much excitement given the low-profile nature of the applications affected, it's not the only example of unsafe applications on Facebook. Another researcher just spent an entire month scouring Facebook apps for security vulnerabilities and what he found is disturbing: six of the hacked apps were in the top ten, 9700 applications were affected, and the potential victims totaled 218 million users.

Hacked Apps Found Forcing Malicious Software on Users

In the case of the hacked Facebook apps found by AVG, the apps had been compromised by the use of "iframes," which are bits of code embedded in the applications themselves. The iframes were able to load content from malicious websites into the applications' pages on Facebook.com, directing app users to install software on their computers by purporting to be an update for an out-of-date Adobe Reader product.

At first, Thompson thought the apps had been hacked by the developers, but as it turned out, it was the developers who were the victims. After looking at the source code for the apps in question, Thompson found that the iframes had been injected into the apps' code due to infected software on the developers' PCs.

Facebook quickly reacted to the situation and took down the compromised apps while also contacted the developers to warn them of the issue.

Thousands of Apps Vulnerable to Attacks

While hacked Facebook apps may still be a bit of a rarity today on the popular social network, security vulnerabilities that could lead to malicious attacks are not. After spending a month on Facebook looking for application bugs, another security researcher made some disturbing findings.

Specifically, the researcher, who goes only by the handle "theharmonyguy" online, was looking for a specific vulnerability he referred to as a "FAXX Hack." FAXX stands for "Facebook Application + XSS + XSRF" or, in other words, a cross-site scripting vulnerability - a certain type of security hole that could allow a hacker to access profile information, including personal details, status updates, and photos of a victimized user and their friends.

The findings showed that many Facebook applications, even those that were widely used and considered trustworthy, lacked basic security precautions. There were some 9700 Facebook applications which were affected by vulnerabilities and over half of the applications in question had passed through Facebook's "Verified Application" program, a sort of "stamp of approval" designed to assure Facebook users of an app's general trustworthiness. Among the apps, six were ranked in the top ten by monthly active users including FarmVille, Causes, LivingSocial, Movies, Farm Town, and YoVille. The collective monthly active users counts for all the hacked apps totaled 218 million. However, that previous figure does include overlaps. Also, seven of the top ten application developers on Facebook were found to host at least one vulnerable app.

While discovering the bugs, the researcher contacted each application developer to make him or her aware of the hole. For the most part, developers responded quickly and took the situation seriously. However, several developers took a while longer to respond. Nine took over a week to patch their application and one even took two weeks. And those delays were not due to the complexity of the required patches - these were, in terms of coding, simple fixes.

What's most concerning about these findings is how widespread the problem was. Unlike the apps AVG discovered, this wasn't a minor, isolated incident affecting a small handful of users. Although the apps in question here were just vulnerable to attacks as opposed to being comprised themselves, it shows how risky it is to use any application, Facebook Verified or not.

Is Any App Safe?

On top of all these security issues, in August many Facebook users were surprised to discover the vast amounts of personal information they were revealing by their use of Facebook quizzes. Even if you limit access to your profile through privacy settings, Facebook quiz applications can see everything on your profile page when you take a quiz...or even when your friend takes one. To make matters worse, Facebook does not screen developers for trustworthiness nor do they require developers to comply with a privacy policy.

With hacked apps, security vulnerabilities, lack of privacy policies, and apps that can read your private profile information, one has to wonder if using any Facebook application is appropriate and safe these days.

Hello World, I Love You from Tyler Knott Gregson on Vimeo.


Ok all of you amazing people out there, I need your help! I have this idea that I want to put together a video of as many people, in as many different languages as possible, saying “Hello World, I Love You.” So I need your help! If you can record video, please do it, if all you can do is record the sounds, that is fine too just send a photo with it, but I need your help, here’s how:

Please record a video or soundclip of you telling me anything you feel like telling me, I won’t include that in the video but I’d love to just hear from you too, but at the very end, if you could just record yourself saying “Hello World, I Love You,” in whatever languages you know how to speak, I would appreciate it more than I can express. I want to take all the video and sound clips and put them together with as many languages as possible and put them into one video, with all of US saying something so positive and unifying.

I need our help, so please, click the link above which will open up an email to me, or email me at: tylergregson(at)gmail(dot)com and just tell me what language you’re saying it in. “Hello World, I Love You.” Again, feel free to tell me anything else, I just want to hear all your voices.

Thanks and reblog away to spread the word!!
