Security

Our devices are spilling our secrets

By Jake Edge
August 1, 2007

Recent news about a certain much-anticipated work of fiction being posted to the internet, in advance of its scheduled release, was not terribly surprising. The method used was, perhaps, a bit crude, and certainly time consuming, but it got the job done. Unbeknownst to the anonymous poster, their camera helpfully provided some extra information that might be used to track them down. Our devices are collecting all kinds of data about our habits and they are increasingly divulging that data in unexpected ways.

In the case of the Harry Potter book, the camera serial number was recorded in the Exchangeable image file format (Exif) data of the JPEG files of each page. Based on that information, Canon, the camera's manufacturer, may be able to match the camera to its original purchaser. If the camera has been serviced in the three years since it was released, that would also create an entry matching the serial number to the owner at that time. Neither of those conclusively links a person to the "crime", if it even is a crime, but they could give any investigators a good place to start.

It could have been a lot worse - some camera models have GPS capability built-in with Exif fields available to store that information on each shot. Perhaps the photo shoot happened deep enough inside some building that the GPS would not work, but over the hours it took to do that project, it seems quite possible that at least one shot would get tagged. It would be pretty easy to track down where the photos were taken if some were tagged with latitude and longitude coordinates. If it did not bring the police around, it certainly might have brought legions of Potter fans, eager to acquire the book early.

GPS data encoded into each photograph that you take, is a useful feature, keeping track of where the photos were taken some years down the road after (human) memory has failed. The other Exif data, much of which is detailed information about camera settings, is probably quite useful to photographers and is much simpler than trying to keep a record of exposure settings as you take pictures. Gathering and storing the data is quite helpful, it is the unexpected disclosure that causes problems.

It would be easy to ignore this problem, writing it off to an ignorant user, who should have scrubbed the Exif data before posting, but the problem comes in other guises as well. The US Secret Service evidently wants to be able to track your printer output, presumably as part of their anti-counterfeiting responsibilities, so they have convinced laser printer manufacturers to secretly add the now-famous yellow dots to each color page that is printed. Some of these codes have been cracked by the Electronic Frontier Foundation (EFF) and others, and have been found to contain model and serial numbers along with a timestamp of the print time.

It is much harder to blame ignorant users when the device manufacturer actively tries to hide the fact that identifying information is being leaked. Worse yet, it appears that inquiring about this practice and asking how to turn it off can lead to a visit from the Secret Service. There is nothing quite like a visit from a federal agent to stifle dissent. The folks at Seeing Yellow have lots more information, including a plan to overwhelm the agency through sheer numbers of people asking how to turn this "feature" off.

Imagine a world where the government required each person to carry a device that: knew its location via GPS, had the ability to take pictures and wireless connectivity. It is a scenario that would be ripe for abuse. In many ways, lots of people already, voluntarily, live in that world as cell phones have all those characteristics. It is not inconceivable that the cell phone manufacturers have already had a visit, from the Department of Homeland Security (DHS) or some other three-letter agency of the government, asking for help in the "War on Terror." The devices are certainly capable of reporting location (possibly with a helpful photo of people in the vicinity) back to the carrier and through them to the DHS. Probably, hopefully, that is not (yet?) happening, but there is no real technical barrier.

If we ratchet the paranoia level down a notch, cell phones, in particular smart phones, still pose an enormous target for the criminal world. Subverting phones that have cameras and GPS, to run them under the control of an attacker, makes an incredible surveillance tool. By using the same kinds of techniques that are used to spread viruses and spyware today, it should not be difficult to get targets to willingly perform actions that will lead to the subversion of their phone. From there, the attacker can get all of the call records, photos, calendar items and contacts while directing the phone to transmit its location every minute to the attacker.

Not only could this kind of information be used by stalkers, muggers and other criminals, this same capability could be used by lovers or employers to track people, keeping tabs on their movements and contacts. Rather than hire a private investigator, a jealous husband or wife might just borrow the other's phone, surf to a spyware site, and install a tracking program themselves. The opportunities are endless and exceedingly frightening for anyone concerned about privacy in today's world.

There are no easy answers on how to protect oneself against these unintentional data leaks. The organizations and individuals interested in collecting the data are doubly interested in concealing the fact that they are doing it, but, worse still, it is difficult for users to detect. If a cell phone is sending a short burst of encrypted information every minute, how would the average user, or even a sophisticated lab, detect and decode that data? If someone had not stumbled upon the yellow dots, we might be printing traceable documents, in blissful ignorance, to this day. What other, similar kinds of tracking are going on that we do not yet know about?

Free software can certainly help with this problem, but it is no panacea. Being able to replace the software in a device, with code that can be scrutinized and built before installing, is a good way to know what the device will do. Getting code that is vouched for by a trusted group, also serves to alleviate privacy leakage concerns. That is not the end of the story, unfortunately, as the hardware itself may be the culprit. Laser printer hardware is likely responsible for the identifying information in the output, making it rather difficult to replace. It is extremely difficult to know what the hardware in other devices might be doing behind our backs.

The truly paranoid will not be willing to trust any hardware they did not build themselves, perhaps from individual transistors, while trying to figure out how to trust the compiler. For the rest of us, open platforms, like OpenMoko, with free software and hardware, may provide reasons to believe that our data is protected; unless, of course, the device gets stolen or lost - encryption anyone?

Created:July 18, 2007 Updated:May 12, 2008
Description: shutdown and moz_bug_r_a4 reported two separate ways to modify an XPCNativeWrapper such that subsequent access by the browser would result in executing user-supplied code. (CVE-2007-3738)

Michal Zalewski reported that it was possible to bypass the same-origin checks and read from cached (wyciwyg) documents It is possible to access wyciwyg:// documents without proper same domain policy checks through the use of HTTP 302 redirects. This enables the attacker to steal sensitive data displayed on dynamically generated pages; perform cache poisoning; and execute own code or display own content with URL bar and SSL certificate data of the attacked page (URL spoofing++). (CVE-2007-3656)

Internet Explorer calls registered URL protocols without escaping quotes and may be used to pass unexpected and potentially dangerous data to the application that registers that URL Protocol. (CVE-2007-3670)

Ronald van den Heetkamp reported that a filename URL containing %00 (encoded null) can cause Firefox to interpret the file extension differently than the underlying Windows operating system potentially leading to unsafe actions such as running a program. This is only accessible locally. (CVE-2007-3285)

An attacker can use an element outside of a document to call an event handler allowing content to run arbitrary code with chrome privileges. (CVE-2007-3737)

Ronen Zilberman and Michal Zalewski both reported that it was possible to exploit a timing issue to inject content into about:blank frames in a page. When opening a window from a script, it is possible to spoof the content of the newly opened window's frames within a short time frame, while the window is loading. (CVE-2007-3089)

Mozilla contributor moz_bug_r_a4 demonstrated that the methods addEventListener and setTimeout could be used to inject script into another site in violation of the browser's same-origin policy. This could be used to access or modify private or valuable information from that other site. (CVE-2007-3736)

As part of the Firefox 2.0.0.5 update releases Mozilla developers fixed many bugs to improve the stability of the product. Some of these crashes that showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code. Note: Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript, such as large images.
