More evidence that RIM can let governments monitor BlackBerrys

Monday, August 30th, 2010

RIM sidesteps BlackBerry ban in India | Signal Strength – CNET News.

According to the CNET article, the Indian government is going to put off shutting down BlackBerrys in their country while they study a RIM proposal to allow government monitoring of the communications.

Security of BlackBerry in question

Monday, August 9th, 2010

There has been a lot of media coverage of the threats of Saudi Arabia and the UAE to shut down BlackBerry connectivity in their countries unless RIM (the maker of BlackBerry) introduces a back door so they can monitor communications.

I have been following this story closely, but wanted to wait until I had all the facts before blogging about it. At this point I don’t think I am going to get the whole story. The statements I am seeing are absolutely contradictory and the whole thing is getting really fishy.

UAE/SA say that they need to be able to access BlackBerry communications, but they can’t.

RIM says that their technology makes interception impossible because the communications are encrypted end to end between the BES server (located at the users place of business) and the handset. RIM claims not to have access to the decryption keys.

Third parties claim that RIM has arrangements with other countries (including the US and Russia) which allows such access.

RIM responds that this is false and that they don’t have this ability.

It looks like RIM and UAE/SA will come to an agreement while both continue to claim that they have not compromised their positions.

The moral of this story is that you should not trust security you can not fully analyze yourself. Anonymizer Universal uses strongly encrypted L2TP VPN technology to secure your information so even if your telecommunications provider is cooperating with surveillance they still can’t read the contents of your messages.

Unfortunately Anonymizer Universal does not support BlackBerry yet, but iPhone, Windows, and Mac users are protected.

BBC News – Details of 100m Facebook users collected and published

BBC News – Details of 100m Facebook users collected and published

Ron Bowes wrote some software which scanned through Facebook to capture any unprotected personal information from the website.

The collected data has been compiled in to a huge file which is available over BitTorrent among other free channels.

While the program did not access any protected information, it has exposed any and all users who have not taken the proper steps to restrict access to their Facebook accounts, either through error or lack of knowledge, awareness or prudence.

The fact that it has been captured and distributed also makes it impossible to ever effectively change or remove any of the collected information. It is out there in the wild and out of anyones hands or ability to corral or correct.

This link will download the big (2.79GB) compressed database for you right now using a BitTorrent client (it may break at some point).

Facebook Session Hijack Video

Friday, July 2nd, 2010

We discovered a major security hole in Facebook almost by accident. The exploit is so trivial I can’t justify calling it hacking. Any time you are on an open WiFi and accessing Facebook, anyone else on the same network can easily grab your credential and access Facebook as you with full access to your account.

We have posted a video demonstrating this to YouTube as well as putting it in the Anonymizer Labs section of our website.

Google “Street View” vans intercepted sensitive data

Monday, June 21st, 2010

Cnet (among others) reports on Google’s interception of personal information from open WiFi nodes, including passwords and e-mail.

Clearly it was poor practice for Google to be capturing and recording such information as they drove around, but the real news should be that the information was there to be captured. The intent of the monitoring of WiFi seems to be collecting the locations of WiFi base stations to improve enhanced GPS location services. This works by having your device upload a list of all the WiFi base stations it can see (along with signal strength) which the service then looks up in a database to determine your location. This requires the service to have a database of the physical location of an enormous number of WiFi base stations.

To do this, all Google would have needed to capture was the hardware address of each device. Instead they captured some of the actual data being sent back and forth as well.

It turns out that this is incredibly easy. With many of the WiFi chipsets built in to personal computers, laptops and USB adapters, one can easily download free software that will start intercepting open WiFi traffic with a single click.

The shocking news should not be that Google accidentally got this information but that anyone with bad intent could do it to you. Anonymizer will soon be releasing a video we did a few weeks back showing how someone could take control of your Facebook account using an open WiFi and almost no technical expertise at all.

If the connection between you and a website, email server, or other service is un-encrypted, then anyone near you can intercept it if you are using an open WiFi.

To be clear, open WiFi means that the underlying connection is un-encrypted. Many public WiFi sites have a login page. This is to manage usage, and provides no security to you at all.

If you get a connection before you type in a password, especially if you see a web page before you type a password, then you should assume you are on an insecure connection and therefor vulnerable.

TOR may actually reduce your privacy

Wednesday, June 2nd, 2010

WikiLeaks seeded its database of documents by intercepting traffic through a TOR node they were operating.

This article at Wired highlights an almost buried section of this New Yorker interview with one of the founders of WikiLeaks.

Before the WikiLeaks site went live, the founders noticed that hackers were transferring stolen government documents over the TOR network. They captured over a million of these documents to form the initial core of the WikiLeaks archive.

This shows once again what I have been saying for a long time. Any privacy system that allows any untrusted and unknown person to become part of the infrastructure and have access to cleartext information is fundamentally flawed.

Any person with malicious intent can easily set up a TOR node and begin exactly the same kind of data collection that the WikiLeaks folks practiced.

Reputation is everything in this business. It is not practical for typical individuals to properly vet their providers. Track record, reputation, and respected third party endorsements are your best bet when choosing a privacy or security provider. Look for those for everyone who has access to your information.

Schneier on Security: Disabling Cars by Remote Control

This is just too good. It is a great example of where giving others power over your security, which they then centralize in a single place, leads to compromise with nasty failure modes.

In this case, a disgruntled former employee uses a system to disable over 1000 vehicles.

Privacy Network Tor Suffers Breach | Privacy Digest

Privacy Network Tor Suffers Breach | Privacy Digest

It has been reported, and the TOR folks have confirmed, that two of their core directory servers were recently compromised along with another server showing usage metrics. While it does not at first appear that the attack was aimed at compromising the TOR network, it would certainly have made some interesting attacks possible. Specifically, it looks like it would have allowed attackers to force users on to chains of all enemy run nodes. This is very concerning.

It also brings us the issue of general security of the TOR nodes. Since they are mostly run my volunteers, the security of the nodes is going to be very inconsistent. It is likely that many of them are vulnerable to attack which would give an adversary the ability to control a much larger fraction of the TOR network.

Google human rights accounts attacked from China

Tuesday, January 12th, 2010

Official Google Blog: A new approach to China

Google is officially stating that a number of email accounts hosted by Google were attacked from within China. The accounts seem to be mostly connected to Chinese human rights activists. They also state that this is part of a larger pattern extending over a number of other companies.

The most amazing thing about this is the very aggressive pro-privacy stance Google is taking in response to this. They are saying that they will stop censoring search results at Google.cn. That they will talk with the Chinese about how to do this, but are willing to completely pull out of operations in China if they can’t provide un-censored content from within.

The post is worth reading in full. Here are the concluding paragraphs:

These attacks and the surveillance they have uncovered–combined with the attempts over the past year to further limit free speech on the web–have led us to conclude that we should review the feasibility of our business operations in China. We have decided we are no longer willing to continue censoring our results on Google.cn, and so over the next few weeks we will be discussing with the Chinese government the basis on which we could operate an unfiltered search engine within the law, if at all. We recognize that this may well mean having to shut down Google.cn, and potentially our offices in China.

The decision to review our business operations in China has been incredibly hard, and we know that it will have potentially far-reaching consequences. We want to make clear that this move was driven by our executives in the United States, without the knowledge or involvement of our employees in China who have worked incredibly hard to make Google.cn the success it is today. We are committed to working responsibly to resolve the very difficult issues raised.

Wow. We shall see.

Huge vulnerability in encrypted USB drives

Tuesday, January 5th, 2010

NIST-certified USB Flash drives with hardware encryption cracked – The H Security: News and Features

Security firm SySS announced (in German) that it has discovered a massive vulnerability in the hardware encryption for USB thumb drives by Kingston, SanDisk and Verbatim. From the article at The H Security it looks like the problem is that all drives share a single symmetric encryption key at the hardware level. The password interface seems to simply do some gymnastics to get access to that key. It does not really matter what it does because SySS was able to intercept the actual hardware key being sent in the clear to the device.

They then simply wrote a little program to just send that key without bothering with the password or anything else. Because all drives by the same maker use the same key, this program can instantly open any encrypted USB drive by that maker.

From the sound of it, this is a very easy attack for someone to duplicate. If you have one of these drives, I would suggest that you treat them as if they were normal un-encrypted thumb drives.

Kudos to Kingston for quickly providing details of which of their drives are affected, and recalling them. SanDisk and Verbatim have issues software fixes. If I understand the attack correctly, I am not sure how a software patch will solve it, so watch this space.
