Stupid Problem with BlackBerry Data

I use my mobile phones a lot and most batteries just barely last me through a day on a single charge. With my iPhone and Windows Phone, when the batteries are almost exhausted, various functions (including radios) are disabled to make the last bit of juice last as long as possible. My BlackBerry does the same thing.

I’m fine with this.

What’s I’m not fine with is the following: once I charge the BlackBerry and the radios are re-activated, I have to pull the battery and fully reboot the device to get access to the various services that course through the BIS. If I don’t pull the battery, I get a warning that my plan doesn’t cover data services and thus I cannot access the phone’s various Internet-related functions. On the face of things, it seems that after charging the device, RIM’s software fails to indicate to their network infrastructure that I have a data plan and thus can access the BIS.

Needless to say, this is absurd.

I cannot believe that I’m the only person running into this and regardless of whether the problem is with my particular carrier, or the device, it isn’t something that I should ever experience. These are the kinds of problems that should be sorted out well before a device is put in the consumer’s hands.

Self-Mutating Trojans Come to Android

Symantec is warning that the next generation of smartphone viruses has come:

Researchers from security vendor Symantec Corp. have identified a new premium-rate SMS Android Trojan horse that modifies its code every time it gets downloaded in order to bypass antivirus detection.

This technique is known as server-side polymorphism and has already existed in the world of desktop malware for many years, but mobile malware creators have only now begun to adopt it.

A special mechanism that runs on the distribution server modifies certain parts of the Trojan in order to ensure that every malicious app that gets downloaded is unique. This is different from local polymorphism where the malware modifies its own code every time it gets executed.

This is a clever means to avoid the rudimentary analysis systems that the major vendors use to ID malware. It’s also (another) indication of how important antivirus is going to become for the mobile marketplaces. I suspect that, by the end of the year, a lot of users (on iOS, Android, and the rest) are going to wish that the post-Steve Jobs smartphones on the market today met Jobs’ initial thoughts regarding smartphones when Apple released the iPhone. Specifically, he held that:

He didn’t want outsiders to create applications for the iPhone that could mess it up, infect it with viruses, or pollute its integrity

While our pocket computers are better now that apps are available, I can’t help but think that Jobs’ earliest worries are now looming at today’s potential nightmares.

Chrome Kills CA Revocation Checks

From Ars:

“While the benefits of online revocation checking are hard to find, the costs are clear: online revocation checks are slow and compromise privacy,” Langley added. That’s because the checks add a median time of 300 milliseconds and a mean of almost 1 second to page loads, making many websites reluctant to use SSL. Marlinspike and others have also complained that the services allow certificate authorities to compile logs of user IP addresses and the sites they visit over time.

Chrome will instead rely on its automatic update mechanism to maintain a list of certificates that have been revoked for security reasons. Langley called on certificate authorities to provide a list of revoked certificates that Google bots can automatically fetch. The time frame for the Chrome changes to go into effect are “on the order of months,” a Google spokesman said.

The problems with CA revocation checks have been particularly prominent over the past 12 months, given the large number of serious CA breaches. While even the Google fetch mechanism isn’t ideal – really, we need to move to an agile trust framework combined (ideally) with browser pinning that can’t be compromised by corporate admins – it’s better. Still, there’s a long way to go until SSL and the CA system are reformed to the point of being actual ‘trusted’ facets of the Internet.

The most important detail to focus on, is (per comment 12 by Brian Trzupek above) that Trustwave knew when it issued the certificate that it would be used to sign certificates for websites not owned by Trustwave’s corporate customer.

That is, Trustwave sold a certificate knowing that it would be used to perform active man-in-the-middle interception of HTTPS traffic.

This is very very different than the usual argument that is used to justify “legitimate” intermediate certificates: the corporate customer wants to generate lots of certs for internal servers that it owns.

Regardless of the fact that Trustwave has since realized that this is not a good business practice to be engaged in, the damage is done.

With root certificate power comes great responsibility. Trustwave has abused this power and trust, and so the appropriate punishment here is death (of its root certificate).

Wind on a Leaf: Dear startups and other relevant parties: It’s 2012. It is no longer ok to

chartier:

  • Not offer a way to download our data in some sort of a standard, transparent, and at least somewhat human-siftable format
  • Hide or otherwise be opaque about precisely what personal data you smuggle out of our devices
  • Not offer a one-to-two-click process for deleting our accounts
  • Fail to actually remove our data from your servers after we delete our accounts (while complying with applicable regional laws governing data retention)
  • Believe that taking VC and selling your customers’s private information is the only way to get a company off the ground, let alone run a successful business
  • Not use SSL for passing even the slightest bit of private information

Did I miss anything?

One thing: use rhetoric and spin to try and convince users that rabidly anti-consumer practices (such as those noted above) are good for society and that this kind of ‘radical transparency’ (i.e. screwing the customer for the benefit of the bottom line) is somehow going to make the world a better and happier place.

Phone hacking, for the most part, depends on remote access. Hackers obtain unprotected phone numbers from a variety of sources – Facebook must be a favorite – or by social engineering. PINs, for the most part, are easy to guess. Hacking typically takes place in the legitimate user’s absence.

Unless Apple or Google plans to bar remote access to devices, facial recognition security surely only solves a small part of the problem. Back to the drawing board.

iOS is a Security Vampire

I’m sorry, but what Path did is (in some jurisdictions, such as my own) arguably a criminal offence. Want to know what they’ve been up to?

When developer Arun Thampi started looking for a way to port photo and journaling software Path to Mac OS X, he noticed some curious data being sent from the Path iPhone app to the company’s servers. Looking closer, he realized that the app was actually collecting his entire address book — including full names, email addresses, and phone numbers — and uploading it to the central Path service. What’s more, the app hadn’t notified him that it would be collecting the information.

Path CEO Dave Morin responded quickly with an apology, saying that “we upload the address book to our servers in order to help the user find and connect to their friends and family on Path quickly and efficiently as well as to notify them when friends and family join Path. Nothing more.” He also said that the lack of opt-in was an iOS-specific problem that would be fixed by the end of the week. [emphasis added]

No: this isn’t an ‘iOS-specific problem’ it’s an ‘iOS lacks an appropriate security model and so we chose to abuse it problem’. I cannot, for the life of me, believe that Apple is willing to let developers access the contact book – with all of its attendant private data – without ever notifying the end user. Path should be tarred, feathered, and legally punished. This wasn’t an ‘accident’ but a deliberate decision, and there should be severe consequences for it.

Also: while the Verge author writes:

Thampi doesn’t think Path is doing anything untoward with the data, and many users don’t have a problem with Path keeping some record of address book contacts.

I think that this misses a broader point. You should not be able to disclose mass amounts of other people’s personal information without their consent. When I provide key contact information it is for an individual’s usage, not for them to share my information with a series of corporate actors to do whatever those actors want with it. The notion that a corporation would be so bold as to steal this personal information to use for their own purposes is absolutely, inexcusably, wrong.

Creative Something: The rules of a creators life

I’d suggest that these 9 principles are essential to guiding me through daily life. I would want to add a tenth item though:

10. Be willing to fail, and fail often, and just be sure to learn a little from each failed project.

MegaUpload’s Shutdown: Financial Implications for Artists

Mike Masnick points out something that a large portion of the media missed in initial discussions surrounding the MegaUpload seizures:

There’s a key point in all of this that we missed in our earlier analysis about paid accounts at Megaupload. In the indictment, the government seems to assume that paid accounts are clearly all about illegal infringing works. But that’s not always the case. In fact, plenty of big name artists – especially in the hip hop world – use the paid accounts to make themselves money. This is how they release tracks. You sign up for a paid account from services like Megaupload, which pay you if you get a ton of downloads. For big name artists, that’s easy: of course you get a ton of downloads. So it’s a great business model for artists: they get paid and their fans get music for free. Everyone wins. Oh… except for the old gatekeeper labels.

There were certainly a large number of files that were potentially infringing – with the ability to ascertain whether something is or isn’t infringing being impossible to conduct automatically using digital systems because of legal ambiguities – but there were also many clearly non-infringing files. Those that were directly uploaded by artists for download were amongst this latter category.

While some artists who have already made it big might suffer a decrease in revenue/earnings, but still enjoy a life dedicated to creating new works, those who have yet to ‘break through’ will suffer disproportionately from losing an easy-to-use service that could generate some revenue. The smallest artists lose, the largest lose, and consumers lose. I’m not even certain that the labels themselves ‘win’, insofar as generating bad will likely hinders their ability to establish strong (positive) brand relationships with prospective consumers.

Skype, the FBI, and MegaUpload

In the aftermath of the MegaUpload seizures we’ll hopefully learn more about how the FBI gained access to Skype transcripts. As reported by CNet:

The FBI cites alleged conversations between DotCom and his top lieutenants, including e-mail and Skype instant-messaging logs. Some of the records go back nearly five years, to MegaUpload’s earliest days as a cyberlocker service–even though Skype says “IM history messages will be stored for a maximum of 30 days” and the criminal investigation didn’t begin until a few months ago.

Sources told CNET yesterday that Skype, the Internet phone service now owned by Microsoft, was not asked by the feds to turn over information and was not served with legal process.

The U.S. Department of Justice told CNET that it obtained a judge’s approval before securing the correspondence, which wouldn’t have been necessary in the case of an informant. “Electronic evidence was obtained though search warrants, which are reviewed and approved by a U.S. court,” a spokesman for the U.S. Attorney for the Eastern District of Virginia said.

…

Skype saves chat records with contacts in a directory on the local hard drive, which could be accessed by FBI-planted spyware.

While it wouldn’t necessarily be surprising if spyware was used, it would be interesting to see more details of this come to public light. Moreover, was the spyware/electronic access authorization acquired in the US and then the malware implanted on computers in foreign jurisdictions, or did it target local (American) computers? If it was implanted on foreign computers, were local authorities aware of what was going on and did they have to give their approval?
