Anti-forensic mobile OS gets your phone to lie for you

In Android Anti-forensics: Modifying CyanogenMod Karl-Johan Karlsson and William Bradley Glisson present a version of the Cyanogenmod alternate operating system for Android devices, modified so that it generates plausible false data to foil forensic analysis by law enforcement. The idea is to create a mobile phone that "lies" for you so that adversaries who coerce you into letting them take a copy of its data can't find out where you've been, who you've been talking to, or what you've been talking about.

I'm interested in this project but wonder about how to make it practical for daily use. Presently, it maintains a hidden set of true data, and a trick set of false data intended to be fetched by forensic tools. Presumably, this only works until the forensic tools are modified to spot the real data. But you can conceptually imagine a phone that maintains a normal address book and SMS history, etc -- all the things that are useful to have in daily use -- but that, on a certain signal (say, when an alternate unlock code is entered, or after a certain number of failed unlock attempts) scrubs all that and replaces it with plausible deniability data.

Obviously, this kind of thing doesn't work against state-level actors who can subpoena (or coerce) your location data and call history from your carrier, but those people don't need to seize your phone in the first place.

Apple adds privacy-protecting MAC spoofing (when Aaron Swartz did it, it was evidence of criminality)

Apple has announced that it will spoof the MAC addresses emitted by its wireless devices as an anti-tracking measure, a change that, while welcome, is "an umbrella in a hurricane" according to a good technical explainer by the Electronic Frontier Foundation's Jeremy Gillula and Seth Schoen.

Crowdfunding mass FOIA requests on police use of "Stingray" warrantless spying devices

Michael from Muckrock sez, "After scouring American police departments (via public records requests) for drone usage, MuckRock is setting its sights a little lower with a crowdfunding campaign hoping to fund thousands of public records request on how local agencies are using fake cell phone towers, warrantless wiretaps, and other techniques to get your cell phone to phone home."

Turn on your data for one minute, AT&T sticks you with a $750 international roaming charge


Jeff writes, "I learned this week that it's possible to run up a $750 international data roaming bill in one minute on AT&T. I managed to convince AT&T to forgive the charges after two days and 40 minutes of phone calls but the best guess at how this happened is kind of alarming. It seems that AT&T's billing system sometimes bundles US traffic with international traffic." Jeff was driving in the Pacific northwest, near the Canadian border.

US Marshals raid Florida cops to prevent release of records of "stingray" surveillance


US Marshals swept into the offices of police in Sarasota, Florida to whisk away records related to operation of "stingray" surveillance tools that the ACLU had requested. The records detailed the farcically low standard for judicial permission to use a stingray (which captures information about the movements, communications and identities of all the people using mobile phones in range of them), and is part of a wider inquiry to their use without a warrant at all -- at least 200 Florida stingray deployments were undertaken without judicial oversight because the police had signed a nondisclosure agreement with the device's manufacturer and they decided that this meant they didn't have to get warrants anymore.

The ACLU has seen a lot of shenanigans in respect of its campaign to document the use and abuse of stingrays, but this is a cake-taker: "We’ve seen our fair share of federal government attempts to keep records about stingrays secret, but we’ve never seen an actual physical raid on state records in order to conceal them from public view."

Nokia 100 phones: £5

The workhorse Nokia 100 phone is now a mere £5 without contract from Carphone Warehouse. Now, that's a cheap burner -- either manufacturing robots have come way down in price or there's some very unhappy people chained to machines in a factory somewhere. Either way, it's a pretty sad end for a giant whack of conflict minerals like coltan mud. (via Red Ferret)

App lets you auction your San Francisco parking spot

A new mobile app called Monkeyparking allows people in San Francisco with good parking spots to auction them off when they're ready to leave, permitting circling rich people to engage in excitingly dangerous class warfare by bidding on spaces with their phones while they drive. The app's creators defend it as providing an "incentive" to leave your space for others to use.

NYT to SCOTUS: Cops should get warrant before searching your cellphone after arrest

From an editorial by the New York Times editorial board:

On Tuesday, the Supreme Court will consider whether law enforcement officers during an arrest may search the contents of a person’s mobile phone without a warrant. The court should recognize that new technologies do not alter basic Fourth Amendment principles, and should require a judicial warrant in such circumstances.

USB recharger battery that can also jumpstart your car

Junopower is advertising presales of a portable device-charging USB battery called the "Jumpr" that can discharge its stored power at 300 amps, which is sufficient to jumpstart many automobile engines. They're billing it as a pocket-sized, 7 oz alternative to the trunk-sized emergency jumpstart kits that also recharges your phones and tablets. Pre-orders are $70 and they're promising shipments some time in May.

Google's Project Ara: a click-in/click-out modular concept phone


Modular mobile phone design feels important; I've been excited about the idea since Xeni posted about Phonebloks last September. Now, Google and New Deal Design have floated a concept for a modular Android phone ecosystem called Project Ara that's got me even more worked up. Project Ara lets you swap modules (batteries, radios, cameras, screens, etc) around between "exoskeletons." They call it an "ecosystem" because third parties are meant to be able to supply their own modules for an open spec.

A good overview in Wired discusses the possibilities this opens up (night vision, 3D imaging, biometrics) but I'm more interested in the possibilities for surveillance-resistant open source hardware, and hot-swapping modules that lock phones into carriers. Plus, as a serial phone-shatterer, I love the idea of being able to click out a busted screen and click in a fresh one.

I've seen several artists create "mobile phone orchestras" but I appreciate the multigenerational representation in this example made for SK Telecom, the South Korean wireless operator.

Samsung Galaxy back-door allows for over-the-air filesystem access


Developers from the Replicant project (a free Android offshoot) have documented a serious software back-door in Samsung's Android phones, which "provides remote access to the data stored on the device." They believe it is "likely" that the backdoor could provide "over-the-air remote control" to "access the phone's file system."

At issue is Samsung's proprietary IPC protocol, used in its modems. This protocol implements a set of commands called "RFS commands." The Replicant team says that it can't find "any particular legitimacy nor relevant use-case" for adding these commands, but adds that "it is possible that these were added for legitimate purposes, without the intent of doing harm by providing a back-door. Nevertheless, the result is the same and it allows the modem to access the phone's storage."

The Replicant site includes proof-of-concept sourcecode for a program that will access the file-system over the modem. Replicant has created a replacement for the relevant Samsung software that does not allow for back-door access.

Firefox OS and the unserved billions of the developing world

Last month, I wrote about the announcement of the $25 Firefox OS smartphone, aimed at developing world users who have never owned a smartphone and can't afford a high-end mobile device. An editorial by Pascal-Emmanuel Gobry describes how such a device could find an audience of billions, and spur a new ecosystem of developing world developers who make software that's geared not just to the Firefox OS platform, but also to the unique needs of people in the developing world.

The vision of Firefox OS is a contrast to the Zuckerberg plan to supply "Internet" to poor people in the form of an ad-subsidized, all-surveilling walled garden. As Susan Crawford says, "That's not the Internet -- that’s being fodder for someone else's ad-targeting business. That's entrenching and amplifying existing inequalities and contributing to poverty of imagination -- a crucial limitation on human life."

Asking whether the Internet is good or bad for freedom misses the point. It's clear that network technologies have the power to track and control their users, and the power to free and enrich them. The right question to ask is: "How do we get an Internet that does more for freedom?"

Firefox OS sounds like part of the answer.

King no longer claims to own "candy," still claims it owns "saga"

King Games, makers of Candy Crush, have backed down from their insane campaign to trademark the use of "Candy" in connection with games, a gambit that brought them ridicule and opprobrium (for example, a game jam where all the games made use of "candy"), not least because the company bullied competitors who had created candy-themed games years before Candy Crush came to market. However, the company still asserts a trademark over the use of the word "saga" in connection with games, and is trying to shut down The Banner Saga. Cory 21

Boeing's self-destructing, tamper-resistant spookphone: the Black


Boeing has sought regulatory approval from the FCC for a tamper-resistant phone intended to self-destruct if its case is opened. The phone, called "Black," runs Android, and is intended for use under the DoD Mobile Classified Capabilities guidelines. It will be sold with a nondisclosure agreement prohibiting tampering or service, and opening the case will trigger a system intended to wipe the phone's data.

Interestingly, it has a removable battery (something that's become increasingly scarce in smartphones). Best operational security practice holds that you should remove your phone's battery when you want to be sure that it's off, because any malware that turned your phone into a bug could also cause it to simulate being switched off while it remained running.

It's an intriguing technical problem. I'm intuitively skeptical of the security model. I can believe that this phone will be tamper-evident, but I don't know if it will be all that tamper-resistant. That is, it may be capable of preventing an attacker from surreptitiously opening the case to access the components, but how about an adversary willing to simply smash the screen to get at the components beneath?

The manufacturer could make a phone whose accelerometer tried to detect these events and wipe the device as a precaution, but I suspect there'd be a lot of spooks who'd end up cursing their self-destructing phones every time they butterfingered them while getting them out of a pocket while walking down the street. I'm pretty sure that I can use tools to remove my phone's screen in a way that generates less detectable stress than it receives during everyday knockabout and drops.
