Hands on (literally): the two Tor “travel router” contenders, Anonabox (left) and InvizBox (right), are accessible to burrow your Internet wanderings.
A while back, we covered the altercation over a few Kickstarter projects aiming to accommodate article in accretion appeal as of late: a foolproof way to affix any Wi-Fi able accessory to the Tor anonymized network. Two such Tor “travel router” projects accept aback become absolute product: InvizBox, from a aggregation in Ireland, and the adored Anonabox, which was acquired by the tech captivation aggregation Sochule. A third, the accessible antecedent PORTAL project, originally coded by “opsec” best the grugq, is actuality angry into a chump artefact by Ryan Lackey and Marc Rogers of CloudFlare and will be getting its bow at the RSA Conference afterwards this month.
These accessories are, to capricious degrees, able means to adumbrate from exceptionable absorption of all sorts. That is, they’ll assignment abbreviate of a accompaniment amateur attractive to use a behemothic datacenter committed to assuming all abode of de-anonymizing attacks by application the Tor takeover cabal archetypal of the week, zero-day malware, or people’s own simple mistakes adjoin them. But these routers all chase hardly altered approaches. Anonabox is a stunningly hands-off artefact that has no user interface added than its diffuse Wi-Fi password; InvizBox provides hands-off aloofness with the accession of an authoritative interface to administer fixes and advantage moderately added complicated Tor capabilities; and PORTAL promises to accommodate everything—including pluggable protocols for Tor to advice it get accomplished the best assiduous state-funded nastiness.
We don’t accept PORTAL in duke yet, but we did accept analysis units of Anonabox and InvizBox. To see aloof how able those two abridged aloofness contenders are, we ran them through a head-to-head in the best adverse arrangement ambiance we apperceive of—Ars Technology Lab’s arrangement ache alcove (otherwise accepted as my office… I’ve had to do a bit of amenable acknowledgment forth the way).
The basal band is that these two accessories do work. Both accommodate a way to affix PCs and added accessories to the Tor arrangement and admission “hidden services” and the beyond Internet afterwards accepting to install and advance software. Both are based on OpenWRT, the Linux-based accessible antecedent operating arrangement for anchored accessories that is frequently acclimated in Wi-Fi routers.
But admitting application about the aforementioned technology as a base, these two accessories decidedly bend in their approach. Your aloofness breadth may alter as a result, decidedly with Anonabox. For example, there’s no way for the end-user of an Anonabox to accomplish patching or upgrades to actual faults in the basal code.
There are abounding affidavit why anyone ability appetite to use Tor. An accretion cardinal of countries adviser Internet cartage today (including Australia, with its contempo across-the-board abstracts assimilation law that calls for boundless accumulating of Internet metadata). And while the use of basic clandestine networks to assure aloofness is in abounding cases a bigger advantage than Tor, accessing VPNs in countries adverse to aloofness is frequently difficult. Journalists, political activists, academics, and anyone absent to artlessly use the Internet afterwards surveillance from an ISP, a company, or a government bureau needs Tor.
Tor is best able aback it is consistently acclimated by people for accustomed things (and aback there are added bodies accommodating to put up broadcast and avenue servers). Accustomed that there are assertive fingerprints associated with Tor use that can be articular by abysmal packet analysis rules, an eyewitness can acquaint aback you’re application Tor; it’s easier to adumbrate action if Tor is consistently on and in use by many. If you aloof about-face on Tor aback you’re logging in to your aphotic bazaar admin console, that can become ambiguous for anonymity.
There are some trade-offs. Tor is carefully a TCP/IP service, which makes it accomplished for visiting websites, blockage e-mail, and any added assignment that relies on the three-step handshake of the Transmission Control Agreement to accomplish abiding aggregate gets area it’s declared to. But you can’t use Tor for things that stream—like Skype or added articulation and video applications, for example. Those use the handshake-less UDP agreement to bandy their packets as bound as accessible beyond the Internet. (Anybody who says they accept ‘Skyped’ over Tor for aegis doesn’t accept how Skype works.)
Tor is additionally not abundant if you appetite speed. The Tor network’s throughput depends on the accommodation of the broadcast and avenue nodes that are complete into the “circuit” acclimated for anniversary connection. Application the Tor Browser Bundle on a test arrangement and the two routers activated in this review, we got upload and download speeds alignment from almost a megabit per additional (using the Tor Browser Bundle) to 2.5 megabits per second.
And usually, application Tor is not article that could be declared as “foolproof.” It requires patches regularly—often anon aback a aegis affair is uncovered. The Tor Browser Bundle and the USB-bootable operating arrangement TAILS are incremental accomplish abroad from the abundance area of the boilerplate computer user.
That’s area the Anonabox and the InvizBox appear in. Nearly identical in admeasurement and anatomy agency and altered evidently alone in the adjustment of Ethernet and ability ports, these accessories appear in boxes closed with tamper-sensitive band to assure the chump from en-route analytical (or at atomic accession said analytical to the akin of addition with affected tamper-proof band of their own). Both can be acclimated via an Ethernet cable or Wi-Fi, and they defended the Wi-Fi arresting with WPA2 (though aboriginal versions of Anonabox alien with unencrypted Wi-Fi). Both crave an Ethernet affiliation to the “Wide-Area Network” side—the Internet-connected arrangement that will host the outbound Tor connection. And you can ability either accessory over USB from a anthology PC or a accepted ability antecedent (not included).
From there on out, however, your best matters.
Aggregate that’s in the box for Anonabox (minus the countersign sticker)—Anonabox itself, a USB cable for power, a quick guide, and a promotional sticker.
One end has an Ethernet anchorage to affix to your LAN (or anon to your PC)…
And the added has an Ethernet anchorage to affix to your Internet router or whatever arrangement you’re application to admission the Internet.
The audacity of the Anonabox- a custom board? There are no anecdotic marks.
The basal of the guts.
Anonabox is intended, as its developer August Germar told Ars, for a actual specific use case. Measuring 64 millimeters wide, 44.5 millimeters deep, and 22.3 millimeters high, the accessory is “based on a assertive set of ideas,” and those account are that you bung the box in and you log into it with the countersign you are accustomed over Wi-Fi or aloof jack into its LAN Ethernet port. From there, users must be blessed (or pretend to be) with the Tor aegis you get and balloon all about it. Anonabox will automatically administer Tor software updates and handle all that blowzy networking actuality afterwards users getting involved.
There is not abundant advice accessible about what’s central the Anonabox, so I performed an crooked acreage modification to acquisition out, application a screwdriver to pop accessible the case. The lath appears to be “custom”—there’s no mark on it anywhere to analyze nation of agent or manufacturer, admitting it has a MIPS-based Atheros AR9331-AL3A Wi-Fi system-on-chip and an SK hynix DDR2 RAM chip. (See the arcade aloft for photos.) It runs on 5 volts/1 amp, so it can be powered calmly from any USB-based charger or from a PC’s USB port. Some readers accept remarked that it appears to be an unbranded Oolite board, and it appears that the FCC identifier on the Anonabox was assigned to the aforementioned architect as that of the Oolite: Gainstrong Industry Co., Ltd of Shenzen, China.
Update: It appears that the Anonabox may aloof accept a custom case, as the externals for the Gainstrong accessory attending actual familiar.
Correcting a botheration from the ancient versions of the artefact (shipped afore Sochule acquired Anonabox), the accessory I activated uses WPA2 pre-shared key (PSK) with the Temporal Key Integrity Agreement (TKIP) and the Counter Mode Cipher Block Chaining Message Authentication Cipher Agreement (CCMP) “forced.” In added words, it’s application AES encryption for the connection, instead of no encryption as aboriginal units did. This is not the alone change to the cipher aback Anonabox went from Kickstarter to IndieGoGo, and it’s an adumbration that Germar and aggregation accept taken some of the criticism of the accessory constructively.
One affair has not changed: Anonabox has no user interface whatsoever. The alone interface the $99 device comes with is a countersign printed on a sticker; don’t lose it, because it’s your countersign forever. (The countersign is at atomic 24 characters long. I approved entering it on my iPhone 12 times afore it absolutely took.) The Wi-Fi SSID of the Anonabox activated was “Anonabox,” and like the password, it will never change. And if there’s a software botheration with Anonabox itself… well, it may be time to buy a new one.
Germar and aggregation additionally fabricated an absorbing best apropos how they configured Anonabox’s networking. Rather than application one of the absolute clandestine arrangement IP abode ranges (like 192.168.x.x or 10.x.x.x), the Anonabox uses an IP abode block allocated to Softbank in Japan (126.x.x.x). While aggregate activity out of the Anonabox passes through Tor anyway, and the accessory doesn’t abutment bounded acquisition on the LAN-side by design, there’s an alfresco adventitious this could account absorbing problems for anyone application Softbank Telecom services. Aback we attempted to ping the Anonabox from central by its aperture address, it appeared to canyon the pings through to a Softbank server tunneled through Tor. It did the aforementioned affair with a anchorage browse (sorry, Softbank).
On the additional side, the adaptation of Anonabox we accustomed was adequately able-bodied bound down. Anchorage scans showed no accessible ports from the Internet side, and it appeared to be absolutely bound bottomward from the LAN ancillary as able-bodied (though it did acknowledge to pings from the LAN side). Aback we acted like a bad user and approved to admission casework that would not avenue over Tor—specifically, things like Skype—they didn’t work. No admonition UDP cartage leaked out to accord us away to abeyant onlookers.
However, there was some UDP cartage that did leak—mostly to Google. Some Simple Account Discovery Agreement M-SEARCH multicast cartage and Quick UDP Internet Connections (QUIC) cartage slipped accomplished Anonabox’s firewall rules. The alone added non-Tor cartage advancing from the accessory was Arrangement Time Agreement requests to hosts at NTP.org.
When we asked Germar about the UDP issue, he said the firewall rules had been anchored in the latest accumulation of Anonaboxes alien afterwards this advance unit. “We accept a nightly body that food the firewall rules,” he told Ars. However, there was no way to administer the adapted firewall rules to this test Anonabox because… there’s no authoritative interface.
There accept been a cardinal of added problems baldheaded in beforehand releases of Anonabox. A column this anniversary abundant a way to accretion admission as basis to Anonabox over a defended carapace application IPv6 (and the column approved that the hard-wired basis countersign for the accessory was “admin”). That led to a anamnesis of accessories that had been shipped, and the bug was fixed, array of, in our analysis unit: IPv6 was disabled.
So what would Anonabox users do if addition above software bug or vulnerability was apparent in the device’s amount software configuration? Apparently, they’d charge to address it aback to the architect or aloof buy a new one.
The abridgement of a user interface also, ironically, creates article of an anonymity problem. If you’re application a Wi-Fi router that’s aboveboard broadcasting the SSID “Anonabox,” it’s not awfully difficult for addition to clue bottomward who’s application Tor in a specific location. Aside from that, the abridgement of an interface makes the Anonabox somewhat one-note; there’s no way to, for example, configure Tor to use a specific Tor arch or proxy.
Germar said that “the afflatus for this accessory was Arab Spring. They blocked Twitter, and our ambition was to actualize article that a accumulation of bodies can use to get aback assimilate Twitter and Facebook. That’s a band-aid for a specific blackmail model. It’s not absolutely accessible to body article that’s all things for all people.” Germar went on to say that Anonabox affairs to actualize altered accessories for added tasks. The accepted adaptation is “not a Swiss Army knife,” he admitted. “It’s meant to do one thing.”
That one affair is carrying Tor admission from locations not absolutely blocking admission to Tor relays or shutting bottomward Tor cartage by its fingerprint. So if you appetite a black-box aegis accessory that you can accord aloof about anyone in adjustment to access Tor from their home network’s router or a assignment or auberge Ethernet port, Anonabox may be an adequate advantage depending on their accident profile. However, we’d acclaim cat-and-mouse to see the third-party aegis analysis the aggregation says is actuality performed on its not-quite-open antecedent cipher to accomplish sure.
