    IMterview With Bluetooth Hacking Flexilis's John Hering



    We pinged Flexilis's John Hering [second from the left], part of the team behind the world record-setting Bluetooth connection (and exploit) and creators of the BlueSnipe rifle. John talked about the still-lingering weaknesses in most current Bluetooth-enabled phones, plans Flexilis has in the future to help cell phone manufacturers lock down their security, and how many video game industry executives' phones you can scan at E3 in just 90 minutes.

    One thing John asked me to make clear, though, and I thought I'd do it up front. None of these tests have involved hacking into any phones that weren't authorized by the participants. The record-setting Bluesnarf attack was done with one of their own phones, for instance. But just because they didn't doesn't mean they couldn't. Lucky for us they're trying to play by the rules and help the Bluetooth community batten down its hatches.

    It's runs a little long, but I added magical color codes to make it easier on the eyes. Read on inside.

    Gizmodo: so what are you guys doing at flexilis, exactly, that makes building hacking rifles part of your business?
    John Hering: we are a wireless research and development firm working primarily with bluetooth and wifi
    John Hering: the bluesniper was a good way to really get peoples attention, the equipment that was the functional part of the rifle was what was the key
    Gizmodo: did anyone freak out when they saw you sniping?
    John Hering: we weren't using the bluesniper
    John Hering: we actually did the link from the santa monica pier
    John Hering: to a hill 1.08 miles away
    Gizmodo: oh, well, wait, do-over
    John Hering: there is a police substation right there
    John Hering: so.
    Gizmodo: i still have bluesniper on my mind
    John Hering: the bluesniper was used at defcon
    John Hering: [for the record breaking shot] we used a 19dbi panel antenna
    Gizmodo: b/c i just watched that tom's video [This Video - ed]
    John Hering: and mind you, we were able to connect to a Class 3 device from 1.08 miles
    John Hering: a standard nokia 6310i
    Gizmodo: so when wired says 1.1 miles they mean 1.08?
    John Hering: yes
    John Hering: i hate it when people get the facts wrong
    John Hering: thats why i emailed you.
    Gizmodo: i bet wired is getting paid links from the 1.1mi consortium
    John Hering: lol
    John Hering: typically manufacturers discounted the bluetooth attacks
    John Hering: snarfing, jacking, bugging
    John Hering: because they said that the ranges were short
    Gizmodo: and you're proving that it's not
    John Hering: we have completely destroyed that notion
    John Hering: not only were we able to establish a link from 1.08 miles
    John Hering: we were able to attack the phone too
    John Hering: ripped the entire contact list, and sent sms messages
    John Hering: full snarf attack
    Gizmodo: i presume the phone wasn't pre-softened for the test, either
    John Hering: not at all
    John Hering: on the first world record attempt
    John Hering: if you heard about it
    John Hering: last week before defcon
    John Hering: we pre-softened it
    John Hering: and hit .5 miles
    John Hering: this attempt was MUCH more significant
    Gizmodo: have you heard anything from the phone companies, officially or otherwise?
    John Hering: since this test no, but we have contacted most major manufacturers
    John Hering: i know martin has contacted them as well
    John Hering: martin herfurt, who discovered bluebugging, was in from germany
    John Hering: we had a pretty tight crew
    John Hering: there is a select group of people working to fix the inherent vulnerabilities of bluetooth
    Gizmodo: i know that nokia and sony ericsson and everybody has basically said their new firmware fixes most of the exploits
    Gizmodo:have you guys found that to be the case?
    John Hering: i know that isnt so
    John Hering: nokia did release an announcement of a fix BUT
    John Hering: you must take your phone into a store and get the the firmware flashed to get it fixed
    John Hering: most consumers are clueless
    John Hering: and sonyerricson
    John Hering: i believe that their phones are still vulnerable as well
    Gizmodo: well yeah, but are the flashed phones safe from the current exploits?
    John Hering: the snarf attack yes
    John Hering: tests have shown that the bluebug attack may still work though
    John Hering: we are working on a full release as well as a white paper
    John Hering: hopefully the manufacturers will pay close attention
    John Hering: i know martin is also working on a java api
    John Hering: for symbian phones
    John Hering: you can now snarf from a phone to a phone!
    John Hering: don't need a linux box anymore
    Gizmodo: that's brilliant
    Gizmodo: if, you know, awful
    John Hering: we are doing this for the good of the industry
    Gizmodo: you're certainly being up front about it
    Gizmodo: building a rifle and all
    John Hering: we in no way want this information to fall into the wrong hands
    Gizmodo: yeah, have you released the exploits or your code?
    John Hering: of course not
    John Hering: we are release a security vulnerability assesment tool
    John Hering: which identifies vulnerable phones
    John Hering: we showed it off in the toms video
    John Hering: if you saw
    Gizmodo: yeah, you're going to release that?
    John Hering: yes
    Gizmodo: throw in an OSX version so I don't have to use this stupid dongle
    John Hering: ill definitely keep you posted, we have some amazing software
    John Hering: we are working on integrating location tracking too
    John Hering: and other bluetooth tools
    Gizmodo: yeah, definitely v. v. interested
    Gizmodo: but first
    Gizmodo: you have to let me ask about the rifle
    John Hering: of course
    Gizmodo: you can't build something like that without expecting a little attention
    Gizmodo: is the antenna you used for your distance record a yagi, too?
    John Hering: i think that was the point, people discounted bluetooth exploits, we found a way that not only displayed using the technology in a way it had never been pushed, but also we were able to attract attention to the manufacturers as our goal is to fix the inherent vulnerabilities within the bluetooth stack
    John Hering: the yagi is what we used for the first distance record
    John Hering: the 0.5 miles
    John Hering: we used a few different types
    John Hering: vwe used a different 19dbi panel antenna for the 1.08 miles though
    Gizmodo: were you shooting over the ocean?
    John Hering: no
    John Hering: beach
    Gizmodo: or from the pier to somewhere on land?
    John Hering: yes
    Gizmodo: ah
    John Hering: we were a bit worried about the moisture in the air
    Gizmodo: bluesurfing
    John Hering: LOL
    John Hering: you wouldnt believe how far away it was
    John Hering: we couldnt even see martin and mike on the hill
    Gizmodo: i bet it was over a mile!
    Gizmodo: so are you going to make an attempt?
    Gizmodo: to beat the record?
    Gizmodo: or have you proven your point?
    John Hering: we still have a few cards up our sleeves
    John Hering: bluetooth is an amazing technology
    John Hering: we are going to push it in new directions
    Gizmodo: are you guys incorporated yet?
    John Hering: in the process
    Gizmodo: cool
    Gizmodo: get a lawyer
    John Hering: definitely
    Gizmodo: so like i was asking before, but at the wrong time
    Gizmodo: did anybody see you sniping them when you were doing that tom's video (or whenever)?
    John Hering: well, we were misquoted in the wired article
    John Hering: we simply scanned
    John Hering: never actually snarfed
    John Hering: at defcon
    John Hering: that would be illegaal
    John Hering: when we attack its on our own phones
    John Hering: in a closed testing enviornment
    Gizmodo: well, i just mean people freaking out that there was some kid with a weird gun
    John Hering: but, no, people had no clue we were scanning their phones for vulnerabilities
    John Hering: people at defcon thought it was cool
    John Hering: but defcon isnt your average place
    Gizmodo: thank god
    John Hering: most definitely
    John Hering: we had it in a case too
    John Hering: i think what the bluesniper was proof of concept more than anything
    John Hering: if someone were to build a similar device into a briefcase
    John Hering: it could be taken anywhere
    Gizmodo: sure, it's mostly just a useful form factor
    John Hering: definitely
    Gizmodo: well let us know when you release the software
    Gizmodo: i'm sure lots of script kiddies such as myself would get a kick out of scanning
    Gizmodo: "look who i could own if i actually knew how to write code!"
    John Hering: haha definitely
    John Hering: i bet you would be intersted in this
    John Hering: we did a proof of concept at e3
    John Hering: 700 vulnerable phones
    John Hering: and thats where the industry's top people are
    Gizmodo: over how many hours?
    John Hering: 90 minutes
    Gizmodo: you could have assembled the best video game industry address book ever
    John Hering: i know.
    John Hering: we walked up to the nokia booth
    John Hering: and showed them all the execs phones
    Gizmodo: we could have prank called john carmack!
    John Hering: the went bonkers
    Gizmodo: i bet
    John Hering: they know there is a problem
