Jailbreak firmware turns cheap digital walkie-talkie into DMR scanning receiver

- joezydeco 11y agoI'm instantly in love with the International Journal of PoC||GTFO. How did I not know about this before? It feels like the old Apple ][ hack/phreak days again. http://www.sultanik.com/pocorgtfo/ http://www.sultanik.com/pocorgtfo/
- toomuchtodo 11y agoTakes me back to 2600 :)
- joezydeco 11y agoI thought 2600 too but 2600 was, IMO, light on the PoC and very heavy on the GFTO.
- unimpressive 11y agoOn that note, this is one of the most impressive demos I've ever seen: https://www.youtube.com/watch?v=04Wk9Oi_Fsk https://www.youtube.com/watch?v=04Wk9Oi_Fsk (When you're familiar with what a baseline atari 2600 game looks like, this is just beyond the pale.)
- nfd 11y agoStill is heavy on the GTFO, they still know how to tell tell people to fuck off in innovative and superficially polite ways.
- mutagen 11y agoOK I'm in love too now: >>Technical Note: The polyglot file pocorgtfo10.pdf is valid as a PDF, as a ZIP file, and as an LSMV recording of a Tool Assisted Speedrun (TAS) that exploits Pok´emon Red in a Super GameBoy on a Super NES. The result of the exploit is a chat room that plays the text of PoCkGTFO 10:3. Run it in LSNES with the Gambatte plugin, the Japanese version of the Super Game Boy ROM and the USA/Europe version of Pok´emon Red.
- semi-extrinsic 11y agoThen there's the articles by Natalie Silvanovich, who's specialised in hacking different versions of Tamagotchis. I mean... they're Tamagotchis, for crying out loud. A tiny plastic box with a 16x32 pixel monochrome screen, a speaker and three buttons. But this awesome hacker goes out of her way to pwn that 6502 and run her own code on it...
- morcheeba 11y agoYou've got to see her CCC video! https://media.ccc.de/v/29c3-5088-en-many_tamagotchis_were_harmed_in_the_making_of_this_presentation_h264 https://media.ccc.de/v/29c3-5088-en-many_tamagotchis_were_ha...
- SchizoDuckie 11y agoI've only found out about it a couple of weeks ago too via some infosec dudes i follow on twitter. It's hugely technical and full of awesome shit and easter eggs like the microdots in this version.
- CamperBob2 11y agoYeah, I had shit to do today. :( Thanks.
- roddux 11y agoI'm pretty sure that PoC||GTFO is the successor to Phrack (at least in spirit). They list pastor@phrack.org as the submissions address.
- DrScump 11y agoWhy did new issues stop last June?
- tomtoise 11y agoBecause that's just a mirror, someone obviously stopped updating it. Here you go :) https://www.alchemistowl.org/pocorgtfo/ https://www.alchemistowl.org/pocorgtfo/
- jdalgetty 11y agoSo does this mean you could listen to police/fire radio and such like back in the old days?
- runjake 11y agoDepends on the city/county. Most in the US are on P25, which has been listenable by clued members of the populace, but many (most?) are now encrypting traffic (usually w/ AES, iirc).
- jlgaddis 11y agoUnencrypted transmissions are easily received by scanners (note, though, that older scanners can't pick up P25) -- they aren't cheap, though (I think mine was ~$450 USD). In my area, one local police department is the only agency that has chosen to encrypt their communications. It is, supposedly, also possible to pick up P25 using RTL-SDRs, though I've never tried so I can't say for certain.
- viraptor 11y agoIf the wikipedia information is right (6.25kHz signal at ~700MHz), then it should be trivial on RTL-SDR. Just need the right antenna.
- nosy_russian 11y agoI wonder what they use in Russia? Cursory look [1] suggests it's the old analogue standard. Does it mean CB? Is there a public list of which protocols the police use, by country? [1] https://habrahabr.ru/post/145973/ https://habrahabr.ru/post/145973/
- throwaway_xx9 11y agoWhen police use encrypted radio channels, they can't interoperate with EMS, other agencies or in disaster zones. So becomes a problem.
- throwaway7767 11y ago> When police use encrypted radio channels, they can't interoperate with EMS, other agencies or in disaster zones. So becomes a problem. Depends on the system. TETRA (used in europe) can be optionally encrypted, so the police can have radios with encryption for their talk groups, but still do unencrypted communications with the medical or fire services. Around here, they run it with encryption off though, because apparently the key management is a pain in the ass and I guess the criminals they mostly interact with aren't the types to sit around with RTL-SDR dongles capturing their voice comms.
- mitchtbaum 11y agoWhat might potentially come from this ground-level work? How wide ranging could hacks for this radio support custom software, custom audio and data encoding/decoding, custom modulation, etc etc?
