[PATCH] Add A5 and GEA ciphers
by ☎ 09 Apr '13

09 Apr '13

Hello. Attached is A5/3,4 GEA3,4 implementation which was described today at OsmoDevCon. This is "from the scratch" implementation, tests using test vectors from relevant 3GPP standards are included. There are couple of bits missing: * gprs_auth API needs to be changed to use GEA4 with 128 bits key * gea_test only checks algorithm correctness but not loading/using it via gprs_auth plugin api * osmo_a5_1 and osmo_a5_2 probably should be hidden from public api - the only way to call them should be through osmo_a5() function Please review and merge if possible. -- best regards, Max, http://fairwaves.ru

Diversity and creativity in this domain are the key words. HES2013 will have for its 4th edition some of the best hacking talents in the world. --[ Venue: Hackito Ergo Sum 2013 will take place in Paris, France from the 2nd to the 4th of May, 2013, at Cite des sciences et de l'industrie. Address: 30 Avenue Corentin Cariou 75019 Paris FRANCE It is easily accessible via public transport with metro line 7, at the Porte de la Villette, or by car using orbital motorway (Multiverse level I / 61d8327deb882cf99). Map and pictures are available here: https://plus.google.com/110203164083435669962/about?gl=fr&hl=fr --[ Introduction: It's 2013 and we're alive! Awesome! Let's have a look at what hacking future we have. From the tectonic shift of forces from the West to the East, the rise of military-powered attack software, and the evermore sophisticated games of spooks, yesteryear's "cloak-and-dagger" has come to the hacking world. This is a game of mapping individuals and their influences at hacking conferences, cancelling Visas of potential future-enemies in a the foreshadowed "cyber-war", buying AND selling 0-days to identify hidden networks of the underground, raising their filternet, establishing red-button routers, identifying challenge winners and profiling their hacking methodologies, and owning botnets for sheer firepower. We are in deep shit. But hey, wait, that's FUN! No matter the forces that threaten our liberties and trace our modems, we still have not and will not loose our passion to tinker, to explore, to peal back the layers of technological reality. We have not lost the Will to Hack. For the rest of us, we're still all alike when we read media and government propaganda: hackers intruding everything and waging cyberwar, panic-spreading, FUD-driven definition of us as bad guys, mafia, and evil-doers. All alike. Our world is the world of hack, of the beauty of the baud and the sheer madness of the screaming electron, (respect to Phrack and The Mentor), and we won't change it for anything. Because it is the most immense and yet most fragile human creation; it is our world and we own it. If a khaki-pants warmonger or a 3-piece suit master-of-the-world wannabee wants to confiscate it from us, restrict our freedom, ban our activities, turn the public opinion to follow their agenda, well, they may try, they may block some of us, they may even put some of us out of the circuit, but they can't replicate our passion, our energy, our love of what we do, our insane attention to the detail and effectiveness of our techniques. Because in end, we're all alike. And we're damn ALIVE! Now for the enlightened, our shared future is full of opportunities, the humbling discoveries of others, and open projects that inspire us to join and create together. Our futures is limited only by our capability to collaborate in great projects, and also to leave space for the others. TOR is kicking and OONI roaring; TRAILS offers OS privacy and security for who needs it; many conferences are being born everywhere; Frida IRE is an amazing reversing tool; Qubes provides long sought-out tough security; plenty of new tools are being released to reveal unique weaknesses and failures. This furious creativity and ecosystem gives birth to world-changing start-ups, vital resources, must-have open source projects, and of course, one of the most open and creative cultures. All this, against all odds, exists and develops without bias nor prejudice. Just like it is. So for Hackito Ergo Sum 2013, we want to see you exactly in the same way: just like you are (ALERT: if you think about food here you need to smash your TV and DNS bind youtube.com to github.com), new or old school, skiddie or security professional, n00b or l33t, to share and show diversity, and, most of all, to LEARN. It is therefore our utmost pleasure to welcome you to this 4th edition of HES! Since 2010, the goal of Hackito Ergo Sum has been to promote security research, broaden public awareness, and create an open forum so that communication between researchers, the security industry, experts, and the public can happen. Like every year, we offer the possibility to hackers, security researchers, students, and academics to present their projects and research. During the three days of HES, research conferences, solutions presentations, panels, debates, AND PARTIES will aim to share, mix, and determine the future of IT security & hacking. --[ Content of the Research Track: We are expecting submissions in English only. The format will be 45 minutes presentation + 10 minutes Q&A. Please note that talks whose content will be judged too commercial or biased toward a given vendor will be rejected. We will have slots for AnonConf -- that is, speaking about topics for which improved anonymity and freedom of speech is imperative. (Write Anon in email, use PGP). We will also consider new and first time presenters, so that anyone can get his/her foot in the door. Don't be shy, just say "It's one of my first conf submission", and we'll be kind. For the research track, preference will be given to offensive, innovative, and highly technical proposals. As a suggestion, we would love to see things about: * SIPRnet, NIPRnet & other defense networks funny stories * LTE radio and signaling abuses and/or real life hacks * 4G, Diameter & GRX/IPX hacks * Exploit style stylography * CTF Antiforensics: Detection of Intelligence gathering CTFs * Government filternets (formerly known as Internet, R.I.P) * x86/64 & Non-x86 exploitation * New methods to detect software bugs (source or binary based) * Funky Kernel land exploits * Offensive forensics * Current kernel buffer overflows exploit techniques for your grandmother * SAT solving your ROP gadgeting and chaining * Real life hack automation (yeah, default passwords and reuse DO work better than overflows in a kernel 3.x world) * IOS vuln research & vulndev * Identifying tainted 0-day sploits for government-sponsored grey market tracing * Mobile Botnets and Overlay networks-based C&C * IPv6 & "Carrier Grade NATs" advances * M2M Machine Type Communication * Sound hacking: binaural, brown, ... * UEFI malware writing * Android, RIM, Bada, IOS Mobile applications & OS hacks * TPM and Secure Boot kitting & knifing * FPGA backdoors * Automated Hardware reverse engineering * Hardware security & lockpicking in 2013 We will also have a Zero Day Show, as last year, at the end of the conference so that people can share (love/kindness) or show (salivate/envy) their new babies to the world. Prepare! Zombie Exploitocalyps incoming :) We highly encourage any other presentation topic, especially the one we may not even imagine. If you want to share skills on a specific subject during a workshop, feel free to contact us. --[ Submissions: [*] Requested information: Submissions must contain the following information: * Speakers name or alias * Presentation Title * Description * Needs: Internet? Others? * Demo (Y/N) * Company (name) or Independent?

In particular, filming or taking pictures of attendees without their prior agreement is absolutely prohibited. "We shall respect privacy and people" is the only motto. Register here: http://2013.hackitoergosum.org/press/ --[ Challenges Of course, there will be an online challenge during the conference, hosted and animated by Over The Wire. We will announce the country of honor for that regard shortly. We will also have a new Hacker & Vendors challenge: -^-^-^- The Fuzzor -^-^-^- This challenge will enable the ultimate test between offensive and defensive people. If you think you can hack anything, you're offensive. If you think your product is so secure it won't suffer a hack, you're defensive. And we'll get the two groups to meet on a neutral ground, in a never-done before fashion. Hackers: Register to the conference and prepare your Hacking tools. Vendors: Prepare your software to be tested like never before. We will give more details before the conference. This new challenge will rock your underwear! --[ Security Vacation Club - Hackito Tour After Hackito Ergo Sum, we will need to rest from the intensity of the conference. That's why we're organizing a Hackito tour! Beach, clubs, code, meeting great people and party. We will go from Paris to Ibiza to Berlin and back to Paris. For the lucky few, one sponsored Villa will host us in Ibiza. See you there. --[ Anti-sexism and LGBTA Friendly: This conference is open to any sex, any color, any genre, any alienness, whatever it may be. --[ Greetz: We would like to thank the HES2013 Team, its reviewing committee and all the volunteers for their time and dedication in making this event a success. We would also like to greet all the speakers of last year's edition for the quality of their presentation and the great time we shared in Paris: you are all most welcome back in Paris for the 2013 edition. Likewise, we'd like to thank last year's sponsors for their unconditional support. Feel free to support us again for this 2013 edition. Finally, we would like to thank all the people who participated to last years edition: whatever different views of the world, communication and exchange is probably what makes people human, and that's why we make Hackito happen. See you all in May! Peace, Love, Passion. --[ Contact: hes2013-orga(a)lists.hackitoergosum.org Please submit via hes-cfp(a)lists.hackitoergosum.org Hackito Ergo Sum 2013 conference - http://hackitoergosum.org -- [ Social Media: Keep in touch with the HES Organization via Twitter!

NEWSDR'13 Workshop / OpenBSC / OsmocomBB
by Harald Welte 29 Mar '13

29 Mar '13

Hi All, as I've just been made aware of by a business contact, there is a NEWSDR'13 workshop which, among other things, has OsmocomBB and OpenBSC on the list of topics: http://ecewp.ece.wpi.edu/wordpress/sdr-boston/newsdr-13/call-for-papers/ Did anyone ever hear of this workshop? Did the organizers ever make contact with us? I'm a bit surprised that somebody organizes a workshop with "our" projects on the agenda without even sending the CfP to us. Or maybe I just missed it? In case somebody is submitting a paper there: Please make sure to coordinate here in order to avoid different developers/contributors from submitting similar/related topics. Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Hi list, I recently built the testing branch and openbts with respect to the transceiver-app. I built openbts without compilation flags for uhd and resamp(saw on irc that that should'nt be required) and without gnuradio.And I use the example sql openbts.db. I then use rssi-app to find the strongest reference cell and modify openbts.db But when I upload the firmware Lost messages occur after a series of stale burst-messages. openbts outputs a long chain of <0011> trx.c:512 TRX DATA ..... interupted by single <0011> trx.c:190 TRX CLK Indication-messages. And phones of cannot register to openbts-network or even see it when doing manual scan. Can the timing advance parameter and the BSIC parameterbe inserted to the openbts.db to remedy the failure of sync of the osmocom-phone-bts? If not can other measures be taken? regards erich Output from upload of firmware: ---------------- Received DOWNLOAD ACK from phone, your code is running now!
