Thing is, having seen the possibilities, people actually *want* this freedom from central control, in a bad way, and they're willing to act to get it. They also realize that if they, and the entire community, don't act together to maintain the decentralization they have... then it's over. That's why ghash.io (the largest pool) just announced that they will not exceed 40%. Down from 55% to 32% now... http://www.coindesk.com/ghash-commits-40-hashrate-cap-bitcoin-mining-summit/ http://www.coindesk.com/bitcoin-mining-detente-ghash-io-51-issue/ http://blockchain.info/pools And why BTC isn't exactly rushing to support regulation... http://www.reddit.com/r/IAmA/comments/1ygcil/as_requested_im_ben_lawsky_sup… http://www.reddit.com/r/Bitcoin/comments/2aycxs/hi_this_is_ben_lawsky_at_ny… http://www.reddit.com/r/Bitcoin/comments/2b1jpl/dear_ben_lawsky_thank_you_f… Further, again, since people want decentral, if some large entity does manage a BTC takeover, no problem... all users ok with that will stay with the now central coin, and the free decentral people will just exchange their coin (or fork) into whatever is the current decentral coin. Repeat as needed. So far BTC has a good history of actively cooperating to avoiding central. Excepting mining companies (ie: the 10% corps, who have made similar self limiting statements), the VC money seems to stay out of the coin itself and is being placed in surrounding service ventures... exchanges, banking, processors, wallets, retail. In the end years from now, maybe only three coin will remain... - A World central - A State central - A World decentral/anon/etc With all of them being roughly similar in acceptance, volatility, etc. > There also remain long term questions about the technical viability of > Bitcoin, most notably whether people will still find it interesting > after the transaction cost rises. (If a transaction costs a dollar, > there's a lot of other options with much less price volatility.) People spend more than a dollar to post mail, or drive to the store. It will be a long time before the ASIC and electric cost to clear a transaction (at whatever network transaction demand rate) exceeds palatability, if ever. Pick a projected compute power, node count, required tx rate (at 100% utilization) and then basically figure gigawatt and gigahash dollars per tx. http://www.coinometrics.com/bitcoin/btix https://bitmaintech.com/productDetail.htm?pid=00020140704023505485N5SxDMkW0… https://medium.com/@interdome/how-much-electricity-does-bitcoin-use-c350bd8… http://organofcorti.blogspot.nl/ A guesstimate with current state and data? - Installing double current hashrate to take 50+% costs about $130M in retail hardware alone. Less for a real deployment. - About $10k/hr to power it. More for cooling, support, bandwidth. - About $0.40/tx-current spread over a year. Much less if running at 100% tx rate capacity. Up to twice more due to doubling current hashrate. Right now that amount is being covered by coin mining profit. The future taper of coin production vs then current market value of coin vs tx fees will be interesting. And ASIC platforms have yet to reach performance plateau. The base tx cost is cost of the coin algorithm to support a given required tx rate. That seems quite low. The race (difficulty) to claim the tx fee profit drives it up. Yet the hardware market is open, yielding a level playing field. So as long as the required tx rate can be met affordably within the algorithm, this is unlikely to be an issue. Cost of tx rates also naturally moderate the proportion of users amongst each payment system. It remains to be seen, once all the various BTC costs are fully optimized, if BTC can handle tx rates approaching the credit cards. Even if not, that doesn't keep it from utility at its own natural rate limit. Some seriously big players don't seem to have any problem with BTC... http://www.coindesk.com/computer-giant-dell-now-accepts-bitcoin/ > To me Bitcoin is very interesting as an experiment.

Identifying back doors, attack points, and surveillance mechanisms in iOS devices
by coderman 20 Jul '14

20 Jul '14

doubt this will surprise anyone; iOS intentionally designed to support surveillance. --- http://www.sciencedirect.com/science/article/pii/S1742287614000036 "Identifying back doors, attack points, and surveillance mechanisms in iOS devices" by Jonathan Zdziarski Abstract The iOS operating system has long been a subject of interest among the forensics and law enforcement communities. With a large base of interest among consumers, it has become the target of many hackers and criminals alike, with many celebrity thefts (For example, the recent article “How did Scarlett Johansson's phone get hacked?”) of data raising awareness to personal privacy. Recent revelations (Privacy scandal: NSA can spy on smart phone data, 2013 and How the NSA spies on smartphones including the BlackBerry) exposed the use (or abuse) of operating system features in the surveillance of targeted individuals by the National Security Agency (NSA), of whom some subjects appear to be American citizens. This paper identifies the most probable techniques that were used, based on the descriptions provided by the media, and today's possible techniques that could be exploited in the future, based on what may be back doors, bypass switches, general weaknesses, or surveillance mechanisms intended for enterprise use in current release versions of iOS. More importantly, I will identify several services and mechanisms that can be abused by a government agency or malicious party to extract intelligence on a subject, including services that may in fact be back doors introduced by the manufacturer...

minimum viable toolset for low level malware forensics [was: BadBIOS forensics]

(stealth at bus/bios level). discrepancies in blocks that should not have changed, executable code segments where not expected, strange carvings of wear leveling around "protected" offsets. all of these are indicators for further scrutiny and instruction level reversing (if corresponding to microcontroller programming instructions for manipulating streams read or written to and from device, for example :) last but not least, you are not getting attached to any hardware, because at any moment you may find it all suspect and have to replace all laptops, desktops, routers, printers, mobile devices, storage media, media servers, smart televisions, and god forbid you installed one of those intelligent thermostats.

Re: Strong Security Processes Require Strong Privacy Protections, Re: [liberationtech] Foxacid payload

On two related threads: It's a challenge to work counter-spying without access to all of Snowden's alleged, note alleged -- nobody knows except Ed how many or where multiply-accumulated and -stashed from 2008-2013 and afterwards -- documents. But parsing the unknown, imagining and acting on possibilities, is the purpose counter-spying as well as spying. Failure expected, narrowing it for modest utility, no lasting triumph. Privacy as elusive as security. It could be, has been, argued that open source coding, like the Internet, is a ploy, or decoy, like comsec standards committees and spy oversight committees, even, some claim, Tor and PKC, AV and Blacknet, so forth and so on paraded here for Internet dog years. Duplicity, buyer beware and who watches the watchers inherent, is that not the wee chihuahua way of survival against greater powers of Fort Huachuca whisperers, GMO vegetables, fracked minerals, DoD-fabricated asteroids and black hos of nightsweat zombies. Whistling in the dark, whistleblowing sunshine, coding out of sight except for sneaky supra-Tempest io-germs gnawing backbone taps into HUMINT dervishing switch doctors.

Some, maybe all, of those sitting on Snowden docs would/are selling to the highest bidder for other clandestine hacks. The fundamental purpose of security is to do that lulling, gulling and smiling at the ease with which trust can be exploited when a manufactured crisis drives the fearful into gaping maws of protection. The especially private kind, the higher the secrecy the higher the price, is most effective. Fake highest classification markings obligatory. The frenzy to exploit Snowden revelations, tiny as they are, has saved the security industry -- mil-com-spy-edu-org-hackers -- from post-2-war decline. BTW, what are the odds all parties to the Snowden boondoggle are placing on hot war cyberwar to surpass the cool stinking-poo of AV and security vendors planting malware to foster upticks of market? No nonsense Omidyar has bet $200 million on peddling security products generated by his $50 million investment in insecurity scare news via Snowden cornicopia of NSA scare programs, which in turn have received huge boosts of counter-Snowden actions by the usual suspects of mil-com-spy-edu-org-hackers. Nothing like it since 9/11. Thank you, Edward Snowden, thank you media, for prolonging godsent cyber fear and salvation. Dust off cyber Pearl Harbor posters for Defcon, HOPE, Blackhat, this very sordid squat. >this is exactly why some who have received these payloads are sitting >on them, rather than disclosing. > >it is more useful to mitigate privately, and observe how/when an >exploit is used, > than burn it publicly for zero effective security improvement. > >(the less scrupulous would sell to highest bidder for other clandestine hacks) > > >better ideas welcome! > > >best regards, >-- >Liberationtech is public & archives are searchable on Google. >Violations of list guidelines will get you moderated: >https://mailman.stanford.edu/mailman/listinfo/liberationtech. >Unsubscribe, change to digest, or change password by emailing >moderator at companys(a)stanford.edu.
