1  Local / Biete / Ingress passcodes (keine invites) per SMS on: January 27, 2013, 04:02:31 PM
Hi,

hat jemand Interesse daran Ingress passcodes, sobald sie öffentlich bekannt werden, per SMS aufs Handy zu bekommen? Ich hab das System jetzt ein paar Tage getestet und konnte alle passcodes rechtzeitig einlösen, aber man muss natürlich sehr schnell sein und sobald die SMS kommt den code sofort bei ingress copy&pasten.

Die Anzahl der freien Plätze ist begrenzt und das Angebot beschränkt sich im Moment auf Handynummer aus Deutschland, Österreich und Schweiz (andere Nummern sind aber evtl. möglich, bitte per PM anfragen).
Preis wäre 1 BTC für eine Woche passcodes (SMS kosten inkl.).
Falls ich aus technischen oder sonstigen Gründen die Verfügbarkeit des Systems nicht garantieren kann (unwahrscheinlich) erhält natürlich jeder Anteilig seine BTC zurück.

Der ersten Person die sich meldet würd ich mal einen vergünstigten Testtag anbieten.

Bzgl. dem Datenschutz:
Sämtliche Handynummern werden ausschließlich zum SMS versenden benutzt und nicht weiter gegeben. Sie befinden sich auf einem vollständig verschlüsselten Dateisystem auf einer Linux Kiste und werden nach Ablauf der Woche gelöscht.

2  Bitcoin / Mining software (miners) / RG7Miner - Icarus FPGA board miner on: February 23, 2012, 09:28:34 PM
Just released my java miner for the Icarus FPGA board (see https://bitcointalk.org/index.php?topic=51371.0).

Features: If you have a Icarus board, it'll mine bitcoins for you Grin. This and long polling.

This is the first thing I release as open source, so feedback is highly welcome Smiley. The miner should run on win, linux and mac.

Download: https://sourceforge.net/projects/rg7miner/

2012-02-25: Uploaded v0.1.3 which fixes various bugs. Updating highly recommended.
3  Bitcoin / Bitcoin Discussion / Possible hacking targets on: June 21, 2011, 10:05:03 PM
Hey guys, watching this recent hacking activity, I thought about what might be attacked next. What I think might be very sensitive points to attack are the pools and the miners itself.

Were the pools and miners programmed with strong security in mind? Can pools/miners defend to all crap of invalid input and other attacks? If attackers could successfully run some buffer overflow attack (for example) on a pool, they could 1. do lots of malicious stuff with the pool itself (steal coins, fuck up with transactions, try to fork blockchain if pool is big enough) and 2. start attacking the miners itself and steal their wallet's coins if successful (assuming they're on the some machine - many will). I don't know, can python / java programms (miners) somehow get exploited with stuff like buffer overflows like it's done with c(++) programms?

Of course an attack like this might require more skills than to use a trojan to steal the mtgox db (if that actually happend) and suck the accounts with weak passwords dry, but it's a risk we should mitigate better now than later.
And, well, I see slushs pool using csrf protection (Smiley) bit still no ssl (yes you can use https and ignore the warning but the account credentials will get submitted WITHOUT using ssl). btcmine is using ssl but has no csrf protection (at least not when I checked it the last time). That two pools are the only I used so far. Don't misunderstand me, I don't want to run down on the pool ops, I'm basically quite happy with the pools, but this simply doesn't give me much confidence that the described attack won't happen some day.

Please, pool operators and miner coding guys, check your codes for security aspects, treat every user input as evil and run it against a whitelist, maybe even consider implementing a solid security toolkit as owasp esapi https://www.owasp.org/index.php/ESAPI (not intended as a commercial but I use it for my own projects and I'm quite happy with it).

I think it's important to have this things as fkn secure as possible. OK maybe I'm just paranoid, but I didn't get any coins stolen (yet?  Roll Eyes), being paranoid is great Grin.

What do you think?
4  Local / Biete / Gutschein für lovefilm.de zu versteigern on: May 24, 2011, 06:06:21 PM
Hi Leute,

ich hab noch nen Gutschein für lovefilm.de den ich hier gern versteigern würde. Eigentlich gehört sowas ja ins Marketplace-Subforum aber da man ne deutsche Anschrift benötigt um den Gutschein nutzen zu können ist das Angebot hier wahrscheinlich besser aufgehoben.

Zum Gutschein:

60 Tage gratis Filme leihen (die normalen Probeabos laufen wenn ich mich jetzt nicht täusche 14 Tage).
Der Gutscheincode kann ZWEI MAL verwendet werden (allerdings nicht vom gleichen Kunde) und ist bis Ende 2011 gültig.
Wenn man nicht rechtzeitig kündigt wird man nach Ablauf des Probeabos zahlender Kunde, also bitte dran denken wenn man nicht vor hat das Abo weiter zu nutzen!
Seite zum einlösen: http://bit.ly/kqr11d (lovefilm.de/vorteil)
Startgebot: 1 BTC

Viel Spaß beim bieten  Grin
5  Bitcoin / Bitcoin Technical Support / Limit RPC access to getwork cmd? on: May 11, 2011, 05:38:33 PM
Hi,

is it possible to only allow getwork and deny all other commands?
Or what would be a good way to connect multiple miners to one bitcoin instance if the miners can't be trusted?
6  Economy / Marketplace / Experiences about doubletrouble.bitcoinbet.com? on: February 25, 2011, 12:00:29 PM
Has someone experience with doubletrouble.bitcoinbet.com?
I played 9 games, won the first and then lost 8 times in a row.
The propability for losing 8 times in a row is 0,51^8 = about 0,46%. This brings me to the question if I'm just really really unlucky or if it's a scam.

Maybe some people who gambled there can report if they also were that unlucky or if their luck followed the statistics better.
