Re: IMPORTANTE: Posible malware en Bitcoin Core oficial

En el link a virustotal.com que envías, se indica que 7 de 56 antivirus lo detectan como amenaza. El resto lo considera seguro. En mi PC con Windows Defender actualizado lo considera seguro.

Las firma de los desarrolladores de Bitcoin Core es correcta, por lo que lo más normal es que se traten de falsos positivos. Los falsos positivos son relativamente comunes cuando se utilizan las capacidades heurísticas de los antivirus, y especialmente elevados en este pequeño mundillo lleno de amenazas donde es difícil separa el trigo de la paja  Smiley



Es muy posible que sea debido a que los demas antivirus todavia no han analizado el archivo, y por eso todavia no lo detecta. Hace 4 dias solo lo detectaban 3, ahora lo detectan 7. La version de 32 bits, por el contrario, aparece como totalmente limpia.

En este caso no es un supuesto por analisis heuristico, si no algo que parece confirmado, y ya es conocido ( Trojan.MSIL.CoinStealer.km ) utilizado anteriormente para robar wallets: https://www.symantec.com/security_response/writeup.jsp?docid=2014-031707-4452-99

Ya advirtieron de que algo asi podia pasar con la version anterior: https://bitcoin.org/en/alert/2016-08-17-binary-safety

IMPORTANTE: Posible malware en Bitcoin Core oficial

Os pongo el enlace original: https://bitcointalk.org/index.php?topic=1694796.20

Al parecer despues de varios dias no tiene pinta de falso positivo... incluso kaspersky elimina el archivo. He enviado algun email a otros desarrolladores, y nada. Como veis, tampoco parecen darle mucuha importancia, no pasa nada si el cliente/web oficial de bitcoin.org esta comprometida o algun desarrollador ha introducido malware... es lo mas normal...  Roll Eyes

Todas las claves de los archivos coinciden con las oficiales, el cliente de 32 bits aparentemente esta limpio, y es el 0.13.1 de 64 bits el que lleva un supuesto regalito.

Where did you download your bitcoin core.. honestly i tried to scan and here the 2 result from their exeinstall and zip file
Exe result https://www.virustotal.com/en/url/8fea1cc9947c2a98ca0877240732c7dbcb3d1f01d6ee35d313b7b0ad6089ea5b/analysis/1480269102/
Zip file result: https://www.virustotal.com/en/url/ac4e447006b7fc4085d760427d40fcf66b5b4090ed2c51144ab9bbafab27ccdb/analysis/

This one is exe and i download it from bitcoin.org but upon scanning it in virus total there is one detected
here https://www.virustotal.com/en/file/a7d1d25bbc46b4f0fe333f7d3742c22defdba8db9ffd6056770e104085d24709/analysis/

I think it is just false scan from some anti virus just like other said.. i tried to scan it in my kaspersky but there is no virus detected..

FYI:
This is a common mistake people make when using virustotal.
the two first links you posted are not scanning any files (.zip, ...) they are instead scanning the URL you can see it from the link itself which is marked by ../url/... and reporting if the website has any malware on if when you visit.

the last link however is scanning the file because you have uploaded it. the link has ../file/... in it.
i could not find a way to not download then upload so far so if anyone has any solution i would be glad to know it. but with virustotal if you want to scan a file you have to upload it just putting the link and scanning will not scan the file.

You can click, in the upper part: File scan:   Go to downloaded file analysis

May I ask why you are running a full bitcoin node on your home computer? Doesn't it take forever to sync or are you running your computer 24/7? Thanks for supporting the network btw  Grin Grin Grin

Dedicated server, anyway, if you run a computer 24/7 it does work without problems.

I'm scanning the bitcoin-qt.exe client. Try with the one you have installed.

I think you have to have better look at this https://bitcoin.org/en/alert/2016-08-17-binary-safety

verifying your download using signatures from multiple developers using the gitian signatures repository

And also report this to bitcoin.org team.

Why? I only see 3 options here.

#1 bitcoin devs did slip malware in the code, what do you expect them to do if you tell them you found it? Confess?
#2 bitcoin devs did not slip malware in the code, its a false positive. Contacting them is useless, because they cant change the situation. Contact the anti virus vendor instead.
#3 bitcoin devs did not slio malware in the code, its not a false positive. Verifiying you are downloading the real thing solves this without contacting anyone.

The SHA256 signatures match the signatures specified by bitcoin.org. I will contact ASAP Bitcoin.org and some antivirus vendors...

Just downloaded the latest Bitcoin Core from bitcoin.org, scanned it at https://www.virustotal.com

And bingo  Undecided Angry

SHA256 from bitcoin-qt.exe 90f54d929626cbbc0fa0cdddb509feb4f11e8633b8e4d016be91673bae081338
SHA256 from the bitcoin core zip file match the right one: 3956daf2c096c4002c2c40731c96057aecd9f77a559a4bc52b409cc13d1fd3f2  bitcoin-0.13.1-win64.zip

Edit: The SHA256 match the signatures specified in the Bitcoin.org website

Link to the scanner results:

AegisLab   Uds.Dangerousobject.Multi!c   20161127
Kaspersky   Trojan.MSIL.CoinStealer.km   20161127
Rising   Trojan.CoinStealer!8.168F-c5irH5Q00gL (cloud)   20161127

Edit2: Seems like the Rising antivirus doesnt mark it anymore as a malware. Edit 2.1: Added again as malware

Edit3: I see that the 32 bits binary is totally clean in virustotal. This only happen with the 64 bits binary of bitcoin-qt.exe

Edit4: Confirmed. Kaspersky deletes the file on sight, and more antivirus marked the file as infected. Doesnt seems to be a false positive.

assuming blockchain is the same size, how does this improve the speed of the download?

I have started yesterday a new node. The full blockchain was downloaded in about 16 hours.

Ojo con breadwallet para iOS
by

on 07/02/2015, 14:12:28 UTC
Hola,

Queria informaros de un comportamiento un tanto "extraño", con la app breadwallet de iOS.

Si instalas la aplicacion, generas tu direccion BTC, despues eliminas la app y la vuelves a reinstalar... la cartera/clave privada o como sea que funciona la aplicacion, sigue ahi.

No se a vosotros, pero a mi me parece totalmente inseguro, que aun borrando la aplicacion la clave privada siga en el movil. Y que no venda el desarrollador que esta en el llavero de OS... blablabla. Que si, que el codigo fuente esta disponible... pero puede ser distinto de la version que se ofrece ya compilada desde el App Store.

Lo que yo creo que le hicieron a Ross fue que le maltratatron, lo torturaron y le amenazó a toda su familia, y por eso reveló la "contraseña" a los de Estados Unidos.
La "contraseña" es un private key, algo bastante largo y dificil de memorizar, y además, no lo puedes eligir tu mismo.

Es extraño que ningún medio haya informado nada al respecto de cómo ha podido el FBI "apropiarse" de la clave privada de los bitcoins de Silk Road.

Más extraño es todavía que a nadie parezca interesarle.

A ver, es que es obvio, todos sabemos que le amenazaron y le torturaron. Ese es el modo que el FBI hace las cosas.

Exacto, asi funciona USA. Tortura y genocidio, usaron el metodo de la llave inglesa. ¿Te gusta la llave inglesa? Pues te vamos a estar atizando con ella hasta que nos digas la contraseña. Y entre hostia va y hostia viene, unas sesiones de asfixia simulada.

Who gives a flying f*** about what the uninformed masses in the USA thinks?

Here's some more random info, and who knows, some of these claims about the stupidity of the masses might even be true!

- 25% of USAnians don't believe in Darwin's theory of evolution while less than 40% do.
- Two out of five USAnians think teachers should be able to lead prayer in the classroom, despite the fact that the separation of church and state is a foundation of their democracy.
- As of just a few years ago, about half of USAnians still suspected a connection between Saddam Hussein and the attacks of September 11th.
- Nearly one-fifth of Americans think Obama is a Muslim.
- About a decade ago, 20 percent of USAnians still believed that the sun revolves around the earth.

Veo que si quisiera, GHash no tendría ningún problema en disminuir su potencia de minado (por ejemplo subiendo sus fees).
No han dicho nada? Es que me parece muy irresponsable por su parte dejarse crecer tanto cuando a largo plazo ganarán mucho más que lo que pudieran ganar a corto.

Si que han dicho algo, aqui tienes la respuesta de este elemento:

Por qué están tardando tanto los mineros en moverse a otro pool? No sería posible que desde la directiva de GHash se limitara el poder de minado para no generar estas alarmas? Algo así como no aceptamos más mineros si pasamos del 47% de tasa de hash.

No, esta claro que la gentuza de ghash les da igual. Ya han dicho que "no le van a hacer nada al bitcoin", pero aun asi estan intentando conseguir mas del 50% a toda costa.
