Need help with a virus tales-from-the-crypt 2.0 - Msieve - Page 5

Ok. Did YAFU find any factors before that? Also, did you follow all of the steps in the post "Teslacrypt 2.0 Factoring"? There are some more files for you to download.

Download the files from here: http://www.mersenneforum.org/showpos...5&postcount=16 and put them in your GGNFS directory. That should fix the error.

GGNFS_PATH = 'D:/programme/faktorisierung/lasieve4_win/lasieve4_westmere/'
MSIEVE_PATH = 'D:/programme/faktorisierung/msieve/'

Regards Andi_HB

Based on the error he's getting, I'm pretty sure he's got it right. There was a fix to the GGNFS binaries to change how it handled some inputs that I forgot to account for.

Hi Andi,

I have not used GGNFS here, i have just used YAFU

yafu-Win32.exe factor(0x113126C6F0EF0F0CB2AD384303AEAF20019E8C22C157CE5A4E27342A5C0FAED46FE21CA08BD44F7C2A829053993D5514DBE169A56F67E8D31D8D6E73BCF51608) -v -threads 4

Hi Wombatman,

I downloaded the files and placed in the same directory and now ended up with different error this time.

How much are you guys willing to donate to a charity to get the factors of your numbers?

wombatman · 2015-12-31, 18:55

http://factordb.com/index.php?id=1100000000811434013 is fully factored.

Nizam, what does this line in yafu.ini say?

Code:

ggnfs_dir=

You need to change this line to match where you put the GGNFS executables (the ones that start "gnfs-lasieve" with different numbers at the end). If you followed the directions in my how-to post, it would have been C:\GGNFS\.

Googulator · 2015-12-31, 19:02

I'm now struggling with this key:
http://factordb.com/index.php?query=...61887858943865

That C134 appears to be a semiprime; ECM finds nothing in it. When I try to factor it with either GGNFS or YAFU, my computer spontaneously reboots after a few minutes of sieving - same computer that I previously used for successfully factoring a C154 semiprime.

EDIT: This is from an older version of TeslaCrypt, which uses only one key (no distinct Bitcoin and AES keys).

hlopezdp · 2015-12-31, 19:07

I received a computer with all the files encrypted, so I managed to search and get here.

With teslacrack I got this public keys:

Quote:

Software has encountered the following unknown AES keys, please crack them first using msieve:
02C4222BB23D858714A127034ACE67B2FA4E5A0B7ACF2B44A4DA71FA2867D5AF31C5D563D8EFC9D98C3D9FAD65D917F2179386BADAAF33BC6466FDB8B06741B3 found in ./SAM_3558.JPG.vvv
Alternatively, you can crack the following Bitcoin key(s) using msieve, and use them with TeslaDecoder:
03D8DB0E7827DD53F39B5F44C82F9E8AE08577135D7D5229D49981A487AE9D16EA6F6B7623A1073F7E667C87CF6EDCDF169B8763B9ADAF51D9CE7A4545EB7443 found in ./SAM_3558.JPG.vvv

The first one is taking a lot to being factorized. I'm using an AWS instance (8 vCPU, 15 GB RAM, 1 CUDA GPU) to do this. Just got same factors available in factordb => http://www.factordb.com/index.php?id...00000811949725

The Bitcoin key case is different, got factorized in some minutes:

Code:

***factors found***

P1 = 5
P1 = 5
P2 = 11
P2 = 41
P3 = 307
P4 = 1493
P4 = 2671
P5 = 24029
P6 = 145501
P6 = 223757
P33 = 759082218747625708092549791381327
P37 = 3927181788575019346095440315675297017
P55 = 6259126025771703397105968073316207537733930113978073731

And got the Bitcoin key with unfactor-ecdsa:

Code:

Found Bitcoin private key: 3694D0A885FD65C74FCEC6FF68F4EB12DD7A654E8896288BF76A4A00BD7BD05B

But at the moment of trying to decrypt file with TeslaDecoder, it just crashes.

Any ideas?

(Thanks to everybody !)

You need to convert the hexadecimal number to a decimal number. Put

Code:
