Summary
OUR E-GOLD ACCOUNT: XXXXXXX
INSTRUCTIONS HOW TO GET YUOR FILES BACK
READ CAREFULLY. IF YOU DO NOT UNDERSTAND, READ AGAIN.
This is automated report generated by auto archiving software.
Your computer catched our software while browsing illigal porn
pages, all your documents, text files, databases was archived
with long enought password.
You can not guess the password for your archived files - password
lenght is more then 10 symbols that makes all password recovery
programs fail to bruteforce it (guess password by trying all
possible combinations).
Do not try to search for a program what encrypted your information - it
is simply do not exists in your hard disk anymore.
If you really care about documents and information in encrypted files
you can pay using electonic currency $300.
Reporting to police about a case will not help you, they do not know
password. Reporting somewhere about our e-gold account will not help
you to restore files. This is your only way to get yours files back.
------------------------------
How to pay to get your information back.
1. click on this link to open your free e-gold account - the first
screen is the e-gold "terms and conditions" page. You need to
agree to these by clicking on the "I AGREE" button on the bottom
on the page.
2. On the next page is the sign up form:
1. "Account name" - here is where you name your account - tip:
make it easy to remember (as you will be asked for it) and
reasonably short, example, "John's e-gold", "My Money e-gold"
or perhaps "Felix" (whatever you like, just make it easy for
you to remember it).
2. "User Name" - here just repeat the account name (from 1 above).
3. "Point of Contact" - this is where you put our name, address,
phone number and email address (any email address can be used
here but it is recommended you use your ISP address - not a
free hotmail, etc address).
It is also recommended your also include a fax number
(don't have a fax number? This company offers free fax to email
services). Try and make it as easy as possible for e-gold to contact
you.
4. "Passphrase" - this is the most important piece of information
connected to any e-gold account. We can not stress enough how
important it is that your passphrase is kept safe and secure.
5. "Turing Number Entry" - type the 6 numbers you see there into the
input
box below.
6. The last step click "Open"
On the next page it will tell you that your e-gold account number has been
emailed to you.
check your email - you can expect to wait up to 5 minutes for your account
number
to arrive. If it does not arrive after 5 minutes then that means the email
address
you supplied was incorrect and you will have to open another new account (go
through
and repeat what you just did above again).

At the top of the AUTO_ZIP_REPORT.TXT file, the number of an E-Gold account is inserted. This number is picked at random from a list embedded in the DLL. By operating many accounts simultaneously, the trojan author is betting that even if E-Gold shuts down some of the accounts, he/she will still receive payment on some of the others. The complete list of E-Gold accounts is:
The text of the AUTO_ZIP_REPORT.TXT file is encrypted inside the Cryzip DLL, using simple XOR (0x13) encoding. The
password used to zip the files is also embedded inside the DLL but it is not encrypted - instead, the author decided to hide the password in plain
sight, so to speak. The password is:
