The desktop screen ins changes to display the ransom note. Here are the contents of one ransomware sample:

Support e-mail: [email protected] [email protected]

Your personal files encryption produced on this computer: photos, videos, documents, etc.
Encryption was produced using a unique public key RSA-2048 generated for this computer.

To decrypt files you need to obtain the private key.

The single copy of the private key, which will allow to decrypt the files,
located on a secret server on the Internet; the server will destroy the key after 120 hours.

After that nobody and never will be able to restore files.

To obtain the private key for this computer, you need pay 2.05 Bitcoin (~1309 USD)

[email protected] Ransomware Distribution

The [email protected] ransomware is distributed mainly via spam email campaigns. The messages contain infected binary attachments and links to malicious sites that host the threat. In many cases the criminals may even modify the email header information to impersonate legitimate sources like shipping companies (such as DHL and FedEx) and other commonly used services.

The attackers may use various social engineering tricks like using failed delivery notification messages and other means to make the user open the infected files.

In some of the recent campaigns the ransomware have used spam emails that pose as fax messages using subjects like “PLEASE READ YOUR FAX T6931”. The contents of the email contain a file named “Criminal case against you” which is used to gain the attention of the targets.

The emails have an attached RAR archive file that contains a WSF file. When the user downloads and opens the archive, the WSD gets executed. Inside there is a JScript function that starts a sequence of operations that downloads and installs the Crimace Trojan. This is used to download the [email protected] ransomware payload and possibly other viruses as well.

In any case the infections can be prevented and mitigated by running efficient and capable anti-virus and anti-spyware solutions. If you are the victim of a [email protected] ransomware then continue reading to restore your files from the infection.
