The "Blank Slate" malspam campaign has switched from distributing the Aleta BTCware variant to distributing a GlobeImposter variant that appends the .crypt extension. This malspam campaign is called Blank Slate due to the lack of a subject line and message body in the spam emails. 

You can see an example of what a Blank Slate malspam email looks like below.

These malspam emails contain ZIP attachments that are named using the format EMAIL_[RandomNumbers]_[RecipientName].zip. Inside this zip file is another zip file with a name like [RandomNumbers].zip. This zip file then contains a random named obfuscated JS script. So an example attachment progression would be something like -> -> msaSh.js.

When executed, this JS script will attempt to download a file called 1.dat, which is a actually an executable file, from one of two designated sites. An example of this JS installer can be seen below.

An interesting characteristic of the current downloaded malware executable is that it is code signed using a certificate issued by thawte.

After the executable is downloaded, it will be executed to install whatever the current malware payload is. In this case the installed malware is a GlobeImposter variant that appends the .crypt extension to encrypted files.

When GlobeImposter encrypts files it will also create a ransom note named !back_files!.html in each folder a file is encrypted.  This ransom note contains instructions to contact for payment instructions and the ransom amount.
