Here is what I found:

Mail Subject



Variants .A, .C, and .D compose the email subject line from a list in the worm's body. This list is the same for each of these three variants.

Variants .E and .F compose the email subject line from a list in the worm's body. This list is the same for variants .E and .F.

For variants .G, .H, and .I, the subject of the email is composed in a complex manner, but also taken from a list in the worm's body.
