We have just received a sample email that seems to be the start of it all. See below for the sample email being spammed with the copy of the worm attached.
This email sample has no connection with the email samples that can be found in the worm’s binary. This must have been the initial seeding of the first copies of worm.
The sample has been given the detection name WORM_BAGLE.EN.
