Another day another bit of e-mail junk.
This one came to me from an AOL email account (using an authenticated AOL user thereaty5@aol.com) submitted by IP 41.138.164.240. The mail was sent to an address scraped from the internet.
inetnum: 41.138.164.0 - 41.138.165.255 netname: VISAFONE-PH-PDSN1 descr: Visafone Communications Limited, descr: 12, Ologun Agbaje Street, descr: Victoria Island, descr: Lagos country: NG
Interestingly enough Visafone normally is associated with financial 419 scams and it is the first time I’ve seem malware emanate from Nigeria.
The file attached was:

Both sites had never seen the file before.
It then extracts another file and launches it.

This component had been seen before but is not detected by any AV.
Once run it uses an unusual method to ex-filtrate data. sends a series of emails using SMTP server mx1.3owl.com on port 587. The first message informs the malware owner the system has been infected.

So poorly done. The mail is submitted using AUTH with the details of the mail account!

oops!
Additionally another address seems related to this: ab.frankmoore@live.com (friendly name of “Wofa Group Plc”, which appears on one website as a company in… Nigeria) which was also used in September 2013 to send similar “please open the attached” malware type email. In some test messages the IP 41.138.164.31 (similar to the one above) registered at Nigeria’s VISAFONE was used to submit via webmail.
At the time of researching and writing this document it seems nobody has fallen for this other than researchers. (tag: ubapaul)
