EMOTET
In the past week, the massive sending of MalSpam emails to spread the Emotet malware, resumed.
Malspam emails contain either an Excel attachment inside or a ZIP file with a password that itself contains an Excel file.
Below we see the number of unique hashes of attachments monitored on different days of the week:

 

In the next graph we see the number of Malspam emails from Emotet examined on different days of the week:


Examining the TOP 10 Real Senders on the first day (02/11) of the resumption of malspam sending, we can see that Brazil, Japan and Italy were the most affected countries:

On computers infected with Emotet, the IcedID malware was dropped through the Anubis Loader.
The first Loader of IcedID was dropped on 03/11 at ~21:00 CET with hash F4239E545B7E85527BABCF8CB130DF6F
The second Loader of IcedID was dropped on 04/11 at ~16:00 CET with hash 45FE1342304237C4AD62DF5F861B5A16

The IcedID Loader downloads the final IcedID payload from the https[:]//bayernbadabum.]com/botpack.dat and contact the C2:
  • s://newscommercde.]com/users/1139942657/35<redacted>
  • s://spkdeutshnewsupp.]com/news/1/255/0
To send the victim's machine information.
The Botnet id is: 1139942657

The final DLL of IcedID is saved in %appdata%\<user>\<random>.dll or in %localappdata%\<random folder>\<random>.dll (hash EB4D93C4C9A363491875E34AA8FD37F8)
Persistence is achieved through the Windows Task.

Below are images of the IcedID loader dumps.
