Inside Jahoo (Otlard.A ?) - A spam Botnet

Trash and Mailbox by Bethesda Softworks



Otlard.A (or let's say at least the malware triggering 2806902 || ETPRO TROJAN Win32.Otlard.A C&C Checkin response )  is a Spam Botnet

I saw it loaded as a plugin in an instance of Andromeda

That Andromeda is being spread via :


  • Bedep build id 6005 and here 6007 from an Angler EK fed by Malvertising :


VirtualDonna group redirecting traffic to an Angler instance loading Bedep buildid 6007 in memory
Bedep 6007 loading Andromeda 55ead0e4010c7c1a601511286f879e33 before update task.

Note : Bedep 6007 was sometimes loading it with other payload

Here the Otlard.A task in that Andromeda instance :

Now here is what the control panel of that plugin looks like :
