The attack permits the malware to jump onto computers in a unique manner, using the ‘Range’ HTTPS header. The Ursnif malware is retrieved from the command and control server when the malware requests the file, but should a user browse to that location they see this JPG of the kangaroo below. The email uses a macro-laden Microsoft office document attachment, purporting to be from the Australian Taxation Office; with taxation proving to be a popular lure in 2016. The researchers also found that the malware authors made a mistake in their encryption routine, unintentionally making it easier for researchers to understand their techniques. Carl Leonard, principal security analyst at Raytheon|Websense have the following comments on it.

“Cybercriminals are always on the lookout for new ways of fooling unsuspecting victims into running their malicious code and evading researchers and investigators.

“Financially motivated crime remains more popular than ever among these actors and they will use any means necessary to obtain user credentials and personal information. It is vital that users remain aware of suspicious emails and never open anything they are unsure about or is from someone they don’t know.

“However, this attack also provides proof that cybercriminals are humans and as such they will make mistakes, which we as defenders can use to our advantage.”[/su_note]
