The threat actor TA505 has begun distributing a new malware downloader known as AndroMut, the security firm Proofpoint claims, adding that this downloader pulls down a remote access trojan that it has called FlawedAmmyy.

The malware only affects Windows systems.

Two campaigns were observed downloading FlawedAmmyy, one targeting South Korea and using a Microsoft Office file containing macros that then ran a Msiexec command to bring in the FlawedAmmyy RAT.

The second campaign was aimed at financial institutions in Singapore, the UAE and the US. In this case, a Microsoft Word or Microsoft Excel file used macros to run commands that resulted in the malware being downloaded.

The AndroMut downloader achieved persistence on Windows systems by either scheduling a task that ran a created LNK file in the Recycle Bin or else used the Registry run method to regenerate itself.

Asked about the origins of TA505, a Proofpoint spokesperson told iTWire that its researchers had assessed with medium confidence that the individuals known as TA505 were originally from Eastern European countries.

"But they have no knowledge that TA505 is a state actor," the spokesperson added.

Proofpoint has tracked TA505 for some time and in January reported that the actor had begun to distribute a new Windows backdoor named ServHelper.
