Another Document Targeting Uyghur Mac Users

We spotted a new variant of the documents used in the cyber attacks against Uyghur back in February.

This variant was first submitted to VirusTotal on April 11 from China. This time it uses IUHRDF, which may be a reference to International Uyghur Human Rights & Democracy Foundation, instead of Captain as the author:

Properties of poadasjkdasuodrr.doc

The payload is still the same besides using different filenames and command and control server.

It uses “alma.apple.cloudns.org” as the command and control server:

Command and control server name

It creates the following copy of itself and launch point:

~/Library/Application Support/.realPlayerUpdate
~/library/launchagents/realPlayerUpdate.plist

Or it may create the following instead (when executed with 2 parameters):

/Library/Application Support/.realPlayerUpdate
/library/LaunchDaemons/realPlayerUpdate.plist

It remains pretty much the same malware and is generically detected as Backdoor:OSX/CallMe.A since February.
