PyFlash
Description
(ESET) This second stage backdoor is a py2exe executable. py2exe is a Python extension to convert a Python script into a standalone Windows executable. To our knowledge, this is the first time the Turla developers have used the Python language in a backdoor.
The backdoor communicates with its hardcoded C&C server via HTTP. The C&C URL and other parameters such as the AES key and IV used to encrypt all network communications are specified at the beginning of the script.
The C&C server can also send backdoor commands in JSON format. The commands implemented in this version of PyFlash are: • Download additional files from a given HTTP(S) link. • Execute a Windows command using the Python function subprocess32.Popen. • Change the execution delay: modifies the Windows task that regularly (every X minutes; 5 by default) launches the malware. • Kill (uninstall) the malware.
