Rewterz Threat Alert – Lazarus Injector – IOC’s

October 4, 2019

Severity

High

Analysis Summary

Recently, a VirusTotal submitter uploaded a file that was digitally signed with the same certificate as two previously reported Lazarus tools. Like one of those tools, this newly uploaded malware appears to act as an injector, although it behaves significantly differently.
The digital signature of this file matches the signature used on two Lazarus tools discussed in open source.

Operation

The injector expects four command line parameters to be present on operation:

– The path of the injector, which under normal circumstances is automatically part of the command line
– An integer value (1 or 2) that specifies the operational mode (inject or eject)
– A process identifier (PID) value that specifies a target process
– A path to the DLL to be injected into the target PID

The malware first checks that there are a total of four parameters present before validating their content. Next, it uses the PathFileExistsA API call to validate the path to the DLL to be injected. The injector also contains debugging messages. These items are all visible in the image below.

Next, the malware checks that an integer has been supplied as a PID and that either the integer 1 or the integer 2 have been supplied for the operational argument. Curiously, dynamic debugging suggests that the PID check will still pass as long as an integer is the first digit (for example, passing “94a” will still cause the malware to attempt to inject or eject a DLL from a process with an invalid PID, although this will fail the OpenProcess attempts).
