The package is a new version of the previously removed libhmac. The key parts, a malicious payload to inject into hijacked browser extensions, is not included in the package. The code allows hijacking browser extensions to - based on previous package - exfiltrate credentials. This package also contains code to create hidden SSH access to the machine with hardcoded credentials.
