Previously, GitHub was used to distribute malicious software directly, with a malicious script downloading either raw encrypted scripting code or malicious executables. Their tactics have now changed and evolved. Threat actors now operate a network of “Ghost” accounts that distribute malware via malicious links on their repositories and encrypted archives as releases. This network not only distributes malware but also provides various other activities that make these “Ghost” accounts appear as normal users.
