CyberheistNews Vol 16 #04 The Skeleton Key: How Attackers Weaponize Trusted RMM Tools for Backdoor Access

This CyberheistNews issue describes a two-stage campaign dubbed “The Skeleton Key” where attackers first harvest credentials through convincing Greenvelope-themed phishing and then use those credentials to generate RMM access tokens and deploy a payload ("GreenVelopeCard.exe") to turn trusted Remote Monitoring and Management tools into persistent backdoors; the newsletter also covers LinkedIn comment phishing, weaponized AI enabling large-scale scams, and reports on crypto theft and training gaps.
