For decades, virtualization software has offered a way to vastly multiply computers’ efficiency, hosting entire collections of computers as “virtual machines” on just one physical machine. And for almost as long, security researchers have warned about the potential dark side of that technology: theoretical “hyperjacking” and “Blue Pill” attacks, where hackers hijack virtualization to spy on and manipulate virtual machines, with potentially no way for a targeted computer to detect the intrusion. That insidious spying has finally jumped from research papers to reality with warnings that one mysterious team of hackers has carried out a spree of “hyperjacking” attacks in the wild.

Today, Google-owned security firm Mandiant and virtualization firm VMware jointly published warnings that a sophisticated hacker group has been installing backdoors in VMware’s virtualization software on multiple targets’ networks as part of an apparent espionage campaign. By planting their own code in victims’ so-called hypervisors—VMware software that runs on a physical computer to manage all the virtual machines it hosts—the hackers were able to invisibly watch and run commands on the computers those hypervisors oversee. And because the malicious code targets the hypervisor on the physical machine rather than the victim’s virtual machines, the hackers’ trick multiplies their access and evades nearly all traditional security measures designed to monitor those target machines for signs of foul play.
