The event
A major exploit pattern dubbed "LLMjacking" emerged where attackers used stolen cloud credentials to hijack enterprise AI cloud services, generating massive unauthorized compute bills. Attackers targeted organizations running large language models on cloud platforms - AWS, Azure, GCP - using compromised API keys and access tokens to consume GPU resources at scale. The hijacked compute was used for everything from cryptocurrency mining to running the attackers' own AI workloads on their victims' cloud accounts. Some enterprises discovered six-figure compute charges before detecting the unauthorized access.
What the machine did
The cloud platforms' automated provisioning systems allocated GPU resources on demand without human verification of unusual consumption patterns. An API key requesting $50,000 in GPU compute in a single day was treated identically to a legitimate workload. The automated billing systems processed the charges without alerting a human. No anomaly detection flagged a 100x spike in compute consumption. The same automation that makes cloud AI accessible also made it exploitable at scale.
Where the failure landed
Enterprises hit with six-figure cloud computing bills from hijacked AI services. Stolen credentials traded on dark web markets specifically for LLMjacking. The attack pattern became a standard offering in cybercrime-as-a-service ecosystems. Cloud providers were slow to implement consumption anomaly alerts, leaving customers to discover the theft through billing statements.

Trust boundaries, least privilege, and output approval
The failure pattern in this case: Untrusted input crossed a privileged boundary.
The moment the path could change
A security owner approves credential scope and externally visible actions before the agent can cross a trust boundary.
Autonomy is a design choice.
