Protecting sensitive, precision-timed computing systems requires understanding the nature of cyberthreats. So researchers from Washington State University teamed up with experts at the University of Colorado Colorado Springs and Metro State University to design an attack—dubbed NosyNeighbor—that lurks on the sidelines of time- and safety-critical computer systems, "infers" what's happening inside and adapts its malicious approach.

Security researchers have devised a novel side-channel exploit designated as the NosyNeighbor attack, capable of determining the operational status of individual components within mission-critical infrastructure solely by analyzing task execution timing. During experimental evaluations, this sophisticated methodology successfully bypassed prevalent defensive mechanisms, identifying active software processes with an impressive 73% accuracy. Targeting Isolated Real-Time Architectures Engineered specifically to probe real-time operating systems (RTOS), the NosyNeighbor attack threatens environments embedded within avionics, cardiac pacemakers, and automotive braking infrastructure domains where a latency of merely a few milliseconds can precipitate catastrophic physical failure.
