SiS Revealed: The Silent Betrayer Inside RPI Finally Caught in Digital Shadows In the fast-paced world of embedded systems and real-time computing, few companies operate as discreetly—and yet as influentially—as SiS (SystemIC, now part of SiS Group). While widely recognized for delivering high-performance processors for industrial automation, robotics, and edge computing, a shadow has recently been exposed: a covert vulnerability embedded in one of their core RPI (Raspberry Pi-like Edge Compute Modules) platforms—later dubbed the “silent betrayer” among developers and security analysts alike. ### The Hidden Flaw: SiS RPI and Undisclosed Backdoor Exposure Though SiS has long maintained a reputation for innovation and reliability, recent forensic analysis and independent security audits uncovered unsettling evidence: an unauthorized, undocumented backdoor intentionally integrated into select RPI firmware versions. This exploit, subtle and expertly concealed, allowed remote code execution under specific conditions—posing a serious threat to critical infrastructure, smart manufacturing, and digital sovereignty in edge environments.
