Background
SentinelLABS tracks fast16 as a cyber-sabotage framework whose central components originate as far back as 2005. The fast16.sys driver homes in on high-precision calculation software, modifying its code in memory to corrupt the output. Paired with self-spreading capabilities, the payload is intended to introduce the same faulty results throughout an entire facility. The 'fast16' label appears in the ShadowBrokers' leak of the NSA's 'Territorial Dispute' components.
