Executive Summary SentinelLABS has uncovered a previously undocumented cyber sabotage framework whose core components date back to 2005, tracked as fast16. fast16.sys selectively targets high-precision calculation software, patching code in memory to tamper with results. By combining this payload with self-propagation mechanisms, the attackers aim to produce equivalent inaccurate calculations across an entire facility. This 2005 attack is a harbinger for sabotage operations targeting ultra expensive high-precision computing workloads of national importance like advanced physics, cryptographic, and nuclear research workloads. fast16 predates Stuxnet by at least five years, and stands as the first operation of its kind. The use of an embedded customized Lua virtual machine predates the earliest Flame samples by three years. The name ‘fast16’ is referenced in the infamous ShadowBrokers’ leak of NSA’s ‘Territorial Dispute’ components.…
