(Image credit: Getty Images) Security researchers have uncovered a cyber-sabotage platform that predates Stuxnet by at least half a decade. Sentinel Labs has published a blog on their fast16 revelations, discussing the scope of this state-level tool, which targets select high-precision calculation software, slyly introducing inaccuracies. Investigations suggest that fast16 was used to make key calculations in software used for projects involving nuclear reactors, dam design, and broader physics simulations, subtly but reproducibly erroneous. “*** Nothing to see here – carry on ***” The security researchers, including Vitaly Kamluk & Juan Andrés Guerrero-Saade, found fast16 based on an architectural hunch. As a number of high-tier threats in this category were built on an embedded Lua virtual machine , they decided to see if there were traces of earlier Lua VM tools.
