Security firms have verified that the Fast16 malware was employed to stealthily disrupt simulated nuclear weapons explosion tests. Rather than directly damaging the weapons, this software deceives engineers by manipulating test data, leading them to believe that the nuclear tests have been unsuccessful. This, in turn, hinders the advancement of the nuclear program. Fast16 specifically targets at least two professional simulation software applications, LS-DYNA and AUTODYN, and covertly modifies the calculation outcomes in simulations involving high explosives and nuclear weapons.
