Researchers at SentinelOne have discovered a previously unknown malware framework called 'fast16,' which dates back to 2005. This Lua-based malware was designed to target high-precision calculation software, which is often used in engineering and industrial applications. The malware predates the infamous Stuxnet worm, which was aimed at disrupting Iran's nuclear program. The implications of fast16 are significant as it shows that cyber sabotage efforts have been in play for much longer than previously thought, raising concerns about the security of critical infrastructure and industrial systems. Companies using this type of software need to be aware of the potential risks and take steps to protect their systems.
