The Russian hacking group Sandworm, linked to the GRU, conducted a cyber attack on Muleshoe, Texas water system.

Sandworm has a history of international cyber attacks, including Ukraine's power grid and the 2018 Olympic Games.

The attack on Muleshoe is the first known instance of Sandworm targeting US public infrastructure.

Six Sandworm members have been indicted by the US DOJ for various cybercrimes, including the disruptive NotPetya virus.

US infrastructure's cyber vulnerability is highlighted by this incident, prompting an FBI investigation.

Mandiant reports that Sandworm's activities have extended to water systems in Europe and have increased the threat of cyber attack proliferation.

Despite the Biden administration's efforts, a key EPA cybersecurity directive for water facilities was rescinded.

US officials are calling for strengthened cyber defenses at water treatment facilities in response to these threats.
