  • Russian hackers are suspected of causing a Texas town's water tank to overflow earlier this year.
  • Cybersecurity experts say the likely culprit is Sandworm, a Russian hacking group.
  • The US has also previously accused Sandworm of attacks in 2017 on hospitals in Pennsylvania.

In January, a Texas town's water tank suddenly started overflowing, spewing a torrent of water to the ground below.

The deluge was contained within an hour. But it's raising concerns this week, after the cybersecurity firm Mandiant said Wednesday that Russian hackers were likely behind it.

Mandiant, which is owned by Google, attributed the attack in Muleshoe, Texas to Sandworm, a Russian hacking group.
