A U.K. water supplier suffered a disruption in its corporate IT systems Monday as a result of a cyber-attack but claims that its water supply was not affected.

The alleged attack perpetrator-the Clop ransomware group-claimed the attack was on another, larger water utility, which for its part indignantly called the claim a "Cyber hoax."

The Clop ransomware gang took responsibility for an attack on a U.K. water supplier on its dark web site, but said the victim was Thames Water and not South Staffordshire, according to a report posted on Bleepingcomputer.

Further inspection of stolen data dumped from the attack on the Clop site appears to confirm Thames Water's assurance, as it includes a spreadsheet of usernames and passwords featuring South Staff Water and South Staffordshire email addresses, according to Bleepingcomputer.

Last year a glimpse of what could be possible in a successful attack on a water supply occurred when an attacker hacked a water treatment facility in Oldsmar, Fla., and raised the levels of sodium hydroxide, or lye, in the water.

An operator quickly noticed the attack and corrected the lye levels in the water before any significant damage was done, but the attack could have been extremely dangerous had it not been thwarted quickly, officials said at the time.
