Joseph Carson, chief security scientist at ThycoticCentrify, told IT Pro that this highlights and reminds us how bad password hygiene is getting and how important it is for organizations to priorities password security and management. The amount of chemicals it would take to cause harm to people.the numbers are astronomical.” “For a large impact, there has to be a large change in the chemicals in the system. “It takes a lot to influence a water supply chain,” he said.
“No one tried to poison any of our water,” he told the newspaper. The shared TeamViewer password was reported earlier by the Associated Press.According to some reports, the hacker "tried to poison" the area's water, but Michael Sena, executive director of the Northern California Regional Intelligence Center, told the San Francisco Chronicle there was no attempt to poison the water supply. Even if the change hadn’t been reversed, the officials said, treatment plant personnel have redundancies in place to catch dangerous conditions before water is delivered to homes and businesses. In larger doses, the chemical is a health hazard.Ĭhristopher Krebs, the former head of the Cybersecurity and Infrastructure Security Agency, reportedly told a House of Representatives Homeland Security committee on Wednesday that the breach was “very likely” the work of “a disgruntled employee.”Ĭity officials said residents were never in danger, because the change was quickly detected and reversed. Lye is used in small amounts to adjust drinking water alkalinity and remove metals and other contaminants. The person on the other end changed the amount of lye added to the water from about 100 parts per million to 11,100ppm. The breach occurred around 1:30pm, when an employee watched the mouse on his city computer moving on its own as an unknown party remotely accessed an interface that controlled the water treatment process. The lack of a firewall and a password that was the same for each employee are also signs that the department’s security regimen wasn’t as tight as it could have been.

Windows 7 also provides fewer security protections than Windows 10. In January, Microsoft ended support for Windows 7, a move that ended security updates for the operating system. The revelations illustrate the lack of security rigor found inside many critical infrastructure environments. It said: AdvertisementĮmployees in Oldsmar’s water treatment department and city manager’s office didn’t immediately respond to phone messages seeking comment for this post. Further, all computers shared the same password for remote access and appeared to be connected directly to the Internet without any type of firewall protection installed.Ī private industry notification published by the FBI provided a similar assessment.
All computers used by water plant personnel were connected to the SCADA system and used the 32-bit version of the Windows 7 operating system. The unidentified actors accessed the water treatment plant’s SCADA controls via remote access software, TeamViewer, which was installed on one of several computers the water treatment plant personnel used to conduct system status checks and to respond to alarms or any other issues that arose during the water treatment process.
What’s more, the computer had no firewall installed and used a password that was shared among employees for remotely logging in to city systems with the TeamViewer application. The tampering could have caused severe sickness or death had it not been for safeguards the city has in place.Īccording to an advisory from the state of Massachusetts, employees with the Oldsmar facility used a computer running Windows 7 to remotely access plant controls known as a SCADA-short for “supervisory control and data acquisition”-system. After gaining remote access to a computer that controlled equipment inside the Oldsmar water treatment plant, the unknown intruder increased the amount of sodium hydroxide-a caustic chemical better known as lye-by a factor of 100.
