Hackers destroem bomba de água

Este caso é interessante por diversas razões (tanto quanto é possível perceber): 1) foi um ataque real a uma infraestrutura crítica (rede pública de distribuição de água); 2) foi um ciber-ataque mas causou danos físicos (a destruição de uma bomba de água); 3) a intrusão prolongou-se por meses sem ser detectada. Oh brave new world...

Water utility hackers destroy pump, expert says
SCADA breach 'a really big deal'
The Register, Dan Goodin, 17th November 2011 22:03 GMT

Hackers destroyed a pump used by a US water utility after gaining unauthorized access to the industrial control system it used to operate its machinery, a computer security expert said.

Joe Weiss, a managing partner for Applied Control Solutions, said the breach was most likely performed after the attackers hacked into the maker of the supervisory control and data acquisition software used by the utility and stole user names and passwords belonging to the manufacturer's customers. The unknown attackers used IP addresses that originated in Russia.

Weiss cited an official government report from the state where the regional water district was located. It was dated November 10, two days after the hack was discovered. The document indicates that the utility had been experiencing unexplained problems with its computerized system in the weeks leading up to the breach.

“Over a period of two to three months, minor glitches had been observed in remote access to the water district's SCADA system,” Weiss said during an interview, in which he read a verbatim portion of the document to The Register. He said that the attackers were able to burn out one of the utility's pumps by causing either the pump or the SCADA system that controlled it to turn on and off “repeatedly.”

Weiss said he obtained the report on the condition that the water utility and the state where it's located aren't disclosed. A statement issued by the US Department of Homeland Security indicated the utility was located in Springfield, Illinois. Weiss published bare-bones details of the hack on Thursday because he wanted to bring attention to an incident he said raised serious concerns about the ability of the US government to secure critical infrastructure.

“This is really a big deal, and what's just as big a deal is what isn't being said or isn't being done,” Weiss said. “What the hell is going on with DHS? Why aren't people being notified?”

He said he's unaware of any water utilities or other SCADA operators who know about the attack.

In an email sent several hours after this article was first published, DHS spokesman Peter Boogaard wrote: "DHS and the FBI are gathering facts surrounding the report of a water pump failure in Springfield Illinois. At this time there is no credible corroborated data that indicates a risk to critical infrastructure entities or a threat to public safety."
