Turns out that Florida water treatment facility left the doors wide open for hackers

By now, you’ve in all probability heard the theoretically scary story of how hackers managed to infiltrate the pc techniques at a water therapy plant in Oldsmar, Florida and remotely management the chemical ranges — but it surely seems that description offers the hackers far, far an excessive amount of credit score.

The truth? The water therapy plant itself left off-the-shelf distant management software program on these crucial computer systems — and apparently by no means, ever bothered to alter the password.

An official cybersecurity advisory in regards to the incident from the state of Massachusetts (through Ars Technica) explains that the SCADA management system was accessed through TeamViewer, the type of distant desktop software an IT administrator would possibly roll out to remotely troubleshoot computer systems — not one thing you’d typically need hooked as much as a crucial system. Extra importantly, and right here I’ll simply quote the Massachusetts report verbatim:

Additional, all computer systems shared the identical password for distant entry and gave the impression to be related on to the Web with none kind of firewall safety put in.

Sure, simply like Florida’s Department of Health, this Florida water therapy plant apparently didn’t trouble to challenge particular person passwords for software program that might give anybody full entry to any of their computer systems and their water therapy system.

In different phrases, any worker might modify your complete city’s water provide on a whim from wherever on the earth. Which might be what occurred: former US cybersecurity czar Christopher Krebs testified earlier today that it was “very seemingly” an insider, presumably a disgruntled worker. Somebody who would have already got entry, which wouldn’t make this a lot of a “hack” in any respect.

It’s not just like the water therapy plant was even utilizing that software program, by the best way: Pinellas County Sheriff Bob Gualtieri stated the plant had really stopped utilizing TeamViewer six months in the past, according to The Wall Street Journal.

It ought to in all probability go with out saying that you just shouldn’t go away crucial public infrastructure simply accessible from wherever on the earth, however the FBI is saying it anyhow, according to ZDNet; the company despatched out an alert as we speak warning in opposition to TeamViewer, dangerous passwords and Home windows 7, which Microsoft no longer supports with security updates however the water therapy plant nonetheless had put in.

Sadly, studies at Vice and Cyberscoop counsel that lax safety (together with TeamViewer particularly) and growing older infrastructure are all too widespread at small public utilities, which can not have the finances, experience and even the power to regulate their very own safety techniques, which are sometimes farmed out to 3rd events.

The excellent news is {that a} plant operator rapidly seen the intrusion, reversed it, and it appears nobody was harmed.
