Florida water treatment facility hack used a dormant remote access software, sheriff says

The cyber-intruder received into Oldsmar’s water therapy system twice on Friday — at eight a.m. and 1:30 p.m. — by means of a dormant software program referred to as TeamViewer. The software program hadn’t been utilized in about six months however was nonetheless on the system.

“How they received in, whether or not it was by means of a password or by means of one thing else, I am unable to inform you that,” mentioned Gualtieri.

Nevertheless, Oldsmar’s assistant metropolis supervisor, Felicia Donnelly, advised CNN {that a} password was required for the system to be managed remotely.

TeamViewer, which is predicated in Germany and has greater than half 1,000,000 clients around the globe utilizing business licenses, mentioned that there was no indication of suspicious exercise.

“Primarily based on cooperative info sharing, a diligent technical investigation didn’t discover any indication for suspicious connection exercise by way of our platform,” TeamViewer spokesperson Martina Dier advised CNN on Wednesday.

As soon as contained in the system, the hacker adjusted the extent of sodium hydroxide, or lye, to greater than 100 occasions its regular ranges, Gualtieri mentioned. The system’s operator observed the intrusion and instantly diminished the extent again. At no time was there a major adversarial impact to the town’s water provide, and the general public was by no means at risk, he mentioned.

The id of the hacker, or hackers, is not but recognized. Gualtieri praised the operator who noticed the assault on Friday and mentioned present and former staff have been interviewed after early consideration of an insider menace. There are at present no suspicions or indications that is the case, he mentioned.

The incident highlights how some essential infrastructure methods are susceptible to hacking as a result of they’re on-line and use distant entry packages, typically with lax safety.

Vulnerabilities in essential infrastructure methods

Gualtieri mentioned the water therapy facility at present makes use of a Google Chrome product for distant entry. The Oldsmar water therapy system can also be utilizing the Home windows 7 working system, which was launched in 2009, a supply conversant in the investigation mentioned.

The outdated working system was not the weak point right here provided that the hacker didn’t exploit a vulnerability, in keeping with Rob Lee, the CEO of cybersecurity agency Dragos.

“There was software program that permits distant entry that was web uncovered, which implies anybody may log in,” he mentioned. “To influence industrial methods you do not want exploits. You simply must know how one can use the system — on this case a human machine interface that operated the plant.”

Distant entry software program, like TeamViewer and Chrome in Oldsmar’s case, are extraordinarily widespread on infrastructure websites, Lee mentioned. That makes them targets.

“The truth is although for 1000’s of websites, particularly amongst the smaller group members, this similar state of affairs is feasible,” he mentioned.

Chris Krebs, the previous director of the Division of Homeland Safety’s Cybersecurity and Infrastructure Safety Company, wrote on Wednesday that the Oldsmar hack highlights how dire the problem is.

“Sadly, that water therapy facility is the rule slightly than the exception,” Krebs wrote in a column for The Hill. “When a corporation is struggling to make payroll and to maintain methods on a era of know-how created within the final decade, even the fundamentals in cybersecurity typically are out of attain.”

Significance of distant entry software program

Lee mentioned one of these assault is exactly what retains business consultants awake at night time.

“It was not significantly subtle, nevertheless it’s precisely what of us fear about, and as one in all a only a few examples of somebody attempting to harm individuals, it is a huge deal for that motive,” Lee mentioned.

Nevertheless, Gualtieri rejected hypothesis that the assault wasn’t subtle.

“It might be that anyone by some means compromised the password and the password received out. Or it might be fairly subtle the place you have received anyone who’s doing what intrusion hackers do: wanting on the market on a regular basis for potential vulnerabilities and administrator credentials,” he mentioned.

Gualtieri mentioned the potential hazard of an assault like this could immediate a dialogue about distant entry to software program, including that he’d by no means seen an assault like this.

“This can be a new one for us,” the sheriff mentioned.

Damon Small, the technical director of safety consulting at NCC Group North America, advised CNN that distant entry was a key a part of essential infrastructure and cautioned in opposition to demonizing it.

“Distant entry is used on a regular basis. That is not the failure right here. The failure was that somebody received ahold of it,” he mentioned.

Israel reaches out to US investigators

Gualtieri mentioned the county is coordinating with the FBI and US Secret Service, however the county is taking the lead on the investigation, utilizing an in-house lab for the forensic evaluation of the assault.

Requested why the Secret Service is concerned, Gualtieri pointed to their work on pc fraud and agreed Sunday’s Tremendous Bowl in Tampa “definitely has one thing to do with it,” provided that the assault occurred Friday. The assault was reported to the FBI’s Joint Terrorism Process Power, which the Secret Service is part of, “so that they have been concerned at that time.”

Israel’s Nationwide Cyber Directorate (NCD), the cybersecurity authorities company, mentioned Wednesday that they had reached out to counterparts within the US investigating the Oldsmar hack.

“The Israel Nationwide Cyber Directorate has contacted its US equivalents in regards to the case (in Oldsmar, FL) as a part of customary and accepted information-sharing within the cyber discipline, which is meant to study from different circumstances on this planet and increase the strategies of resistance,” the establishment mentioned in an announcement.

Final April, Israeli water services have been focused in an assault that NCD head Yigal Unna described as a “altering level within the historical past of recent cyber warfare.” He mentioned the services have been focused in a “synchronized and arranged assault geared toward our water methods.”

Had the assault been profitable, Unna mentioned, it may have brought on important injury to civilian water provides. He additionally appeared to recommend the hack focused chlorine circulation into water therapy items, which may have been dangerous to public well being.

In his Might 2020 presentation to an internet CyberTech convention, the NCD head didn’t say who he believed was behind the assault in Israel, however famous it had not been accompanied by the kind of ransom calls for or try to achieve financially that might be anticipated if it had been carried out by cyber criminals.
