Hackers tied to Russia’s GRU focused the US grid for years

For all of the nation-state hacker teams that have targeted the United States power grid—and even successfully breached American electric utilities—solely the Russian army intelligence group often known as Sandworm has been brazen sufficient to set off precise blackouts, shutting the lights off in Ukraine in 2015 and 2016. Now one grid-focused safety agency is warning {that a} group with ties to Sandworm’s uniquely harmful hackers has additionally been actively focusing on the US power system for years.

On Wednesday, industrial cybersecurity agency Dragos revealed its annual report on the state of commercial management methods safety, which names 4 new international hacker teams centered on these important infrastructure methods. Three of these newly named teams have focused industrial management methods within the US, in keeping with Dragos. However most noteworthy, maybe, is a bunch that Dragos calls Kamacite, which the safety agency describes as having labored in cooperation with the GRU’s Sandworm. Kamacite has previously served as Sandworm’s “entry” group, the Dragos researchers write, centered on gaining a foothold in a goal community earlier than handing off that entry to a unique group of Sandworm hackers, who’ve then typically carried out disruptive results. Dragos says Kamacite has repeatedly focused US electrical utilities, oil and gasoline, and different industrial companies since as early as 2017.

“They’re repeatedly working towards US electrical entities to attempt to preserve some semblance of persistence” inside their IT networks, says Dragos vice chairman of risk intelligence and former NSA analyst Sergio Caltagirone. In a handful of instances over these 4 years, Caltagirone says, the group’s makes an attempt to breach these US targets’ networks have been profitable, resulting in entry to these utilities that is been intermittent, if not fairly persistent.

Caltagirone says Dragos has solely confirmed profitable Kamacite breaches of US networks prior, nevertheless, and has by no means seen these intrusions within the US result in disruptive payloads. However as a result of Kamacite’s historical past contains working as a part of Sandworm’s operations that triggered blackouts in Ukraine not once, but twice—turning off the facility to 1 / 4 million Ukrainians in late 2015 after which to a fraction of the capital of Kyiv in late 2016—its focusing on of the US grid ought to increase alarms. “In case you see Kamacite in an industrial community or focusing on industrial entities, you clearly cannot be assured they’re simply gathering info. You must assume one thing else follows,” Caltagirone says. “Kamacite is harmful to industrial management services as a result of once they assault them, they’ve a connection to entities who know methods to do damaging operations.”

Dragos ties Kamacite to electrical grid intrusions not simply within the US, but additionally to European targets effectively past the well-publicized assaults in Ukraine. That features a hacking marketing campaign towards Germany’s electrical sector in 2017. Caltagirone provides that there have been “a few profitable intrusions between 2017 and 2018 by Kamacite of commercial environments in Western Europe.”

Dragos warns that Kamacite’s essential intrusion instruments have been spear-phishing emails with malware payloads and brute-forcing the cloud-based logins of Microsoft companies like Workplace 365 and Energetic Listing in addition to digital personal networks. As soon as the group positive aspects an preliminary foothold, it exploits legitimate consumer accounts to keep up entry and has used the credential-stealing tool Mimikatz to unfold additional into victims’ networks.

“One group will get in, the opposite… is aware of what to do”

Kamacite’s relationship to the hackers often known as Sandworm—which has been identified by the NSA and US Justice Department as Unit 74455 of the GRU—is not precisely clear. Menace intelligence firms’ makes an attempt to outline distinct hacker teams inside shadowy intelligence companies just like the GRU have at all times been murky. By naming Kamacite as a definite group, Dragos is looking for to interrupt down Sandworm’s actions in another way from others who’ve publicly reported on it, separating Kamacite as an access-focused group from one other Sandworm-related group it calls Electrum. Dragos describes Electrum as an “results” group, liable for damaging payloads just like the malware known as Crash Override or Industroyer, which triggered the 2016 Kyiv blackout and may have been intended to disable safety systems and destroy grid equipment.

Collectively, in different phrases, the teams Dragos name Kamacite and Electrum make up what different researchers and authorities companies collectively name Sandworm. “One group will get in, the opposite group is aware of what to do once they get in,” says Caltagirone. “And once they function individually, which we additionally watch them do, we clearly see that neither is excellent on the different’s job.”

When WIRED reached out to different threat-intelligence companies together with FireEye and CrowdStrike, none may verify seeing a Sandworm-related intrusion marketing campaign focusing on US utilities as reported by Dragos. However FireEye has beforehand confirmed seeing a widespread US-targeted intrusion campaign tied to another GRU group known as APT28 or Fancy Bear, which WIRED revealed final yr after acquiring an FBI notification e-mail despatched to targets of that marketing campaign. Dragos identified on the time that the APT28 marketing campaign shared command-and-control infrastructure with one other intrusion try that had focused a US “power entity” in 2019, in keeping with an advisory from the US Division of Vitality. Provided that APT28 and Sandworm have worked hand-in-hand in the past, Dragos now pins that 2019 energy-sector focusing on on Kamacite as a part of its bigger multiyear US-targeted hacking spree.

Vanadinite and Talonite

Dragos’ report goes on to call two different new teams focusing on US industrial management methods. The primary, which it calls Vanadinite, seems to be have connections to the broad group of Chinese hackers known as Winnti. Dragos blames Vanadinite for assaults that used the ransomware often known as ColdLock to disrupt Taiwanese sufferer organizations, together with state-owned power companies. However it additionally factors to Vanadinite focusing on power, manufacturing, and transportation targets world wide, together with in Europe, North America, and Australia, in some instances by exploiting vulnerabilities in VPNs.

The second newly named group, which Dragos calls Talonite, seems to have focused North American electrical utilities, too, utilizing malware-laced spear-phishing emails. It ties that focusing on to previous phishing attempts using malware known as Lookback identified by Proofpoint in 2019. One more group Dragos has dubbed Stibnite has focused Azerbaijani electrical utilities and wind farms utilizing phishing web sites and malicious e-mail attachments, but it surely has not hit the US to the safety agency’s information.

Whereas none among the many ever-growing record of hacker teams focusing on industrial management methods world wide seems to have used these management methods to set off precise disruptive results in 2020, Dragos warns that the sheer variety of these teams represents a disturbing development. Caltagirone factors to a uncommon however comparatively crude intrusion targeting a small water treatment plant in Oldsmar, Florida earlier this month, through which a still-unidentified hacker tried to vastly enhance the degrees of caustic lye within the 15,000-person metropolis’s water. Given the dearth of protections on these types of small infrastructure targets, a bunch like Kamacite, Caltagirone argues, may simply set off widespread, dangerous results even with out the industrial-control-system experience of a accomplice group like Electrum.

Meaning the rise in even comparatively unskilled teams poses an actual risk, Caltagirone says. The variety of teams focusing on industrial management methods has been frequently rising, he provides, ever since Stuxnet showed at the beginning of the last decade that industrial hacking with bodily results is feasible. “Loads of teams are showing, and there usually are not lots going away,” says Caltagirone. “In three to 4 years, I really feel like we’ll attain a peak, and it is going to be an absolute disaster.”
