The Russian state research center, the Kvant Institute, which specializes in research and technological development of electronic hardware and software for the state and its public institutions, has also been added to the sanctions list.
The move is in response to alleged Russian cyber-attacks on the US.
The Trump administration on Monday slapped sanctions on several Russian companies and businessmen for engaging in cyberattacks and assisting Russia's military and intelligence services with other malicious activities.
Another company listed as having an Israeli address, ERPScan, was also added to the Treasury blacklist, which freezes all USA property belonging to the companies and prohibits United States citizens from doing business with them.
The three sanctioned men are Aleksandr Lvovich Tribun; Oleg Sergeyevich Chirikov; and Vladimir Yakovlevich Kaganskiy; all of whom work for Divetechnoservices. It also said that Russian Federation had been tracking undersea cables that carry the bulk of the world's telecommunications data. It said Divetechnoservices had procured a variety of underwater equipment and diving systems, including a submarine, for Russian government agencies. They all work for Divetechnoservices. Embedi is known for exploit research and security solutions for protecting hardware devices.
"From my opinion it's the only one connection we have with Digital Security".
ERPScan CTO & Founder Alexander Polyakov told Bleeping Computer that ERPScan is a private company in the Netherlands and is not an subsidiary of any company listed in the press release.
The penalties were issued under the Russian sanctions law Congress passed a year ago and a 2015 executive order targeting cybercrime. "It was like a dream to do what you love, like breaking the security of big corporations, and earn money". While the latter two are not based in Russia, the department said they are owned by Russia-based Digital Security, which worked on a project to help Russian hackers.
The attacks also included assaults on the USA energy grid and on internet routers and switches, the Treasury said. "We are a software company focused on helping to protect ERP systems".
