The examples span actions in 2018, 2021 and 2022; they are not a complete list, and the relationship Treasury described differs by company.

| Company | Treasury-described relationship or activity | Action |
|---|---|---|
| Digital Security | Treasury said the company provided material and technological support to the FSB. | Designated in April 2018. U.S. Department of the Treasury, 2018 |

| Divetechnoservices | Treasury said the company procured underwater equipment for Russian government agencies, including the FSB. The release described a 2011 contract to procure a submersible craft for the FSB valued at $1.5 million; this was the value of that contract, not an overall sanctions amount. | Designated in April 2018. U.S. Department of the Treasury, 2018 |

| Echelon Union for Science and Development | Treasury described Echelon as an information-security systems integrator licensed by the FSB and other Russian authorities. | Named in a broad Russia technology-sector sanctions action in September 2022. U.S. Department of the Treasury, 2022 |

What “linked to the FSB” means in these cases
The phrase covers materially different claims. In 2018, Treasury described support to the FSB, ownership or supervision, and procurement for government agencies. Its 2021 announcement focused on research, technical support and other activity it said supported Russian intelligence services’ cyber operations. The 2022 release described licensing relationships in the context of a broad technology-sector action. Holding a license is not the same factual allegation as conducting operational cyber support.
These announcements should not be read as one uniform accusation or as a ranking of company threat levels. They also do not establish a total number of Russian companies linked to the FSB; Treasury’s cited examples are selected, not exhaustive.

What a U.S. blocking designation generally does
Treasury says that when a person is designated under the relevant blocking authorities, that person’s property and interests in property subject to U.S. jurisdiction are blocked. U.S. persons are generally prohibited from transactions with designated persons. Exemptions and OFAC licenses may apply, so a specific transaction requires checking the applicable rules and authorizations rather than relying on this general description. Treasury’s 2018 announcement and 2021 announcement describe these effects.
The 2021 announcement also explains OFAC’s 50 Percent Rule: an entity owned, directly or indirectly, 50 percent or more by one or more blocked persons is itself blocked, even if it is not separately named on the SDN List. Ownership screening therefore matters in addition to checking an entity’s exact name. Treasury, 2021
Entity-specific claims are not the same as sector sanctions
OFAC explains that Executive Order 14024 permits sanctions on persons determined to operate or have operated in specified sectors of the Russian economy. As of January 10, 2025, OFAC FAQ 1126 listed technology, defense and related materiel, financial services, aerospace, electronics, marine, accounting, trust and corporate formation services, management consulting, and quantum computing. This sector authority is distinct from the specific FSB relationships Treasury described for individual companies. See OFAC FAQ 1126 for the sector framework and consult current OFAC guidance for later changes.
Check current status before relying on an old announcement
A historical Treasury announcement establishes that an action was announced at that time; it does not establish whether a company remains listed today. Before a payment, contract or other compliance decision, search current OFAC data for the exact entity and relevant aliases, check ownership and applicable licenses or exemptions, and consult qualified sanctions counsel when needed. The practical result depends on current list data and the facts of the proposed transaction.

Related FSB cyber action
In 2023, Treasury described an FSB unit associated with tailored spear-phishing activity known by names including Callisto, Seaborgium and Star Blizzard, and designated two individuals associated with the group. That action provides context for Treasury’s stated concerns about FSB cyber activity; it was not the company-designation action and is not evidence about the companies above. U.S. Department of the Treasury, 2023
