Summary

Note: This joint Cybersecurity Advisory is part of an ongoing #StopRansomware effort to publish advisories for network defenders that detail various ransomware variants and ransomware threat actors. These #StopRansomware advisories include recently and historically observed tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) to help organizations protect against ransomware. Visit stopransomware.gov to see all #StopRansomware advisories and to learn more about other ransomware threats and no-cost resources.

The Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), Department of Health and Human Services (HHS), and Multi-State Information Sharing and Analysis Center (MS-ISAC)—hereafter referred to as “the authoring organizations”—are releasing this joint advisory to disseminate known Interlock ransomware IOCs and TTPs identified through FBI investigations (as recently as June 2025) and trusted third-party reporting.

The Interlock ransomware variant was first observed in late September 2024, targeting various business, critical infrastructure, and other organizations in North America and Europe. FBI maintains these actors target their victims based on opportunity, and their activity is financially motivated. FBI is aware of Interlock ransomware encryptors designed for both Windows and Linux operating systems; these encryptors have been observed encrypting virtual machines (VMs) across both operating systems. FBI observed actors obtaining initial access via drive-by download from compromised legitimate websites, which is an uncommon method among ransomware groups. Actors were also observed using

In-brief analysis

July 21, 2025

In 2024, France increased its cross-border electricity deliveries by 48%, from 70 terawatthours (TWh) in 2023 to 103 TWh in 2024. France’s electricity exports to Belgium and Germany increased the most, but France also exported more electricity to Spain, Switzerland, the United Kingdom, and Italy, according to data from the European Network of Transmission System Operators for Electricity. Within France’s electricity generation mix, nuclear energy increased the most, followed by hydropower.

Overall, electricity generation in France increased by 45 TWh in 2024, while consumption remained relatively steady. Nuclear energy generation increased the most, followed by hydropower, while wind and natural gas-fired generation decreased.

The rise in French electricity generation reduced the country’s need for gross electricity imports, which fell by 50% in 2024. Among the six countries France imported electricity from

Data source: U.S. Energy Information Administration, Annual Energy Outlook 2025 (AEO2025)

In our recently published Annual Energy Outlook 2025 (AEO2025), we introduce our new Carbon Capture, Allocation, Transportation, and Sequestration module (CCATS), which allows us to model carbon capture in the coming decades.

The CCATS module allocates projected supply of captured CO2 across the energy system for either enhanced oil recovery or geologic storage using a network representation of capture facilities, transshipment points, and sequestration sites.

In AEO2025, we project CO2 capture at electric power and industrial facilities will increase through the 2030s, primarily due to increased tax credit values. Captured emissions peak at 1.5%–3.5% of energy emissions in the late 2030s in most cases.

In most of our cases, we considered laws and regulations in place as
