In-depth analysis

July 29, 2025

In our Annual Energy Outlook 2025 (AEO2025), we project regional differences in natural gas markets will encourage increased natural gas flows from the mid-Atlantic to the southern Gulf Coast in the coming decades. Across the cases we explored, we project production from the Appalachian Basin in the mid-Atlantic and Ohio region will increasingly meet growing demand on the Gulf Coast in the South Central region, driven largely by increasing liquefied natural gas (LNG) exports. The economics of increased production in the Appalachian Basin are more favorable by 2030, and our model shows natural gas transiting through the Eastern Midwest region on the way to the Gulf Coast.

We froze assumptions for AEO2025 in December 2024, and we did not include market changes, recently passed legislation, regulations, executive actions, or court rulings after

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
