LockBit Claims Breach of U.S. Bank, Sets September 2026 Deadline for Ransom Payment

The ransomware group LockBit has added U.S. Bank to its leak site, claiming to have stolen data from the financial institution and threatening to publish it unless a ransom is paid by September 3, 2026. U.S. Bank stated it is actively investigating the claims but has so far found no evidence of unauthorized network access or impact on internal systems. Lee Henderson, the bank's vice president of public affairs, confirmed that the institution is monitoring the situation and treating the allegations seriously. LockBit placed the bank's domain on its extortion portal on August 19 and has a history of resuming operations after a major international law enforcement disruption in 2024. The investigation remains ongoing, with the final scope depending on whether unauthorized access and data theft can be confirmed.

The ransomware group LockBit has claimed responsibility for breaching U.S. Bank and is threatening to publish stolen data if its extortion demands are not met.

U.S. Bank is currently investigating the allegations made by LockBit, which asserts that it successfully infiltrated the financial institution and exfiltrated sensitive information. As of now, the bank reports that it has not identified any signs of unauthorized access to its network or any adverse effects on its internal systems.

LockBit added the U.S. Bank domain to its dedicated leak site on August 19 and set a payment deadline of September 3, 2026. Should the ransom not be paid by that date, the group has warned it will release the allegedly stolen data.

Lee Henderson, vice president of public affairs at U.S. Bank, confirmed that the organization is aware of the claims and is actively investigating the matter while monitoring for any potential data exposures related to the incident.

LockBit remains one of the most prominent ransomware operations in recent years. Although its infrastructure was significantly disrupted by a coordinated international law enforcement operation in 2024, the group quickly rebuilt and resumed listing victim organizations on its extortion portal.

The investigation is continuing, and the ultimate impact of the case will depend on whether unauthorized access and data compromise can be verified.

Ransomware Group Emperador Claims 3.9 GB Data Theft from AB InBev

The ransomware group Emperador has added AB InBev, the manufacturer of Budweiser and Corona beers, to its list of alleged victims. The group claims to possess 3.9 GB of internal data and is demanding a $1 million Bitcoin ransom. The listing includes 329,244 social listening alerts, 2,510 corporate emails from subsidiaries, around 19,000 access records, internal service portal logs, and public key infrastructure certificates. Most of the data volume, 3.2 GB, is attributed to Azure storage assets. AB InBev has neither confirmed nor denied the claims, and no samples have been published to verify authenticity. The announcement provides no details on how the data was allegedly obtained, such as an exposed storage account or leaked credentials. While access records and certificates could aid network mapping and lateral movement, the lack of private keys or confirmed encryption of systems limits the immediate impact assessment.

Russian Ransomware Groups INC and The Gentlemen Deploy AI-Driven Phantom Framework for Fully Automated Attacks

SOCRadar researchers have disclosed the Phantom framework, an AI-powered autonomous ransomware attack platform operated by members linked to the INC and The Gentlemen groups. The system uses commercial large language models routed through OpenRouter to scan 7,158 edge devices, steal 535 administrator accounts, and compromise 4,140 endpoints. AI agents autonomously generate custom encryption binaries, craft personalized ransom demands based on stolen financial data, and write kernel drivers to disable EDR solutions before encryption. The framework runs on 32 custom MCP servers that give the AI direct access to scanning, credential abuse, financial analysis, and anti-detection tooling. Human operators only supply target prompts and approve final actions while the AI executes the entire kill chain. Phantom Agent v3.1 implants masquerade as Windows Update components and communicate over encrypted channels with randomized polling intervals. The discovery reveals a mature Ransomware-as-a-Service model that lowers the barrier for other criminal groups to conduct large-scale AI-automated extortion.
