Prasaga Listed by fog Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to dominate the cyber-threat landscape in 2025, routinely combining encryption with data theft and public leak-site listings to pressure victims. Listings appear almost daily, often with limited corroborating detail, leaving organisations and individuals to assess risk from incomplete public claims. Against that backdrop, the appearance of Prasaga on a ransomware leak site on 30 January 2025 is one more data point in an ongoing pattern of opportunistic attacks on technology and blockchain-related firms.

Public reporting indicates that the ransomware group known as fog has listed Prasaga, claiming to have exfiltrated internal files during a ransomware attack. The number of people affected remains unknown, and no independent confirmation of the full scope has been released. The listing matters because any organisation holding internal operational or customer-related material can create downstream risk for partners, employees and users if that material is later published or sold.

Breaking down the breach

According to the available record, Prasaga was listed by the fog ransomware group on 30 January 2025. The report states that internal files were exfiltrated in a ransomware attack. No further technical details—such as the initial access vector, the precise date of intrusion, the volume of data taken, or whether systems were encrypted—have been disclosed in the public summary. The number of individuals potentially affected is listed as unknown. A brief extract associated with the reporting also names Prasaga alongside HE2B and Kombinat, but supplies no additional context about those entities or their connection to the incident. All specifics beyond the claim of internal-file exfiltration therefore remain unconfirmed.

The group behind it: fog

Fog is a ransomware operation that has been active in the public threat landscape since roughly mid-2024. Like many contemporary groups, it typically employs a double-extortion model: encrypting systems while simultaneously stealing data and threatening to publish it on a dedicated leak site if a ransom is not paid. Public analyses of prior fog activity describe the use of common initial-access methods such as compromised credentials or vulnerable remote services, followed by lateral movement and data staging before encryption. The group has listed victims across multiple sectors, including technology, manufacturing and professional services. In the present case the only claim specifically tied to Prasaga is the leak-site listing itself and the assertion that internal files were taken; no further statements from the group about this particular victim have been recorded in the available facts.

About Prasaga

Prasaga is a technology organisation operating in the blockchain and distributed-ledger space. Companies of this type typically develop platforms intended to support decentralised applications, smart contracts or next-generation ledger architectures. As such they commonly hold source code, internal design documents, employee records, partner agreements and, in some cases, limited customer or investor contact information. A breach involving a firm in this sector is consequential because the compromise of proprietary technical material can affect competitive position, while any personal or contractual data that may be present can create secondary risks for individuals and business partners. Public detail on Prasaga’s exact data holdings is limited, so the precise sensitivity of the material claimed to have been taken cannot be independently verified from the breach record alone.

What was likely exposed

The facts name only “internal files” as having been exfiltrated. No inventory of file types, no count of records, and no confirmation of personal data, credentials or financial information have been provided. Organisations working on blockchain platforms typically maintain source-code repositories, internal project documentation, employee directories, vendor contracts and administrative credentials. Whether any of those categories were among the files taken remains unconfirmed. Readers should therefore treat the exact contents as unknown pending further disclosure by the organisation or independent verification.

The real-world impact

For individuals whose information may have been present in the internal files, the primary risks are the usual ones associated with any corporate data exposure: possible phishing that references internal details, credential stuffing if passwords or email addresses were stored, and longer-term identity-related fraud if personal identifiers were included. Because the scale and exact data types are undisclosed, the severity for any given person cannot be quantified. For Prasaga itself the consequences include potential operational disruption, the cost of investigation and remediation, possible regulatory notification obligations depending on jurisdiction, and reputational pressure arising from the public listing. Partners or counterparties named in internal documents could also face secondary targeting if those documents surface. None of these outcomes is guaranteed; they represent the concrete, non-sensational risks that follow from an unverified claim of internal-file exfiltration.

What to do if you're exposed

If you have a past or present relationship with Prasaga—employee, contractor, partner or user—treat the listing as a prompt to take basic precautions. Change any passwords that may have been reused across work and personal accounts, enable multi-factor authentication wherever it is available, and monitor financial and email accounts for unexpected activity. Be sceptical of unsolicited messages that reference internal projects or personal details. Because the precise data involved remain unconfirmed, these steps are precautionary rather than reactive to a verified personal exposure. Readers can also run a free exposure scan of their email address to check whether that address has already appeared in other known breach data sets; such a scan does not confirm involvement in this specific incident but can surface earlier compromises that warrant attention.
