hear##### Listed by clop Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 24 December 2024, the ransomware group known as clop publicly listed hear##### on its leak site, claiming to hold internal files taken in a ransomware attack. For anyone whose personal or professional details may sit inside those files, the practical stakes are immediate: the possibility that private correspondence, business records or other sensitive material could be published, sold or used for further fraud.

Public detail remains limited. The number of people affected is unknown, and the precise contents of the files have not been independently confirmed. What is known is that the group asserts it has already exfiltrated data and is contacting organisations that use certain file-transfer software.

Inside the incident

According to the listing posted by clop, hear##### is a presumed victim. The group’s announcement states that it has data belonging to many companies that use Cleo software and that its teams are reaching out to those companies with a “special secret chat.” The only data type named in connection with the incident is “internal files exfiltrated in a ransomware attack.” No file counts, no specific dates of intrusion, and no confirmation of encryption or ransom demands have been disclosed in the available record. The listing itself is a claim by the group; it has not been independently verified as of the reported date of 24 December 2024.

Inside clop

Clop (also styled CL0P or Cl0p) is a well-documented ransomware operation that has operated for several years. The group typically gains initial access through exploited vulnerabilities in widely used enterprise software, then exfiltrates large volumes of data before encrypting systems and threatening public release. It maintains a dark-web leak site where it names victims and, if unpaid, posts samples or full archives. Clop has previously targeted organisations across multiple sectors by abusing flaws in managed file-transfer products, including those associated with Cleo. Its public statements are promotional and coercive; they should be treated as unverified claims until corroborated by the affected organisation or independent investigators.

hear##### and its sector

hear##### is identified in the listing as Hearst Communications, a major media and information company. Organisations of this type typically hold large volumes of internal business records, employee data, subscriber or customer information, editorial material, and commercial contracts. A breach involving such an entity is consequential because media companies sit at the intersection of personal privacy, commercial confidentiality and public information flows. Any unauthorised release of internal files can affect employees, freelancers, business partners and, potentially, individuals whose personal details appear in corporate systems.

The information in question

The only data type explicitly named is internal files said to have been exfiltrated during a ransomware attack. Exact contents remain unconfirmed. Organisations in the media and communications sector commonly store employee records, financial documents, contracts, correspondence and operational data. Whether any of those categories are present in the material claimed by clop has not been verified. Public detail on the precise nature or volume of the files is limited.

What's at stake

For individuals whose information may be among the files, the concrete risks include identity fraud, targeted phishing, and unwanted exposure of personal or professional details. For the organisation, the risks include operational disruption, regulatory scrutiny, reputational harm and potential legal obligations to notify affected parties. Because the scale of the incident and the exact data types remain undisclosed, the full extent of harm cannot yet be measured.

• Possible publication or sale of internal documents
• Increased phishing or social-engineering attempts against staff and contacts
• Regulatory and notification duties if personal data is confirmed present
• Long-term uncertainty until independent verification occurs

Were you affected?

If you have a past or present relationship with hear#####—as an employee, contractor, customer or partner—monitor financial and email accounts for unusual activity and treat unsolicited messages that reference the company with caution. Change passwords on any accounts that may have been linked to corporate systems, and enable multi-factor authentication where available. Readers can also run a free exposure scan of their email address to check whether their information has already appeared in known breach data sets. Official confirmation from the organisation itself remains the most reliable source of further detail.
