prommgroup.com Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
prommgroup.com was listed by the LockBit5 ransomware group on December 25, 2025, following the exfiltration of internal files. Individuals who may have shared data with the organization should review any notifications they receive and change passwords or enable multi-factor authentication where applicable.
What happened
On December 25, 2025, the ransomware group lockbit5 listed prommgroup.com on its leak site. The listing states that internal files were exfiltrated during a ransomware attack. No further details on the timing of the intrusion, the volume of data taken, or the method of access have been made public. The number of people affected is also undisclosed.
Who is lockbit5?
Lockbit5 is one of several iterations of the LockBit ransomware operation, a group that has conducted numerous attacks since 2019. The group typically uses ransomware to encrypt systems and then threatens to release stolen data if a ransom is not paid. Its activities are documented across multiple public incident reports and law-enforcement advisories. In this case the group claims responsibility for the prommgroup.com incident through its leak-site listing; that claim has not been independently verified in the available information.
About prommgroup.com
PROMM GROUP is a diversified company that began as Prommaharaj Land Development. Organisations in this sector commonly manage property records, client contracts, financial documentation and employee information. A compromise at such a firm can therefore involve data that extends beyond corporate systems into records that identify individuals or detail their financial or property dealings.
What data was at risk
The only confirmed description is that internal files were allegedly exfiltrated. The precise categories of data within those files have not been disclosed. Companies of this type routinely hold personal identifiers, contact details, financial information and property-related records, but it is not confirmed whether any of these specific types were present in the taken material.
The real-world impact
Until the contents of the exfiltrated files are clarified, the concrete risks to individuals cannot be quantified. If personal or financial details are later published, affected people could face increased chances of identity misuse or targeted fraud. For the organisation, the incident adds operational disruption and potential regulatory scrutiny, though the extent of either remains unknown.
What to do if you're exposed
Individuals can begin by monitoring their financial accounts and credit reports for unusual activity. Changing passwords for any accounts linked to prommgroup.com and enabling multi-factor authentication where available are standard next steps. Readers may also run a free exposure scan of their email address against known breach data to check whether their information appears in public listings.

Publicly posted by lockbit5 — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
