4murs.com Listed by babuk Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The 4murs.com Listed by babuk Ransomware Group (reported June 15, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
Inside the incident
The only confirmed detail is the listing itself. The group posted 4murs.com under the heading “The Babuk v2.0 new,” claiming that files had been removed from the organisation’s systems. No date of intrusion, volume of data, or description of the encryption stage has been released by either the group or the company. Public records contain no statement from 4murs.com acknowledging or disputing the claim.
Who is babuk?
Babuk is a ransomware operator that emerged in early 2021 and became known for encrypting files on targeted networks and threatening to publish stolen material if a ransom was not paid. The group maintained a leak site where it listed victims and, in some cases, published samples of data. Its activity was documented by multiple security researchers before the core infrastructure went offline later in 2021. Any specific assertion about 4murs.com originates solely from the group’s own listing and has not been independently verified.
4murs.com and its sector
4murs.com operates in the residential construction and home-improvement sector, a field that routinely maintains records on customers, suppliers, project specifications and internal business operations. Organisations of this type commonly store contact details, financial information related to contracts, and technical documents describing building plans or client requirements. A compromise in this sector can therefore expose both personal and commercially sensitive material even when the exact contents remain undisclosed.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, record counts, or data categories has been published. In the absence of a confirmed list, it is not possible to state which specific records were taken. Typical holdings for a firm in this sector include customer names, addresses, contract details and project documentation, but whether any of these were among the files cannot be confirmed from available information.
Why it matters
Even without a published count of affected individuals, the exposure of internal files can create downstream risks such as misuse of personal contact information or insight into private construction projects. For the organisation, the incident adds operational disruption and potential regulatory scrutiny under data-protection rules that apply to customer records. The lack of disclosed detail leaves those possibly named in the files without a clear picture of their exposure.
What to do if you're exposed
Individuals who have done business with 4murs.com or who suspect their information may be involved should monitor bank and credit accounts for unusual activity and consider placing fraud alerts with credit bureaus. Changing passwords for any associated online accounts and enabling multi-factor authentication reduces the chance of follow-on misuse.

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.
