sete.co.uk Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The sete.co.uk Listed by lockbit2 Ransomware Group (reported September 23, 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.
On 23 September 2021, the domain sete.co.uk was listed on a site operated by the LockBit2 ransomware group. The entry states that internal files were taken from the organisation, though no further details about volume, contents or confirmation of the theft have been made public.
Such listings form part of a pattern in which ransomware operators publish victim names to pressure organisations into paying. The absence of additional verified information leaves the practical impact on individuals or the business itself difficult to assess from open sources alone.
What happened
The only confirmed public record is the appearance of sete.co.uk on the LockBit2 leak site on the reported date. The group claims to have stolen internal data during a ransomware attack, but the organisation has not issued a statement and independent verification of the claim is not available. The number of people potentially affected and the method of initial access remain undisclosed.
Who is lockbit2?
LockBit2 refers to a ransomware operation that has been active since at least 2019 and functions on a ransomware-as-a-service model. Affiliates deploy the malware, encrypt systems and, in many cases, exfiltrate data before demanding payment. The group maintains a public leak site where it lists organisations that have not paid, presenting this as evidence of stolen material. Its tactics and infrastructure have been documented in multiple law-enforcement and security-industry reports.
Who is sete.co.uk?
sete.co.uk is a United Kingdom organisation registered under a .co.uk domain. Entities of this type routinely store internal operational records, communications and administrative data necessary to their activities. A successful intrusion resulting in data removal therefore carries implications for both the continuity of the organisation and any individuals whose information appears in those records.
The information in question
The listing refers only to “internal files.” No inventory of file types, no indication of whether personal data is included, and no statement on the number of records have been released. Organisations in this category commonly retain employee details, financial documents and client correspondence, yet the precise contents of the exfiltrated material cannot be confirmed from the information currently available.
What's at stake
Exposure of internal files can lead to follow-on risks such as misuse of credentials, targeted fraud or reputational harm to the organisation. Individuals named in the data may face increased likelihood of phishing or account takeover attempts. The organisation itself may incur costs related to investigation, remediation and any regulatory notifications required under UK data-protection rules.
Were you affected?
Individuals who have interacted with sete.co.uk can begin by contacting the organisation directly for any official notification. Running a free exposure scan of an email address against known breach datasets provides an additional check for whether associated information has appeared in previously published collections. Monitoring financial and email accounts for unusual activity remains a prudent step while further details are awaited.

Publicly posted by lockbit — 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.
