sides.fr Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The sides.fr Listed by lockbit2 Ransomware Group (reported October 6, 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.
Breaking down the breach
The incident record shows only that sides.fr appeared on the lockbit2 leak site on the reported date. No confirmed count of records, no list of specific file names, and no verified timeline of access or encryption have been published. The sole detail provided is the group’s assertion that internal files were taken. Whether the data was later published, sold, or used for further activity is not stated in the available facts.
Inside lockbit2
LockBit 2.0 is a ransomware-as-a-service operation that has been publicly documented since at least 2020. The group typically supplies encryption tools to affiliate attackers, who then target organizations and exfiltrate data before deploying ransomware. Its operators have maintained a leak site where they list victims and, in some cases, publish samples of claimed stolen material. The group’s listings are presented by the operators themselves and are not independently verified at the time of posting.
Who is sides.fr?
sides.fr is a French organization operating under a .fr domain. Public records do not detail its precise sector or size in the breach notification. Entities with this profile commonly maintain internal administrative, operational, and customer-related records as part of routine business. A claim of access to such an organization’s files therefore raises questions about the handling of whatever data the organization holds, regardless of the organization’s scale.
The information in question
The only data category named in the listing is “internal files.” No further breakdown—such as customer records, financial documents, or employee information—has been released. The exact scope and sensitivity of the material therefore cannot be confirmed from public sources.
- Internal files exfiltrated (per group claim)
- Number of individuals affected: unknown
- Publication status of any files: undisclosed
Why it matters
When internal files are claimed to have been removed from an organization, the practical consequences depend on what those files contain. Individuals whose information appears in such material may face risks of follow-on fraud or targeted scams if the data later circulates. For the organization, the incident adds to the growing set of publicly listed ransomware events, which can affect contractual obligations, regulatory reporting, and future insurance considerations even when the full impact remains unclear.
If your data was in this claimed breach
Begin by monitoring accounts for unusual activity and enabling multi-factor authentication where available. Review any recent password resets or login alerts from services that may share data with sides.fr. Individuals can also run a free exposure scan of their email address against known breach data sets to check whether their information has appeared in other documented incidents.

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.
