lemonastere.ca Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The lemonastere.ca Listed by lockbit2 Ransomware Group (reported September 10, 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 public record is the appearance of lemonastere.ca on the lockbit2 leak site on the reported date. The group claims to have stolen internal data, but provides no further detail on the method of access, the duration of any intrusion, or the quantity of material removed. The number of individuals whose information may be involved is listed as unknown.
Who is lockbit2?
Lockbit2 refers to a ransomware operation that has been active since at least 2019. The group supplies encryption tools to affiliate actors who target organisations, then posts selected files on a dedicated leak site when ransom demands are not met. Public reporting has linked the operation to incidents across multiple countries and sectors, with a consistent pattern of data exfiltration followed by public listings.
About lemonastere.ca
lemonastere.ca is a Canadian domain. Organisations operating under .ca addresses commonly maintain records that include contact details, account credentials, and administrative documents. A breach at such an entity can therefore involve information that individuals have supplied in the course of ordinary dealings with the site.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types or data categories has been published. Organisations of this kind routinely hold names, addresses, email addresses, and internal correspondence; however, the exact contents of the material claimed to have been taken remain unconfirmed.
What's at stake
Exposure of internal files can lead to follow-on contact from unknown parties, attempts to reuse credentials on other services, or the circulation of documents that were not intended for public view. For the organisation, the incident adds the task of assessing what was removed and notifying any individuals whose information may be affected under applicable Canadian privacy requirements.
If your data was in this claimed breach
Individuals can begin by changing passwords on any accounts associated with lemonastere.ca and enabling multi-factor authentication where available. Monitoring bank and credit statements for unusual activity provides an early indication of misuse. A free exposure scan of an email address against known breach data sets can show whether the address has appeared in previously published collections.

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.
