Party Rental LTD Listed by avaddon Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Party Rental LTD Listed by avaddon Ransomware Group (reported September 9, 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 September 09, 2021, Party Rental LTD appeared on a leak site operated by the ransomware group avaddon. The listing indicated that internal files had been taken during a ransomware incident, though the number of people affected and the precise contents of those files remain undisclosed in public reporting.
The appearance of the company on such a site raises practical questions for customers, employees and business partners whose information may have been stored in the affected systems. When internal records are claimed to have been removed, the immediate concern is how that material could be used and what steps might limit further exposure.
Inside the incident
Public information states only that Party Rental LTD was listed on the avaddon ransomware leak site on the reported date. The group claims to have stolen internal data during a ransomware attack, but no confirmed count of records, list of file types or timeline of the intrusion has been released by the company or independent investigators. Details such as the initial access method, duration of access or whether encryption was also deployed are not publicly confirmed.
The group behind it: avaddon
Avaddon operated as a ransomware-as-a-service group that combined file encryption with the threat of data publication. Its operators maintained a leak site where they listed victims and, in some cases, published samples of material they claimed to have taken. The group was publicly active in 2020 and 2021 before its infrastructure was disrupted. When a company appears on the site, the listing itself constitutes the group’s claim of possession; independent verification of the data’s authenticity or completeness is not provided by the actors.
Party Rental LTD and its sector
Party Rental LTD supplies equipment and services for events, requiring coordination with clients, venues and vendors. Organisations in this sector routinely collect names, contact details, addresses, payment information and scheduling records to fulfil orders and manage logistics. A claim that internal files were removed therefore touches both commercial operations and any personal information held in the same systems.
What data was at risk
The only detail released is that internal files were allegedly exfiltrated. The exact categories of data contained in those files have not been disclosed. Companies of this type commonly store customer contact and payment records, employee information and contractual documents; however, whether any of these specific categories were present in the claimed exfiltration cannot be confirmed from available information.
What's at stake
Individuals whose records appear in the exfiltrated material could face risks of targeted fraud or misuse of personal details, depending on what the files actually contained. For the organisation, the incident adds operational costs for investigation, notification and potential regulatory response, even when the full scope of data remains unknown. Both outcomes hinge on information that has not yet been made public.
What to do if you're exposed
Anyone who has done business with Party Rental LTD or worked there can monitor their accounts for unusual activity and consider placing fraud alerts with credit agencies. Changing passwords for any associated services and enabling multi-factor authentication reduces the chance that reused credentials can be exploited.

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.
