Mikro Trading Listed by avaddon Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Mikro Trading 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.
Inside the incident
The only public record is the entry on the Avaddon leak site dated 9 September 2021. The entry asserts that files were removed from Mikro Trading systems. No information has been published about when the intrusion began, how access was obtained, or how many records were involved. The organisation has not issued a statement confirming or denying the listing.
Inside avaddon
Avaddon is a ransomware operation that emerged in 2020 and used a double-extortion model: data were encrypted on victim systems and copies were threatened with publication if a ransom was not paid. The group maintained a public leak site where it listed organisations it claimed to have targeted. Avaddon ceased posting new victims in mid-2021 after infrastructure takedowns and leaks of its own tools. Its listings were presented by the group as evidence of successful operations but were not independently verified at the time they appeared.
Who is Mikro Trading?
Mikro Trading operates as a commercial trading entity. Companies of this type routinely maintain records that include supplier contracts, customer details, pricing information, internal correspondence and financial documentation. A compromise of such records can expose business relationships and operational data that are not normally public.
What was likely exposed
The listing refers only to “internal files.” No inventory of file types, record counts or time periods has been released. Organisations in the trading sector commonly store the following categories of information:
- Customer and supplier contact details
- Contract and pricing documents
- Internal emails and project files
- Financial and accounting records
The precise contents of any exfiltrated material remain unconfirmed.
The real-world impact
Individuals whose information appears in the files face the possibility that their contact details or commercial relationships could be used for targeted phishing or social-engineering attempts. For the organisation, publication of internal documents can reveal negotiating positions, client lists or operational procedures to competitors. No evidence of subsequent misuse of the material has been reported in public sources.
If your data was in this claimed breach
Monitor email accounts associated with Mikro Trading for unusual messages. Enable multi-factor authentication on any accounts that may share passwords with the affected systems. Review bank and credit statements for unauthorised activity. Readers can run a free exposure scan of their email address against known breach data to check whether their information appears in other public listings.

Publicly posted by avaddon — 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.
