Aldes Listed by avaddon Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On September 9, 2021, the ransomware group Avaddon listed Aldes on its data-leak site. The listing indicated that internal files had been taken during a ransomware operation. No confirmed count of affected individuals or specific file inventories has been made public.

The incident reflects a pattern in which ransomware operators combine encryption of systems with the threat of publishing stolen material. Such listings place the burden on the listed organization to confirm or refute the claims while affected parties await clearer information.

Inside the incident

The only confirmed public detail is the appearance of Aldes on Avaddon’s leak site on the reported date. The group stated that internal data had been exfiltrated. No further information on the volume of data, the encryption status of Aldes systems, or any ransom demand has been disclosed.

Timing of the initial intrusion, duration of access, and whether data were published after the listing remain unknown. No independent verification of the claimed theft has been reported.

Who is avaddon?

Avaddon operated as a ransomware group that used an affiliate model in which multiple actors deployed the same encryption tools. Its operators were known for maintaining a public leak site where they listed organizations from which they claimed to have obtained data.

The group’s typical approach involved encrypting victim systems and then threatening to release stolen files if a ransom was not paid. Avaddon ceased visible operations after law-enforcement actions against ransomware infrastructure in mid-2021, though prior listings remain part of the public record of incidents.

Aldes and its sector

Aldes is an organization that maintains internal operational records as part of its normal business activities. Entities of this type routinely store employee information, supplier details, financial records, and technical documentation required for day-to-day functions.

When such an organization appears on a ransomware leak site, the potential exposure of these records raises questions about the security of data held across its sector, even when the precise contents of any exfiltrated material are not yet confirmed.

What was likely exposed

The listing referenced internal files taken during a ransomware attack. The exact categories of information contained in those files have not been disclosed.

Organizations in comparable sectors commonly hold records that include personal identifiers of staff and clients, contractual documents, and system credentials. Without a published inventory, it is not possible to state which of these categories, if any, were present in the material claimed by the group.

Why it matters

Individuals whose information appears in internal files face the possibility that their details could be used for targeted phishing or identity-related fraud if the material is later circulated. The absence of a confirmed data set means the scale of this risk cannot yet be quantified.

For the organization, the listing creates ongoing uncertainty about the integrity of its systems and the potential circulation of its documents, regardless of whether a ransom was paid or data were ultimately published.

If your data was in this claimed breach

Monitor bank and email accounts for unusual activity and consider placing fraud alerts with credit-reporting agencies. Change passwords for any services where the same credentials may have been reused.
