high severity June 07, 2024 · 3 min read Unverified claim — what this is

grupoamper.com Listed by blackbasta Ransomware Group

If you are a customer of grupoamper.com, here’s what is being claimed, and what it would mean for you.

grupoamper.com was listed on Blackbasta's leak site. Blackbasta claims to have stolen internal data. This is the group's claim, not a confirmed finding.

grupoamper.com Listed by blackbasta Ransomware Group

On June 7, 2024, Spanish technology company Grupo Amper appeared on the leak site of the Black Basta ransomware group. The listing states that attackers exfiltrated roughly 650 GB of internal files during a ransomware incident. The company, whose roots date back to 1951, provides telecommunications, defense, and technology services from its headquarters in Pozuelo de Alarcón, Madrid. Anyone whose personal or employment records sit inside those files now faces heightened risk of identity theft and targeted fraud.

Details in the Leak Listing

The Black Basta leak site entry for grupoamper.com claims the attackers stole R&D data, projects, and information on users and employees. The disclosure does not quantify how many individuals are affected, nor does it list every file type exposed. It simply states that internal files were taken and gives a total volume of approximately 650 GB. No ransom demand figure or payment deadline appears in the public listing. The notification confirms the data was obtained through a ransomware attack but provides no further technical details about the intrusion method.

Why This Matters for You and Your Family

When a company that supplies government and defense customers loses control of internal files, the consequences reach far beyond the corporate perimeter. Employee names, contact details, project documents, and possibly customer records can give criminals the raw material needed to build convincing phishing campaigns or fraudulent loan applications in your name. If you or a family member have ever worked at Grupo Amper or used its services, your information may now sit in an attacker-controlled archive. Even partial exposure of addresses, phone numbers, or dates of birth increases the chance that scammers will target your household with tailored attacks.

Doxxing and Identity-Chain Risks

Leaked internal files often contain more than isolated records. They can link email addresses to full names, project roles, and sometimes family contact details. Attackers stitch these fragments together with data from other breaches to create persistent identity profiles. A single leaked work email can lead to discovery of personal accounts, social-media handles, and even children’s gaming usernames. Once mapped, these chains enable account takeovers, SIM-swapping, and long-term extortion. Credential leaks of this nature frequently cascade into gaming platforms, where children’s accounts become entry points for further harassment or financial fraud.

Black Basta’s Known Track Record

Public reporting attributes the first Black Basta operations to early 2022. The group has since hit hospitals, manufacturers, and technology firms across multiple continents. Their typical playbook involves gaining initial access through phishing or exploited remote-desktop services, exfiltrating data before deploying ransomware, and then running a double-extortion campaign: they threaten both encryption and public release of stolen files. The Black Basta leak site routinely posts samples and full datasets when victims do not pay. Industry researchers tracking the group note its consistent focus on medium-to-large organizations that handle sensitive technical or personal information.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
  • Rotate any password you ever used at Grupo Amper or related systems, replace it with a unique passphrase, and secure those accounts with an authenticator app for 2FA.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same leaked contact details.
  • Let remediation specialists manage takedown requests for any exposed personal records found on data-broker and extortion sites.

The incident shows once again that a single successful ransomware attack can turn years of corporate data into long-term personal risk. Staying ahead requires more than changing a password. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and over 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with full household coverage that includes children’s gaming accounts. Start your DoxxScan trial today to close the gaps attackers count on.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
