— from Blackbasta’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
swisspro.ch Listed by blackbasta Ransomware Group

On April 19, 2024, Swiss engineering and ICT services provider swisspro.ch appeared on the leak site operated by the Black Basta ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the company, which employs roughly 1,000 specialists across 20 locations in Switzerland and provides electrical installation, automation, and ICT solutions to businesses of all sizes. The number of people whose data may have been exposed remains unknown, and the leak-site listing does not detail the specific files or record types taken.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Reported Details from the Listing

The Black Basta leak page for swisspro.ch states that the company suffered a ransomware intrusion in which attackers successfully exfiltrated internal files before encrypting systems. No victim count, ransom amount, or exact data categories are published on the site. The disclosure consists primarily of the company name, its Swiss address, a brief description of its services, and screenshots or samples that Black Basta chose to publish as proof. As is typical with this group’s playbook, the listing serves as both evidence of compromise and a public shaming mechanism intended to pressure the victim into payment.

Why This Matters for You and Your Family

If you or any member of your household has worked with swisspro.ch as a customer, supplier, employee, or job applicant, your personal or business information may now sit in an attacker-controlled archive. Internal files from an ICT and automation provider frequently contain contracts, invoices, employee contact details, project specifications, and correspondence that can be pieced together to map identities, financial relationships, and physical locations. Even when the exact volume of stolen data is not disclosed, the mere fact that internal documents left the corporate network creates long-term exposure for anyone whose details appear inside them.

The Doxxing and Identity-Chain Risk

Stolen internal files often act as the first link in a doxxing chain. An email address found in a swisspro.ch project folder can be cross-referenced with credential leaks from other breaches, revealing passwords reused across personal accounts. Those credentials then unlock social-media profiles, gaming logins, or cloud storage that contain family photos, children’s names, and home addresses. Once attackers or opportunistic criminals connect these dots, targeted harassment, identity theft, or follow-on extortion becomes straightforward. Credential leaks like this one frequently cascade into account takeovers precisely because companies in the ICT sector handle credentials and network diagrams that point straight back to individuals and their families.

Black Basta’s Known Track Record

Public reporting attributes the Black Basta ransomware group’s first significant appearances to early 2022. Since then the group has compromised hundreds of organizations across North America, Europe, and Australia. Notable prior victims include large manufacturers, healthcare providers, and professional-services firms. Their typical playbook begins with initial access gained through phishing, remote-desktop compromise, or stolen credentials, followed by rapid lateral movement, data exfiltration, and deployment of ransomware that also wipes event logs to hinder recovery. Black Basta usually demands payment in Bitcoin and maintains dual leak-and-encrypt pressure: if the victim does not pay by the stated deadline, additional batches of stolen data are released on their Tor site. The group has shown operational discipline and regularly updates its tooling, making it one of the more persistent extortion operations currently active.

What to do

  • Run a DoxxScan to map every link between your email addresses, phone numbers, usernames, and real-world identity so you can see exactly what swisspro.ch data may have already surfaced elsewhere.
  • Rotate any password you ever used at swisspro.ch or on systems it managed, and enable 2FA through an authenticator app rather than SMS wherever possible.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears in a fresh leak it is flagged within hours instead of months.
  • Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become targets when corporate credential leaks create doxxing chains back to the same home address.
  • Let DoxxScan remediation specialists handle data-broker takedown requests and removal of any exposed personal records on your behalf.

The swisspro.ch incident is a reminder that even well-established Swiss service companies can fall victim to disciplined ransomware operators, and the data they hold about ordinary customers and employees can fuel identity crimes long after the initial breach fades from headlines. Start your DoxxScan trial today; its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage give you and your family a practical way to reduce the harm from leaks like this one before criminals turn stolen files into real-world damage.

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.
