On February 06, 2024, German event-technology provider BTL Veranstaltungstechnik GmbH (www.btl.info) appeared on the leak site of the Black Basta ransomware group. The listing states that internal files were exfiltrated during a ransomware attack; the exact number of records affected and the specific data types contained in those files remain unknown.
Already exposed?
You can’t unleak data. You can take away what it’s worth.
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 580 companies.

Primary Disclosure Details
The Black Basta leak site entry for btl.info states that the company suffered a ransomware intrusion and that attackers successfully removed internal files before encryption. The disclosure does not quantify the volume of data taken, list specific file categories, or reveal any sample documents. It simply marks the victim as “published” on 6 February 2024 and provides the company’s physical address in Düsseldorf together with contact details that match BTL’s public website. No ransom demand figure or payment deadline is shown on the listing itself.
Why This Matters for You and Your Family
When a company that supplies technical production for events, trade shows, and conferences is breached, the stolen internal files can easily contain contracts, invoices, staff rosters, or client contact lists. If your name, email, phone number, or address appears in any of those documents, the exposure may now be public. Black Basta routinely posts proof-of-compromise data openly, which means anyone — including identity thieves and stalkers — can download and search it. For ordinary people this translates into immediate risks of phishing, account takeover, and unwanted physical exposure tied to events you may have attended or helped organise.
Doxxing and Identity-Chain Risks
Internal files from an event-technology firm frequently link personal details to project codes, equipment manifests, or crew schedules. Those fragments become building blocks in larger doxxing chains: an email address found here can be matched with a username from a past conference registration, a phone number from a vendor list, and a home address from an insurance form. Once connected, attackers can hijack accounts, impersonate you to organisers, or target your family. Credential leaks of this nature also cascade into gaming platforms; children’s accounts that reuse an email or password exposed in the BTL files are especially vulnerable to takeover and subsequent harassment.
