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.

Reported Details from the Listing
The LockBit 3.0 leak site entry for cqservice.sk states that the company suffered a ransomware intrusion and that attackers successfully exfiltrated internal files. The disclosure does not specify the volume of data taken, the exact types of records involved, or any ransom demand. It simply states that data was stolen and is now held by the group. The listing does not detail which systems were breached or whether customer databases, employee records, or partner agreements were included. Public reporting on LockBit 3.0 shows that when specific file samples or record counts are omitted, the group often still possesses the full archive and uses the initial posting as leverage for extortion.
Why This Matters for You and Your Family
When an IT services provider like CQ service is hit, the ripple effects reach ordinary people. If you or your family used their hardware, support contracts, cloud services, or consulting between 1992 and the present, your information may sit inside the stolen files. Internal files exfiltrated in ransomware attacks frequently contain contracts, invoices, support tickets, remote-access logs, and contact lists. These records commonly include names, addresses, phone numbers, email accounts, and sometimes payment details. Once exposed, this data fuels identity theft, phishing campaigns, and long-term fraud against you and your household.
The Doxxing and Identity-Chain Risk
Stolen internal files rarely stay isolated. Attackers and subsequent buyers map email addresses to usernames, link support tickets to home addresses, and connect phone numbers to family members. A single leaked support ticket can expose your child’s gaming username if it was ever mentioned during a household IT issue. These connections create doxxing chains that let criminals target you across social media, gaming platforms, and financial accounts. Credential leaks of this nature frequently cascade into account takeovers precisely because the same password used for an old CQ service portal may still protect your email, banking, or your children’s Roblox or Minecraft accounts.
