Posiflex Listed by Coinbase Cartel Ransomware Group

On March 30, 2026, Posiflex Technology appeared on the leak site of the ransomware group known as coinbasecartel. The company, which makes point-of-sale systems used by retailers, restaurants, hospitals, and other businesses worldwide, may have had internal files stolen during a ransomware attack.

Reported Details of the Breach

Public reporting indicates that coinbasecartel listed Posiflex on its dark-web leak page and began publishing samples of the stolen data. The exposed material consists of internal files exfiltrated during the ransomware incident. The exact number of people whose personal information is contained in those files remains unknown. No confirmed timeline for the initial breach has been released beyond the March 30 listing date. The coinbasecartel leak site, accessible via the onion address fjg4zi4opkxkvdz7mvwp7h6goe4tcby3hhkrz43pht4j3vakhy75znyd.onion, continues to display the Posiflex entry as of the latest available screenshots.

Why This Matters for You and Your Family

When a company like Posiflex is hit, the information stolen is rarely limited to corporate spreadsheets. Customer records, employee details, vendor contacts, and partner information often sit in the same shared drives. If your name, address, email, phone number, or payment history appears in any of those files, it can surface on criminal forums within days. For ordinary families this means higher risk of identity theft, targeted phishing, or sudden spikes in spam and scam calls. Children’s names linked to family addresses can also be swept up, creating long-term privacy headaches that are difficult to untangle alone.

The Doxxing and Identity-Chain Risks

Ransomware groups rarely stop at posting one company’s data. Once initial files appear, opportunistic criminals scrape them for email addresses, usernames, and passwords. These credentials are then tested across dozens of other services. A single leaked work email can unlock personal accounts, social media, and even children’s gaming profiles. The result is an identity chain: one breach links handles to real names, addresses, and family relationships. Public reporting describes this pattern in many recent ransomware cases, where initial corporate leaks cascade into personal doxxing within weeks.

Coinbasecartel’s Known Track Record

Public reporting attributes the coinbasecartel ransomware group with activity that emerged in late 2024. The group has listed multiple organizations on its leak site, typically following the same pattern of gaining initial access, exfiltrating data, encrypting systems, and then demanding payment to prevent publication. Notable prior victims include other mid-sized technology and manufacturing firms. Their playbook relies on double extortion: first locking the victim’s systems, then threatening to release sensitive files unless a ransom is paid by a short deadline. Available reporting describes their leak site as one of several active ransomware portals that update within hours of a new victim being added.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this claimed breach may have exposed about you.
• Rotate any password you used at Posiflex or any related vendor account, then enable two-factor authentication through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak that touches your family is flagged within hours instead of months.
• Cover the entire household with DoxxScan family protection, which includes children’s gaming accounts that often chain back to the same home address or parent email.
• Let remediation specialists handle the follow-up work of sending takedown notices to data brokers and monitoring forums where the Posiflex files may spread.
