Advance Tapes International Listed by medusa Ransomware Group

On March 21, 2025, Advance Tapes International, a UK manufacturer of specialist adhesive tapes, appeared on the Medusa ransomware group’s leak site with 128.70 GB of internal files listed for public download.

Reported Details of the Breach

Public reporting indicates the company, founded in 1964 and based at Westmoreland Avenue, Thurmaston LE4 8PH, was hit by a ransomware attack. The attackers exfiltrated 128.70 GB of corporate data before encrypting systems. No confirmed list of affected individuals has been published, but the volume suggests the files likely contain employee records, supplier contracts, customer information, and internal correspondence. The Medusa leak page remains active, and the data has been made available to anyone who visits the group’s onion site.

Why This Matters for You and Your Family

When a company like Advance Tapes International loses control of 128.70 GB of internal files, the information often includes personal details that can be used against ordinary people. Employees, contractors, customers, and even their families can find their names, addresses, phone numbers, email accounts, or dates of birth exposed. Once that data reaches criminal marketplaces, it rarely disappears. You and your family become easier targets for phishing, identity theft, and harassment that can continue for years.

Credential leaks from such incidents frequently cascade into account takeovers. If an email address and password pair from this claimed breach matches one you reuse elsewhere, attackers can seize your banking, email, or social media accounts. The same risk applies to your children’s gaming accounts, where stolen credentials often lead to doxxing and further targeting of the household.

The Doxxing and Identity-Chain Risks

Ransomware operators rarely stop at dumping raw files. They or subsequent buyers map relationships between leaked emails, usernames, phone numbers, and real-world identities. A single handle from an employee directory can link to a personal social profile, a child’s gaming username, and a home address. This identity-chain process turns one breach into a persistent threat. Public reporting shows that data from similar incidents has been used to harass families, impersonate victims, and launch follow-on extortion campaigns.

Medusa Ransomware Group’s Track Record

Public reporting attributes the attack to the Medusa ransomware group. The group emerged in 2021 and has since targeted organisations across multiple countries. Notable prior victims include healthcare providers, manufacturers, and local government entities. Their typical playbook involves gaining initial access through phishing or exploited vulnerabilities, exfiltrating data before encryption, and then publishing samples on their leak site if the ransom is not paid. They combine technical extortion with public shaming, often setting short deadlines for payment before releasing larger portions of the stolen data.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real identity so you can see exactly what this claimed breach connects to.
• Rotate any password used at Advance Tapes International or related services anywhere it has been reused, and switch on two-factor authentication through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your information is caught within hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become entry points for doxxing chains after credential leaks like this one.
• Let remediation specialists handle takedown requests across data brokers and leak sites while you focus on securing your own accounts.
