What Public Reporting Shows
Public reporting indicates that Medusa posted Presort First Class to its dark-web leak portal with proof of the data theft. The compromised material totals 279.30 GB and consists of internal files exfiltrated during a ransomware incident. No exact count of affected individuals has been released, but the volume suggests thousands of customer and employee records are involved. The company’s headquarters at 2621 SE 15th St, Oklahoma City, Oklahoma, 73129, appears in the posted data alongside business contracts, client lists, and internal spreadsheets.
Available reporting describes the leak as part of Medusa’s standard double-extortion tactic: encrypt the victim’s systems, then threaten to publish stolen data unless a ransom is paid. As of the listing date, Presort First Class had not issued a public statement confirming the breach or detailing what specific categories of personal information were taken.
Why This Matters for You and Your Family
If you have used Presort First Class for direct mail, package forwarding, or printed marketing materials, your name, address, phone number, or email may be among the stolen records. That information can be combined with data from earlier breaches to build a detailed profile of your household. Children’s school records, medical forms, or family photos sometimes travel through printing and mailing vendors, placing younger family members in the exposure chain as well.
