A listing of this kind is an assertion made by the group during an extortion attempt. It is not evidence that a breach occurred, and we report it as a claim rather than as a finding.

On May 30, 2024, Illinois-based fastener manufacturer Sems and Specials appeared on the leak site operated by the Medusa ransomware group. The company, founded in 1990 and located at 6483 Falcon Rd, Rockford, Illinois, had 122.13 GB of internal files exfiltrated during a ransomware attack. The disclosure does not specify the exact number of people whose information may have been exposed.
Details in the Leak-Site Listing
The Medusa leak site states that Sems and Specials suffered a ransomware attack in which attackers exfiltrated internal files before encrypting systems. The listing explicitly notes 122.13 GB of data and provides a sample of the stolen material. No customer records count or specific data categories such as names, Social Security numbers, or payment details are detailed in the posting. The disclosure indicates the data was taken from the company’s corporate network and is now hosted for anyone who visits the onion site.
Why This Matters for You and Your Family
When a manufacturing supplier like Sems and Specials loses control of internal files, the information often includes employee records, vendor contracts, and correspondence that can contain personal details of ordinary workers and their families. If your employer, your spouse’s employer, or a company you do business with uses Sems and Specials, your contact information, address, or employment history may now sit in a publicly accessible ransomware repository. Internal files exfiltrated in ransomware attack frequently hold spreadsheets that list home addresses, dates of birth, and sometimes direct-deposit routing data—exactly the building blocks identity thieves need.

The Doxxing and Identity-Chain Risk
Stolen internal documents rarely stay isolated. Attackers and opportunistic criminals cross-reference employee names, email addresses, and phone numbers found in the 122.13 GB dump with other breaches. A single work email from the Sems and Specials leak can link your professional identity to personal accounts on shopping sites, streaming services, and children’s gaming platforms. Once those connections are mapped, credential-stuffing attacks become trivial. Gaming accounts belonging to you or your children are especially vulnerable because kids often reuse simple passwords tied to a family email address that may now be exposed. The result is a cascading doxxing chain that can expose your home address, family relationships, and financial habits.
Medusa’s Known Track Record
Public reporting attributes Medusa’s first major campaigns to late 2021. The group has since hit hospitals, manufacturers, and local governments across the United States and Europe. Their typical playbook begins with phishing or exploitation of remote-desktop services to gain initial access, followed by exfiltration of sensitive files and deployment of ransomware that encrypts remaining data. Medusa then posts victim names and data samples on their leak site, pressuring payment by threatening to release the full archive. The Sems and Specials listing follows this exact pattern, claiming the group’s continued focus on mid-sized industrial companies whose internal files contain employee and operational data.
