Mutual Screw & Supply Listed by sinobi Ransomware Group

On March 24, 2025, industrial supplier Mutual Screw & Supply appeared on the leak site of the sinobi ransomware group. The company, which distributes screws, nuts, bolts, washers, rivets, safety equipment and related industrial fasteners, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, anyone who has done business with the New Jersey-based distributor since its founding in 1947 could be affected.

Reported Details of the Breach

Public reporting indicates that sinobi listed Mutual Screw & Supply on its dark-web leak portal and began publishing what it claims are stolen internal documents. The data consists primarily of internal files rather than a structured database of customer records. No confirmed total of impacted individuals has been released by the company or the attackers. The listing appeared on March 24, 2025, on the onion address operated by the group and mirrored by ransomware-tracking services such as ransomware.live.

Why This Matters for You and Your Family

When a supplier like Mutual Screw & Supply is breached, the information that surfaces can include invoices, purchase orders, shipping addresses, contact names, phone numbers and email accounts tied to both business and personal orders. If you or anyone in your household has ever bought fasteners, tools or safety gear from them—whether for home repairs, a family business or a child’s school project—those details may now sit in an attacker’s archive. Once exposed, the same email address or phone number is often reused across online shopping, banking and social-media accounts, creating a single point of failure that puts your family’s finances and privacy at risk.

The Doxxing and Identity-Chain Risks

Leaked business files frequently contain enough personal handles, addresses and contact data to start an identity chain. Attackers link an email from one breach to usernames on forums, gaming platforms and social networks, then map those back to real-world identities. Credential leaks of this nature regularly cascade into account takeovers, especially for gaming accounts belonging to you or your children. A single reused password combined with an exposed shipping address can let intruders hijack profiles, demand ransom from friends lists, or publish private information across multiple platforms.

Sinobi Group’s Known Track Record

Public reporting attributes the sinobi ransomware operation to a group that emerged in late 2024. The actors have claimed responsibility for attacks on manufacturing, distribution and professional-services companies. Their typical playbook involves gaining initial access through phishing or exploited remote-desktop services, exfiltrating documents before encrypting systems, and then publishing samples on their leak site when victims refuse to pay. Extortion demands usually combine threats of data release with offers of “proof” that the files are genuine. Exact prior victim counts remain difficult to verify, but trackers list sinobi among the newer entrants in the ransomware-as-a-service ecosystem.
