On July 22, 2025, Main Electric Supply Company of Los Angeles appeared on the leak site of the sinobi ransomware group, with attackers claiming to have exfiltrated internal files following a ransomware incident. The company, which has served the electrical industry since 1946, now joins a growing list of small and mid-sized businesses whose customer, vendor, and operational data sit exposed on dark-web forums. Anyone whose name, address, phone number, email, or payment details appear in those files could face identity theft, phishing, or doxxing attempts.

What Public Reporting Shows
Public reporting indicates the sinobi group posted Main Electric Supply Company to its leak site on July 22, 2025. The listing states that internal files were exfiltrated during a ransomware attack, although the exact volume and specific types of records have not been independently verified. The company’s own history page notes it was founded on October 14, 1946 by Charles Vowels and Burt McCombs and built its reputation serving contractors and homeowners across the Los Angeles area. No official statement from Main Electric Supply confirming the breach timeline or notifying customers had been published at the time of this writing.
Why This Matters for You and Your Family
When a local supplier like Main Electric is hit, the data exposed often includes names, billing addresses, phone numbers, email addresses, and sometimes payment records of everyday customers. That information travels quickly once posted on a ransomware leak site. Criminals combine it with other leaks to build profiles that lead to targeted scams, account takeovers, or harassment. Your family does not need to be a high-profile target; simply having done business with the company can place you in the chain. Children’s names or school-related orders sometimes appear in supplier records, giving attackers additional avenues for social engineering.
The Doxxing and Identity-Chain Implications
Ransomware leaks rarely stop at one company. A single exposed email or phone number can be cross-referenced against gaming accounts, social-media handles, and family-member records. This creates an identity chain that links your online activity to your real-world address. Public reporting shows these chains frequently lead to doxxing, SIM-swapping attempts, or extortion demands. Credential leaks of this nature also cascade into gaming account takeovers, especially for households where children use the same email addresses or passwords for Roblox, Fortnite, or other platforms. Once an attacker controls a child’s gaming account tied to a family address, further personal details can be extracted and sold.
