About Main Electric Supply Co.
Main Electric Supply Co. is a US wholesale distributor of electrical products, supplies and equipment, serving electrical contractors and industrial and commercial customers. A Los Angeles-area distributor, it stocks and supplies wiring, fixtures, gear and related electrical materials through branch locations.
Why They Hold Your Data
As a B2B electrical distributor, Main Electric holds customer trade-account and employee records including names, business contact details and order information collected through account setup and fulfillment; its customer base is primarily contractors and commercial accounts rather than the general public.
Recent Developments
The Sinobi ransomware group claimed Main Electric Supply around August 8, 2025 (intrusion discovered in late July 2025) and threatened to release data. Sinobi is a closed RaaS assessed as an offshoot of the Lynx/INC operations, often gaining access via compromised SonicWall SSL VPN credentials.

Full Name
Breach Impact
A distributor breach primarily exposes trade-account customers and employees, creating notification obligations and business-impersonation risk toward the contractors that rely on Main Electric. The Sinobi extortion listing raises the likelihood of data release if the ransom is unpaid.
Principal Risk Advisory
What this means for a principal
A consumer-service breach: contact and account data supports phishing, account takeover and profile enrichment. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.
What You Should Do
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping: cross-reference the exposed identifiers against broker-available data to size and prioritize the principal's wider footprint.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
