On February 13, 2026, the ransomware group thegentlemen listed Yash Highvoltage Insulators Pvt on its leak site, stating that internal files had been taken during a ransomware operation against the company.

Incidents of this type continue to affect manufacturers that support critical infrastructure, where operational data and partner information can carry consequences beyond the immediate victim organisation.
What happened
The listing appeared on February 13, 2026. The group stated that internal files were exfiltrated during a ransomware attack. No information has been released on the date of the intrusion, the duration of access, the quantity of data taken, or whether encryption was also deployed. The organisation has not issued a public statement confirming or disputing the claim.
Inside thegentlemen
Thegentlemen is a ransomware operator that follows the common pattern of encrypting systems and removing data before publishing samples on a dedicated leak site. Groups of this kind typically contact the victim first with a ransom demand and, if payment is not received within their chosen timeframe, begin releasing file listings or samples to increase pressure. Public records show similar actors targeting industrial and manufacturing entities in multiple countries, though the specific tactics used against any single victim are rarely confirmed beyond the initial listing.
Yash Highvoltage Insulators Pvt and its sector
Yash Highvoltage Insulators Pvt is an Indian company that produces transformer bushings for power generation and transmission. Its products are installed in utilities and industrial facilities, with the company reporting more than 40,000 units in service worldwide. Organisations in this sector routinely maintain records on product specifications, client projects, supply-chain arrangements, and internal engineering documentation.
A breach at a supplier to the power sector draws attention because the data held can include details on equipment configurations and customer relationships that extend beyond the company itself.
What was likely exposed
The only category named in the listing is internal files. The precise contents of those files have not been disclosed. Companies of this type commonly store customer contact information, project documentation, technical drawings, financial records, and correspondence with utilities and industrial clients. Without an official inventory or confirmation from the organisation, the exact data elements cannot be verified.
Why it matters
Individuals whose information appears in the exfiltrated files may face increased risk of targeted phishing or misuse of contact details. For the company and its clients, exposure of engineering or contractual material can affect competitive positions and ongoing projects even when personal data volumes remain modest. Because the scale of the incident is still unknown, the full range of downstream effects cannot yet be measured.
What to do if you're exposed
Monitor email accounts associated with the organisation for unusual login attempts or unsolicited messages. Enable multi-factor authentication on any accounts that may have been referenced in company records. Review bank and credit statements for unauthorised activity. Individuals can also run a free exposure scan of their email address against known breach data to determine whether their information has appeared in previously published datasets.
