Incident analysis

ESSPL was listed by Ransomhouse ransomware, a group with 159 victims recorded in this database. The listing appeared on the group's leak site on December 29, 2025.

ESSPL is based in India and operates in the Technology sector. India ranks #8 worldwide for ransomware disclosures, with 499 victims in this database.

Sector context. Technology companies hold intellectual property, customer data, and source code — all highly valuable assets. A successful ransomware attack can also put downstream customers at risk through supply chain exposure.

Ransomhouse typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
