About the Metaencryptor group

MetaEncryptor is a ransomware group first observed in mid-2023, targeting medium-to-large enterprises in legal, technology, logistics, manufacturing, and finance sectors primarily in the UK, Europe, and Southeast Asia, using AES-256/RSA-2048 encryption and double extortion. Metaencryptor has listed 64 victims since August 2023.

Incident analysis

JH Technology was listed by Metaencryptor ransomware, a group with 64 victims recorded in this database. The listing appeared on the group's leak site on November 9, 2026.

JH Technology is based in South Korea and operates in the Technology sector. South Korea ranks #21 worldwide for ransomware disclosures, with 161 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.

Metaencryptor 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .
