Overview
- The group posted a statement on a dark‑web site and released sample files said to include customer and transaction data, according to security firms that reviewed the leak.
- Askul acknowledges the statement and says it is investigating the facts, with no confirmation yet on any ransom demand or the extent of personal data exposure.
- The company detected the ransomware on October 19, halted orders and shipments, and is working on recovery with about 100 engineers including staff from parent company LINE Yahoo and external specialists.
- Security firms S&J and Trend Micro have tracked RansomHouse since at least late 2021 and describe it as an organized operation that pressures victims via data‑leak sites.
- The outage affected Askul’s logistics subsidiary, and reports say online storefronts run for clients such as Muji were also temporarily suspended.
