Alu Perpignan, aluminium and PVC joinery, Occitanie
In October 2025, the hacker group Qilin paralysed the servers and computers of Alu Perpignan, an SME making aluminium and PVC windows and doors. Business applications and data became unavailable.
Qilin added the company to the list of victims on its darknet site, a hidden part of the internet. It claimed to hold internal and client data, and threatened to publish everything if the company does not negotiate.
According to the company, business was halted for about three weeks. The lost revenue is estimated at three months' turnover.
