A Russian hacker group in a statement released on the dark web has claimed responsibility for the cyberattack that caused a system glitch at Japanese office and household goods seller Askul, sources said Friday.
Askul said it is ¡°aware of this statement¡± and is ¡°currently working to verify the facts.¡±
The statement by the group, which calls itself ¡°RansomHouse,¡± was found by those including information security service provider S&J on Thursday night.
The group claimed that it stole some 1.1 terabytes of data from Askul, and customer information and purchase histories are now downloadable.
¡°The group disclosed only information that can seriously damage the company, so it seems that the cyberattack was well planned,¡± S&J President Nobuo Miwa said.
Askul¡¯s system failure occurred on Oct. 19, and the company temporarily halted shipments and order receipts. The system glitch affected companies that use Askul-affiliated logistics firms, including the Muji-brand household goods seller Ryohin Keikaku and sundry goods retailer Loft.
Askul has identified the cyberattack as a ransomware attack and reported it to police.
