Japanese e-commerce and logistics company Askul has revealed that a recent data breach stemming from a ransomware attack has resulted in over 700,000 records being compromised.
Askul, which specializes in B2B sales of office and professional supplies, detected the attack on October 19, after cybercriminals started encrypting files on its systems.
However, prior to the data encryption being initiated, the hackers stole sensitive information from the company’s systems in an effort to increase their chances of getting paid.
The RansomHouse ransomware group took credit for the attack on Askul in late October, leaking data allegedly stolen from its systems on November 10 and December 2. The fact that data has been made public indicates that the company has refused to pay a ransom.
The cybercriminals claimed to have stolen more than 1 TB of data from the company.
