The Qilin hacker group leaked approximately 1,440 files on the dark web containing business partner information and personal financial credentials.
-
More than 1.9 million people—employees, customers, even outside contacts got caught up in it.

Asahi says it didn’t pay any ransom and wants to get its logistics back on track by February 2026.
The group behind the attack on one of Japan’s biggest beverage companies has leaked a huge batch of data on the dark web. This includes employee info, customer service records, and so on.
The leak has thrown the company into another crisis and shows the security gaps run deeper than what they previously disclosed.
Asahi Data Breach Escalates with New Leaks
Notorious ransomware group Qilin has published a large chunk of data suspected to be part of the files stolen from Asahi Group online. This confirms that the hack reported in September indeed happened.
The hackers put around 1,440 files with business and personal info on the dark web. Based on the report, the personal data of nearly 2 million people is now exposed, and the company is trying to contain the damage.
Cybersecurity experts found financial institution IDs and passwords in the leaked data. This goes far beyond the personal information Asahi originally disclosed.
The breach began on September 29. The hackers got in through Asahi’s network equipment and slipped in ransomware, which encrypted data across many servers.
Asahi isolated its data center within hours. Their investigation later confirmed that employee PC data was exposed.
Last week, things got out of hand, and the Qilin group published the massive data trove online. Asahi has confirmed that the leaked information likely came from their systems. It’s the ransomware attack for which the hacker group demanded ransom from the firm in November this year.
The company is now verifying the exact contents. This leak includes business partner names and private financial credentials.
Who Was Affected and What Was Stolen
The scale of exposed information is staggering. The attackers compromised over 1.9 million records in total.
1.52 million customer service contacts had their names and addresses exposed. The breach affected another 114,000 external contacts for telegrams.
The attackers stole company data on 107,000 current and former employees. This includes birth dates, addresses, and phone numbers.
The attackers also took information on 168,000 employees’ family members, but fortunately, they did not access any credit card details.
Asahi’s Response and Recovery Timeline
Asahi maintains that they did not engage with Qilin and never conceded to pay any ransom. In a statement, Asahi’s group CEO Atsushi Katsuki said they were sorry for the trouble, assuring that work is in progress to restore the system quickly.
Their recovery plan indicates they will need several months to fully restore operations, with full logistics normalization targeted for February 2026. Product shipments are resuming in stages. The company established a dedicated contact line for affected individuals.
They’ve also submitted a final report to Japan’s Personal Information Protection Commission. This formal step acknowledges the breach’s severity.
Strengthening Defenses Against Future Attacks
Asahi is implementing stronger security measures. They are redesigning communication routes and tightening network controls. They will limit external internet connections to secure zones. This creates a more resilient system architecture.
They are revising their security monitoring systems to improve threat detection. They are also redesigning their backup strategies. These improvements aim to ensure rapid recovery if another attack occurs. Employee training and external audits will become more frequent.
The goal is to strengthen organizational security governance. Asahi wants to prevent a recurrence of this damaging breach.
A Stark Reminder of Digital Vulnerability
This breach shows that even industry giants are vulnerable. The Qilin group’s data dump proves stolen information has real consequences. Financial credentials and partner details are now circulating on the dark web. This ecosystem fuels espionage and national security threats as much as financial fraud, with stolen data from defense contractors and government programs becoming a high-value commodity for both criminals and hostile states.
If a breach exposes your data, closely monitor your accounts. Keep an eye out for emails appearing suspicious emails or login attempts. Changing your passwords now, especially for bank stuff, is smart.
Security should be the topmost priority for companies. Asahi’s planned security upgrades are necessary but reactive. You should always take proactive security measures rather than spend money on damage control after attackers breach your system. In today’s digital landscape, everyone must take a hands-on role in security and stay alert.
