The incident happened last week and impacted business operations such as the company’s taxi dispatch system, currently offline.
Nihon Kotsu has an annual revenue of around $1 billion.
The company has 18,228 employees and has 8,588 taxis and over 2000 chauffeur vehicles.
Nihon Kotsu said in a statement, “We have confirmed that our internal systems were subjected to unauthorized external access (malware infection)”. It further added that “immediately after detecting the unauthorized access, we implemented emergency measures, such as disconnecting systems to prevent further damage.”
The company has closed down systems to offline to stop the threat but it has widely caused disruption in services.
The incident has disrupted web booking, car hire, reservation management, few internal systems, and telephone dispatch service.
Nihon Kotsu advised people to use the ‘GO’ taxi app instead, or use a taxi stand for booking a Nihon Kotsu vehicle. It is a major operational damage for a company that has one of Tokyo’s biggest fleets but the manual working is still operational. The hire car reservation system is offline.
In a different announcement, Nihon Kotsu said that the “labor taxi” service for pregnant women is shut down in a few areas.
The firm has brought in external cybersecurity experts to assist in investigating if there has been a data leak. The internal network has been separated to limit further spread.
Currently, no data leak has been confirmed and Nihon Kotsu will provide updates via official channels. “We are currently conducting a detailed investigation with specialized agencies into whether and to what extent data has been leaked. At this time, no information leak has been confirmed. However, in the unlikely event that we discover any leak or potential leak of personal information of our customers or related parties, we will promptly make an official announcement and contact those affected individually, in accordance with the law,” Nihon Kotsu said.
Customers of Nihon Kotsu are cautioned not to click on any links in suspicious communications purporting to be from the company and not to open anything they receive.
Mount Royal University (MRU) has confirmed that threat actors stole data and deleted files after breaching the university's network in a cyberattack that continues to affect recovery efforts weeks after the incident.
In an update published on its website, the Calgary-based public university said the attack occurred on June 17 and that internal technical teams are working alongside external cybersecurity specialists to investigate the intrusion, determine its full scope, and restore affected systems.
The cyberattack disrupted a wide range of university services, including internet connectivity, online platforms, and several internal systems used across campus. Recovery efforts remain ongoing, with the university warning that restoring all affected services may take several weeks or, in some cases, months.
According to the university's investigation, attackers gained unauthorized access to data stored on the institution's "H drive," a file storage system used by students and employees. Investigators have confirmed that files stored within certain folders were accessed and exfiltrated before the attackers deleted the original copies, a move that has further complicated recovery operations.
"We regret to inform our community that our investigation has now shown that data within certain folders on the University's 'H drive' was accessed and taken by an unauthorized actor," the university said in its advisory.
MRU said the affected folders contained information relating to current and former students, current and former employees, as well as other individuals whose data was stored within the impacted environment. The university has not yet disclosed the exact categories of information exposed or the total number of people affected.
The investigation also found that attackers deleted data stored on a separate departmental file storage system known as the "J drive." While the university said there is currently no evidence that information from the J drive was accessed or copied before it was erased, officials cautioned that recovering the deleted data remains an ongoing process and acknowledged that a complete restoration may not be possible.
The university has reported the incident to the Alberta Information and Privacy Commissioner and notified law enforcement authorities. Officials added that determining the precise impact for each affected individual will take time because the deletion of files has made forensic analysis more complex. Individuals whose information is confirmed to have been affected will receive direct notifications as the investigation progresses.
Responsibility for the attack has been claimed by the cybercrime group CMD Organization, which has published samples of what it alleges is stolen university data, including passport scans and other sensitive documents.
The group is demanding a ransom of 30 Bitcoin, valued at approximately $1.9 million at current exchange rates, and has reportedly given the university six days to respond before releasing additional data. CMD Organization also appears to operate an auction-based extortion model, advertising exclusive access to stolen datasets for the highest bidder through both clear web and dark web leak sites. At the time of writing, the group lists approximately 30 organizations on its extortion portal.
Founded more than a century ago, Mount Royal University currently serves about 11,560 students, including roughly 12,500 undergraduate learners.
As recovery work continues, the university said it will provide additional updates as more information becomes available. MRU is also offering two years of credit monitoring and identity theft protection to current employees and individuals who have worked at the university within the past five years.
After an investigation of the breach, the organization discovered that between March and April, the hacker accessed files carrying personal data of employees.
It is a Japanese industrial manufacturer famous for its construction and agricultural work. Kubota has plants in 120 counties and currently employs over 52,000 people. Kubota has an annual revenue of $20 billion.
The North American division consists of facilities that make utility vehicles, tractors, and mowers.
“We discovered that files maintained by our human resources team were accessed as part of this incident. We carefully reviewed these files, and on June 16, 2026, we determined that one or more files may have contained personal information related to certain employees and their dependents,” Kubota reported on its site.
As per the announcement posted on the Kubota USA portal, the following employee information may have been revealed:
The specific data that was exposed varies per person. Kubota also started sending personalised mails to inform the individuals about the exact impact on them.
The notification information consists step by step instructions for using Kroll identity protection to help the targets address the threats coming from the leak of their personal data.
Kubota has specially advised people to look out for bank accounts and healthcare related statements and promptly report any malicious activity to the concerned authorities.
Kubot has implemented robust security measures to avoid such incidents from happening in the future.
No cybercrime gangs, data extortion gangs, or ransomware gangs have claimed responsibility for the Kubota breach.
Kubota did not report any operational or business disruptions due to the breach.
On ensuring employee safety, Kubota said, “We take the privacy and confidentiality of our employees’ information very seriously. To help prevent something like this from happening again, we have taken and will continue to take steps to further enhance our existing security measures.”
The incident is improper privilege management that could have allowed threat actors to reveal sensitive data as unprivileged local users and launch arbitrary commands on default installs such as Ubuntu, Debian, and Fedora. Its alias is aka ssh-keysign-pwn.
