Summary · why it matters

The hacker group Ransomhouse has claimed responsibility for a cyberattack on Nichirei Corporation, a major Japanese frozen food producer, which continues to disrupt its delivery systems. Nobuo Miwa, president of S&J Corp., said that Ransomhouse typically uses ransomware to steal corporate data and has posted a statement about the attack on the dark web, with the group believed to have ties to Russia. In its statement, Ransomhouse said it is waiting for Nichirei to respond and urged the company to make contact to prevent the release of confidential data. Nichirei disclosed today that it is aware of the hacker group's claims and will work with police and relevant authorities, but declined to provide further details, including whether it has received a ransom demand. Nichirei said some affected servers contain personal information, and the company is in the process of notifying those concerned. Kyodo News reported that the cyberattack occurred about a week ago, causing system failures at Nichirei that have impacted frozen food deliveries to numerous supermarkets and restaurants, including KFC Japan, while some school lunch programs have also been affected. KFC Japan said today that operations have returned to normal after earlier reducing operating hours to cope with the impact of Nichirei's system issues.

Commvault Enables FedRAMP High Cloud for Federal Agencies

Commvault Systems has enabled its managed service provider partners to deliver FedRAMP High Authorized Commvault Cloud for Government services to U.S. federal agencies and defense contractors, broadening the company's public sector reach. The move lands on a stock with a 7 day share price return of 10.29% and a 90 day share price gain of 11.67%, though its 1 year total shareholder return is down 23.35% while the 3 year total shareholder return is up 111.68%. The most followed valuation narrative puts fair value at $161.15 against a last close of $145.21, implying roughly 10% upside, and rests on analyst expectations of about 10.6% annual revenue growth, profit margins rising toward 9.8%, and an 8.85% discount rate. That story leans on recurring SaaS economics, including 63% SaaS ARR growth, a 45% increase in multi-product customers, and 125% SaaS net dollar retention. A contrasting read notes the stock trades at a P/E of 88.1x versus 30.5x for the wider US Software group and a fair ratio of 38.7x, signaling valuation risk if sentiment cools.

The company cited new research from the fifth annual Cohesity Global Cyber Resilience Report showing that 56% of organizations said they were not well prepared to detect or contain unintended actions by AI agents and automated workflows, while 58% were not very confident in their ability to verify the integrity of AI models and related data following a cyberattack. Cohesity also said customers with Cohesity Data Cloud Enterprise Edition and Cohesity DSPM can now automate the protection of newly discovered sensitive data that is not already protected.
