Yellow Hat Reports Breach in Web Work Reservation System, Possible Leak of 1.8 Million Member Records
Yellow Hat, a major Japanese retailer of car parts and accessories, has confirmed a security breach affecting its online Web Work Reservation System.
The system, used by customers to book maintenance services such as oil changes, battery replacements, and vehicle inspections, was found compromised on August 18, 2026. Subsequent investigation revealed that personal information stored on the company's member server may have been accessed and leaked externally.
Up to 1,801,499 members could be impacted. The exposed data includes names, telephone numbers, email addresses, and member numbers.
Yellow Hat has reported the incident to police and the Personal Information Protection Commission. Affected members are being notified via email, SMS, telephone, or postal mail, with warnings to watch for any suspicious unsolicited contacts.

Detecting and Removing Secrets from Git History with Betterleaks and git-filter-repo
Developers often accidentally commit sensitive data such as API keys, passwords, database dumps, or private uploads to Git repositories. Even after removal in a later commit, these secrets remain accessible in the commit history and can be recovered by anyone with repository access. The recommended approach begins with scanning the entire history using specialized tools to identify leaked credentials across all branches and past commits. Once identified, the secrets must first be rotated or revoked before any history rewriting occurs. Tools like Betterleaks provide detection with keyword filtering, entropy analysis, and Base64 decoding, while git-filter-repo enables precise removal of files and replacement of secret strings throughout the repository timeline. The process requires careful backups, coordination with teams, and force-pushing rewritten history, followed by fresh clones for all contributors and CI/CD systems. Even after cleanup, organizations must assume that old secrets may persist in forks, backups, or caches and therefore treat rotation as mandatory.
Dropbox Lenovo ID Integration Flaw Exposes Thousands of Accounts Without Passwords
A flaw in the federated authentication process between Dropbox and Lenovo ID allowed attackers to compromise approximately 5,000 accounts between August 4 and August 21, 2026. Attackers registered a Lenovo ID using the email address tied to an existing Dropbox account due to missing email verification checks. They then logged in via the Lenovo ID option, and Dropbox automatically associated the identity with the existing account without requiring the original Dropbox password. Only accounts linked to the Lenovo ID integration and lacking two-factor authentication were affected. In fewer than one-third of the compromised accounts, attackers viewed or downloaded stored files. Dropbox responded by terminating all Lenovo ID sessions, removing existing associations, and updating the login flow to require the Dropbox password. Lenovo described the issue as stemming from a legacy integration and stated that its own customers were not directly impacted.
Kaspersky MDR Adds Automatic Correlation with Leaked Credentials via Digital Footprint Intelligence
Kaspersky has updated its Managed Detection and Response service to automatically match security events against data from compromised logins and passwords. The enhancement integrates Kaspersky Digital Footprint Intelligence to provide analysts with additional context when suspicious activity coincides with known credential leaks. According to the company, a quarter of attacks investigated in 2025 began with the use of stolen credentials. The update also introduces notifications for asset protection status, allowing administrators to address connectivity or telemetry issues that could affect monitoring quality. Managed service providers can now configure per-client license usage limits, and the service adds support for Kaspersky Embedded Systems Security for Linux 4.0. The MDR platform continues to deliver 24/7 infrastructure monitoring, threat hunting, incident investigation, and response capabilities.
Hacktivist Group Cyberleek Leaks Alleged GTA VI Gameplay and Map Details in Protest Against Digital-Only Releases
A hacktivist collective calling itself Cyberleek has released two purported gameplay clips from GTA VI along with images that may depict the full map of Leonida state. The group claims the leak is a protest against Rockstar's decision to sell physical editions that contain only a download code rather than an actual disc. Cyberleek is also demanding an end to digital pre-orders, the practice of selling built-in content as DLC, and mandatory online connectivity for single-player modes. Rockstar and parent company Take-Two have already filed DMCA takedown requests, which some observers view as indirect confirmation of the material's authenticity. The footage reportedly shows basketball mechanics, vehicle customization, trunk-opening animations, a stamina meter, and an honor system reminiscent of Red Dead Redemption 2. The alleged map includes five counties, an extensive rail network, and numerous small islands. At the same time, Cyberleek is promoting a Solana-based token and soliciting donations, prompting several outlets to question whether the operation is partly a cryptocurrency marketing scheme.
