SplitVPN Data Breach Exposes Personal Information of 865,000 Users

A data breach at the Russian VPN provider SplitVPN, formerly known as NotVPN, has exposed the personal details of approximately 865,000 users. The incident, which occurred in July 2026, involved a 17 GB SQL database containing emails, IP addresses, geolocation data, and partial payment card information. The stolen material was later distributed on a cybercrime forum, revealing 23.4 million user records, 13.6 million devices, and 2.6 million payment entries. Nearly 58 million connection logs spanning June 2025 to 21 July 2026 were also included, contradicting the company’s previous no-logs policy. The exposure is particularly concerning for users relying on the service to evade censorship and surveillance.

A significant data breach at the Russian VPN service SplitVPN, previously operating under the name NotVPN, has exposed the personal information of approximately 865,000 users.

The incident took place in July 2026 and involved the theft of a 17 GB SQL database that was subsequently shared on a cybercrime forum. The compromised dataset contained emails, IP addresses, geolocation details, and partial payment card information.

Analysis of the leaked material revealed 23.4 million user records, 13.6 million device entries, and 2.6 million payment transactions. The database also included nearly 58 million connection logs covering the period from June 2025 to 21 July 2026, documenting which device connected to which VPN server and the exact timestamps of those connections.

Although the logs do not record visited websites, the metadata can still link user accounts, devices, IP addresses, and specific servers. This level of detail directly contradicts SplitVPN’s earlier public claims that it maintained no connection or activity logs.

The exposure is especially sensitive for individuals who used the service to bypass government censorship and surveillance, as the retained metadata could potentially be used to identify and track such users.

Yandex Restores Access to 96% of Yandex Disk Data After Data Center Attacks

Yandex has recovered access to 96 percent of user data stored on Yandex Disk following attacks that damaged its data centers. Files including documents, photographs, and videos are once again available for opening, downloading, and sharing for the majority of users. The company continues to redistribute Disk capacity across independent external sites to improve overall resilience. Basic operations such as uploading, downloading, and synchronization are now functional, yet the web version still imposes restrictions on bulk actions like downloading entire folders or multiple files at once. Users are advised to rely on the desktop client or API for these tasks during the remaining recovery phase. Yandex publishes ongoing updates on the official Yandex 360 service status page and has not provided an exact date for full restoration.

k0t Operators Breach Corporate Firewalls and VPNs Exposing Over 70,000 Credentials

Group-IB and NyxLab detailed a campaign by the operator k0t targeting exposed firewalls and VPN portals. The operation collected more than 70,000 credentials from network devices and LDAP directory extractions across 84 compromised appliances. Initial access relied on CVE-2025-64446 directory traversal in FortiWeb, CVE-2026-0257 authentication bypass in Palo Alto GlobalProtect, and password brute-forcing against FortiGate devices. Attackers then leveraged CVE-2019-6693 to decrypt FortiOS configuration secrets and chained the noPac technique to reach domain administrator privileges. Persistence was achieved through MeshCentral, AdaptixC2, Atera, AnyDesk, and ngrok, while Rclone handled data exfiltration to cloud storage. Victims appeared on the Qilin and The Gentlemen leak sites, suggesting the operators likely act as initial-access brokers rather than direct ransomware affiliates.

OpenCode Reports Possible Exposure of Third-Party API Keys After Legacy System Breach

OpenCode disclosed that an attacker accessed a legacy system on October 16, potentially exposing API keys from external providers that users had stored in the Console. The incident affected only 1.4 percent of Console users, and the targeted system was already undergoing decommissioning. The company described the exposure as possible rather than confirmed and provided no details on the attack vector, duration, or number of keys involved. Some affected users reported unauthorized charges on their provider accounts. OpenCode stated that the incident was limited to keys stored in the Console and did not impact keys saved locally in its command-line or desktop applications. The firm notified impacted users by email on October 17 and is working with Anthropic, OpenAI, and Google. It recommended revoking and rotating exposed keys directly with each provider.
