This briefing period reveals a significant escalation in Russian state-sponsored cyber operations targeting secure communications platforms, alongside critical vulnerabilities in enterprise infrastructure and multiple high-impact supply-chain attacks. Russian intelligence services (likely APT28/APT29) have evolved their Signal phishing campaigns to specifically target backup recovery keys, enabling access to historical encrypted messages. The Jaguar Land Rover ransomware attack attributed to Russian actors caused an estimated $2.5 billion in economic damage to the UK economy, demonstrating the cascading impact of supply-chain disruptions.
Critical vulnerabilities dominate the threat landscape, with multiple CVSS 10.0 flaws disclosed in enterprise platforms including Budibase, Kestra, and OpenProject that enable unauthenticated remote code execution and complete authorization bypasses. The Polymarket supply-chain compromise resulted in $3.2 million in customer losses through malicious JavaScript injection. A total of 30 NVD entries were published, with 9 rated CRITICAL severity, primarily affecting authentication systems, workflow orchestration platforms, and industrial control devices. The telecommunications sector faces increased physical infrastructure risks as the FCC votes to strengthen undersea cable protection requirements.
Russian intelligence services demonstrate advanced targeting of encrypted communications and supply-chain infrastructure
FBI and CISA warn of evolved Russian intelligence phishing campaign specifically targeting Signal users' backup recovery keys. This technique enables attackers to decrypt and access victims' historical encrypted messages, representing a sophisticated evolution in secure communications compromise. Likely attributed to APT28 or APT29 based on TTPs.
Investigators attribute the Jaguar Land Rover ransomware attack to Russian hackers. The incident cost the UK economy £1.9 billion ($2.5 billion), rippling through 5,000+ businesses and halting car production. Represents one of the highest-impact ransomware attacks on record with measurable GDP impact.

Multiple CVSS 10.0 critical vulnerabilities disclosed affecting enterprise platforms, enabling complete system compromise
CVSS 10.0 CRITICAL: Unauthenticated visitors to any published Budibase app can read every document from backing databases (MongoDB, CouchDB, Elasticsearch, DynamoDB, REST). Where builders published PUBLIC write queries, attackers can create/update/delete arbitrary records without authentication.
CVSS 10.0 CRITICAL: Authentication filter treats any request path ending in /configs as public, forwarding without credential check. Suffix-match vulnerability allows attackers to bypass BasicAuth on all API endpoints by appending /configs to paths.
CVSS 10.0 CRITICAL: Similar path-based authentication bypass in Kestra OSS. AuthenticationFilter uses suffix match allowing attackers to access protected endpoints by manipulating request paths.
CVSS 9.9 CRITICAL: Official openproject/openproject Docker image ships with default ENV SECRET_KEY_BASE=OVERWRITE_ME as Rails master key. Combined with Marshal deserialization, any logged-in user can achieve RCE via deterministic cookie manipulation.
CVSS 9.6 CRITICAL: Cache store poisoning vulnerability in OpenProject enables authenticated attackers to achieve remote code execution through malicious cache manipulation.
CVSS 9.6 CRITICAL: POST /api/pwa/process-zip accepts builder-uploaded .zip, extracts with extract-zip, then validates icon paths from icons.json. Path traversal via ../ in icons.json allows arbitrary file writes as the web user during extraction.
CISA adds actively exploited Cisco Unified Communications Manager Server vulnerability to KEV catalog with Sunday patch deadline for federal agencies. Indicates in-the-wild exploitation by threat actors.
CVSS 9.8 CRITICAL: Daktronics Controller Firmware allows authenticated and unauthenticated remote users to escape intended directory boundaries and enumerate arbitrary file system paths.
CVSS 9.9 CRITICAL: SQL injection vulnerability in OpenProject baseline comparison timestamps functionality. Attackers can inject arbitrary SQL when requesting historic work-package attributes via timestamps parameter.
Multiple supply-chain compromises and active malware campaigns targeting enterprise users and cryptocurrency platforms
Polymarket suffers supply-chain attack after third-party vendor breach. Attackers injected malicious JavaScript into platform frontend, resulting in estimated $3 million in customer cryptocurrency losses. Polymarket commits to full reimbursement.
