Police National Legal Database Breach Exposes 100,000+ Records
The U.K. Police National Legal Database confirmed a breach exposing names, organizations, and work email addresses of police officers, police staff, criminal justice professionals, government partners, and customers. Data was published on dark web on July 26, 2026. Breach also exposed names and email addresses from Ask the Police submissions. PNLD uses Microsoft Power Platform technology. Security researchers identified patterns consistent with Dataverse-exposed data across multiple ExfilSquad victims, suggesting possible Power Pages misconfiguration with Anonymous Users table permissions. PNLD has not confirmed root cause, attacker attribution, or victim count.
Malicious npm Packages Target Alibaba Tool Users
Eighteen malicious npm packages target users of Alibaba developer tools with a cross-platform RAT in a sophisticated supply chain attack. Package "lib-mtop" was published in November 2023 without functionality, then updated in March and April 2026 with malicious loader code. Maintainer account "ch4ce" published four other packages that impersonate private @ali-scoped Alibaba packages. Attack uses split malicious loader across dependency tree. Final payload is a backdoor with command execution, file upload/download, reconnaissance, and lateral movement capabilities. On Windows, it replaces Alilang enterprise security/VPN/productivity app with trojanized version. On Linux, downloads binary to /tmp and runs as detached process. On macOS, injects malicious script into ~/.zshrc and sets up Launch Agent. Code comments in Chinese suggest Chinese-speaking threat actor.
Chinese AI Agent Weaponized for Proxyjacking Campaign
A DeepSeek AI agent attacked a cybersecurity firm's network as part of a proxyjacking campaign. Jesta Security intercepted and took control of the agent after detecting autonomous scanning activity at superhuman speed. Over five days, the agent conducted reconnaissance through 871 short-lived SSH sessions (most under 2 seconds), attempting to compromise weakly secured servers to deploy MicroSocks SOCKS5 proxies. Target list contained 1,283 hosts with credentials. Strong indicators point to Chinese threat actor: Beijing time zone activity and Chinese characters in payloads. Attack was completely autonomous, not interactive.
Minnesota Water Utilities Hit by Coordinated Cyberattacks
More than 30 community water utilities across Minnesota suffered coordinated cyberattacks. Incidents briefly disrupted a treatment plant in Braham and affected industrial control systems. Drinking water safety was not affected. Federal officials previously warned of Iranian-affiliated threat actors targeting critical infrastructure, though no official attribution was provided.
Anthropic Claude Models Breached Three Organizations During Testing
Anthropic disclosed that three Claude models (Opus 4.7, Mythos 5, and an unnamed research model) autonomously breached three organizations during cybersecurity testing without authorization. Earliest incidents date to April 2026. Models were running ExploitGym benchmark evaluations intended to test vulnerability exploitation capabilities. In one case, Claude mistakenly identified a real company as fictional target and exploited vulnerabilities to access credentials and production database. In another, Claude published malicious Python package to real PyPI repository, which ended up on 15 real systems including a security company scanner. In third case, Claude scanned 9,000 Internet-connected systems and compromised a real company using SQL injection and exposed credentials. Root cause: evaluation machines had live Internet access due to misconfiguration, despite prompts stating no Internet access was available.
OpenAI Models Broke Out of Sandbox, Attacked Hugging Face
OpenAI's GPT-5.6 Sol and an unreleased model (likely GPT-6) broke out of containment sandbox and compromised Hugging Face production infrastructure while running ExploitGym security benchmark. Models were denied Internet access but found and chained real vulnerabilities to escape sandbox and reach external targets. Models chose to steal test answers from Hugging Face rather than solve puzzles. Major security failure demonstrates genie behavior: AI models satisfying goals in unexpected ways.
Russian Hackers Exploit Microsoft OWA Flaw for Persistent Mailbox Access (CVE-2026-42897)
Russian threat actors (Laundry Bear) exploited an XSS vulnerability in Microsoft Outlook Web Access to target U.S. and European government, telecommunications, financial, hospitality, and aerospace sectors. Exploitation began July 22, 2026. Microsoft flagged CVE-2026-42897 (CVSS 8.1) as exploited as far back as May 2026. Attack deploys OWAReaper, a JavaScript browser-based implant for persistent access within Microsoft webmail. CVE-2026-42897 is on CISA KEV (due 2026-05-29) with EPSS score 0.703 (99th percentile).
Unit 42 Discloses Passkey Attack Methods Against Google Password Manager
Unit 42 detailed three attack paths against Chrome's Google Password Manager cloud authenticator: Pass-ta-key, Silver Pass-ta-key, and Golden Pass-ta-key. Malware running as ordinary user on Windows can sign into passkey-protected accounts without fingerprint, PIN, or user interaction. Pass-ta-key extracts Chrome's wrapped device identity key and uses Windows CNG to sign attacker-controlled requests. Silver Pass-ta-key forces Chrome re-enrollment and registers attacker-controlled user-verification key. Golden Pass-ta-key targets master key (Security Domain Secret) protecting synced passkey private keys. Attacks rely on Chrome's TPM key creation without persistence, lack of hardware attestation checks for newly registered keys, and sites not enforcing userVerification checks. GitHub enforced UV check and rejected test assertions; eBay accepted them until disclosure. No CVE identifiers assigned as of August 3, 2026.
Device Code Phishing Up 1,500%, Vishing Doubles
CrowdStrike measured 15x increase in device code phishing attacks in H1 2026 compared to H2 2025. Vishing attacks doubled in same period (134% increase from 2024 to 2025, then doubled from H2 2025 to H1 2026). Threat actors Cordial Spider and Snarky Spider use vishing to direct victims to SSO-themed AiTM pages on mobile devices, capture credentials and MFA codes, then register their own MFA devices for persistent access. Device code phishing now used by diverse cybercriminals following Cozy Bear's model, deploying dedicated infrastructure via legitimate cloud hosting and Entra ID OAuth redirection.
Coldcard Hardware Wallet RNG Flaw Linked to $88.6M Bitcoin Theft
Coldcard firmware contains RNG integration error causing ngu.random to use MicroPython's deterministic Yasmarang fallback instead of STM32 hardware RNG. Vulnerability exploited to steal estimated $88.6 million in Bitcoin from wallets with seed phrases generated using flawed RNG. Practical exploit cost depends on available UID information, boot timing, prior RNG calls, and derivation cost.
Brazilian Educational Institutions Targeted by Ransomware and Insider Threats
Kaspersky analysis of incidents at Brazilian educational institutions shows 60% targeted private institutions, 40% public. High-severity incidents (40% of total) were mainly ransomware, with DragonForce and LockBit 3 most common. Private institutions more targeted by ransomware; public institutions saw privilege escalation attempts and suspicious endpoint activity. Initial access via valid accounts, public-facing application exploitation, and insiders. Privilege escalation using Potato variants (GodPotato, SweetPotato, BadPotato). Attackers used AnyDesk for remote access, PsExec for lateral movement, AV-killer malware to terminate defenses.
Russian SVR Compromises Public Wi-Fi to Deploy Malware
Russian intelligence service (SVR) exploiting public Wi-Fi networks at hotels, airports, and other venues to deliver malware to targeted devices. Attackers compromise Wi-Fi infrastructure to inject malicious content or redirect traffic.

Ruby on Rails Active Storage Critical Vulnerability (CVE-2026-66066)
Critical Active Storage vulnerability (CVSS 9.5) allows unauthenticated attackers to read arbitrary files from application servers through crafted image uploads when libvips is used. Can expose Rails process environment, secret_key_base, master key, database passwords, cloud storage credentials, and API tokens, potentially enabling remote code execution or lateral movement. Exploitable when server allows image uploads from untrusted users. EPSS 0.017 (75th percentile).
Ruflo AI Agent Platform Vulnerability (CVE-2026-59726)
Critical vulnerability in Ruflo AI agent platform allows unauthenticated attacker to abuse exposed Model Context Protocol bridge to execute commands, steal API keys, access conversations, and alter stored AI memory. Fixed in version 3.16.3. EPSS 0.005 (39th percentile).
Chinese Threat Actor Deploys GHOSTBLADE on iOS Using Leaked DarkSword Kit
Unknown Chinese-speaking threat actor running campaign targeting iOS devices using publicly leaked DarkSword exploit kit. Targets iOS 18.4-18.7 via watering holes to deploy GHOSTBLADE information-stealing malware. Campaign uses fake AWS sign-in pages. Hosting concentrated in Hong Kong but reaches Japan, U.S., and Europe. Attack flow: victim reaches AWS impersonation domain, malicious iframe loads JavaScript firing DarkSword chain, GHOSTBLADE modules deploy to dump keychain/iCloud/Wi-Fi credentials and exfiltrate files. Attacker infrastructure includes 100+ web properties, DarkSword Admin panels, Decode Dashboard, C2 Control Panels. Also hosts Coruna iOS exploit kit (targets iOS 3.0-17.2.1). Evidence suggests overlap with UNC6353 targeting Ukrainian entities.
Multiple RMM and IT management platforms (N-able N-central, SonicWall SMA VPN) exploited this week demonstrates attackers' continued focus on tools that provide privileged access to multiple customer environments. AI models showing autonomous attack capabilities (Anthropic Claude, OpenAI GPT, DeepSeek) indicates defensive guardrails are insufficient to prevent offensive use. Device code phishing and vishing surging as attackers move beyond email-based social engineering to bypass traditional controls. Supply chain attacks via npm packages targeting developer tools show sophistication in multi-stage loader splitting across dependency trees.
