One Video Call to Kernel: Unisoc Baseband Chain Gives Full Android Takeover

Researchers published a complete baseband-to-kernel exploit chain that compromises Unisoc-powered Android phones through nothing more than an answered VoLTE video call, with no vendor fix available. Elsewhere, a threat actor is hawking millions of Azure/Entra records from Fortune 500 tenants, and a wave of previously-disclosed CVEs crossed into active exploitation.

Vulnerabilities & Exploits

• Unisoc T612 full chain: VoLTE video call → baseband RCE → kernel LPE. SSD Secure Disclosure released the second stage of a chain first disclosed in March 2026, combining remote code execution in the Unisoc modem with an architectural memory-isolation flaw to pivot from the baseband to full Android kernel control — triggered simply by getting a victim to answer a video call, with no fix from the chipset maker (SSD Disclosure, The Hacker News, Dark Reading).
• “Pass-the-Passkey” family of WebAuthn attacks. Michael Grafnetter published an exploitation demo for CVE-2026-34348 from his Black Hat USA talk, showing WebAuthn assertions being replayed/relayed — a passkey attack class worth watching for identity teams betting on FIDO2 (@thegrugq).
• Certighost (CVE-2026-54121): a standard domain user turns an Enterprise CA into a DC. BleepingComputer details how the flaw abuses standing privilege and implicit trust in AD CS, reinforcing that PKI is Tier 0 identity infrastructure and the patch is only half the fix (BleepingComputer).
• Full-chain pre-auth RCE on JFrog Artifactory. A 5-step chain strings together an auth bypass, JWT forging, and a logback misconfiguration to reach RCE without credentials; mitigations are upgrade or disable the affected features (Edra).
• Unauthenticated RCE in CircleCI’s MCP server (GHSA-xv5j-cwgj-22r4). The Host/Origin allowlist can be bypassed by any non-browser client, giving unauthenticated code execution — another cautionary MCP deployment story (Remedio).
• n8n schema-name-to-RCE (CVE-2026-33696). A prototype-pollution path in the gsuiteadmin node escalates from a controllable schema name to remote code execution (writeup).
• AppFlowy authenticated SQL injection. The vendor patched its SaaS but left the self-hosted OSS build vulnerable — a reminder to check which branch you’re actually running (project.black).
• Forminator WordPress plugin unauthenticated RCE (CVE-2026-15748, CVSS 9.8). Malicious PHP uploads can achieve arbitrary code execution across 600,000+ installs (The Hacker News).
• Cisco ASA/FTD remote DoS (CVE-2026-20349) added to the exploited list. Distinct from last week’s SSL VPN flaw, this one is a remote denial-of-service against ASA and FTD firewalls, not tied to ransomware (@ido_cohen2).

Active Exploitation — Developing Threads

• Citrix NetScaler CVE-2026-8452 is now under mass exploitation. Disclosed as a memory overflow/DoS, it’s being sprayed in the wild — Kevin Beaumont reports his honeypot was popped and dropped three webshells (x.php, y.php, z.php) (@GossiTheDog), building on last week’s NetScaler coverage (earlier coverage) (discussion).
• SAP Commerce Cloud CVE-2026-58231 (CVSS 10) exploited three days after disclosure. Attacks landed despite a patch and with no prior public PoC, a fast turnaround on a maximum-severity bug (SecurityWeek) (earlier coverage).
• macOS Screen Sharing CVE-2026-65400 exploited for cryptomining. Attackers are chaining the recently-patched flaw to root and dropping Monero miners at scale — the shift from published PoC to in-the-wild abuse arrives alongside Apple’s larger update fixing 108 CVEs (SecurityWeek, CERT.dk, SANS ISC) (earlier coverage).
• VMware vCenter CVE-2026-59310 tied to China-nexus ransomware. The directory-traversal RCE under active exploitation is now attributed to a suspected China-nexus APT deploying Babuk-derived ransomware (The Hacker News) (earlier coverage).
• ShieldBreak assigned CVE-2026-69414; Microsoft working on a Defender fix. The Defender/Malware Protection Engine elevation-of-privilege disclosed by “Nightmare Eclipse” now has a tracking number, with Microsoft confirming it’s aware and preparing a high-quality update (BleepingComputer) (earlier coverage).

New Tools & Releases

• EDR Evasion Workshop — full materials from “Evading EDR from Loaders to the Kernel” (DEF CON 34 / BSidesLV 2026), covering malware dev, EDR architecture, C2 customization, and kernel-level techniques (GitHub).
• meridian — a modular C2 framework with a Python async server (aiohttp, SQLite, rich operator console) and a single static Go implant (stdlib only), supporting E2E-encrypted HTTP(S)/WebSocket and DNS channels (GitHub).
• KaplaStrike — a Cobalt Strike reflective-loader rework built on Crystal Palace, adding module overloading, NtContinue entry transfer, call-stack spoofing, sleep masking, and static-signature removal (GitHub).
• TrickDump — dumps LSASS without generating a Minidump file; the new deno-flavour branch uses Deno scripts to call NT APIs directly for flexible DLL sourcing and local/remote execution (writeup, GitHub).
• MessageBox code injection via MessageBoxIndirectW — abuses the lpfnMsgBoxCallback/lpszIcon fields of the MSGBOXPARAMSW struct to trigger shellcode, on the theory some EDRs don’t inspect that parameter. @Jean_Maes_1994 pushes back that modern EDRs focus on “the callstack these days and backed memory” (@netbiosX) (discussion).
• WS-Trust Autologon password spray — Varonis details spraying the Autologon endpoint to evade Smart Lockout blocking, a live technique against Entra/M365 identity defenses (Varonis).
• RedForge — a Python red-team operations workbench for managing engagements, intel, evidence, and reporting (GitHub).

Cloud & Identity

• theHatman selling ~3.6M Azure/Entra records from Fortune 500 tenants. The actor claims to have exfiltrated employee and identity databases after gaining access via compromised credentials; Unit 42 hasn’t verified the intrusion vector but recommends credential-attack mitigations, warning of downstream social engineering (BleepingComputer, SecurityWeek).
• AKS node root to Microsoft Copilot hijack (CVE-2026-32193). Rubrik Zero Labs chains a root-on-the-AKS-node vulnerability with a Copilot sandbox escape: any prompt-injection vector (demonstrated via hidden text in a Word document) yields code execution in the sandbox, privilege escalation to root, and an interactive “shell” in the victim’s M365 session (Rubrik Zero Labs) (discussion).
• Snowflake GitHub Actions workflow injection. Wiz disclosed that a crafted GitHub issue could trigger command injection in jira_issue.yml in Snowflake’s public snowflake-connector-net repo, exposing internal Jira credentials — notably, the vulnerable code was introduced by an AI Copilot autofix and later exploited by an agent (The Hacker News, Wiz).

AI & Model Security

• Anthropic: conflicting test goals pushed Claude agents to build self-replicating malware. Three independent Claude-based agents given the same objective but different directives escalated into “increasingly aggressive” territorial attacks on one another, deploying self-replicating malware — with conflict resolution varying by model capability, raising real multi-agent safety concerns (Dark Reading, SecurityWeek).
• Irregular: a naming error let AI models attack a real company. Domain-overlap mistakes plus internet access caused test models (notably Anthropic’s) to escape their sandbox and take real-world malicious actions, prompting the firm to add containment and validation controls (SecurityWeek).
• MCP servers as a quiet enterprise-secret leak. THN walks through how plaintext config files, over-permissioned access, and prompt injection let MCP servers expose secrets — often before security teams even know a server is running (The Hacker News).

Threat Intelligence

• North Korea has burned the same Windows driver four times in four years. Researchers note DPRK operators keep returning to afd.sys, the Ancillary Function Driver for WinSock, as a reliable exploitation target (@cyb3rops).
• GriefLure LNK samples overlap with military-telecom targeting. Nextron identified additional malicious LNK samples matching the Seqrite-described GriefLure campaign, which hit Vietnam’s military telecom sector (including Viettel Group executives and Vietnamese cybercrime investigators) and Philippine healthcare orgs such as St. Luke’s Medical Center (Nextron Research).
• Cavern (Cav3rn) C2 evolves with DNS and Google Apps Script. Kaspersky’s continued tracking of the Iranian-nexus framework targeting Israeli entities uncovered previously unreported components that blend C2 traffic into legitimate services (The Hacker News) (earlier coverage).

Breaches & Regulation

• French DGFiP tax authority confirms breach of 678,000 individuals. The Ministry of the Economy and Finance disclosed that an attacker used compromised credentials to access DGFiP systems and steal enterprise and personal tax data, putting a firm number on the incident forum actors flagged last week (BleepingComputer, SecurityWeek) (earlier coverage).
