ETDI: Comprehensive MCP Security Framework

ETDI (Enhanced Tool Definition Interface) is a proposed security extension to the Model Context Protocol that adds cryptographically signed and versioned tool definitions, OAuth 2.0 scope-based permissions, Cedar-policy-driven context-aware access control (via engines like Amazon Verified Permissions/OPA), and call-stack verification to stop tool chaining and privilege escalation. It is designed to counter two named MCP threat classes — Tool Poisoning (spoofed/impersonated tool definitions) and Rug Pull attacks (post-approval silent modification of tool behavior) — with concrete pseudocode for signature verification, version/integrity checking, and policy evaluation. The page functions as an implementation guide for MCP client/server builders wanting to harden tool approval and invocation flows.

Binary Security: Azure Logic Apps cross-tenant compromises (One Root Case)

Third post in a series on Azure Logic Apps API Connections, describing five critical cross-tenant privilege escalations that let an attacker use any other tenant's connection to reach its backend (Key Vault, Azure SQL, Jira, Salesforce). Techniques include path traversal via ARM DynamicInvoke and undocumented DynamicList endpoints, and abusing the host.api.runtimeUrl parameter in Consumption Logic Apps, including a validation-before-normalization bypass. The author reports $200,000 in bounties; Microsoft fixed all issues.

176 Vulnerabilities in Samsung Preinstalled Apps

Oversecured summarizes a multi-year research effort (2022-2025) that uncovered 176 vulnerabilities across Samsung's preinstalled system apps, all patched and rewarded with over 200000 dollars in bug bounties. The bugs cluster into categories including system UID-1000 privilege escalation, PendingIntent hijacking, intent redirection, implicit IPC/broadcast leakage of sensitive data, path traversal in system-privileged apps, and insecure WebView JavaScript-interface exposure via deep links; several were found in leftover debug/testing apps (FactoryCamera, Configuration Update) shipped with system privileges and no access controls. Some findings were also tracked under Samsung's own SVE identifiers (SVE-2023-1112, SVE-2023-0760, SVE-2023-0928).

ParaShells: Parallels Desktop Turns Appliance Install Into a Root Shell

JFrog researchers detail ParaShells, a local privilege escalation chain in Parallels Desktop 26.4.0 (build 57513) on Apple silicon that lets an unprivileged macOS user gain root. The chain combines a world-writable Unix socket for prl_disp_service, weak peer-credential-based authentication in PrlSrv_LoginLocal, and argument injection in the InstallAppliance extraction path where a crafted sVmParentPath breaks Qt's QProcess::splitCommand quoting to inject tar's --use-compress-program= flag, causing macOS tar to execute an attacker script as uid 0.

UAT-10147: Chinese-speaking adversary integrates agentic AI into post-compromise operations

Cisco Talos details UAT-10147, a Chinese-speaking cybercrime group exploiting one-day vulnerabilities in Windows/Linux web servers to deploy BadIIS, QuasarRAT, NoodleRAT, and SPECTRE implants, while also integrating agentic AI tools (PentestGPT, DeepAudit, and AI-orchestrated ysoserial workflows) to generate exploit playbooks, automate ASP.NET ViewState deserialization RCE, validate exploit success, and run reconnaissance/exfiltration end to end. Talos recovered AI-generated Python scripts and a findings log from the actor's C2 open directory showing semi-autonomous exploit refinement, OOB callback verification via webhook.site, and privilege escalation via SeImpersonatePrivilege/Potato exploits — evidence of a shift from AI-assisted scripting toward agentic offensive orchestration.

SleeperGem: Compromised git_credential_manager, Dendreo, and fastlane RubyGems Drop a Persistent Backdoor

StepSecurity analyzes SleeperGem, a coordinated RubyGems supply chain attack that trojanized git_credential_manager, Dendreo, and a fastlane plugin between July 18-19, 2026. The malicious releases act as CI-evading loaders that, on developer machines, download a second-stage native daemon and deploy.sh from an attacker-controlled Forgejo host (git.disroot.org), install dual persistence via systemd and cron, and attempt privilege escalation to plant a setuid backdoor mimicking ping6.

Solving GitHub's Secure Code game with an AI red teaming agent

Adversa AI documents how their autonomous AI red-teaming agent (a LangGraph planner/attacker/scorer/escalator loop) solved all five levels of GitHub's Secure Code Game Season 4 "ProdBot" challenge, capturing the flag at each capability tier without using any jailbreak vocabulary. Each level maps to a distinct agentic failure: a denylist-based sandbox bypassed via bash variable expansion hiding ".." from a static validator, an indirect injection surface via web browsing, an over-permissioned MCP Cloud Backup tool whose real file access exceeded its advertised sandbox-only scope, a skill-writable memory store that doubled as the security policy store (enabling privilege escalation via a never-expiring ttl=0 entry), and a multi-agent confused deputy where a Research Agent's unsanitized web content was passed to a privileged Release Agent as pre-verified context, triggering an unauthorized file read. The piece argues all five share one root cause: an agent acting on state it cannot independently verify, and that continuous automated red-teaming is needed to catch the class as new agent capabilities ship.

CitrixBleed 2 (CVE-2025-5777) 7Steps to Dragonforce Ransomware | Huntress

Huntress's Tactical Response team documents a repeatable intrusion cluster (tracked by Sophos as STAC3725) where an initial access broker exploits CVE-2025-5777 "CitrixBleed 2," a pre-auth memory overread in NetScaler ADC/Gateway login endpoints, to leak process heap and hijack valid Citrix session tokens even past MFA. The writeup walks through forensic proof of the session hijack, a portable local privilege escalation tool that plants a REG_LINK SymbolicLinkValue under the RdpBus device class to hijack the Group Policy state hierarchy and relaunch as SYSTEM via the AppMgmt service, followed by backdoor admin creation, ScreenConnect/Zoho Assist/Atera persistence, Impacket and Mimikatz for lateral movement/credential theft, and eventual DragonForce ransomware deployment. Includes concrete IOCs, log-based detection guidance, and hardening recommendations for NetScaler operators.

Authentication Bypass in the default configuration phpBB

Aikido Security's technical breakdown of CVE-2026-48611, a critical phpBB authentication bypass in the default configuration: by abusing the OAuth "login-link" feature's auth_provider query parameter, an unauthenticated attacker can force phpBB to use the trust-based `apache` auth provider (meant only for Apache Basic-auth proxies) and log in as any user, including admins, with a single request. The post details the vulnerable code in ucp_login_link.php/apache.php, shows a working PoC (curl/JS), explains a further UCP-to-ACP privilege escalation via the "founder" user's ability to self-promote to admin without a password, and describes an unauthenticated RCE chain via phpBB 4.0's Extensions Catalog fetching malicious extensions from attacker-controlled URLs. It also gives detection guidance (watch for `auth_provider=apache` + `mode=login_link`, including a GET/POST parameter-pollution bypass variant) and a disclosure timeline ending in the patched 3.3.17 release.

Trust No One: Automating macOS Privilege Escalation at Scale

XM Cyber researchers detail a macOS privilege escalation technique that lets a standard user disable EDR/MDM agents without admin credentials by exploiting stale kernel CDHash trust caches combined with NIB payload injection to impersonate trusted, code-signed application components. Once inside the trusted process context, the attacker uses an AppleScript-to-JXA-to-Objective-C runtime bridge (loading OSAKit.framework, forging Block_layout/objc_msgSend structures) to call unauthenticated privileged XPC methods like runProcessWithCommand: and ceaseSystemExtensionWithReply:, forcing security products to disable or remove themselves. The authors built an open-source scanner, XPC Hunter, to find this exposure across installed macOS apps at scale and recommend fixing it via xpc_connection_set_peer_code_signing_requirement() or SecCodeCheckValidity() peer validation.

LLMjacking evolved: Attackers are using stolen AI compute to build offensive agentic tools | Sysdig

Sysdig's Threat Research Team captured the full architecture of "VAPT," an autonomous multi-stage exploitation framework that a threat actor powered using a misconfigured, internet-exposed Ollama server (port 11434, no auth) instead of paid LLM APIs. The tool chains service fingerprinting, CVE matching, PoC/blind-SQLi generation, credential extraction, privilege escalation, and an autonomous orchestrator that confirms RCE via a VAPTb3gin/VAPTfin marker wrapped around `id` output, and was observed being actively developed against private HackTheBox-style practice ranges before any real-world targeting. It represents the convergence of LLMjacking (stolen inference compute) with fully agentic offensive tooling, and the piece includes captured system prompts, IOCs, and hardening guidance for self-hosted model servers.

Observing Privilege Escalation in Kubernetes (EKS CloudWatch Observability Add-on)

Reversec details a privilege escalation vulnerability in AWS EKS's CloudWatch Observability Add-on: the cloudwatch-agent service account, deployed via DaemonSet to every node, had cluster-wide permission to update ConfigMaps, allowing any attacker who compromised a node (e.g. via a privileged pod with hostPath access) to steal the agent's service account token, rewrite the aws-auth ConfigMap, and grant themselves cluster-admin via system:masters. The flaw existed in the default, unmodified add-on configuration (no misconfig required) and was found in two separate client engagements; AWS acknowledged it and shipped a fix in add-on v5.3.0-eksbuild.1 that scopes the update-ConfigMap permission to a namespaced role, though a related privilege-escalation path via the nodes/proxy permission (disclosed separately by Graham Helton) remains unaddressed until Kubernetes 1.36's fine-grained Kubelet authorization lands in EKS.

Threat Actors Weaponize Tiflux RMMs in Malspam Attacks

Huntress documents a malspam campaign, active since February 27, that uses fake "service agreement" document lures behind a CloudFlare CAPTCHA to trick targets into installing Tiflux, a lesser-known Brazil-based commercial RMM, before pivoting to UltraVNC, Splashtop, and ScreenConnect for persistent remote access. The Tiflux installer bundles suspicious extras beyond the legitimate agent: a decade-old UltraVNC build with hardcoded plaintext-recoverable passwords, an expired UltraVNC code-signing cert, registry files that stage a hidden TightVNC service (enabled even in Safe Mode) and a passwordless PuTTY SSH key to a peopleone[.]com[.]br server, registry tweaks that suppress Windows Secure Attention Sequence consent prompts, and a known vulnerable HwRwDrv.sys driver linked to privilege escalation with a revoked signing certificate. Huntress frames this as another entry in the ongoing "LOLRMM" pattern of attackers abusing legitimate commercial RMM tools for stealthy access and persistence.

dMSA Ouroboros: Self-Sustaining Credential Extraction in Windows Server 2025

Huntress and Akamai researchers detail "dMSA Ouroboros," a technique where a low-privileged domain user with CreateChild on any OU/container plus WriteProperty on a target account creates a delegated Managed Service Account (dMSA), plants a Shadow Credential via msDS-KeyCredentialLink for PKINIT auth, and writes the dMSA's own SID into msDS-GroupMSAMembership so it authorizes itself via S4U2Self to continuously extract the superseded account's NT hash. The resulting loop survives password rotation, survives deletion of the original attacker account, and can lock Domain Admins out of remediation, with deletion of the dMSA object being the only effective fix; the post also proposes BloodHound detection edges and Microsoft declined to service it as a CVE, classifying it as persistence rather than privilege escalation.

Detecting insiders on GNU/Linux servers

A practical guide to building an auditd-based Linux intrusion detection ruleset covering reconnaissance (tcpdump/wireshark/nmap install and execution), privilege escalation (setuid/setgid syscalls, sudoers and /etc/passwd modification, process injection via ptrace and process_vm_writev), container escape via host filesystem remounting, lateral movement (xfreerdp), persistence (SSH authorized_keys, cron, systemd units, udev rules), and detection evasion via /dev/shm. Each rule is accompanied by working C PoCs and ausearch log output to validate detection, plus discussion of auditd's limitations (no path globbing, kernel syscalls only, incomplete file-change detection). Based on the author's incident response and pentesting experience, the rules and full ruleset are published on a companion GitHub repo.

Privileges relinquishing order in C

Explains a subtle Linux privilege-dropping bug: calling setuid() before setgid() in a SUID/SGID-root binary leaves the saved set-group-ID privileged, letting a later setgid(0) call silently regain root group privileges due to POSIX semantics. The author provides compiled C PoC programs (drop_bad.c / drop_good.c) showing the wrong order failing to fully drop privileges versus the correct order (setgid then setuid) properly relinquishing them, and notes this becomes exploitable for privilege escalation when combined with a code-execution bug later in the program.
