Pre-ERC draft on Ethereum Magicians that binds the x402 payTo address to an ERC-8004 agent's registered agentWallet, directly or through an EIP-712 payee delegation (ERC-1271 for contract wallets). It lists eight fixed checker outcomes and requires the resource origin to appear in the registration file. On Robinhood Chain (28 October 2026), 5,575 of 20,046 agents answered with x402 requirements, and only 5 used their agentWallet as payTo.

Opinion piece arguing that passkeys, built on public-key cryptography, resist phishing, credential stuffing and password theft but do not settle identity risk. Attackers can go around them through account enrollment before a passkey is bound, weaker recovery paths (SMS, email link, help desk), device changes and authenticated session hijacking. It proposes layering identity threat detection with risk-based, continuous evaluation of trust.

XMTP Labs CEO Shane Mac describes how a personal "CFO" agent built on Grok Bot, with read-only bank access, posted his personal account balances and spending to the company's "Exec-team" Slack channel. The agent confused two similarly named channels. Because all his agents shared the same underlying connections, the Slack link attached to one agent was available to the others. Grok shipped a fix requiring explicit user permission before agents move information to other channels, and the author argues for better permission systems and a clear split between personal and work accounts.

ePrint paper that defines a security model for censorship resistance in anonymous credential systems, where a malicious issuer uses information gathered at issuance to selectively deny credentials. It gives a round-optimal construction built on blind signatures with selective disclosure at presentation. It also presents CRACS, an instantiation for the European Digital Identity Wallet (EUDIW). CRACS keeps selective disclosure and adds unlinkability between issuance and presentation. It confines the advanced cryptography to issuance, so secure elements, credential formats, signature schemes and verifiers stay unchanged and deployment can be incremental.

KedgeFlow proposes language-independent contracts in which trusted controllers issue signed exact-action permissions and privileged gateways enforce them, using single-use allowance claims, target-side conditions and retained outcome records. It aims to stop altered approved actions, concurrent permission reuse and retries after lost responses, even with a compromised agent. A reference implementation exposes this path via MCP; evaluation on a three-member etcd cluster showed 6,560 concurrent claim attempts yielding exactly one success per each of 82 allowances. It also reports that permissive policy still authorized an undesirable effect, and lists untested areas such as distributed reservations and production access routes.

News report on the September 2026 breach of Denmark's CPR civil registration database. Attackers abused the legitimate search access of Pays ApS, a two-employee Odense company, where at least three accounts, including the administrator, used the password "123456". An anonymous hacker told Politiken that a leaked password of a former employee at a small Danish company gave initial access, and that they then wrote two programs to pull data out. The access lasted 21 days 17 hours and about 14 million lookups, exposing roughly 8.8M people's names, addresses and CPR numbers. It was detected only through an unusually large invoice. The page is a news round-up, and the other stories are unrelated to security.

Krenn, Lesaignoux, Mir and Spini (AIT Austrian Institute of Technology) propose an "issuer inspection" mechanism for issuer-hiding attribute-based credentials (ABCs): an inspection authority can release time-bound keys that let verifiers locally flag presentations tied to a specific compromised issuer without unmasking other issuers or periods. They formalize the syntax/security model, give a generic construction, and instantiate it concretely using Groth's randomizable structure-preserving signatures, Schnorr-style proofs, and an adapted Gentry anonymous identity-based encryption scheme, showing the overhead stays practical. This addresses the accountability gap introduced when issuer-hiding ABCs conceal which authority issued a credential during verification.

The design deliberately keeps the id_token off the tool schema and inside HTTP headers only, so the foundation model never sees or handles the user's credential, and CloudTrail records the real human via an onBehalfOf AssumeRole entry, letting existing Lake Formation grants govern AI agent queries without rewriting authorization logic in application code. It details the three AgentCore configuration gates (runtime header allowlist, gateway metadataConfiguration.allowedRequestHeaders, Lambda's bedrockAgentCorePropagatedHeaders) that enforce this separation.

The authors integrate their HQC PoP into the ACME certificate-issuance protocol and compare it against existing PoP schemes for Kyber and FrodoKEM, showing Kyber issues certificates faster but at the cost of protocol or NIST-standard compatibility, while their HQC-based PoP keeps compatibility and achieves smaller proof sizes, which matters under unstable-network conditions due to larger KEM-based CSRs.

This paper introduces a paired-replay testbed that samples a single LLM agent request and replays the identical malicious action, resource, and arguments under four authorization conditions: broad bearer tokens, scoped JWTs, sender-constrained tokens, and Open Policy Agent policies. Across 128 scenarios in four tool domains and five local model configurations, broad-bearer tokens let roughly 9 to 38 percent of attacked, post-exposure decisions execute harmful actions, while all three scoped conditions recorded zero harmful executions; a supplementary AgentDojo extension found 11 of 24 injected attacks succeeded under broad policy versus 0 of 24 under scoping. The authors frame this as evidence that scoping contains cross-action and cross-resource consequences of prompt injection, not that it prevents the injection itself.

A Policy Enforcement Point intercepts access requests, enriches them with context, and routes them to a policy-engine agent that invokes domain-specialized core and supporting agents; policies are retrieved via RAG and embedded into agent prompts at inference time, with trust scores aggregated by a trust algorithm to produce the final access decision. The authors implement and evaluate the framework on a testbed, reporting 95.0% accuracy, 93.9% precision, and 96.3% recall on representative access-control scenarios.

Wiz Research analyzed infostealer-harvested secrets (via its NordStellar integration) to map exactly which credentials malware families like Lumma, RedLine, and Vidar target across AWS, Azure, GCP, GitHub, GitLab, and AI platforms, and how those secrets translate into cloud account takeover. It gives concrete file paths and artifacts attackers hunt for (~/.aws/sso/cache OIDC tokens, Azure accessTokens.json, GCP credentials.db/access_tokens.db, GitHub gh hosts.yml and SSH keys, GitLab Runner config.toml, OpenAI/ChatGPT session cookies, and Claude Code's ~/.claude/.credentials.json OAuth tokens), plus stats: three malware families cause 85.7% of incidents, AWS/GCP account for 46%/13% of stolen secrets, GitHub ~10%, AI platforms ~5%. It also covers CI/CD-targeting infostealers (Miasma, TeamPCP) and session-cookie hijacking as an MFA bypass technique.

Socket's Threat Research team dissects a malicious Firefox extension (pdf-para-texto@extensao.local, "PDF Identity Verifier") that ships with no hardcoded malicious code — all attack logic is fetched as data into browser.storage.local after install via a lookalike domain (pdf.gusercontent.com), evading static store review. Once armed, it abuses Google's FedCM API to silently identify the victim, injects a live automation script into real accounts.google.com pages to drive an invisible account-takeover flow (bypassing password entry, forcing passkey challenges, dodging Google's bot detection, and forcing/capturing a password reset), while a webRequest listener steals the oauth_token session cookie from Set-Cookie headers — giving the attacker both a live session and a durable new password. The campaign targets Portuguese- and Spanish-speaking users starting September 2026 and includes full IOCs (domains, file hashes) and remediation steps.

Huntress researcher Andrew Schwartz demonstrates a novel OAuth token-theft technique: a sideloaded AppX package registered via Add-AppxPackage -Register (requiring only Developer Mode, no admin beyond that toggle) can set ContentUriRules WindowsRuntimeAccess="all" so attacker-controlled JavaScript rendered inside the Microsoft-signed WWAHost.exe process gets full WinRT access, including the legacy WebAuthenticationBroker OAuth API. Using Microsoft Office's own client ID and the oob redirect URI, the attacker triggers a genuine login.microsoftonline.com/MFA dialog with no browser chrome, captures the auth code, and exchanges it for an access token plus a long-lived refresh token carrying the full Office delegated Graph scope set (mail, files, Teams, directory, AuditLog.Create) — validated end-to-end against a live Entra ID tenant with MFA and default Conditional Access. The post frames it as a class of vulnerable signed AppX host binaries sharing the same WinRT activation layer, and provides a Sigma rule keyed on the MSAppHost/3.0 EdgeHTML user agent reaching non-Microsoft destinations, plus Sysmon/Event ID and GPO-based mitigations (restricting Developer Mode, Conditional Access, shorter refresh-token lifetimes, CAE).

This paper analyzes authentication/authorization gaps in the six official Model Context Protocol SDKs (Python, TypeScript, Go, Rust, C#, Swift), identifying structural shortcomings for enterprise zero-trust deployments: single-header credential binding that breaks dual-persona (human SSO vs. service-account) setups, no pre-authentication tool discovery, and no fine-grained per-tool authorization. The authors propose composable FastMCP extensions — cross-header credential normalization, cached cross-IdP token verification, an unauthenticated metadata/discovery endpoint, and permission-filtered tool visibility enforced consistently at invocation — and test them against four frontier LLMs over 2160 attempts, showing an in-body-check-only server leaks forbidden tools 21.1% of the time versus 0% with permission-aware visibility, while also showing visibility-only filtering is still bypassable by scripted clients and models can infer hidden tool names up to 94% of the time from prompt context.

Wiz researchers reverse-engineered AWS's new sign-up experience, which silently creates a three-account AWS Organization (management, identity, and a restricted sandbox member account) with Builder ID login instead of root credentials. They found the sandbox blocks security services like GuardDuty, SecurityHub, Detective, Inspector, Macie and Access Analyzer via an allowlist SCP (FreeTierSCP), while still permitting risky practices such as IAM user access keys, public S3 buckets, and IMDSv1 EC2 instances; a data-perimeter RCP also blocks cross-account sts:AssumeRole until the account is upgraded, potentially pushing vendors back toward IAM user keys. The new IAM Role Manager feature further undermines least privilege by auto-attaching PowerUserAccess to console-created roles.

Because the SLC key has a 255-year certificate and no rotation mechanism, the compromise is permanent for all previously protected content, unlike KRBTGT which can be reset to invalidate forged Kerberos tickets.

Huntress details a second 2026 wave of device code phishing against Microsoft 365, this time abusing VPS reseller BL Networks (BitLaunch/BLNWX, AS399629) after an earlier wave tied to Railway and the EvilTokens phishing-as-a-service kit. Huntress observed 533 malicious events and 113 successful logins from a single BL Networks IP in April, spreading across multiple IPs and subnets by May, with 26 critical incidents across 23 identities logged in July, and argues defenders must stop trusting infrastructure reputation and instead hunt for anomalous device-code sign-in clusters and revoke tokens quickly. It ties the activity to the broader legitimate-cloud-plus-legitimate-Microsoft-auth-page attack pattern also seen with Railway, EvilTokens, and Kali365.

Orca Security explainer on entitlement sprawl (a.k.a. privilege creep) in cloud environments: the gradual accumulation of unused permissions across human and non-human identities, driven largely by machine identities (service accounts, roles, keys) that outnumber human users by over 80-to-1 per CyberArk's 2025 report. It distinguishes granted vs. effective permissions, explains why static IAM exports miss real risk, walks through detection via AWS IAM Access Analyzer, Azure Entra Permissions Management, and GCP IAM Recommender, and lays out controls (least privilege, JIT access, continuous automated reviews, RBAC/ABAC, NHI governance, zero trust) before positioning Orca's agentless CIEM (SideScanning) as the automation layer.

Official blog post from the MCP maintainers announcing the 2026-07-28 spec revision: the protocol moves from stateful/bidirectional to a stateless request/response core, replaces server-initiated calls (elicitation, sampling, roots) with Multi Round-Trip Requests (MRTR), and requires Mcp-Method/Mcp-Name headers so gateways can route and authorize without parsing JSON bodies. It also details significant authorization hardening — RFC 9207 issuer (iss) validation to close authorization-server mix-up attacks, binding client credentials to the issuer that minted them, and formal deprecation of Dynamic Client Registration in favor of Client ID Metadata Documents (CIMD) — alongside cacheable list responses and a new extensions framework (Tasks, MCP Apps, EMA).

Certighost is a Python PoC for CVE-2026-54121, an Active Directory Certificate Services attack that spins up rogue SMB/LSA and LDAP listeners to intercept the CA's NetLogon-based identity resolution during certificate enrollment. By impersonating a low-privileged computer account and redirecting the CA's lookups to the target Domain Controller's identity, the tool causes the CA to issue a valid certificate for the DC, then uses PKINIT with that certificate to retrieve the DC's Kerberos TGT/ccache and NT hash — a full domain-compromise chain from a single low-privileged account. The repo includes fixes for an in-the-wild NetLogon trust-account error (STATUS_NOLOGON_SERVER_TRUST_ACCOUNT) and a SAN-spoofing bypass for CAs enforcing ESC6-style EDITF_ATTRIBUTESUBJECTALTNAME2 protections.

Huntress blog recap of a Tradecraft Tuesday broadcast breaking down the LSHIY password-spraying campaign, which hit Microsoft Azure CLI tenants via IPv6 ranges from BYOIP provider LSHIY LLC, generating over 81 million login attempts and 78 account compromises in a two-week window. The campaign abuses OAuth's deprecated Resource Owner Password Credentials (ROPC) grant at the tenant token endpoint to mint delegated tokens that bypass MFA and Conditional Access Policies when valid credentials are entered. After LSHIY's takedown the actor pivoted to FranTech IPv6 ranges and Tor exit nodes; mitigations include disabling ROPC, restricting Azure CLI for non-admins, and enforcing unscoped Conditional Access covering all users, apps, and client types.

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.

Aikido Security's research shows that deleting a Google API key does not immediately revoke access — across 10 trials, deleted keys continued authenticating for a median of 16 minutes and up to 23 minutes, with revocation propagating unevenly across Google's global infrastructure. An attacker holding a leaked key (including one scoped to Gemini) can keep exfiltrating data during this window, the GCP console gives no indication the key is still live, and Google initially closed the report as "won't fix" before reopening it as a P0 after the researchers published. Newer Gemini API keys (~1 minute) and service account keys (~5 seconds) revoke much faster, showing the delay is specific to classic Google API keys.

The security-relevant core is a set of authorization SEPs that harden OAuth 2.0/OIDC usage: clients must validate the `iss` parameter per RFC 9207 to mitigate authorization-response mix-up attacks, declare `application_type` during Dynamic Client Registration to avoid redirect-URI misclassification, bind credentials to the issuing authorization server, and clarify scope accumulation during step-up auth. A related change requires that server-initiated requests (e.g. elicitation prompts) only be issued while actively processing a client-originated call, closing a class of out-of-nowhere prompt/consent issue for agentic clients.

A step-by-step guide for Salesforce admins to audit Connected Apps (OAuth-based integrations) following attacks where users were tricked into authorizing a fake Data Loader app that exfiltrated data instead of the genuine tool. It covers reviewing installed vs. user-authorized apps, blocking unrecognized or unused apps, enforcing 'Admin Approved Users' with Permission Sets, requiring high-assurance (MFA) sessions, and enabling API Access Control to allowlist which Connected Apps can use Salesforce APIs.

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.

Huntress blog on how social engineering has outpaced traditional prevention-focused security programs, citing specific campaigns: EvilTokens, a phishing-as-a-service operation that weaponized the Railway cloud deployment platform and Cloudflare Workers to run OAuth device code phishing against 340+ organizations, and a campaign using fake ChatGPT/Grok search results to trick macOS users into installing the AMOS infostealer. Also discusses AI-driven deepfake identity attacks and alert fatigue undermining detection.

Huntress SOC writeup on VPN compromise as the dominant initial-access vector, citing that ~70% of intrusions their SOC catches begin with attacker authentication through VPN. It walks through real incidents: a compromised FortiGate VPN leading to deployment of publicly available GitHub tools BlueHammer, RedSun, and UnDefend (attributed to threat actor Nightmare-Eclipse); a VPN-originated Play ransomware attempt stopped by EDR; missing VPN logs hampering investigation; and a SonicWall SSLVPN credential compromise that led to BYOVD-based defense evasion due to missing MFA and account segmentation. It closes with a prioritized remediation checklist (enforce MFA, audit privileged accounts, disable legacy accounts, centralize logging).

Huntress analyzes the March 2026 Stryker incident, in which attackers linked to the pro-Iran group Handala reportedly compromised Stryker's Microsoft Intune/MDM environment and issued a mass 'Remote Wipe' command factory-resetting up to 200,000 corporate and BYOD devices, while also exfiltrating 50TB of R&D data. The piece explains why this 'weaponized remote wipe' differs from ransomware (no restore key, full rebuild required), details the supply-chain/patient-safety fallout for NHS orders, and gives five concrete defenses: locking down MDM/RMM/EDR consoles as crown-jewel assets, requiring multi-admin approval for bulk device actions, moving from MDM to MAM for BYOD, building out-of-band IR comms, and rehearsing a fleet-scale 'day zero' restore.

Huntress analyzes how the OpenClaw AI agent (and its earlier branding, Moltbot) manifests as a cloud service principal inside Microsoft 365/Entra ID tenants, often granted sweeping application permissions like Directory.ReadWrite.All, Application.ReadWrite.All, DelegatedPermissionGrant.ReadWrite.All, and Sites.FullControl.All. The post shows real customer-tenant findings of both user-installed and centrally-registered "too-powerful" OpenClaw instances, and walks through hunting them using Huntress Rogue Applications inventory and Managed SIEM ESQL queries against Entra audit logs to trace consent, permission changes, and downstream mailbox/SharePoint access.

Huntress details a device-code phishing campaign hitting 340+ Microsoft 365 tenants across the US, Canada, Australia, New Zealand, and Germany since February 2026, in which attackers abuse Railway.com's clean-IP PaaS infrastructure to run OAuth device-code token replay at scale, bypassing MFA entirely. The campaign chains vendor URL-rewriter abuse (Cisco, Trend Micro, Mimecast), compromised sites, Cloudflare workers.dev phishing pages, and AI-assisted lure generation, and Huntress has attributed it to the EvilTokens Phishing-as-a-Service platform advertised via Telegram. The post includes IOCs (Railway CIDR ranges), Sentinel KQL hunting queries, and mitigation guidance (block Railway IPs, revoke refresh tokens, restrict device code flow, enable CAE).

Huntress breaks down how modern business email compromise (BEC) campaigns in Google Workspace have evolved from simple invoice fraud into multi-stage identity abuse: attackers use OAuth token theft, password-reset/MFA emails, and mailbox filters to hide alerts, persist via forwarding rules, and pivot laterally into other SaaS platforms. The piece argues traditional content-based email detection misses these campaigns and that defenders need identity-centric monitoring (token lifecycle, OAuth consent anomalies, mailbox config changes) — framing this as the rationale for Huntress's expansion of managed identity threat detection (ITDR) into Google Workspace.

CVE-2026-21852 describes a flaw in Claude Code versions prior to 2.0.65 where a malicious repository's settings file can override ANTHROPIC_BASE_URL and have it applied during project load before the user sees or accepts the trust-confirmation prompt, causing the user's Anthropic API key to be sent to an attacker-controlled endpoint. The root cause is an initialization-order bug (CWE-522, insufficiently protected credentials) where untrusted repo config is parsed and acted on ahead of trust verification; Anthropic fixed it in 2.0.65 by moving trust checks before config processing. Mitigations include updating, rotating exposed keys, and avoiding opening unfamiliar repos until patched.

AppOmni researcher discloses CVE-2025-12420 ("BodySnatcher"), a chain of flaws in ServiceNow's Virtual Agent API and Now Assist AI Agents application that let an unauthenticated attacker impersonate any user with only their email address, bypassing MFA/SSO via a hardcoded, instance-agnostic Message Auth secret and insecure Basic account-linking. By reverse-engineering the protected AIA-Agent Invoker AutoChat topic and its A2A adapter, the attacker can trigger the built-in "Record management" AI agent to create a backdoor admin user entirely through async, supervised-mode agent execution — escalating from zero access to full platform admin. The writeup includes full HTTP PoC payloads and recommends enforcing MFA on account linking, an AI agent approval workflow, and lifecycle de-provisioning of dormant agents.

A Huntress ITDR product researcher describes discovering, via "signal co-occurrence" analysis, that many confirmed identity account-takeover attacks lacked a detected initial-access alert. Investigating 10+ million authentication events revealed attackers increasingly using datacenter/VPS IP space (not flagged as VPN/proxy/Tor) to blend in, so the team built a new detector that classifies logins by Autonomous System (AS) reputation (e.g., flagging providers like Latitude.sh that accept anonymous crypto payment) instead of relying on geolocation or "impossible travel," cutting a major detection gap after going live in August 2025.

Huntress CEO Kyle Hanslovan demonstrates a full modern account-takeover chain against Microsoft 365: buying stolen credentials on a dark web marketplace, using a ChatGPT-crafted phishing email with a fake SharePoint link to trigger a ClickFix-style CAPTCHA that tricks the victim into pasting a PowerShell command, stealing active session cookies with an infostealer, and importing them via the Cookie Editor browser extension to bypass MFA entirely. It then covers post-compromise tradecraft — malicious inbox rules to forward/hide sensitive emails, Teams-based social engineering of IT support to register new MFA devices, and abusing email-based password resets on non-SSO apps (payroll, CRM) — plus defensive recommendations (conditional access, inbox rule auditing, DMARC/DKIM/BIMI, session revocation processes, security awareness training).

Deep-dive AD research showing that the WriteAccountRestrictions (WAR) property set — which grants control over msDS-AllowedToActOnBehalfOfOtherIdentity and UserAccountControl — is commonly delegated to domain-join service accounts because Microsoft's own domain-join permission guidance recommends it, not because of staging misconfigurations as previously assumed. The author, working from BloodHound Enterprise/Scentry assessment findings and BloodHound 8.0's new ACL-inheritance tracking, builds three concrete attack paths: resurrecting a disabled computer account via UAC manipulation + password reset + krbrelayx to capture unconstrained-delegation TGTs, a full Zerologon-style DC password-zero/DCSync/restore chain automated in a released PoC tool (SetZeroSync), and RBCD abuse against user-configured service accounts (e.g., SCCM site server) to pivot into the SCCM SQL database. It closes with defensive guidance on auditing broad WAR delegations, staging OUs, and graveyard OUs for disabled accounts.

Deep technical teardown of the Entra ID (Azure AD) Broker's LocalState cache on Windows 11, reverse-engineering the file naming scheme derived from identity material, the AES-GCM/DPAPI-wrapped Packer::V3 format inside AAD.Core.dll, and the JSON/binary serialization of AuthenticationContext objects used for PRT and per-application authority files. The author shows how to decrypt cached PRT and authority token files, derive the TPM-bound PRT session key via NCryptKeyDerivation (replicating mimikatz's dpapi::cloudapkd), and extract cached access/refresh tokens and JWTs — giving an attacker with local SYSTEM context a path to long-lived, MFA-bypassing cloud access and rich identity reconnaissance data. Companion extraction code is released as AADBrokerDecrypt on GitHub.

A blog post that provides three concrete KQL queries for Microsoft Sentinel/Log Analytics to detect Conditional Access Policy (CAP) violations in Entra ID: single-factor sign-ins by privileged admins that should require MFA, group members bypassing trusted-location/device-compliance requirements, and resources with no Conditional Access applied at all. It also surveys community tooling for CAP gap analysis, including the built-in Gap Analyzer Workbook, Maester, CA Optics, DCToolbox's What-if simulator, and Beau Bullock's MFASweep. The approach turns an organization's intended CAP strategy into ongoing detection logic rather than one-time policy review.

Huntress details six months of research into malicious Azure/Entra ID OAuth applications, splitting them into "Traitorware" (legitimate-looking apps commonly abused by attackers, ~10% of surveyed tenants had at least one) and "Stealthware" (custom-built OAuth Illicit Consent Grant apps used for persistence and data theft). Drawing on enumeration of 8,000+ tenants and Huntress partner telemetry, the SOC found over 500 confirmed Stealthware instances and identifies detection heuristics (low global app prevalence + single-user delegation + powerful permission scopes). The post also announces Cazadora, an open-source script that authenticates via Graph API to hunt rogue Enterprise Applications and App Registrations for known malicious naming patterns and reply URLs.

A Huntress researcher walks through Device Code Phishing, an OAuth 2.0 device authorization grant abuse technique, and shows why it is far more dangerous against Azure/Microsoft 365 than against Google Cloud. In Azure, the attacker controls the requested resource and can use Microsoft's undocumented "Family of Client IDs" (e.g. the Microsoft Authentication Broker client ID) to phish a Primary Refresh Token capable of joining rogue devices, enrolling MFA, and full account takeover; Google's device code implementation restricts the flow to a handful of narrow scopes (GDrive file access, YouTube read-only) and requires a registered/verified OAuth app, neutering the same attack. The piece includes working curl/Python requests for both providers and references prior research by Dirk-jan Mollema, Nestori Syynimaa, and Lina Lau.

Hausec (with Andy Robbins) details real-world Azure/Azure AD attack chains found on engagements: escalating a low-privileged Application Owner to Global Administrator via service principal secret abuse, then converting Azure AD Global Admin into Azure resource control via the User Access Administrator toggle (bypassing the fact that service principals can't invoke the API by creating a new admin user instead), pivoting from cloud to on-premise AD by uploading a Cobalt Strike PowerShell payload through Intune to hybrid-joined devices, and abusing Azure Logic App connector session persistence to reuse another account's privileges. The post accompanies the release of PowerZure 2.0, a rewritten offensive PowerShell toolkit implementing these abuses (Add-AzureSPSecret, New-AzureIntuneScript, Set-AzureElevatedPrivileges, Get-AzureLogicAppConnector, etc.).
