From Phishing to LLMjacking: Threat Actors Targeting Cloud Billing Accounts for LLM Usage

Wiz CIRT investigation of LLMjacking campaigns against Google Cloud billing accounts. Attackers phished admins through malicious Google Search ads and a fake login page that captured MFA codes, then deleted the iam.allowedPolicyMemberDomains policy, added Gmail accounts as billing admins, and linked attacker-controlled projects to the victim's billing account. Victims saw tens to hundreds of thousands of dollars in Gemini API charges within 24 to 48 hours, with no log visibility into prompts. Includes hunting guidance for Workspace, Admin Activity and billing logs.

GhostAction Phishing Campaign

OpenSourceMalware analyzes a targeted phishing email from my-github[.]com (same server 193.32.204[.]199 as GhostAction's CI/CD exfiltration) that impersonated a GitHub new-sign-in alert. Recovered HTML and a HAR show a GitHub reverse proxy that captures passwords and TOTP codes, rewrites GitHub subdomains, and injects JavaScript that silently completes an OAuth device flow with repo, workflow and read:org scopes, then exfiltrates the token to TCP/8443. It includes a per-session redirect controller, mutable redirect behavior seen in URLScan, a victim's audit-log outcome (MFA stopped escalation), IOCs, and response guidance.

GhostAction Attack Escalates By Targeting GitHub Users

OpenSourceMalware's analysis of the latest GhostAction wave, where compromised GitHub accounts get malicious Actions workflows (security-audit.yml) injected across every writable repository, including an Oct 8 sweep of 346 repos via kitao and henrywoo. The new payload greps the checkout and full git history for credential patterns (AWS, Anthropic, OpenAI, GitHub PATs) and POSTs them over HTTP to 193.32.204.199/?c=monami. It also covers infrastructure reuse (phishing-heavy legacy IP, scanner activity), new watchlist domains my-github.com and my-gitlab.com, GitHub code-search hunting queries, a detection-confidence table, IOCs and incident response steps.

UAT-11985: AI-assisted event lures delivering real-time Google AitM phishing

Cisco Talos details UAT-11985, a spear-phishing campaign against Taiwan-based research organizations (impersonating institutions like the Taiwan European Union Centre and NCCU Institute of International Relations) that used AI-assisted, templated lure emails and poster-based QR code phishing (quishing) to drive victims to a real-time adversary-in-the-middle phishing kit. The kit impersonates Google sign-in across zh-CN/zh-TW/en locales, uses a split HTTP-POST/WebSocket architecture to mirror Google's live authentication flow and dynamically push MFA challenge screens, enabling full session-token theft and MFA bypass. Talos attributes the kit's localization architecture and lexical choices to a Simplified Chinese-speaking developer and publishes ClamAV/Snort coverage plus IOCs on GitHub.

Phishing Campaign Abuses Microsoft Power BI to Deploy Rogue RMMs

Huntress details a phishing campaign that abuses legitimate Microsoft Power BI dashboards (app.powerbi.com) to host a fake "Download Reference" lure that bypasses mail filters trusting the Microsoft domain. Clicking the lure triggers browser/environment fingerprinting and Telegram-bot-based victim telemetry exfiltration via attacker domains (dailylifeproject.site, burnsworth.site, etc.), then silently downloads rogue ScreenConnect installers; a chained CMD/PowerShell script (SCAutoFix.ps1) deploys a second ScreenConnect instance, uninstalls the first for evasion, drops the defense-evasion tool HideUL_x64.exe, and sets a recurring scheduled task before Huntress's SOC intervened.

China-nexus UAT-11587 targets government and policy organizations across Asia with Antino backdoor

Cisco Talos details UAT-11587, a China-nexus threat cluster targeting government, defense, and policy organizations across Taiwan, India, the Philippines, Cambodia, and other Asian countries with spear-phishing and a five-stage infection chain (HTA/WSF stagers, JScript decryptors, .NET BinaryFormatter/ActivitySurrogateSelector deserialization gadgets, and DLL sideloading via the signed GatherOsState.exe) to deploy a new Rust-compiled backdoor called Antino. Antino uses Microsoft Graph/Outlook/OneDrive as a dead-drop C2 channel instead of a traditional C2 server, supports shell/PowerShell execution, file transfer, shellcode loading with a sleep-mask evasion technique, and abuses the Windows Scripted Diagnostics framework for persistence; Talos also notes possible infrastructure overlap with Symantec's "Jewelbug" cluster and Arctic Wolf's UNC6384 reporting.

Phishing Abuses RMM Tools for Persistent Access

Microsoft Defender Experts document a July 2026 phishing campaign that delivers a masqueraded but legitimately signed MSP360 RMM installer (v2.5.0.67) via meeting-invite, Zoom, Adobe, and DHL-themed lures hosted on both attacker infrastructure and legitimate cloud services (S3, Cloudflare R2, Dropbox, GitLab, Supabase). After UAC-elevated installation and service persistence, the RMM.Agent.exe service launches PowerShell to silently install a ConnectWise ScreenConnect client via msiexec, which the actor then uses via RunFile to drop credential-theft and reconnaissance tools disguised as Windows/Defender/Phone Link components. A separate July intrusion used FaronicsDeployAgent.exe the same way to deploy ScreenConnect, showing the technique is not MSP360-specific; Microsoft provides IOCs, hunting queries, and mitigation guidance (Application Control, AppLocker publisher rules, ASR rules) but does not attribute the activity.

Microsoft's DART team details an investigation into Storm-3068, a threat actor that escalated from a self-service password reset account takeover into full control of an organization's Azure DevOps environment, then weaponized a malicious pipeline to harvest kubeconfig files and gain access to Kubernetes clusters. The actor also deployed the Atera remote management agent and the Chisel tunneling tool to establish reverse tunnels and alternate remote access, and exfiltrated seven stolen kubeconfig files into a repository. The report lays out the attack chain, DART's response, and hardening recommendations around SSPR monitoring, phishing-resistant MFA, branch protection, and pipeline permission controls.

DarkMe RAT: A VB6 APT Trojan Turned Conventional Infostealer

Huntress details a 2026 DarkMe RAT campaign that ditches the zero-days (CVE-2023-38831, CVE-2024-21412) previously used by the Water Hydra/EvilNum-linked group in favor of a plain phishing email delivering a disguised .pif file. The writeup reverse-engineers the full chain — msiexec pulling a wrapped MSI, a WSF stager, three obfuscated VB6 loader DLLs (Coconout.dll, Use.dll, Finalized.dll), a novel 329-app "inverted sandbox" gate, process hollowing into a signed clspack.exe, and Locked:// protocol-handler persistence — and corrects prior public reporting by showing the payload's "single-byte XOR" is actually a broken RC4 implementation. It closes with fresh C2 infrastructure (thatawful[.]boutique, port 7712), OSINT on delivery domains (including a related ClickFix/Efimer campaign), and concrete Sigma-style hunting rules and remediation steps.

Passkey-themed social engineering leads to identity and cloud compromise

Microsoft Security Research details an active campaign (since May 2026) where attackers use voice-phishing and SMS lures impersonating IT helpdesk passkey/SSO enrollment requests to drive victims into AiTM or device-code phishing flows, compromising Microsoft 365 identities. Post-compromise, actors register attacker-controlled MFA methods (e.g., software OTP tokens) for persistence, conduct systematic Microsoft Graph reconnaissance across users, groups, roles, and SharePoint/OneDrive/Exchange, then exfiltrate data at a measured pace using automated Node.js/python-httpx tooling while evading detection through IP rotation and anonymous proxies. The post includes real audit-log JSON examples, multiple KQL hunting queries for GraphAPIAuditEvents/CloudAppEvents, full MITRE ATT&CK mapping, and attributes the initial-access tradecraft to Storm-3121 and Storm-3032, which feed into ShinyHunters/Falcon and Helix extortion operations.

Inside Knight Office, a New M365 AiTM Phishing Kit

Huntress researchers uncovered the operator console for "Knight Office," a Flask-based adversary-in-the-middle (AiTM) phishing kit used to steal Microsoft 365 session tokens via a DocuSign-themed, self-spoofed lure that routes victims through Monday.com redirects and a compromised Joomla site to a fake Microsoft device-code authentication page. After capturing tokens, the attacker registered a rogue device in Microsoft Entra ID and bound a Windows Hello for Business key credential to the compromised account to maintain persistent, MFA-bypassing access even after token revocation.

How to Spot and Stop Rogue Device Joins

Wiz details how attackers abuse Entra ID's Device Registration Service to register rogue devices — often via device code phishing — to satisfy Conditional Access policies requiring joined devices, commonly using the open-source ROADrecon framework and predictable names like DESKTOP-XXXXXXXX. As attackers shift to AI-generated, benign-looking device names (e.g., "Work PC") and plausible User-Agent strings, static IOC matching breaks down, so Wiz shifted to behavioral detections: naming-convention anomaly detection against tenant baselines and correlating device-code-phishing alerts with subsequent device registrations, including a shared KQL query for identifying anomalous naming baselines.
