Autonomous AI Agents Compromise Thousands of Credentials in Under Six Hours

Google's GTIG reports threat actors using autonomous AI agents, credential stealers, and LLMs to steal AI models, API credentials, and harvest thousands of credentials.

Google Threat Intelligence Group says attackers are targeting proprietary AI models across healthcare, government, and media, exfiltrating API credentials, and co-opting victim cloud environments to run unauthorized AI workloads. TeamPCP (Altered Spider/UNC6780) is conducting supply chain compromises of PyPI, npm, and Docker Hub, deploying the SANDCLOCK and DUSTMAKER credential stealers, with DUSTMAKER using AI workspace poisoning and prompt injection for defense evasion. One financially motivated actor used an autonomous multi-agent framework to compromise thousands of third-party credentials in under six hours without human intervention. China-nexus groups UNC6508 and Basin Castle (Mustang Panda) used local open-weight LLMs and commercial LLMs like Gemini, Claude, and Codex for espionage tasks and evading provider monitoring.

New N0va Phishkit Targets North America and EU: A Growing Identity Risk for SOCs

ANY.RUN researchers uncovered the N0va phishkit targeting government, technology, consulting, and healthcare organizations across North America and the EU via device code phishing.

The N0va phishkit uses lures imitating Microsoft Teams, SharePoint, OneDrive, DocuSign, Google Drive, Dropbox, Zoom, and Adobe Sign to draw victims into a device code authentication flow. After the user completes legitimate authentication, N0va captures access and refresh tokens and abuses token-exchange and device-registration mechanisms to establish persistent SSO access to corporate resources. Because the flow relies on real Microsoft authentication, it can evade MFA-focused detections, and token access can outlive takedown of the phishing page. ANY.RUN says it observed the campaign in sandbox sessions, with targeting spanning government, technology, consulting, and healthcare sectors.

Infostealer Logs Expose Replayable AI Tokens That Can Bypass MFA

Okta finds infostealer logs contain thousands of replayable AI session tokens and API keys, letting criminals bypass MFA and access services from Google, Anthropic and OpenAI.

Okta analyzed a 7 GB infostealer dump from August 2, 2026 covering 5,871 infected machines in 162 countries and found 555 of 44,791 JWTs related to AI services, plus 1,843 unexpired JWTs and JWEs (largely set by OpenAI via NextAuth.js) and 24 still-valid API keys for Google Gemini, OpenAI, Groq and OpenRouter. Valid session tokens and API keys can be replayed with anti-detect browsers like Camoufox to bypass credential and MFA checks, fueling an underground market for AI account access known as LLMjacking, where attackers rack up victims' AI compute bills. Some 17.7% of the JWTs contained plaintext PII usable for social engineering. Google's GTIG reported growing buyer demand for Claude, Gemini, Cursor and Devin credentials, and Mandiant handled an incident where an actor used an exposed GitHub PAT to deploy unauthorized AI infrastructure and scale high-performance compute.

Legacy Lenovo login opens 5,000 Dropbox accounts to attackers

Dropbox warned about 5,000 users that attackers abused a legacy Lenovo ID login integration to access accounts and files between August 4 and 21.

Attackers exploited an integration allowing Dropbox access via Lenovo IDs, registering Lenovo IDs with Dropbox users' email addresses due to a flaw in Lenovo's email verification process. The compromise lasted from August 4 to 21; attackers accessed files belonging to fewer than a third of the roughly 5,000 affected users, none of whom had 2FA enabled. Bitcoin security company Casa co-founder Jameson Lopp reported attackers attempted to access one locally encrypted file. Dropbox expired all Lenovo ID sessions, severed the integration link, and urged affected users to reset passwords and enable 2FA while Lenovo's investigation continues.

Silver Fox Targets Japanese Manufacturer with 3

Chinese group Silver Fox used new vulnerable drivers and DLL side-loading to deploy ValleyRAT at a Japanese industrial manufacturer.

Cato Networks detailed a Silver Fox campaign against a Japanese industrial manufacturing organization combining new vulnerable-driver abuse (BootRepair.sys and EnPortv.sys alongside wsftprm.sys), DLL side-loading via Zeon Corporation PDF binaries, and NTDLL unhooking to deliver ValleyRAT (Winos 4.0), a Gh0st RAT variant. The chain starts with an invoice-themed phishing lure hosting attacker-controlled content on legitimate QQ and Tencent Cloud services. Shellcode is injected into svchost.exe via thread-context hijacking, and a dual watchdog design pairs payload monitoring with a scheduled-task batch script for persistence. A separate 180-day VirusTotal retrohunt found 146 Atlas RAT samples across six PDB builds, though the Silver Fox link remains circumstantial.

New VectraRAT malware-as-a-service at $250/month combines RAT capabilities, credential theft, clipboard hijacking, and a UACME-based UAC bypass; 38 victims observed.

VectraRAT is a previously undocumented MaaS platform with a Go-based VectraHub Linux C2 server embedding a Vue3 operator panel and a C++ Windows implant, rented from $250/month and linked to the aliases Vectra and Nyxel. It communicates over TCP port 3308 via a proprietary MessagePack protocol, steals browser and file-based credentials, and abuses UACME method 41 with debug-object handle hijacking via winver.exe and computerdefaults.exe. SOCRadar identified 38 live victim sessions in one week, 48% on corporate Windows editions, with delivery via the Amadey loader and ClickFix pages impersonating TurboTax.

FBI raises alarm over deceptive phishing campaign targeting prominent people

The FBI warns of an ongoing OAuth consent phishing campaign granting attackers persistent access to high-profile victims' cloud accounts without passwords.

The FBI says attackers impersonate government officials, journalists and event coordinators on commercial messaging apps to trick prominent individuals, their families and acquaintances into authorizing malicious OAuth applications on Microsoft or Google cloud services. Once approved, attackers gain persistent access to emails, files and other sensitive data; the access survives password changes and bypasses MFA, and can only be revoked by invalidating the OAuth token in security settings. The campaign has been tracked since late 2025, and the FBI advises independently verifying senders and granting access only to trusted applications.

UAT-10147 Uses AI to Scale Server Attacks, Deploys SPECTRE With EDR Bypass and Linux Rootkit

Cisco Talos exposes UAT-10147, a Chinese-speaking group using AI tools to automate intrusions, deploy SPECTRE, BadIIS, and rootkits against web servers worldwide.

Cisco Talos detailed UAT-10147, a Chinese-speaking cybercrime group conducting SEO fraud and data theft against Windows and Linux web servers in education, media, technology, and gaming sectors, with most victims in Brazil, Bolivia, China, Canada, and Vietnam. The actor exploits publicly disclosed vulnerabilities for initial access, including Zimbra (CVE-2022-27925) and Alibaba Nacos (CVE-2021-29441), and abuses Linux LPE flaws like CVE-2022-0847 and CVE-2021-3156 for root. Its toolset includes AI-assisted frameworks DeepAudit and PentestGPT, plus implants such as SPECTRE, BadIIS, Quasar RAT, Gh0stCringe, and Noodle RAT. An exposed directory contained a target list of roughly 170,000 URLs, with the US, India, UK, Germany, and Netherlands as top destinations.

Dark Caracal Deploys New Go Malware With Ethereum-Based C2 Fallback

Dark Caracal targeted a Venezuelan communications organization with new Go-based GoCaracal malware and an updated Bandook backdoor using Ethereum smart-contract C2 fallback.

Arctic Wolf Labs linked a June 2026 intrusion against a communications organization in Venezuela to Dark Caracal, an espionage group associated with Lebanon's General Directorate of General Security (GDGS). The group deployed a previously undocumented Go-based framework called GoCaracal in lightweight and extended builds alongside a Delphi-loaded Bandook backdoor, with delivery via phishing emails carrying weaponized SVG attachments through URL shorteners. The extended build uses a custom Solidity contract, BulletproofC2, on Ethereum to retrieve replacement C2 addresses without redeploying malware, and Arctic Wolf traced 249 related samples from January to July 2026 showing a modular evolution arc.

Hackers Deploy New SloppyRAT via ClickFix to Enable Ransomware Lateral Movement

Zscaler ThreatLabz reports SloppyRAT, a new Windows RAT delivered via ClickFix lures that supports reconnaissance, reverse SOCKS proxying, and lateral movement for ransomware affiliates.

Zscaler ThreatLabz first observed SloppyRAT in June 2026, delivered through multi-stage ClickFix chains that abuse finger.exe, a renamed curl.exe, and IronPython to load a reflective Python payload. The C++ implant implements 47 PowerShell-like commands via native APIs and direct syscalls, modifies Microsoft Defender settings, and establishes a reverse SOCKS proxy that lets operators pivot into internal networks. It is linked to CastleLoader and CastleRAT components and uses certificate-pinned HTTPS C2 with an EtherHiding fallback via Polygon JSON-RPC. Zscaler assesses it as an intrusion-enablement tool for ransomware operations, though flawed persistence logic suggests the family is still under development.
