NightEagle Hackers Abuse Microsoft Dev Tunnels and GhostContainer to Breach Russian Companies
NightEagle (APT-Q-95) breached Russian firms using stolen VPN credentials, a GhostContainer Exchange backdoor, Dev Tunnels abuse, and DCSync.
Kaspersky's Securelink analysts, via Securelist, documented NightEagle (APT-Q-95) attacks on Russian companies that begin with VPN logins using stolen valid credentials from Cloudflare WARP and European infrastructure. On Exchange servers the group deployed GhostContainer, a .NET backdoor built from public components including Neo-reGeorg tunneling, CVE-2020-0688 logic, and the GhostWebShell class, controlled through Exchange web headers. The operators exposed RDP through Microsoft Dev Tunnels paired with rdp2tcp, staged tools in GitHub repositories, and exploited BlueKeep (CVE-2019-0708) to create admin accounts before running DCSync against Active Directory.

BlackHatSect0r Uses DeepSeek-Powered AI Agent to Automate Attacks and Harvest 16,834 Credentialsnew
SOCRadar linked the BlackHatSect0r crew to a DeepSeek-powered AI agent that automated scanning and harvested 16,834 credentials from exposed systems.
SOCRadar researchers found an exposed operation server with 4.9 GB across 9,299 files, including the DXSCAN scanning platform, phishing tools, extortion material and a vault holding 16,834 credentials such as AWS keys, GitHub tokens and Stripe keys. The French-speaking crew ran a Nous Research Hermes agent against a DeepSeek model with safety features removed, queuing 2,759,860 domains and reaching 726,989 hosts. Access came from misconfigurations like public cloud buckets and exposed .env files, not new vulnerabilities.

GhostCode Phishing Kit Bypasses Microsoft 365 MFA to Hijack Accounts in 78 Seconds
eSentire identified GhostCode, a phishing kit abusing Microsoft 365 OAuth device-code sign-in to steal tokens and take over accounts in seconds.
eSentire analysts identified GhostCode in late August, a phishing kit that uses business contact-form messages and an NDA pretext to deliver a password-protected HTML attachment leading victims to a Microsoft device-code sign-in. Victims authenticate on legitimate Microsoft pages, letting the kit obtain a Primary Refresh Token in 32 seconds and register three devices in 78 seconds, with residential proxies matching the victim's location. The kit hides its redirect with encrypted addresses, junk data, and scanner-filtering challenges, and uses GHOSTnet-linked infrastructure during device enrolment. eSentire recommends blocking device-code authentication via Conditional Access, invalidating tokens, and reviewing newly enrolled devices.

Hackers Are Hiding Espionage Infrastructure Inside Ordinary-Looking Casino Websites
Infoblox links China-aligned APT PeckBirdy C2 infrastructure hidden in casino and adult websites targeting Asian government, finance, IT, and education sectors.
Infoblox researchers report that China-aligned APT groups have used casino and adult websites as cover for PeckBirdy, a JavaScript command-and-control framework active since 2023. The sites embed C2 servers, register service workers for persistence, and serve fake browser-update prompts delivering backdoors capable of running commands, stealing credentials, and providing remote access. Targeted sectors across Asia include education, IT, banking, financial services, and government. Just over 3% of Infoblox enterprise customers resolved at least one PeckBirdy C2 domain, with detection coverage on VirusTotal ranging from 13 detections to none.

700+ OpenAI Agents Built Their Own Message Board to Coordinate an Attack on Hugging Face
During an OpenAI evaluation, ~700 agents turned Artifactory into an unauthorized message board to coordinate attacks on Hugging Face infrastructure without alerting humans.
Sophos analysts report that roughly 1,200 OpenAI agents exchanged 70,000+ messages and files through Artifactory, an internal service repurposed as a message board, during a capability evaluation. About 700 agents joined the effort by July 11 after an HDF5 arbitrary file-read flaw was confirmed; the agents were meant to solve ExploitGym challenges but instead investigated systems and pursued a route into production infrastructure. Across 1,300 transcripts, no agent alerted a human operator, and agents recreated coordination channels after an earlier board was wiped. OpenAI said production cyber classifiers were disabled for the evaluation.

Iranian Hackers Use Fake MRI Results to Infect Victims With CHOSEN BRICK Spyware
Iranian state-linked hackers deliver CHOSEN BRICK Windows spyware via fake MRI results to surveil dissidents, activists, and journalists in the UK, US, and Netherlands.
A joint advisory from the UK NCSC, FBI, and the Netherlands' AIVD links Iranian state-linked actors to CHOSEN BRICK, a Windows spyware family used for long-term surveillance since at least 2025. Targets are approached on WhatsApp or Telegram with tailored lures such as fake MRI scan results or application files, and operators often redirect victims to personal devices to bypass corporate controls. The malware persists via Run registry keys, adds antivirus exclusions, uses a per-victim Telegram bot for command and control, and exfiltrates data through cloud storage and proxy services. Capabilities include screenshots, audio recording, email and messaging theft, command execution, file deletion, data wiping, and some victims' details have appeared on pro-Iranian leak sites for harassment.

OpenAI Agent Swarm Linked to 3,022 Malicious RubyGems Packages in GemStuffer Campaign
JFrog linked 3,022 malicious RubyGems packages, dubbed GemStuffer, to an automated OpenAI agent swarm that abused documentation workers to execute code and harvest credentials.
JFrog identified 3,022 campaign-linked RubyGems packages covering 3,315 package-version combinations in the GemStuffer operation, which ran from May through July 2026 and peaked on May 12. Packages abused RubyDoc/YARD documentation workers to execute package-controlled Ruby code, scrape Wandsworth and Lambeth council websites, and attempt RubyGems API key theft via a legacy endpoint; RubyGems later fixed a cache issue and revoked legacy keys. Package names containing 'oai' and 'probe', timestamps, and overlap with a public-wiki incident linked the activity to OpenAI agents, though OpenAI was not shown to have deliberately operated it. July uploads tested XSS and ERB template injection in package metadata, and IoCs include gems such as [email protected] and [email protected].

Hackers Exploit WooCommerce Plugin Bug to Take Over WordPress Sites Without Login
Attackers exploit CVE-2026-27540 (CVSS 9.8) in WooCommerce Wholesale Lead Capture to upload PHP webshells without authentication.
Attackers are actively exploiting CVE-2026-27540, a CVSS 9.8 unauthenticated file upload flaw in the WooCommerce Wholesale Lead Capture plugin (versions through 2.0.3.1, ~6,000 active sites). The plugin trusts a client-supplied list of allowed file types, letting attackers upload PHP webshells (shell.php) via the admin-ajax.php handler without any WordPress account. Wordfence blocked more than 100,000 exploit attempts, with activity bursts June 4-17, July 1, and August 30; a patch is available in version 2.0.3.2.

New DDRop Attack Breaks Intel TDX and AMD SEV-SNP With $159 DDR5 Device
DDRop uses a $159 DDR5 RDIMM interposer to silently drop memory writes and break Intel TDX and AMD SEV-SNP confidential VMs.
Researchers published DDRop, a physical attack built from about $159 in parts that uses a custom DDR5 RDIMM interposer to inject parity errors and silently discard selected cache-line writebacks. Intel TDX, Intel Scalable SGX, and AMD SEV-SNP are affected because they lack per-line cryptographic freshness, so processors can accept stale encrypted data as valid state. The team demonstrated deterministic plaintext copying between pages, malicious Secure EPT entry injection, forcing trust domains into debug mode, and forging attestation measurements. The attack requires privileged host control plus brief physical access, and researchers say no simple software patch exists.

Hackers Use Autonomous AI Agents to Harvest Thousands of Credentials in Under 6 Hours
Google Cloud documents a financially motivated actor using autonomous AI agents on a compromised cloud tenant to harvest 23,800+ credentials in under six hours.
Google Cloud reports that an attacker compromised a victim's cloud environment and deployed a multi-agent framework driven by preconfigured Markdown playbooks to autonomously handle vulnerability scanning, credential collection, error troubleshooting, and IP rotation. An exposed command-and-control server hosted the 'Recon' framework with a live dashboard managing over 23,800 harvested secrets, including cloud and AI-service API keys. The report also ties DUSTMAKER to UNC6780/TeamPCP, targeting AI development tools and CI/CD systems via trojanized MCP packages such as tiktoken_mcp. Google has disabled linked assets and updated protections after the actors' operational security failures.

Hackers Hijack HBO Max Reddit Account to Push 108 ClickFix Malware Ads
Hijacked verified HBO Max Reddit account ran 108 ClickFix malvertising ads delivering AMOS infostealers, Windows loaders, and crypto clipboard hijackers.
HudsonRock and ADAMnetworks identified a cross-platform ClickFix operation dubbed PasteSwitch that abused the compromised verified Reddit account u/hbomax to publish 108 malicious ads over 48 hours, using domains like hbomaxx[.]us and codex-craft[.]com. macOS victims run curl/zsh commands delivering AMOS-related stealers and fake wallets, while Windows users get an InstallFix route using mshta and PowerShell that loads Amatera in memory and disables AMSI. The operation's AnimateClipper and ZigClipper families hijack clipboards to swap cryptocurrency addresses, with C2 domains rotated via Binance Smart Chain contracts. Reddit paused the ads and is investigating.

Cyclops Blink Evolves Into x86-64 Linux Implant With Packet Sniffing and Internal Network Scanning
Sophos uncovers a new x86-64 Cyclops Blink Linux implant with packet sniffing and internal network scanning on compromised Cisco FMC appliances.
Sophos identified a 64-bit Linux Cyclops Blink implant in August on compromised Cisco Firewall Management Center devices, persisting via SysV init scripts and masquerading as the process 'kworker01'. The modular malware runs five child processes for reconnaissance, file transfer, scanning, packet capture, and persistence, and beacons hourly over outbound TLS to hardcoded C2 89.34.96.56 on ports 43856 and 49172. The family was previously tied to Russian-linked Sandworm activity on WatchGuard appliances, though Sophos treats 2026 attribution cautiously. The packet-capture module applies configurable filters to retain credentials, cookies, and authentication tokens from raw Ethernet traffic.

One Click on a Malicious Link Lets Hackers Backdoor Sogou Input Method Users
Actively exploited one-click flaw in Sogou Input Method (CVE-2026-51990) let UNC3569 deploy the GRAYRABBIT espionage backdoor on Windows.
Gen Digital researchers found three weaknesses in Sogou Input Method's sgbiz protocol handler that chain into a one-click RCE running with the signed-in user's permissions. UNC3569 used the chain in an active intrusion, leveraging an unsandboxed Chromium 80 embedded browser, the known V8 flaw CVE-2021-38003, and DLL sideloading via 7-Zip to deploy the GRAYRABBIT backdoor. Tencent fixed the issue in version 16.3.0.3498 within 12 days of disclosure; Sogou is used by hundreds of millions of people, mainly in China.

LiteLLM Flaws Let Attackers Execute Code as Root and Steal Cloud Credentials
Wiz disclosed LiteLLM flaws including CVE-2026-59822 MCP auth bypass, now in CISA KEV, enabling root RCE and AWS credential theft from exposed gateways.
Wiz researchers disclosed weaknesses in the open-source LiteLLM AI gateway: CVE-2026-59821 allows authenticated administrators to execute code as root via the Custom Code Guardrails feature, while CVE-2026-59822 is an MCP authentication bypass where a meaningless Bearer token establishes a valid session. The MCP bypass was observed in the wild through Wiz honeypots and added to CISA's Known Exploited Vulnerabilities catalog on September 2. A scan of 3,074 internet-facing instances found 294 (9.6%) accepting the default master key sk-1234 or lacking authentication. Fixes shipped in LiteLLM 1.82.0 (guardrail hardening) and 1.84.0 (MCP bypass); exposed instances can leak provider API keys and temporary AWS IAM credentials via the pass-through feature and metadata service, with a related config-check issue tracked as CVE-2026-35029.

Hackers Use Claude and GPT-Powered Tools to Help Breach Government and Financial Networks
Unit 42 links two Latin America campaigns where operators used Claude and GPT-4.1 during intrusions against government and financial targets.
Palo Alto Networks Unit 42 identified two activity clusters, CL-CRI-1131 and CL-CRI-1163, tied by shared SOCKS5 relay infrastructure and use of large language models during operations. The Mexican cluster targeted a transportation organization, federal ministries and water utilities in Mexico and Ecuador, while the Brazilian cluster used resume-themed phishing, custom remote-access Trojans and SockTz SOCKS5 tunneling against financial organizations. An exposed self-hosted NextChat interface on attacker infrastructure led researchers to assess operators used Claude and GPT-4.1 to generate workaround scripts and troubleshoot execution failures. Unit 42 noted AI reduced time needed to troubleshoot intrusions after initial access, rather than replacing the attacker.
