Have it both ways: stay discoverable in search while disallowing AI training

Cloudflare launches Disallow AI Training setting letting sites block AI training via robots.txt while staying indexed in search; Apple, Google, and Microsoft honor it.

Cloudflare announced a 'Disallow AI Training' setting that publishes a no-training preference in robots.txt so sites can block AI training (including by mixed-use crawlers) without losing search indexing. Apple, Google, and Microsoft meet Cloudflare's new 'Accountable' designation, which requires training/summary opt-out mechanisms, URL-level training visibility, and assurance that opt-outs don't affect search rankings. Cloudflare cites that under 1% of its sites block search bots while 17% block AI training, and its Block settings now apply to mixed-use crawlers as well. Granular controls over how much content appears in AI summaries are planned for early next year.

When scanners miss the attack: how Cloudflare Client-Side Security protects storefronts

Cloudflare's Page Shield ML uncovered four malicious JavaScript campaigns on storefronts, including affiliate fraud and a remote-backdoor script, that VirusTotal and URLScan missed.

Cloudflare's Page Shield ML detected four client-side JavaScript operations (eight payloads) in live traffic on online storefronts, enabling affiliate commission hijacking, clickless affiliate theft via hidden iframes, user tracking with a remote-code backdoor, and cloaking of paid mobile visitors. Seven of the eight payloads were absent from VirusTotal and URLScan returned no malicious verdict for any, including a Lnkr-family payload indexed unclassified for roughly 2.5 years. Detection relies on a graph neural network over JavaScript syntax trees, an LLM second opinion on Workers AI, and a frontier-model ensemble voting across benign, magecart, other malware, and cryptomining labels.

BambooToken Malware Uses MQTT to Control Windows and Linux Systems

Lumen uncovers BambooToken, a stealthy multi-platform malware using MQTT C2 and Tendyron DLL sideloading to compromise Asian and South American organizations.

Lumen Black Lotus Labs disclosed BambooToken, a previously undocumented malware family active since at least February 2023 that controls Windows and (since December 2025) Linux hosts via the MQTT protocol for C2. The malware sideloads a rogue OnKeyToken_KEB.dll via Tendyron's OnKey PKI token software, gathers host details, and uses a WMI-based plugin to enumerate installed antivirus products and exfiltrate them to C2 domains proxied through Cloudflare. A dozen compromised entities were detected across Asia and South America, and DLL sideloading plus SoftEther VPN usage suggests a China nexus.

BambooToken: The Malware That Speaks MQTT to Stay Under the Radar

Lumen's Black Lotus Labs uncovered BambooToken, a Windows and Linux malware family using MQTT broker-based C2 and DLL sideloading across Asia since February 2023.

Lumen Black Lotus Labs identified BambooToken, a multiplatform malware family that exchanges commands through MQTT brokers so infected hosts never contact the C2 server directly, active from at least February 2023 through July 2026. The Windows variant sideloads via Tendyron's OnKey hardware-token software used in Chinese banking and government, or impersonates Kingsoft Office, without either vendor's signing certificate being compromised; a Linux build appeared by December 2025 with shell, file transfer, and system information commands. Victims include MikroTik and DrayTek routers in Singapore, Cambodia, and Vietnam reached after internet-wide SNMP scanning, and Lumen cannot attribute the family to any known actor.

Fake AI trading agent steals crypto wallet passwords

Fake AI crypto trading agent sites deliver Needle Stealer, which replaces browser wallet extensions to steal wallet passwords, HP reports.

HP researchers tracked campaigns between April and June 2026 in which a fake AI trading agent site, tradingclaw[.]pro, distributed a Microsoft-signed OLEView executable that DLL side-loads a malicious iviewers.dll and launches Needle Stealer via process hollowing. Needle replaces one of seven browser wallet extensions, including MetaMask, Coinbase Wallet, and Phantom, to capture wallet passwords. Related campaigns used QR-code invoice phishing leading to fake OneDrive pages, Phantom Stealer sold as a penetration testing tool with VBScript-to-PowerShell steganographic loaders, and image-hidden payloads delivering XWorm, PureLogs Stealer, and Formbook; a perceptual-hash VirusTotal search found about 400 distinct rigged images.

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.

NightEagle Hackers Target Russian Companies Using GhostContainer Backdoor

Kaspersky links NightEagle (APT-Q-95) intrusions in Russia to stolen VPN credentials, the GhostContainer Exchange backdoor, BlueKeep exploitation, and covert tunneling for espionage.

Kaspersky's Global Emergency Response Team attributes new intrusions against Russian companies to NightEagle (APT-Q-95), active since at least 2023 and previously focused on Asian organizations. The group uses valid VPN credentials, deploys the .NET-based GhostContainer backdoor on Microsoft Exchange servers, and tunnels RDP via Microsoft Dev Tunnels and rdp2tcp. In one incident operators exploited BlueKeep (CVE-2019-0708) to create an administrator account, and they performed DCSync replication against Active Directory to harvest domain password hashes. GhostContainer reuses code from Neo-reGeorg, ExchangeCmdPy.py (CVE-2020-0688), and ysoserial, and tampers with AMSI and Windows event logging to evade detection.

Kaspersky links NightEagle (APT-Q-95) intrusions in Russia to stolen VPN credentials, the GhostContainer Exchange backdoor, and Microsoft Dev Tunnels abuse.

Kaspersky's Global Emergency Response Team attributes new intrusions against Russian organizations to NightEagle (APT-Q-95), active since at least 2023 and previously focused on Asia. Initial access uses valid VPN credentials, followed by the .NET GhostContainer backdoor on Microsoft Exchange servers, which abuses ASP.NET view state injection, disables AMSI and event logging, and proxies traffic. Operators moved laterally via RDP, abused Microsoft Dev Tunnels with rdp2tcp, used Impacket atexec and netsh portproxy, and in one case exploited BlueKeep (CVE-2019-0708) to create admin accounts and attempt DCSync.

Three Threat Groups Target Russian Enterprises With Backdoors, Ransomware, and Wipers

Kaspersky details NightEagle, Hacking Cat, and Toy Ghouls targeting Russian enterprises with Exchange backdoors, Gorilla RAT, and destructive Monkey ransomware.

Kaspersky reports three threat clusters targeting Russian enterprises: NightEagle (APT-Q-95), the pro-Ukrainian hacktivist group Hacking Cat, and Toy Ghouls. NightEagle uses compromised VPN credentials and the GhostContainer modular backdoor to fully compromise Microsoft Exchange servers, chaining CVE-2020-0688 exploitation, BlueKeep (CVE-2019-0708), Active Directory vulnerabilities, and DCSync to seize domain controllers. Hacking Cat exploits Exchange flaws including CVE-2021-26855 and CVE-2026-42897 to deliver the Gorilla RAT and multiple Monkey ransomware variants written in Rust, .NET, C++, and Golang targeting Windows, Linux, and VMware ESXi, with some variants acting as wipers that never store the encryption key.

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.

GhostCode Abuses Microsoft Entra Device Enrollment to Maintain Access After Token Revocation

eSentire exposes GhostCode, a device-code phishing kit that abuses Microsoft Entra device enrollment to persist even after stolen tokens are revoked.

eSentire's Threat Response Unit observed GhostCode campaigns in late August 2026, using BEC-style social engineering that impersonated procurement staff, including BJ's Wholesale Club, via Salesforce contact forms. Victims received password-protected HTML lures disguised as a FlipBook document portal, with junk-data padding, HTML comment injection, and AES-256-GCM encrypted redirects gated by anti-bot checks. The kit exploits the OAuth 2.0 device authorization grant, prompting victims to approve real Microsoft device-code sign-ins with MFA. Within 78 seconds of approval, attackers registered three Entra devices and obtained a Primary Refresh Token, so rogue device registrations persist even after session token revocation.

NightEagle targets Russian companies

Kaspersky links NightEagle (APT-Q-95) attacks on Russian firms to compromised VPN credentials, a GhostContainer Exchange backdoor, RDP tunneling, BlueKeep exploitation, and DCSync.

Kaspersky's Global Emergency Response Team investigated NightEagle (APT-Q-95) incidents over the past year, finding the group—active since at least 2023 and formerly focused on Asia—now targeting Russian businesses. Attackers used compromised VPN credentials and deployed the GhostContainer .NET backdoor on Microsoft Exchange servers, built from Neo-reGeorg, a CVE-2020-0688 exploit, and ysoserial's GhostWebShell, injected in memory via VIEWSTATE manipulation with AMSI bypass. For lateral movement they combined Microsoft dev tunnels with rdp2tcp over RDP, exploited BlueKeep (CVE-2019-0708) to create local admin accounts, and performed DCSync replication against Active Directory.

Low-quality casino sites conceal highly dangerous threat actors

Infoblox reveals China-aligned APT groups hiding PeckBirdy malware C2 domains inside roughly 1.7 million Chinese-language illegal casino websites.

An Infoblox report says it tracks about 1.7 million Chinese-language casino sites enabling illegal gambling, some of which double as command-and-control infrastructure. China-aligned APT groups have hidden PeckBirdy framework C2 domains inside these low-quality casino sites since 2023, injecting scripts that display fake software update pages to deliver malware. Over 3 percent of Infoblox enterprise customers resolved at least one PeckBirdy C2 domain, and some sites rely on US cloud providers via 'infrastructure laundering.' Infoblox urges defenders not to dismiss casino-domain alerts as mere employee browsing violations.
