Check Point6 days ago11 min▣LLM reporthigh This weekly threat intelligence bulletin highlights multiple active exploitation campaigns targeting network infrastructure (Cisco SD-WAN, Ubiquiti UniFi OS, FortiGate firewalls) and AI platforms (Dify, Langflow), alongside supply chain attacks against Polymarket and AI agent ecosystems. Notable emerging threats include EvilTokens phishing-as-a-service abusing device-code authentication for M365 token theft, the FortiBleed campaign converting 430,000+ firewalls into credential stealers, and Turla's StockStay espionage malware targeting Ukrainian entities. Cloud extortion group FulcrumSec and the DCloud Uni-App fraud framework (236,493+ scam domains) represent additional significant threats requiring defensive attention.
NEW#0813Check Point6 days ago10 min▣LLM reporthigh Check Point Research identified a DeepSeek-attributed malicious Python Flask sample that transforms a theoretical browser ransomware risk into a practical attack using the File System Access API. The sample, disguised as a Discord avatar AI upscaler named InfernoGrabber v9.0, leverages social engineering to trick users into granting folder-level file access via browser permission prompts. Once access is granted, the web page can enumerate, read, exfiltrate, and encrypt files in the selected directory — all without installing a native payload or exploiting a browser vulnerability. The technique is particularly dangerous on Android where Chrome 132+ exposes the File System Access API to web content, allowing access to high-value photo directories including DCIM.

Akamai6 days ago9 min▣LLM reportmedium The upcoming MCP 2026-07-28 specification fundamentally reshapes the protocol's security model by moving to a stateless architecture, eliminating protocol-managed sessions, and mandating OAuth 2.1 with PKCE. While this removes historical attack vectors like session hijacking and unsolicited server prompts, it introduces new risks: client-controlled state objects and tracking IDs enable cross-agent workflow hijacking, the _meta object allows metadata-based privilege escalation, new HTTP headers create desync and data leakage opportunities, MCP Apps bring stored XSS into AI interfaces, and asynchronous tasks introduce resource exhaustion DoS vectors. Security responsibility now rests squarely on MCP server developers and platform operators to implement cryptographic state verification, input validation, output encoding, and resource quotas.

AI Attacked and Abused While Perimeter Authentication Collapses
The month's defining shift was the emergence of AI as a two-sided battlefield: organizations deployed AI tools faster than they secured them, while attackers weaponized the same technology against defenders. Critical flaws in LangGraph allowed SQL injection chained to remote code execution, M365 Copilot could be turned into a one-click data exfiltration weapon via SearchLeak, and Langflow was exploited to deploy cryptominers. Meanwhile, the ongoing Shai-Hulud campaign injected prompts to blind AI malware scanners, macOS.Gaslight turned prompt injection against human analysts, and Russia's APT28 began experimenting with LLM-integrated malware. At the same time, perimeter authentication collapsed at scale: FortiBleed exposed credentials for over 73,000 FortiGate firewalls, CVE-2026-50751 let attackers bypass Check Point VPN authentication entirely, and ShinyHunters exploited an Oracle PeopleSoft zero-day across over 100 organizations.
Supply chain attackers followed developers to their new AI tools, compromising the ecosystems where code is written and built. The Shai-Hulud/Miasma worm expanded from npm into PyPI and injected persistent backdoors into AI coding assistant configurations, while North Korea's Sapphire Sleet compromised over 140 Mastra npm packages to steal cryptocurrency wallets, and the ongoing GlassWorm campaign pivoted to WebAssembly malware in VS Code extensions using the Solana blockchain as command-and-control. Social engineering also industrialized: the ErrTraffic framework turned ClickFix deception into a Malware-as-a-Service operation with blockchain dead drops, and EvilTokens hid phishing flows inside browser-side encryption to defeat network scanners while hijacking Microsoft device-code authentication.
Organizations should treat AI deployments as untrusted perimeter assets—restrict their network access, audit third-party skills and extensions, and assume prompt-injection attacks will target both automated scanners and human analysts. Every internet-facing VPN, firewall, and edge appliance should be patched immediately, with credentials rotated and phishing-resistant MFA enforced, because perimeter authentication failures now cascade directly into internal network compromise.

Legitimate Tools Hijacked as AI Becomes the New Battleground
The most damaging intrusions this week didn't rely on custom malware — they hijacked the legitimate tools and protocols organizations already trust. FortiBleed harvested real credentials from FortiGate firewall configurations worldwide, EvilTokens bypassed multi-factor authentication by abusing Microsoft's own device login flow, and a WhatsApp campaign installed legitimate ManageEngine remote management software to maintain persistent access.
Simultaneously, attackers are learning to manipulate the AI systems defenders increasingly depend on. The macOS.Gaslight malware feeds fake error messages to AI analysis tools to blind security analysts, malicious skills on the OpenClaw marketplace trick AI assistants into executing harmful commands, and researchers demonstrated that chatbot reconnaissance can map an organization's defenses through casual conversation.
Reset all FortiGate and VPN credentials immediately, scrutinize AI marketplace add-ons before installation, and assume that any legitimate-looking login prompt or remote management tool could be an attacker wearing a trusted disguise.
