Check Point2 days ago10 min▣LLM reportcritical Check Point Research discovered five memory-corruption vulnerabilities in workerd, the open-source runtime underlying both Cloudflare Code Mode and Cloudflare Workers. Two were rated Critical by Cloudflare: a use-after-free in node:zlib's deflateParams() and a use-after-free in HTMLRewriter's AttributesIterator. The researchers demonstrated two end-to-end exploits: a cross-tenant secret theft via a URLPattern out-of-bounds read on the shared tcmalloc heap (bypassing V8 sandbox and MPK), and a Code Mode sandbox escape from prompt injection to native host RCE via the zlib UAF. All bugs operate on the tcmalloc native heap, which is explicitly outside the V8 sandbox cage and memory protection keys. Cloudflare's managed environment is patched; self-hosted deployments must update to workerd v1.20260619.1. No CVEs have been assigned.

#0006Check Point27 days ago5 min▣LLM reporthigh The Check Point Research AI Security Report 2026 highlights the transition of AI from an attack assistant to a live attack operator. Threat actors are now using AI to build deployment-ready malware, run live intrusions, and scale social engineering attacks using forged virtual identities. The report also notes a significant rise in indirect prompt injection attacks and persistent enterprise data leakage through GenAI applications.
#0007Check Point27 days ago9 min▣LLM reporthigh This weekly threat intelligence bulletin covers multiple significant incidents including autonomous LLM-driven ransomware (JadePuffer), a cryptocurrency supply chain compromise via malicious npm packages, and three critical CVEs affecting Langflow, Tenda routers, and Linux KVM. Iran-linked Cavern Manticore and China-linked UAT-7810 were profiled targeting Israeli and networking infrastructure respectively. The report also highlights risks in AI development tools where hidden malicious instructions in open-source files could achieve RCE through Claude Code and OpenAI Codex.
#0008Check Pointabout 1 month ago13 min▣LLM reporthigh Cavern Manticore, an Iran-MOIS-linked APT group, deploys a modular .NET C2 framework targeting Israeli government and IT organizations. The framework uses three compilation formats (Mixed-Mode C++/CLI, NativeAOT, .NET Framework) as an anti-analysis layer, with DLL sideloading via WinDirStat.exe for initial execution. Post-exploitation modules provide DPAPI decryption, LDAP brute-forcing, SQL browsing, network reconnaissance, and SOCKS5 tunneling, with C2 traffic XOR-encrypted over HTTPS/WebSocket channels.
#0009Check Pointabout 1 month ago10 min▣LLM reportcritical This weekly threat intelligence bulletin covers multiple active ransomware campaigns, four critical vulnerabilities under active exploitation, and emerging AI-driven threats. Notable items include actively exploited RCE flaws in Oracle E-Business Suite and Progress Kemp LoadMaster, a Citrix NetScaler memory disclosure flaw exploited within 24 hours of disclosure, a North Korean supply-chain campaign (PolinRider) deploying 108 malicious packages, and a proof-of-concept browser-native ransomware generated by an LLM abusing Chrome's File System Access API.
#0010Check Pointabout 1 month 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.
#0011Check Pointabout 1 month 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.
#0012Check Pointabout 2 months ago5 min▣LLM reportcritical This threat intelligence report highlights recent data breaches involving third-party vendors, emerging AI threat vectors such as prompt injection and WebSocket abuse, and active exploitation of critical vulnerabilities in Fortinet, Cisco, and Splunk products.

#0013Check Pointabout 2 months ago7 min▣LLM reporthigh A threat actor is distributing Rust-based cryptocurrency clipboard hijackers for Windows and macOS by disguising them as trading bots and game predictors. The campaign leverages extensive social engineering, utilizing 'Ghost Networks' to artificially inflate engagement metrics across GitHub, SourceForge, YouTube, and VirusTotal to establish false credibility. The malware achieves persistence and continuously monitors the victim's clipboard to replace legitimate cryptocurrency addresses with attacker-controlled wallets.
