Ray Serve LLM on GKE: Major performance gains

🚀 Developers using Ray Serve for LLM inference on Google Kubernetes Engine (GKE) now get significantly better performance thanks to a joint effort with Anyscale. Three architectural changes — HAProxy integration for internal routing, a direct token streaming path, and a v2 Ray executor backend for vLLM — reduce overhead and latency. Benchmarks on A4 VMs with NVIDIA HGX B200 hardware show up to 5x higher throughput and 8x lower latency, while preserving Ray's developer-friendly features.

Attackers exploit trusted AI platforms and ads

🔐 Threat actors abused trusted services — Google Ads, GitLab Pages, and Claude’s shared-chat feature — to trick developers into executing malicious PowerShell and terminal commands via ClickFix social engineering. Researchers at TrendAI observed a six-wave campaign that funnelled over 2,000 victims from sponsored search results to malicious pages and then to weaponized Claude shared chats. By impersonating popular developer tools and brands, the attackers leveraged reputation stacking to make their lures appear legitimate and evade detection.

Apple patches Beats Studio Buds eavesdropping flaw

🔒 Apple released a security update to fix a high-severity vulnerability in Beats Studio Buds that could let attackers within Bluetooth range listen through an unpaired device's microphone. The flaw (CVE-2025-20701) was found in Airoha SoC open-source code and disclosed by ERNW researchers at TROOPERS. Apple deployed Beats Firmware Update 1B211, which installs automatically when paired and in range; users can verify the firmware via Bluetooth settings. Chained with related CVEs, attackers could hijack HFP connections to issue phone commands or access contacts, though practical attacks are complex and require proximity.

Telegram admits limits detecting exam leak channels

📄 India's government told the Delhi High Court that it warned Telegram roughly two weeks before blocking the app amid allegations channels were selling leaked NEET-UG 2026 exam papers. The Ministry of Electronics and Information Technology and the National Testing Agency identified groups, channels and bots circulating stolen material and reported them to Telegram. The affidavit says Telegram acknowledged limited proactive detection and relied on reported content, while India's block—initially framed as a measured step—remains in effect pending the court's ruling.

Spyware embeds forbidden text to foil AI analysis

🛡️ At least one malware author is inserting large comment blocks with policy-triggering content about nuclear and biological weapons into JavaScript payloads to disrupt AI-driven analysis. The decoy text sits inside comments so execution is unchanged while early-stage LLM-based triage can be confused or refuse to process the file. Traditional detection methods like YARA rules, entropy checks, and deobfuscation remain effective. This tactic targets naive pipelines that expose untrusted file starts to language models.

New PCI Rules Force Runtime Script Controls

🔒 An independent PCI assessor evaluated Reflectiz against the updated PCI DSS requirements and found it effectively supports merchant compliance. Modern checkouts load many third-party scripts, any of which can be turned into skimmers, and PCI DSS v4.0.1 introduces controls to inventory, authorize, and detect tampering of payment-page scripts. The QSA highlighted Reflectiz’s behavior-based detection, agentless deployment, and one-click QSA-ready evidence as key strengths, while SAQ A exemptions remain limited for iframe integrations.

Automating Disassembly with Local AI Agents

🛠️ This blog demonstrates using AI agents to automate a VB6 disassembler by exposing its parsed model through the Windows Running Object Table and providing an operator briefing plus auto-generated prototypes. The agent (Claude Code in the examples) binds to the COM object, runs scripts to extract P-code, reconstruct source, generate call graphs, and export function metadata to SQLite, all locally without uploading binaries. The approach decouples tool features from fixed menus, enables repeatable exhaustive analysis, and preserves sensitive data on the analyst's workstation.

NCSC: 75% of CNI Incidents Linked to Hostile States

🛡️ Richard Horne, CEO of the UK National Cyber Security Centre, told the RUSI Annual Security Lecture that three-quarters of cyber incidents affecting UK critical national infrastructure over the past year were traced to nation-state actors or hostile states. The NCSC handled around 200 incidents between June 2025 and May 2026, with threats described across three contested digital spaces: far, mid and near. Horne warned that AI and cloud supply-chain exploitation increase attacker scale and urged organisations to prioritise continuous defence, fix legacy vulnerabilities and close IT-OT knowledge gaps.
