Beware of Agentic Botnets: Scalable Untargeted Promptware Attacks via Universal and Transferable Adversarial HalluSquatting
Researchers from Tel Aviv University, Technion, and Intuit (including Ben Nassi and Stav Cohen) introduce 'HalluSquatting' (adversarial hallucination squatting), a technique in which attackers identify trending resources, predict the resource identifiers that LLMs tend to hallucinate, and preemptively register those hallucinated resources (repos, skills, URLs). When agentic LLM applications hallucinate and call these attacker-controlled identifiers, the technique achieves remote tool execution and remote code execution at scale, enabling scalable, untargeted promptware attacks that could form an agentic botnet without any direct channel to the target.

ContextLeak: Exfiltrating LLM Agent Context via Malicious Tools
ContextLeak is a malicious-tool attack developed by researchers at Duke and Stanford that induces an LLM agent to both select an attacker-published tool and disclose its runtime context (user prompt, conversation history, tool list) as tool input arguments for exfiltration. The attack crafts the tool's name and description using a reinforcement-learning-fine-tuned attack LLM with novel reward functions, and is shown to generalize across victims whose contexts differ from the shadow-user training data.

An Evaluation of Data Leakage Risks in Tool-Using LLM Agents in Realistic Scenarios
Research covered here, including a joint Singapore/Korea AI Safety Institute evaluation (arXiv:2606.17114) of tool-using LLM agents across 12 realistic non-adversarial tasks, found that none of three tested agents achieved fully correct and safe execution, with successful task completion often coinciding with data-handling failures like accessing unnecessary information or disclosing data to inappropriate recipients. A companion empirical study (arXiv:2604.03070) analyzed 17,022 skills from the SkillsMP marketplace and identified 520 skills with 1,708 credential-leakage issues, finding 89.6% of leaked credentials immediately exploitable and debug logging fed into LLM context windows to be the dominant exposure vector.

Black Hat 2026: AI Agent Framework Flaws Expose Secrets
Check Point researchers Shahar Tal and Yarden Porat presented at Black Hat 2026 an audit of major AI agent frameworks — LangChain, CrewAI, Microsoft Agent Framework and Google's ADK — uncovering 21 findings across eight codebases including 12 CVEs. The flaws are classic vulnerability classes (unsafe deserialization, SSRF, SQL injection, sandbox escape, arbitrary file read, memory corruption, PDF-parser RCE) reachable via post-injection exploitation, where attacker-controlled content poisons an agent's memory and triggers the framework's own internal plumbing to steal credentials and data without calling dangerous functions directly.

TrustShiftProbe: Characterizing, Benchmarking, and Defending Staged Trust Attacks on MCP Servers
TrustShiftProbe is a research framework characterizing 'TrustShift', a server-side attack where a compromised MCP server behaves benignly during a conditioning phase to build agent reliance before switching to an adversarial payload once a trust threshold is reached, evading pre-deployment static analysis. The paper introduces a temporal threat model, a language-agnostic attack engine instantiating nine variants across four domains, and 'Shield', a runtime defense at the MCP transport boundary; attacks reach a 69.5% mean success rate that Shield reduces to 42.7%.

Deterministic Frontier-Scale Language Model Inference with Signed Receipts.
A whitepaper by Aishwary Singh ("Deterministic Frontier-Scale Language Model Inference with Signed Receipts") describes a protocol that produces byte-identical outputs from frontier-scale LLM inference and binds each output to an offline-verifiable Ed25519-signed CBOR receipt, with a probabilistic spot-check verifier that re-executes samples and rejects on mismatch. The construction runs across NVIDIA H100 and AMD MI300X hardware and is aimed at giving issuer-independent fabrication soundness for AI inference at production cost.

SkillSieve: A Hierarchical Triage Framework for Detecting Malicious AI Agent Skills
SkillSieve is a hierarchical triage framework for detecting malicious AI agent skills—packages that combine natural-language SKILL.md instructions with executable code and inherit an agent's filesystem, credential, and network access. The framework layers recall-oriented regex/AST/metadata triage, four parallel LLM security sub-tasks, and a three-model debating jury, reaching F1=0.929 across 49,592 real ClawHub skills, a 390-skill benchmark, and 100 adversarial samples; code, labels, and results are open-sourced. Related audits (Snyk's ToxicSkills) reportedly found 13.4% of scanned skills contained critical issues including malware, prompt injection, and credential exfiltration.

LLM with a Surprise: A Hidden Backdoor in the Model Weights — Attack Techniques & Methods
Fabian Mosch of MSec Operations demonstrated a supply-chain attack in which open-weight LLMs (Qwen2.5-Coder-1.5B and 7B-Instruct) are fine-tuned to behave normally but trigger hidden malicious behavior when presented with specific context, embedding the backdoor directly in model weights rather than a separate loader. One PoC covertly injects extra commands into generated code, while another activates on agent tool-calling context and launched calc.exe via OpenCode on Windows; testing showed Microsoft's llm-backdoor-scanner only detects the backdoor when the triggering tool context is known. Both backdoored models were publicly released as research PoCs. Details →First reported · updated · 7 reports paloaltonetworks.com
Phantom Squatting: AI-Hallucinated Domains as a Software Supply Chain Vector

Hollow-LLM Attack: Computationally Trivial Weights in Zero-Knowledge Verification of LLM Inference
A paper accepted to IEEE S&P 2026 introduces the Hollow-LLM Attack, in which a dishonest LLM provider embeds 'ghost weights' whose algebraic structure collapses effective computation while retaining the declared architecture and parameter count. Such witnesses satisfy zero-knowledge (ZK) inference verification circuits and yield valid proofs, letting a provider serve outputs at small-model cost while overclaiming model size, exposing an 'effort gap' where proof of correct inference is not proof of large-model execution.
