Binance Drained of $5.5 Billion in Suspected Hack, Tether and Circle Freeze $1.8 Billion

Decrypt reports that at least $5.57 billion left Binance-linked hot wallets on Ethereum, Bitcoin and Tron on 29 October 2026, which would be the largest crypto hack on record. On-chain analysts point to an EIP-7702 delegation, installed from a Tornado Cash-funded address minutes before the first sweep. Tether and Circle froze about $1.8 billion. Binance has not confirmed the hack, and how the attacker obtained the signature is unknown.

Rekt - SingularityNET - Rekt

SingularityNET exploit (19 September 2026): attackers with signing authority exposed through a cloud infrastructure breach drained 8.72M FET from the Ethereum bridge converter, then minted about 2.3 billion AGIX, NTX, WMTX and CGV. Rekt's transaction-level reconstruction puts gross liquid proceeds near $2.29M, not the $16.77M headline, and traces laundering via Chainflip, Baltex and THORChain. It notes conversionIn() skipped checkLimits() and trusted a single EOA signature.

Falcon Key Recovery from Joint Sampler Leakages

Falcon Key Recovery from Joint Sampler Leakages is an ePrint paper presenting a power side-channel attack on Falcon and FN-DSA that fuses three SamplerZ leakages (exponent class of the center, sign bit, proposal magnitude). It turns them into slab and halfspace constraints solved by softplus interval regression, with no LLL or BKZ. On PQClean Falcon-512 (ARM Cortex-M4) it recovered all 50 keys with at most 34 signatures; on c-fn-dsa it recovered 38 of 50 keys within 200 signatures.

Bitcoin Wallet Fixes Critical Flaw That Redirected Funds to Attackers

Electrum 4.8.3, released 24 October 2026, fixes a high-severity flaw in the Bitcoin wallet. Rogue servers could suppress a real payment and inject a fake unconfirmed transaction paying an attacker, so a user's fee-bump became the first transaction broadcast. The fix verifies signatures on wallet-owned inputs, but incoming transactions from external senders stay unverified. One user lost funds on 18 October.

Bitcoin wallet bug let rogue servers steal funds when users tried to speed up payments

Electrum, a Bitcoin software wallet, disclosed on 24 October 2026 a flaw where malicious servers swapped pending transactions for fake ones with invalid signatures that the wallet did not check. When users chose Replace-by-Fee to raise the fee, Electrum signed a valid replacement paying the attacker, and at least one user lost funds. Version 4.8.3 adds signature checks; users of only trusted or self-run servers were not exposed.

A Kelsey–Kohno Attack Variant against SHA-2 Message Digests in HSS/LMS and XMSS

Falko Strenzke's ePrint 2026/2635 presents a multi-target second-preimage attack on message hashing in HSS/LMS and XMSS with SHA-256 and SHA-256/192. It herds chaining states from many collected signatures into one state, defeating the key and leaf-index prefix. With 2^64 signatures, SHA-256 cost falls from 2^256 to about 2^166 (2^156 at maximal message length). SHAKE256 parameter sets are unaffected.

A hash-only rollup: OP Stack L2 accounts as Lamport-style hash chains, no ECDSA inside the L2

Hash-only rollup: an OP Stack L2 (chain ID 42069000, live since 30 September 2026) where accounts are keccak-256 hash chains and transactions carry no signatures. Spending uses a commit-reveal step through two new transaction types in op-geth. The post describes a flaw the authors found: unauthenticated commits could be overwritten, which allowed preimage front-running. It was fixed with a first-commit-wins rule on 21 October 2026.

Chosen Commitments and Certified Decoding Regions in the Adaptive Threshold Schnorr Attack

This IACR ePrint 2026/2632 paper by Demirtaş and Yayla analyses the Crites–Stewart adaptive forgery attack on threshold Schnorr signatures, which needs one call to a sparse linear search oracle (bounded distance decoding of a scaled Reed–Solomon code). It shows that choosing the commitment coefficient vector does not help much: a wrapper adversary with Q challenges succeeds with probability at most QM/p, even if its solvers decode every witness for free. For the six original (N, τ) pairs, M stays below 2^24, so the bound is under 2^-100 after 2^128 challenges at p = 2^252.

Electrum wallet security flaw is fixed after a user loses money in fee attack

Electrum 4.8.3, released 24 October 2026, fixes a flaw where a malicious server replaces a user's unconfirmed payment with a conflicting transaction carrying invalid signatures. If the user then bumps the fee with replace-by-fee, the wallet signs a payment to the attacker. One of two reporting users lost funds, and the patch now checks input signatures before accepting such transactions. Bull Bitcoin is adding the same client-side check.

Agentic AI Defense: Decode-Time Provenance Binding for MCP

Decode-time provenance binding is a defense for Model Context Protocol agent pipelines against cross-modal trust laundering, where instructions hidden in an email-signature image via LSB, DCT or metadata steganography get decoded by a tool. It combines HMAC-authenticated trust labels, a provenance ledger and context-taint tracking to block critical tool calls. On a real MCP testbed with 24 adaptive payloads, attack success fell from 100% undefended (62.5% for keyword and regex filters) to 0%.

Claude reveals ECDSA curve origins

Anthropic's Frontier Red Team reports that Claude recovered how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They are outputs of the C library's lrand48 LCG seeded with 1997–98 Unix timestamps, not hashes of a passphrase. The method scanned for weak-PRNG signatures, then used LLL lattice reduction to recover the truncated LCG state and stepped it back to srand48 initialization. Claude also traced some base points to the FreeLIP/NTL random generator. Reproducible Python is included. The authors say this is not an attack and makes deliberate backdoors less plausible.

Each SPECK round has soundness error 1/2, which inflates signatures, and the SPECK authors had warned that naively using multiple public keys creates security concerns. The authors analyse those concerns, give conditions and parameter constraints under which multiple keys can be integrated securely, and show that conservative parameters perform poorly but leave room for improvement.

Shorter Hash-Based Signatures via Guarded Sharing in a DAG Model

Proposes "guarded sharing", a technique that moves few-time signatures in SPHINCS-style stateless hash-based schemes from a tree model to a DAG model. Combined with bucket thinning, hash chains and rejection sampling, it yields BGS-CC, which improves on the prior best few-time scheme BPORS-C+BFP. For 128-bit security and a use quota of Q=2^24 it gives 2,228-byte signatures, the first SPHINCS-based stateless signature shorter than ML-DSA-44's 2,420 bytes. This matters for PQ migration because signature size is the main drawback of SLH-DSA.

MLExpert: Towards a Generalist Agentic Model for Autonomous Machine Learning Engineering

Presents MLExpert, a 35B Mixture-of-Experts agentic model trained for autonomous long-horizon machine learning engineering. Training uses a Kaggle-MLE Factory to build executable tasks and an interaction harness, hierarchical agentic SFT with outcome-guided supervision, and Windowed Interaction RL (WIRL). WIRL treats the multi-turn decisions between successive experiment results as one execution window with a shared outcome reward, and uses asynchronous collection and policy correction. On MLE-Bench Lite the average medal rate rises from 37.9% to 72.7%, comparable to larger frontier models such as Kimi-K3 and GLM-5.3. It also improves on NatureBench Lite, agent scaffold optimization and algorithm optimization.

ePrint paper presenting an NVIDIA GPU implementation of FAEST (a post-quantum signature scheme built on VOLE-in-the-Head and QuickSilver), covering key generation and OWFProve/OWFVerify for standard and EM constructions in s and f variants. Profiling shows field multiplication takes about 82% of FAEST-128f signing time once AES is hardware-accelerated. Using PTX clmad carry-less multiplication plus Karatsuba, it reaches up to 26.6x kernel throughput and about 2.9-3.1x full 256-bit OWFProve throughput over the software-multiplication build on an RTX A5000.

ERC-8443: Quantum Bridge Shield

Draft ERC from Quantova Inc proposing a "Quantum Bridge Shield" for Ethereum bridges. A committee signs the Merkle root of each message batch with RFC 8554 LMS hash-based signatures instead of ECDSA/BLS keys that Shor's algorithm can break. The guard contract requires a strict majority of distinct unfrozen keys, records used leaves, freezes any key that signs a leaf twice, binds digests to domain, chain, guard and epoch, and applies a 60-second delay. The post gives gas costs (LMS W4 height-10 verification about 205k gas, a LayerZero packet 128,683 gas, worst-case rotation 12.44M gas under the EIP-7825 cap) and cites a NioLabs assessment with no critical or high findings. It is relevant as a worked post-quantum migration design for bridge key custody, including hybrid ECDSA+LMS mode and stateful-signature pitfalls such as leaf reuse and rollback.

Presents the first blind signature in which the issuer runs unmodified NIST-standardized ML-DSA, so it works with certified secure elements. Issuance is an ML-DSA signature on a commitment. The blind signature is a VOLE-in-the-head zero-knowledge proof of knowledge of that signature, about 1 MB, under 1 s to produce and 0.5 s to verify. Security reduces to ML-DSA EUF-CMA and the proof system. Issuer-hiding and selective disclosure add a few tens of KB.

The phone Secure Element signs a verifier challenge with an unmodified FIPS 204 ML-DSA interface, and the user proves knowledge of that signature in zero knowledge at each presentation. Using ML-DSA's structure avoids the cost of generic NIZK systems such as Longfellow. The most efficient variants assume weak-MLWR for unlinkability, and that assumption can be dropped at some efficiency cost. The protocol works with different anonymous credential schemes, and a proof-of-concept implementation is included.

Coinbase, which holds 5% of all bitcoin, wants the quantum fix started now

CoinDesk summarizes Coinbase's recommendations for making Bitcoin quantum-resistant before a cryptographically relevant quantum computer (CRQC) can derive private keys from public keys. The proposals are: a transaction format that can carry new signature types (P2MR/BIP-360, P2TRv2), staged hybrid "1-of-2" spends with ECDSA/Schnorr or a post-quantum key, and stateless options alongside stateful schemes to avoid key-reuse forgery. They also ask that evaluation favor constant-time, RNG-failure-safe implementations, require MPC compatibility, and handle dormant or late-migrating coins as a separate debate. It is a useful overview of the defensive migration design space, but it is secondary reporting and not the primary Coinbase paper.

CUTS: Chained Uniform-sum Tree Signatures

The paper analyses stateful hash-based signatures whose key is a tree of hash chains, and asks what a second signature from the same one-time key reveals after state loss or rollback. It proves that the values derivable from several signatures are exactly the union of those from each signature alone. It also bounds forgery after b signatures in the classical random-oracle model by a combinatorial coverage exponent λ_b, including when the signer grinds a counter. It then introduces CUTS, a scheme on one binary tree whose chain positions sum to a fixed value S and whose signature size and verification cost do not depend on tree height. One parameter set has 1,424-byte signatures and λ_2 ≥ 128.6. A counter variant, CUTS+C, gives a proven grinding gain.

How Zcash Plans to Hide Your Keys From AI and Quantum Attacks

Decrypt reports that Zakura, which builds a Zcash full node, expects post-quantum signature opcodes in Zcash in January, to enable hash-based signatures for transparent pools. The plan rotates to a fresh transparent address after every transaction so public keys stay hidden, and adds a WOTS hash-based backup signature. Private information retrieval, shipping this week in the Vizor wallet, stops servers from linking the rotated addresses. It follows Justin Drake's "bunker mode" warning that AI-driven math could break ECDSA. The plan covers only transparent payments, and no activation date has been confirmed.

Understanding Verification Vulnerabilities in Cross-chain Bridges: An Empirical Study

First systematic empirical study of Cross-chain Verification Vulnerabilities (CVVs) in bridge smart contracts, such as flawed validation of state proofs, message sender identities and signatures. From 588 audit reports across 36 bridge projects it derives 11 CVV patterns in 5 categories and builds a dataset of 830 instances across 786 contract files, mapped to reports, source versions and pattern labels. Existing tools cover few CVV patterns, and only two of four tested LLMs beat a 29.3% Macro-F1 constant baseline (best 51.2%), which motivates detectors built for cross-chain verification semantics.

It estimates roughly 6.9 million bitcoin sit in addresses with exposed public keys (including early pay-to-public-key and long-dormant "Satoshi era" outputs) that a sufficiently powerful quantum computer could eventually use to derive private keys, and cites a 2024 study putting full UTXO migration to quantum-resistant signatures at 76–300 days of cumulative block space, with new post-quantum signatures 10–120x larger than ECDSA.

Hide Now, Trace Later: Retrospective Attribution in Issuer-Hiding Credentials

Krenn, Lesaignoux, Mir and Spini (AIT Austrian Institute of Technology) propose an "issuer inspection" mechanism for issuer-hiding attribute-based credentials (ABCs): an inspection authority can release time-bound keys that let verifiers locally flag presentations tied to a specific compromised issuer without unmasking other issuers or periods. They formalize the syntax/security model, give a generic construction, and instantiate it concretely using Groth's randomizable structure-preserving signatures, Schnorr-style proofs, and an adapted Gentry anonymous identity-based encryption scheme, showing the overhead stays practical. This addresses the accountability gap introduced when issuer-hiding ABCs conceal which authority issued a credential during verification.

This IACR ePrint paper (published TCHES 2027) presents a new cryptanalysis technique for the Lattice Isomorphism Problem that embeds LIP into a shortest-vector-problem instance on a different lattice than the one used in Hawk's specification, allowing attackers to integrate "hints" — partial information on the secret key obtained via side-channel attacks or other leakage. Using the LeakyLWEEstimator tool, the authors show Hawk signatures themselves leak exploitable information about the secret key, eroding Hawk-1024's security by roughly 11 bits, and apply the framework to resolve an open side-channel problem from TCHES 2024 plus discuss further fault-injection attack paths. Hawk is a lattice-based signature scheme submitted to NIST's second post-quantum signature call, making this a concrete key-recovery cryptanalysis relevant to PQC migration planning.

Formalization of the Invariant Duality Theorem

An Ethereum Magicians forum post formalizes an "Invariant Duality Theorem": in a permissionless network, a protocol cannot simultaneously achieve Perfect Indistinguishability (traffic statistically indistinguishable from white noise under DPI) and Resource Exhaustion Resistance (O(1) early rejection of junk packets). The proof sketch argues that indistinguishable traffic forces receivers to run expensive deobfuscation on all packets including attacker-generated noise (enabling DoS), while any cheap early-filter function, by Kerckhoffs's principle, becomes a public signature a censor can hardware-implement to block the protocol. This is a theoretical tradeoff relevant to designing or attacking covert/anti-censorship transport protocols.

Shorter Few-Time Signatures from Hash Chains and Blockwise Forced Pruning

This IACR ePrint paper introduces BPORS-C+BFP, a new few-time signature construction that replaces FORS in SPHINCS+/SLH-DSA, combining short hash chains with a blockwise forced-pruning budget to shrink the bottom signature component. The authors derive a generating-function coverage bound and an exact counting method to safely tighten pruning per block, achieving 8.3%-18.1% smaller full SLH-DSA signatures across six standard parameter sets (versus 3.7%-13.4% for the prior BPORS+FP scheme), and up to 32.5%-36.5% reduction in limited-use settings.

K-LMS: Design, Implementation, and Evaluation of Leighton–Micali Signatures with Korean Cryptographic Primitives

An IACR ePrint paper presenting K-LMS, an experimental variant of the NIST-standardized LMS hash-based post-quantum signature scheme in which the underlying hash is swapped for Korean primitives: the LSH-256 hash function (reference and vectorized) and a Tandem-DM double-block-length construction built from the CHAM, LEA, and ARIA block ciphers. The authors implement a non-invasive backend-swapping bridge over the reference LMS code and benchmark keygen/sign/verify latency, key/signature sizes, memory, and parameter sweeps, finding that hash substitution doesn't change key/signature sizes but that two measurement pitfalls (hash dispatch overhead, and software vs. hardware-accelerated SHA-256 baselines) can shift performance comparisons by an order of magnitude or 6x respectively. They report LSH-256 K-LMS signing on par with SHA-256 LMS in software, and 3.3-3.9x faster than a prior K-XMSS implementation because LMS needs fewer hash calls per Winternitz step than XMSS.

Across the six non-EM FAEST v3 parameter sets, the authors find the CPU-GPU path beats optimized CPU-only signing for single-sign latency in 4 of 6 cases (up to 1.6x speedup for FAEST-192s) and wins throughput in 9 of 18 parameter/batch-size combinations, with GPU correctness validated to match the reference signature output.

N2SF-Based Post-Quantum Cryptography Migration Framework for Data in National and Public Institutions

An IACR ePrint paper proposes PQC migration decision criteria for data held by national and public institutions, derived from South Korea's N2SF (National Network Security Framework) protection requirements and each data object's cryptographic dependencies/operational state. It distinguishes migration actions (payload retention, key rewrapping, re-encryption, communication migration, signature renewal) from execution decisions (allow/defer/deny), requiring consistent completion checks, recoverable registered copies, and current authority. A reference implementation ran 225 policy trials and 9 interruption trials, showing per-stage/completion rechecking prevented unauthorized completions or reads that occurred when reusing initial decisions, and confirmed clean resumption after interruption; institutional approval and production-scale key management remain unvalidated.

HyBind: Structural Analysis of PQ/T Hybrid Cryptographic Usage

HyBind is an intraprocedural Python static-analysis framework that traces cryptographic component secrets through code to determine whether post-quantum/traditional (PQ/T) hybrid key-derivation and signature-verification logic actually requires both algorithms to succeed, rather than silently accepting a result from only one. It uses registered API contracts and function-return/execution-effect checks to distinguish real AND-logic hybrids from presence-based heuristics that wrongly treat joint and single-algorithm contributions as equivalent. The authors validate it on 50 controlled fixtures and 33 programs (15 using native ML-KEM/X25519 and ML-DSA/Ed25519 APIs), showing relaxed checks can misclassify traditional-only results as hybrid.

Role-Specific Signature Placement in TLS 1.3: Cost Propagation and PQC Migration

Across 286 three-algorithm groups, median max/min ratios reach 2.085x for TLS handshake latency, 4.310x for certificate body size and 4.551x for path-validation cost purely from role order, with Leaf placement mattering far more than Root/Intermediate swaps. It also shows that looking only at Certificate-message size can misrank candidates such as ML-DSA-65 versus SLH-DSA-SHAKE-192s once the Leaf signature in CertificateVerify and full authentication-path cost are included, arguing PQC certificate-chain design must account for role-specific cost under real network/load conditions.

Measuring Parallel Execution of Classical–PQC Component Pairs in Hybrid TLS 1.3

An IACR ePrint paper benchmarks whether running the classical and post-quantum components of hybrid TLS 1.3 key exchange (ECDHE–ML-KEM) and Composite ML-DSA signatures in parallel on separate pthread worker threads reduces handshake latency versus sequential execution. Across three RFC 10024 ECDHE–ML-KEM groups with server and mutual authentication, parallelism sped up all six tested conditions on a standard ARM and x86 system (1.04×–1.28×), with the largest gains in signature stages where component times are balanced, but slowed every condition on a low-power x86 system (0.80×–0.92×) because thread wake/wait overhead outweighed savings. The authors conclude that component independence alone doesn't guarantee a speedup and that parallelization decisions must be validated per target environment.

Six rounds of testing surfaced concrete defects: a false negative caused by a stripped field list, a tamper-accepted body via a service-selection parameter that let callers choose which fields were excluded from the signed message, schema-rejection and signature-failure returning byte-identical error text, and a logging/privacy gap in the operator's system that was fixed after disclosure.

A Clever RSA Attack Fooled a Hardware Vault—Here's What It Means for Crypto

Researchers at UC San Diego and INRIA demonstrated a chosen-message oracle attack that forges RSA signatures on a 1,024-bit key held inside a hardware security module (HSM) without ever extracting the key, by disabling the HSM's FIPS mode to get it to sign unpadded/unformatted values roughly 4 billion times and then computing the private-key operation from the responses (1,380 CPU core-years of work). The attack only applies to unpadded RSA signing oracles — standard PKCS#1 v1.5/PSS padding blocks it — so it doesn't threaten Bitcoin/Ethereum (which use ECDSA) but is relevant to anyone auditing HSM key-custody assumptions or RSA-based blind-signature schemes like Privacy Pass. The authors frame it as further classical evidence to accelerate migration away from RSA ahead of the post-quantum transition.

Closed-World Resolution Against Tool Hallucination in LLM Agents

This arXiv paper identifies tool hallucination — LLM agents calling nonexistent tools or passing undeclared arguments — as a structural blind spot that existing tool-selection and tool-gating defenses cannot catch, since a hallucinated call was never a real gating decision. The authors propose a five-class taxonomy (H1-H5) of tool hallucination and a training-free closed-world resolver (the Resolution Rung, based on registry membership plus signature checking) that must run before any causal gate, then extend the analysis to the Model Context Protocol where merging multiple servers into one namespace creates a second hallucination class (M1-M5) from tool collisions and shadowing. Across ten hosted models they measure 322 hallucinations on single-registry tool calls and 154 on a live MCP surface, and release the versioned Hallucinated-Tools Benchmark (HTB) for comparing resolvers.

AI-Generated Malware Risk: A Practical Guide for Developers | Blog | Endor Labs

An Endor Labs guide explaining how AI-generated and AI-enhanced malware (citing Check Point's VoidLink, Google TIG's PROMPTFLUX/PROMPTSTEAL, and HYAS Labs' BlackMamba/EyeSpy) differs from traditional threats by dynamically mutating code at runtime to evade signature-based detection. It argues software supply chains are a prime target because AI can mass-produce convincing typosquatted or dependency-confused packages, and recommends behavioral analysis plus full-stack reachability analysis (via Endor Labs' AURI) as defenses instead of relying solely on CVE/signature matching.

Artifactory Under Attack: In-the-Wild Exploitation of CVE-2026-42016, CVE-2026-42018 & CVE-2026-82329

Wiz Research documents active in-the-wild exploitation of three JFrog Artifactory vulnerabilities: CVE-2026-42018 (exposes an internal anonymous-user JWT via POST /access/api/v1/aws/token/), CVE-2026-42016 (token scope validation flaw allowing that JWT to be escalated to admin via POST /access/api/v1/tokens), and CVE-2026-82329 (unauthenticated admin access via POST /access/api/v1/registry/join, added to CISA KEV). Attackers chained the first two to create persistent admin accounts, deploy malicious Groovy plugins for RCE, and drop Rust-based C2 backdoors, while CVE-2026-82329 was exploited independently for configuration exfiltration, cluster join-key theft, and credential/SSH-key persistence. The post includes exact request sequences, detection signatures, affected/fixed version ranges, and remediation guidance.

ClearFake WebDAV infection chain delivers Amatera stealer, ZigCryptoStealer, and NetSupport Manager

Cisco Talos reconstructs two related WebDAV-based infection chains (tracked actor UAT-10820) that use a ClickFix fake-CAPTCHA lure, EtherHiding on BNB Smart Chain to stage JavaScript via a malicious Cloudflare Worker, and WebDAV-delivered disguised DLLs executed via rundll32 ordinal calls to drop the Amatera stealer. Depending on the C2 configuration, Amatera then deploys either a NativeAOT-loaded ZigCryptoStealer with a BYOVD EDR-killer driver and a Go-based Yamux reverse proxy, or a PowerShell stager that installs a trojanized NetSupport Manager RAT pointed at Russian C2 infrastructure. The post details loader internals, Amatera's dead-drop C2 resolution via Telegraph and Steam, and provides ClamAV signatures plus a full IOC list.

Axonal delay dispersion decides whether a neuron detects an event or a sequence, and predicts cortical column diameter

This arXiv preprint proposes a "delay-signature" framework where the dispersion of axonal conduction delays converging on a dendritic branch determines whether a neuron acts as an event detector (coincidence) or an order-selective sequence detector, using simulations of an integrator-neuron model. The authors find a single scalar (delay dispersion) governs this computational transition, sets a millisecond-scale timing tolerance, and together with conduction velocity predicts cortical column diameter — linking myelination to what a neuron computes, not just how fast it signals.

SAST for AI-Generated Code: What Static Analysis Catches and Misses | Blog | Endor Labs

Endor Labs blog post arguing traditional signature-based SAST misses the logic and business flaws AI coding assistants introduce, since those flaws are "not pattern-shaped." It contrasts AI-assisted SAST (rules plus a thin AI layer) with AI-native SAST that traces dataflow across files and uses reachability analysis plus evidence-based triage to cut false positives, citing that Endor Labs' own tool (built on Opengrep with AI-agent triage) found a zero-day, CVE-2026-55407, in Anthropic's Rust buffa library and that only ~1 in 5 AI-recommended dependency versions are safe.

The Evolution of JFrog AI Catalog: Your AI Control Plane for Agentic Development

JFrog vendor post arguing that agentic development (ADLC) introduces new unvetted supply chains — models, MCP servers, skills/plugins, hooks, and APM packages — that bypass traditional signature-based scanning. It cites real incidents: a malicious MCP server impersonating Postmark's email MCP that BCC'd all agent-sent emails to an attacker, and the 'omnicogg' malicious Claude/agent skill that hid a 22MB encoded payload and evaded all 65 VirusTotal engines for 5,000+ installs, plus references to 2026 supply-chain attacks on LiteLLM, TanStack, and Mistral AI. It then pitches JFrog AI Catalog's expanded MCP/skill/model registries as the fix.
