FST Pay: Deterministic Safety-Gated Architecture for Youth Digital Payments

FST Pay proposes a deterministic safety-gated architecture for teen digital payments, pairing invariant authorization checks with decoupled post-settlement AI explanations.

Researchers propose FST Pay, a formal architecture for adolescent digital payments on rails like UPI that applies six deterministic invariant checks (spending limits, guardian co-sign policies, amount thresholds, merchant category codes, temporal intervals, hardware integrity) to classify transactions as ALLOW, REVIEW, or BLOCK. High-risk transactions trigger an asynchronous guardian co-sign workflow. Generative AI is restricted to post-settlement natural-language insights and holds no mutation privileges over the ledger, avoiding non-determinism on the real-time authorization path.

Signing the Transaction but Not the Decision: Whisper Attacks and a Binding Defense for AP2

Research shows AP2 agent-payment signatures can be manipulated into valid but wrong carts; proposed A-VIP defense binds signed intent to purchases.

A study demonstrates Whisper attacks on the AP2 agent payment protocol, where ordinary product-description text steers shopping agents into carts that pass every cryptographic check but no longer match user intent. Using Gemini Flash-Lite models specified by AP2's default sample agents, three attacks succeeded at 90%, 56%, and 73.3%, with the vulnerability spanning seventeen Google models, three agent frameworks, cross-vendor anchors, and Google's consumer assistant. The proposed A-VIP defense treats signed intent as a capability grant, binding credential lookups to sessions and cart lines to seen listings, blocking the first two attacks with zero false positives while surfacing unauthorized spending. The authors release A-VIP code, machine-checked invariants, and AP2-WhisperBench with 1,544 evaluation scenarios.

Securing Your Business: The Vital Role of Cyber Insurance | Huntress

Huntress explains cyber insurance coverage types, insurer security requirements, and the shift toward documented evidence of controls.

Huntress outlines first-party and third-party cyber insurance coverage, including business interruption, data recovery, extortion, privacy liability, and regulatory fines. Insurers now commonly require EDR, MFA, security awareness training, patching, tested backups, least-privilege access, and incident response plans. With ransomware accounting for 91% of insurance losses in H1 2025 and average US breach costs at $10.22 million, underwriters increasingly demand evidence packs rather than self-attestation.

Adobe Commerce max-severity bug comes under active attack

Attackers are actively exploiting CVE-2026-75650 (CVSS 10.0), an unauthenticated RCE zero-day in Adobe Commerce/Magento, deploying a Rust backdoor on e-commerce servers.

Sansec identified active exploitation of a CVSS 10.0 zero-day (CVE-2026-75650) in Adobe Commerce and Magento Open Source versions 2.4.4 through 2.4.9, dubbed StyleSmuggler. The attack abuses crafted style properties in Magento template processing to execute PHP while rendering a 'Payment Transaction Failed Reminder' email, then launches a Rust backdoor connecting to C2 at 99.84.67.186 disguised as NTP traffic. Exploitation began September 4, 2026; Adobe released emergency hotfix VULN-393411, but Sansec also observed a second attacker deploying a PHP web shell in the product-image cache.

Revolut handed customer data to fraudsters using government email account

Revolut handed sensitive KYC data of high-net-worth crypto customers to fraudsters submitting fake emergency data requests from a compromised government email domain.

Revolut confirmed it disclosed sensitive customer data—including passport and driver's license copies, verification selfies, bank statements, IBANs, and Bitcoin transaction histories—to attackers who submitted fraudulent emergency data requests from a legitimate government agency email account, apparently an Italian domain. Targets were high-net-worth individuals involved in crypto, including Marc Karpelès and entrepreneur Marc Zeller. A Telegram account claiming responsibility posted stolen data as proof and demanded an extortion payment; the account has since been suspended. Revolut says only a limited number of customers were affected and has alerted the relevant government agency, law enforcement, and regulators. The technique mirrors 2021-2022 Lapsus$-linked fraudulent emergency data request scams against Apple, Meta, and Discord.

Attacker stole a METR API key, used $600K worth of credits, and no one noticed for weeks

Attackers stole a METR API key via an exposed agent-run EC2 instance and consumed about $600,000 in public model credits over three weeks.

AI evaluation nonprofit METR disclosed two incidents. In March 2026, a fail-open bug in a vibe-coded app disabled authentication on a publicly accessible EC2 instance; an attacker prompted the running agent to reveal a model provider API key, added an SSH key for persistence, and consumed roughly $600,000 in free public-model credits over three weeks without being noticed. In May 2026, attackers probed METR's public infrastructure using agents, automated vulnerability discovery, credential stuffing, OAuth token attempts, and phishing; a separately exposed read-only SQL mechanism found by a bug bounty hunter risked leaking unpublished evaluation data, but no access to non-public data was confirmed.

Securing Claude Code: The New Compliance API, Local Visibility, and Identity Governance

Anthropic's new Compliance API endpoints expose Claude Code local session transcripts, highlighting governance gaps for endpoint AI agents.

Anthropic added local session transcript endpoints to its Compliance API on August 11, 2026, giving security teams visibility into prompts, bash commands, file operations, and MCP commands run by Claude Code harnesses on endpoints. The article argues local harnesses break the classic shared-responsibility model, citing Token Security data that 68.6% of discovered AI agents run on endpoints, and a Cloud Security Alliance survey of 418 IT and security professionals in which 82% found an unknown agent within the past year. It outlines three governance layers: Anthropic managed settings as a policy baseline, the Compliance API for cloud-visible transcripts, and endpoint telemetry to connect agent activity to identity, credentials, and permissions.

US disrupts Xinbi Guarantee marketplace fueling the cyber scam economy

US Treasury sanctions and DOJ seizures take down Xinbi Guarantee, a Telegram marketplace that processed $24B+ for cyber scams, freezing $52.8M.

The Treasury Department sanctioned the Chinese-language Telegram marketplace Xinbi Guarantee and two supporting firms, Anwen Technology (XinbiPay) and SafeW Technology, while the DOJ seized its Telegram channels and $52.8 million in USDT from 52 wallets. Blockchain intelligence firm Elliptic, which assisted the Secret Service, estimates Xinbi has processed at least $24 billion in transactions since 2022, making it the second-largest illicit online marketplace and a cornerstone of Southeast Asian cybercrime. Vendors sold money laundering, stolen personal data, deepfake technology, and other services for pig-butchering scams, with payments in Tether's USDT. The DOJ's Scam Center Task Force also dismantled 13 scam centers in Madagascar, arresting dozens of alleged leaders who were repatriated to China.

Heterogeneous Cross-Chain Transaction Tracing for Solana Bridges via Candidate-Set Selective Decision

SolTracer traces cross-chain transactions onto Solana bridges, improving open-world association F1 by 20.16% over the strongest baseline for illicit-fund tracing.

The paper formalizes four Solana-bound cross-chain transaction modes and proposes SolTracer, which maps heterogeneous execution semantics into a unified event space and uses candidate-set selective decision-making with abstention when valid targets are absent. In the challenging open-world setting with a 50% TA ratio, SolTracer improves F1 by 20.16% over the strongest baseline. An empirical study of real-world transfers examines count-value divergence across bridge mechanisms, cross-asset shifts, and decoupling between on-chain settlement and explorer visibility.

NIS2 compliance: Fixing IAM and access control before the 2026 audit

EU NIS2 enforcement deadlines approach; organizations are urged to prioritize service account inventory, lifecycle offboarding, and phishing-resistant MFA before audits.
