Supply chain attacks leave a signal trail in credential intelligence before malicious code fires — usually days to weeks before breach day. The Polymarket incident ($2.9M, June 26) is a documented case study: compromised vendor → stolen CI/CD tokens → malicious JS injected to frontend → $2.9M drained while everything looked normal to users. We mapped each precursor signal and the monitoring layer that catches it: [https://relayshield.hashnode.dev/how-relayshield-would-have-caught-the-polymarket-attack-before-it-cost-2-9-million?utm_source=hashnode&utm_medium=feed] #threatintel #supplychain #defi #infosec #cybersecurity

Crypto Shield Mobile is now live on the Solana dApp Store. It includes read-only wallet security monitoring (Solana, EVM, TON, BTC, XRP), address poisoning detection, NFT drainer/scam detection, and criminal-Telegram-sourced threat intel.

This release adds Mobile Wallet Adapter connect. Never asks for a seed phrase or private key — it's watch-only by design.

UNC4221 / UAC-0185 (Russia-aligned) has been silently reading Telegram, WhatsApp, and Signal messages via fake device-linking QR codes since 2022. Confirmed active June 2026. Attack chain: phishing message → fake device-link page → attacker's device linked → silent real-time message copy. No alerts, no notifications. IOC set from CERT-UA#12414 (32 indicators) ingested in RelayShield TI corpus. Check your linked devices now.

425,000+ rug pulls detected. 54% of all crypto threats. A rising chart and a loud Telegram community are not signal — they're part of the attack.

AI-generated phishing now delivers 53% of crypto scam attempts via email. Your inbox is the primary vector, not Discord or Twitter.

11.1 million devices infected with infostealers in 2025. 3.3 billion credentials now circulating in criminal markets. Vidar surged to 73% of infected hosts by early 2026. Lumma dropped to 1.1%. The ecosystem rotates tools faster than detection catches up. MaaS entry point: $60/month. Less than most SaaS subscriptions. The ransomware connection that gets overlooked: stolen VPN/RDP credentials are how attackers enter the perimeter as legitimate users, weeks before the payload fires.

Shipped today: RelayShield's AI-agent security checks are live as an MCP server on Hugging Face including MCP server risk, prompt-injection breach detection, agent framework CVE monitoring, and bulk agent-identity risk scoring. Same "Agentic Attack Surface" thesis behind our AgentCore/x402 work: security built for how agents actually get compromised, not humans.

New from RelayShield: four #AIsecurity checks for agents built with smolagents, published as an MCP server on @huggingface.

MCP server reputation check before your agent connects
Prompt-injection pattern detection on ingested content
Tech-stack CVE monitoring (covers agent frameworks themselves — Langflow's CVE-2025-3248 was the initial-access vector in the first documented autonomous-agent ransomware op)
Bulk identity-risk scoring

An AI agent on AWS Bedrock AgentCore just autonomously found and paid for one of our security APIs via Coinbase's x402 Bazaar. Real on-chain payment, zero custom code, verifiable tx:

0x1cb95ce37d54201b4def745269c42790fdb9bc7255f102aa648cf6f91fab0e3a (Base)

As agents start transacting autonomously, they become an attack surface. We built the security layer to be agent-native too witih 23 endpoints now agent-discoverable + payable.

Remus Stealer: new MaaS infostealer, $250-$1,000/mo tiers, Lumma-derived code, ships with Google OAuth cookie restoration (regenerates session access even after a password change). Streams stolen logs straight to Telegram.

For the DeFi/prediction markets folks here:

We ingested the full UNC4221/UAC-0185 IOC set (June 2026 bulletin — 32 indicators, CERT-UA#12414) and launched a free public badge endpoint that DeFi protocols can embed to show live credential-layer risk status.

`https://api.relayshield.net/v1/badge?domain=example.com`

The credential/supply chain attack vector is real, it's active, and it's unmonitored by most DeFi security tooling.

We've been quietly building a threat intel API for MSPs and security teams.

Current corpus: 600K+ IOCs, 1,000+ malware families, 17 live feeds (C2IntelFeeds, Feodo Tracker, PhishTank, criminal Telegram channels).

New this month: identity graph correlation from criminal dumps, ransomware victim signals, NHI/token exposure detection, GitHub secret scanning.

REST API, n8n node, MCP server. Free IOC lookup at api.relayshield.net/developers

We checked 24 DeFi/fintech/prediction-market brands for lookalike domains: 341 found, registered and resolving right now. Only 1 is currently blocklist-flagged. That's a floor, not a ceiling: blocklists catch domains after they're weaponized, not before. We cross-check registration age + TLS cert issuance timing instead. That's the leading indicator.

If one of your AI agents leaked its LLM API key tomorrow, the first signal you'd get is the bill. No endpoint compromised, so EDR sees nothing. No anomalous login, so the SIEM sees nothing. No data left, so DLP sees nothing. Sysdig measured $46,000/day from compromised Bedrock creds. We match 19 key formats across 14 providers, including DeepSeek, Qwen and Moonshot, which most scanners miss entirely. Free check, no API key: https://blog.relayshield.net/your-ai-agents-have-credentials-someone-is-already-looking-for-them #LLMjacking

We searched public GitHub for AWS keys leaked against a domain. 4,240 hits. The top five results: a docs table, a literal AKIA.... placeholder, a redaction tool's own README, a link list, and a domain allowlist. Five out of five. Not one contained a credential. Any scanner that treats a search hit as a finding calls all five a CRITICAL exposure. Free local scanner, MIT: #infosec #devsecops #appsec #opensource

MFA worked, so attackers stopped attacking it. Two stealer families this month, same shift: don't beat the login, occupy the session after it. One drives a real browser on an invisible desktop on the victim's own machine. Impossible-travel, device fingerprinting, behavioural scoring all pass honestly. Password = delivery mechanism. Session cookie and cloud token = payload. #infosec #threatintel

12.08M autonomous agent payments last month. Average: $0.0635. At six cents nobody approves anything. The agent finds a service, gets a 402, signs, pays. Nothing in that flow checks who received the money. x402 verifies the payment and has no opinion on the recipient. A correct payment to a drainer is still a correct payment. https://blog.relayshield.net/your-agent-has-a-wallet-nothing-asks-who-it-is-paying #infosec #AIagents #x402

12.08 million autonomous agent payments in 30 days, averaging $0.0635. At six cents a call nobody approves anything, and nothing in the x402 flow checks who received the money. Measured network data and the five counterparty checks that close the gap.

Anthropic: infostealers stole Claude login sessions and drained user usage. Not LLMjacking. That is API key theft, fixed by rotating the key. This is session cookie theft, and per Anthropic the attacker may skip password and 2FA entirely. Change your password on an infected machine and you just minted them a new cookie. Clean first, revoke second, rotate third. [https://blog.relayshield.net/this-is-not-llmjacking-and-rotating-your-key-will-not-fix-it]

Replying to

@eduzsh@mastodon.social That is a better way to put it. The approval step was doing identity work nobody wrote down, so nothing looked like it was removed. The first check we'd add is not wallet screening. A fresh scam has a clean address by definition. It should be the service entry: registered days ago, name one character off something popular. Typosquatting a discovery listing is the cheapest attack in this ecosystem and nothing currently stops it.
