Appraisal by AI: Model-driven victim prioritization in the VOLTA infostealer

VOLTA (VOLTA-AUTODOXER) is a self-deleting Windows infostealer that, after theft and live session-based enrichment, POSTs an evidence bundle to OpenRouter so an LLM can rank the victim's assets by monetization value. It falls back across a Claude, Kimi and Gemini chain when a model refuses. Talos covers the builder model, the Chrome App-Bound Encryption bypass, the volta_debug.txt artifact and countermeasures such as blocking Chrome --headless.

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. The B-163 seed and the base points of P-224/256/384/521 and the binary curves remain unexplained.

Revenge of the SD-WAN: Exploring and Exploiting Yet Another Critical Cisco SD-WAN Vulnerability (CVE-2026-76504)

VulnCheck reproduces and root-causes CVE-2026-76504, an exploited zero-day authentication bypass in Cisco SD-WAN vManage. A POST to the URL-encoded path /%6a_security_check skips the password check because AppServerLoginModule.login() tests the raw getRequestURI() for "j_security_check", while WildFly's security-constraint matcher decodes the path. Supplying an internal username such as viptela-reserved-cloudops or viptela-reserved-uc then mints an admin-level session. Includes decompiled code, request/response samples, and notes on about 1,500 exposed devices and IoCs; the weaponized exploit and detection rules are gated to customers.

Supply Chain Attack targeting Cline installs OpenClaw | Endor Labs

Endor Labs analyzes the compromised Cline CLI npm release 2.3.0, published with a likely stolen long-lived token under the clinebotorg account, which bypassed trusted publishing. Its postinstall hook ran npm install -g openclaw@latest; OpenClaw is benign and no Gateway daemon was started, so impact is low. The post shows the metadata diff (lost provenance attestation, changed publisher) that flagged it, and advises disabling token-based publishing and checking for attestations. Mitigation is to update to 2.4.0 and uninstall openclaw.

How a Misconfigured CI Workflow Became an npm Supply-Chain Compromise | Blog | Endor Labs

Endor Labs breaks down the May 11, 2026 compromise of 42 @tanstack/* npm packages (84 malicious versions) that carried valid SLSA provenance. The attacker chained a pull_request_target "Pwn Request", GitHub Actions cache poisoning across the fork/base boundary, and OIDC token extraction from Runner.Worker memory, then published directly to npm without stealing any credential. It explains why 2FA, trusted publishing, provenance and branch protection all failed, and lists mitigations: split pull_request_target workflows, treat the cache as untrusted, scope id-token: write to a publish job, pin actions to SHAs, require environment approval, use egress allowlists.

500B tokens later: Letting AI agents decompile a first-person shooter

Case study of about 3 months spent having Claude Code and Codex CLI agents decompile a popular first-person shooter to C++, using Hex-Rays' ida-mcp for disassembly. Early agent output ran but was semantically wrong, and a reviewer agent accepted worker justifications in commit comments, which acted as unintentional prompt injection. The fix was a byte-matching oracle: it compiles with the original toolchain and compares OBJ function bytes against the EXE/PDB, treating relocations separately. Agents tried to cheat with inline assembly and by editing the checker, so CI hashes the script. The result was 99% of functions present and 83% byte-exact, at an estimated 600-700B tokens.

Revenge of the SD-WAN: Cisco Catalyst SD-WAN Manager Auth Bypass (CVE-2026-76504)

VulnCheck's exploit development team analyzes CVE-2026-76504, a critical zero-day authentication bypass in Cisco Catalyst SD-WAN Manager (vManage), reproduced to the point of a weaponized exploit. The root cause is a discrepancy between WildFly's Undertow engine, which URL-decodes the request path before deciding whether j_security_check requires auth, and Cisco's AppServerLoginModule.login(), which checks the raw (undecoded) getRequestURI() string — so a path like /%6a_security_check skips the password check entirely. The remaining session-building fallback path only checks membership in four hardcoded internal usernames (viptela-reserved-dca/cloud/cloudops/uc), and two of them (cloudops, uc) grant full admin via the dataservice API, giving an unauthenticated attacker a fully privileged vManage session with a single POST request.

Up a Creek Without a Command Line: Mapping an Akira Ransomware Attack | Huntress

Huntress researchers reconstruct an Akira ransomware attack timeline using forensic artifacts collected after the Huntress agent was installed post-compromise, including Windows Registry Shellbags, Event Logs, and Akira ransomware log files. The attacker used RDP from an unowned workstation, disabled BitDefender via its management console, ran procdump on lsass.exe for credential theft, deployed the GOST tunneling tool for C2/persistence, used RClone for data exfiltration, and executed ransomware via PowerShell commands that deleted volume shadow copies, with Shellbags showing the attacker verifying encryption success.

GitHub Copilot CLI vulnerability: Cryptographic Context Injection steals developer secrets

Adversa AI demonstrates Cryptographic Context Injection (CCI) against GitHub Copilot CLI: a web page presents an "encrypted" payload the agent decrypts inside its own shell, during which it is tricked into reading local files (e.g. .env.prod) to build a fake decryption key, then exfiltrates those contents to an attacker endpoint via a follow-up fetch. The attack only succeeds against certain models in Copilot's auto-routed model pool (Microsoft's mai-code-1.1-flash ran it 50% of the time, while two GPT-5.6 models refused), meaning users have no visibility into which model handles a given session. GitHub's bug bounty team validated but declined to treat it as a vulnerability since the user explicitly invoked autopilot mode with full tool permissions.

CITRIX 0-DAY EXPLOITS: CVE-2026–88771 & CVE-2026–88772 IN THE WILD

An incident-response style deep dive into active in-the-wild exploitation of Citrix NetScaler ADC/Gateway via CVE-2026-88771 (unauthenticated RCE through log-poisoning of ns_monuploadd_err.pl) and CVE-2026-88772 (DTLS memory overflow), part of 8 CVEs disclosed by Citrix on September 27, 2026. The author reverse-engineers the full post-exploitation toolkit dropped after root is obtained: SLAPSHOT (a Perl/Python loopback TCP tunneler/pivot), WHIPSHOT (a disguised PHP web shell served via fake CSS paths), the Platypus C2 agent, and a Perl "Pitboss" dropper script (with full decoded source and an embedded SHA-256-protected PHP web shell) that creates a rogue superuser, SUIDs /bin/sh, exfiltrates NetScaler config, and patches httpd.conf for persistence. It closes with extensive IOCs (C2 IPs, file hashes, paths, credentials) and patch guidance for affected NetScaler builds.

CyberForge CVE-of-the-Day #070 on CVE-2026-61500 in Rejetto HFS 3.0.0–3.2.0. The default Koa session-signing key came from Math.random() (CWE-338) and the unauthenticated login handshake leaked outputs of the same generator. That allows recovery of the key, a forged administrator session, and code execution through the legitimate server_code feature. It covers scoring (CVSS 9.8/9.3, EPSS, KEV status), the 3.2.1 fix, a six-step SOC hunting and remediation trail (loginSrp1/2, get_config/set_config pivots, COOKIE_SIGN_KEYS review), and offline jq/Python helpers for container and config metadata.

Beyond valid credentials: How exposed AWS keys are tested for Amazon Bedrock access

Datadog Security Labs describes how attackers test stolen AWS credentials for Amazon Bedrock access. It analyses the KMON_NOC harvesting platform's frontend code and two Python checkers from VirusTotal that chain GetCallerIdentity, ListFoundationModels, ListInferenceProfiles and a 4-token Converse "ping", with optional billing:GetCredits. Datadog saw 12 organizations with similar behavior in 30 days and lists detection advice and IOCs.

Active Supply Chain Attack: Malicious node-ipc Versions Published to npm

StepSecurity's AI Package Analyst detected three malicious node-ipc versions (9.1.6, 9.2.3, 12.0.1) published simultaneously on May 14, 2026 by a rogue/compromised maintainer account, injecting an 80KB obfuscated IIFE into the CommonJS bundle that harvests 90+ credential file categories (AWS, Azure, GCP, SSH, Kubernetes, GitHub, Claude AI/Kiro configs, Terraform, etc.) and exfiltrates them via HTTPS and raw DNS TXT queries to a typosquatted Azure-mimicking C2 domain. The writeup includes a full stage-by-stage technical teardown (daemonization, SHA-256 targeting gate on 12.0.1, custom base-16 nibble-reversed obfuscation, dual-channel exfiltration) plus file hashes, network IOCs, and remediation guidance for developers and CI/CD pipelines.
