Huntress analyzes Entra sign-in and audit logs from the ConnectWise Cloud Backup credential abuse of 15 October 2026 to judge whether a script, a person or an LLM agent drove it. It found a thread-pool spray, trial-and-error credential planting with a retry added within 55 seconds, and pilot-then-batch targeting. Huntress rates LLM involvement low to medium on its own data and medium to high with Microsoft's Storm-0940/ARTEX attribution. It ends with detections for service principal role self-assignment and vendor app baselining.

It gives concrete file paths and artifacts attackers hunt for (~/.aws/sso/cache OIDC tokens, Azure accessTokens.json, GCP credentials.db/access_tokens.db, GitHub gh hosts.yml and SSH keys, GitLab Runner config.toml, OpenAI/ChatGPT session cookies, and Claude Code's ~/.claude/.credentials.json OAuth tokens), plus stats: three malware families cause 85.7% of incidents, AWS/GCP account for 46%/13% of stolen secrets, GitHub ~10%, AI platforms ~5%. It also covers CI/CD-targeting infostealers (Miasma, TeamPCP) and session-cookie hijacking as an MFA bypass technique.

Hands-on walkthrough of Eyesharvester, an open-source recon tool (github.com/Exhunterx/eyesharvester) that scans IP ranges to fingerprint IP cameras, DVRs and NVRs, tests default credentials, lists vendor-specific CVEs and generates a hardening checklist. The piece demonstrates finding Hikvision devices vulnerable to CVE-2021-36260, which gives shell access and can be chained with a Metasploit payload and a reverse SSH/Meterpreter proxy to pivot into the internal network.

Rapid7 previews collaborative research with Zimbra that uncovered over 50 vulnerabilities in the Zimbra Collaboration Suite, several of which let attackers impersonate senders without credentials, control inbox visibility, and alter shared documents and calendars, turning classic Business Email Compromise into active manufactured-reality attacks rather than passive mailbox monitoring. It traces the pattern through real exploited Zimbra CVEs in CISA's KEV catalog (CVE-2024-45519 postjournal command injection, CVE-2025-27915 stored XSS via calendar invite used against Brazilian military targets, CVE-2026-73570 SNMP command injection) and earlier 2022 to 2023 zero-days (CVE-2022-27925, CVE-2022-37042 path traversal plus auth bypass, CVE-2023-37580) exploited by multiple threat groups per Google's Threat Analysis Group.

StepSecurity documents a supply-chain attack against @memtensor/memos-cloud-openclaw-plugin on npm (versions 0.1.21, 0.1.23, 0.1.25) and MemoryOS 2.0.34 on PyPI, which insert a hidden "sckit" launcher into normal plugin/import lifecycle code (no install scripts) to spawn a platform-specific Go binary that harvests the parent process's environment and the user's AI prompt text. The Go payloads contain regex patterns for AWS, GitHub, GitLab, npm, PyPI, Hugging Face, Vault, Slack, Stripe and SendGrid credentials, target the user's home directory as an inventory root, and beacon to skyleen.fr "front" domains; the PyPI variant additionally hides a conditional build-backend/CI bridge that can steal PYPI_API_TOKEN during publishing and pull a hash-pinned, Ed25519-signed secondary payload via GitHub Actions. The writeup includes full IOC/remediation guidance.

A Flashbots researcher reviews the EarlyAttestationBleed paper (Muhammad Usama Sardar and Songbo Bu), which uses ProVerif formal analysis to uncover three attestation-verification bugs in confidential-computing deployments: Cocos AI's TDX verifier fails to actually compare the REPORT_DATA value despite computing it correctly, Cocos AI's SEV-SNP validator skips the comparison entirely when an empty expected-input value is passed, and Edgeless Systems' Contrast workload-policy logic can be tricked into accepting container images from untrusted host-controlled storage due to a rebase mistake. All three were implementation bugs (not protocol design flaws) and have since been fixed; the post also summarizes the paper's broader concerns about "early attestation" — exposing hardware details pre-authentication, lack of post-handshake re-attestation for long-lived sessions, and handshake-timeout tradeoffs from added attestation latency.

Tenet Threat Labs red-teamed a GPT-4o agent with all five A2AS BASIC pillars enabled and an MCP server. A tool response disguised as HTTP 206 pagination and OAuth steps ("Tool Parameter Injection via Semantic Orchestration Mimicry") led the agent to run a shell script, read credentials.txt and exfiltrate the token. It succeeded in over 80% of runs in November 2025. The authors argue for runtime enforcement based on content trust levels.

Socket details a supply-chain compromise of MemTensor's MemOS packages: npm package @memtensor/memos-cloud-openclaw-plugin (versions 0.1.21, 0.1.23, 0.1.25) and PyPI package MemoryOS (2.0.34), both published as the latest release on their registries. Each malicious release bundles a stripped, statically-linked Go binary called sckit that launches on import/plugin-load, scans $HOME for npm, PyPI, GitHub, GitLab, AWS, Vault and SSH credentials, and exfiltrates them to C2 servers under skyleen[.]fr, with the npm variant also capturing OpenClaw agent prompt text and the code additionally showing potential worm-like republish capability using stolen registry tokens.

Cisco Talos' CAIRN project documents CLOSEDQUORUM, a 64-bit Go Windows implant that replaces traditional C2 infrastructure with a panel of up to four commercial LLM providers (DeepSeek, Qwen, Mistral, Gemini) that vote on the implant's next action via plurality voting, with each model queried against a structured JSON decision schema constrained to inject/persist/steal/move actions. Once deployed it autonomously dumps LSASS credentials, steals browser passwords and crypto wallets (MetaMask, Exodus, Ethereum), and exfiltrates AES-256-GCM-encrypted data to an operator's Discord webhook, all without further human tasking. The post details the developer's apparent credentials-as-a-service distribution model, deterministic tie-breaking favoring DeepSeek, and provides SHA256 hashes plus a YARA detection rule for the family (formerly tracked as BALZAK).

Socket's research team found two beta releases of the @joyfill npm packages (@joyfill/layouts and @joyfill/components) contained an import-time JavaScript implant that resolves encrypted payloads through Tron, Aptos, and BNB Smart Chain transactions, ultimately dropping a 77KB Node.js remote-access trojan matching the DEV#POPPER family and sharing loader fingerprints with the PolinRider blockchain-loader campaign. The RAT establishes a Socket.IO C2 channel, executes arbitrary JS/shell commands, exfiltrates files and clipboard data, and persists by patching files inside VS Code, Cursor, Antigravity, Discord Desktop, GitHub Desktop, and the global npm CLI; a parallel detached-process branch fetches an additional bootstrap that can deploy a Python credential/browser-data stealer assessed as an OmniStealer variant. Because the implant fires on module load (not via npm lifecycle scripts), `--ignore-scripts` provides no protection, and the writeup includes full IOCs, blockchain addresses, C2 infrastructure, and MITRE ATT&CK mappings.

Datadog Security Research analyses two vibe-coded credential harvesting platforms, Loot and UltraVault, monitored since July 2026. Loot catalogs plaintext secrets, including 1,778 AI keys (196 live). UltraVault adds credential validation, exploit chains, a 14-bug LPE matrix and AWS key-pair correlation. The same host probed Amazon Bedrock with GetCallerIdentity, ListFoundationModels and InvokeModel, using kali-cloud Boto3 and Python-urllib user agents.

Wiz researchers reverse-engineered AWS's new sign-up experience, which silently creates a three-account AWS Organization (management, identity, and a restricted sandbox member account) with Builder ID login instead of root credentials. They found the sandbox blocks security services like GuardDuty, SecurityHub, Detective, Inspector, Macie and Access Analyzer via an allowlist SCP (FreeTierSCP), while still permitting risky practices such as IAM user access keys, public S3 buckets, and IMDSv1 EC2 instances; a data-perimeter RCP also blocks cross-account sts:AssumeRole until the account is upgraded, potentially pushing vendors back toward IAM user keys. The new IAM Role Manager feature further undermines least privilege by auto-attaching PowerUserAccess to console-created roles.

Bishop Fox reverse-engineered "MikroTrick," a two-vulnerability chain (CVE-2026-67279 and CVE-2026-86060) that lets an unauthenticated SSH client fully take over vulnerable MikroTik RouterOS 7.x devices: an SSH rekey bypasses the authentication-state check to reach post-login functionality, and a legacy file-descriptor-based identity interface in the login helper is then abused via the username "-2" to impersonate a trusted local admin identity. The post details patch diffs between RouterOS 7.23.3/7.23.4 and 6.49.20/6.49.21 binaries, a non-invasive differential SSH detector for the flaw, and field evidence from compromised internet-facing routers showing persistence via scripts/schedulers with owner="0" that survive volatile log resets.

OpenSourceMalware researchers detail WeaselBiscuit, a newly discovered lightweight JavaScript infostealer found hidden in 11+ npm packages (e.g. process-tailwind, engin1, the @biz44 scope), which shares tradecraft with DPRK-linked BeaverTail/OtterCookie but strips out wallet-draining, password decryption, and remote-shell features. The writeup walks through the full infection chain - a package auto-running a detached Node loader, fetching a Base64-encoded second stage from Npoint dead-drop URLs, and beaconing to a hardcoded HTTP C2 (103.170.217.184:8787) - plus its capabilities (Chrome extension-storage theft, clipboard capture, Windows keylogging) and a campaign-cluster graph tying packages together via shared hashes and resolver URLs. Attribution to DPRK is explicitly labeled a tentative hypothesis rather than confirmed.

VulnCheck details full exploit development for CVE-2026-20079, a CVSS 10.0 unauthenticated RCE in Cisco Secure Firewall Management Center (FMC). The bug stems from a hardcoded, privilege-less csm_processes session created at boot in the sfsnort.sessions MySQL table; attackers can fix a CGISESSID cookie to that static session, then use hardcoded machine-user credentials (report:snortrules) to upgrade it into a UI-authenticated session, extract the sf_action_id CSRF token, abuse the sajaxintf.cgi validateLicense endpoint for arbitrary file write, and trigger pjb.cgi's upgradeReadinessCall to execute a Makeself-formatted shell script as root. The post includes Perl source diffs from Auth.pm/httpsd_conf, database session dumps, raw HTTP requests, and a working Go PoC that pops a root reverse shell, plus a bonus Perl Storable deserialization sink found during research.

SpecterOps research introduces "Pass-the-Passkey," a family of 20+ attack techniques against passkey/WebAuthn authentication, including three zero-days: Windows 11 logging complete WebAuthn assertions to an Event Log readable by unprivileged users (patched July 2026), Microsoft Entra ID historically failing to enforce WebAuthn anti-replay protections (challenge reuse, session binding, signature counters), and local malware that calls the native Windows WebAuthn API directly to phish users with a convincing native-looking passkey prompt. The write-up argues these implementation failures mirror classic credential-relay attacks like Pass-the-Hash and NTLM Relay, and recommends device-bound passkeys with attestation enforcement for high-value accounts.
