The Rise of Agentic Attacks: What They Look Like, and Where They're Headed

Wiz research on intrusions where AI agents do the hands-on attacker work. It reviews public cases (ARTEX against South Korean banks and the ConnectWise compromise, Hermes at Thailand's Ministry of Finance, JPCERT/CC, CrowdStrike, DIVD) and three Wiz-investigated attacks. It distills fingerprints: machine-paced iteration, embedded natural-language reasoning, self-correcting scripts, checklist enumeration, noisy lateral movement, probe-before-payload habits and self-named scratch files. It also covers attribution, scale and defense implications.

ConnectWise (SkyKick) Vendor Credentials Abused in M365 Attacks

Huntress documents abuse of ConnectWise Cloud Backup (formerly SkyKick) vendor app credentials, used on October 15 from 144.172.64[.]128 to obtain Microsoft Graph tokens in at least 162 customer M365 tenants via client assertion. In one tenant, a ConnectWise Cloud Management Teams app self-assigned Global Administrator and added client secrets to an MSP management app and Huntress's own app, a persistence technique. The post lists application IDs, Entra sign-in and audit-log checks, user-agent indicators (kiota-dotnet vs Python-urllib/3.12, curl/7.88.1), and mitigation steps such as disabling (not deleting) the enterprise apps and reviewing added credentials.

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.

Claude reveals ECDSA curve origins

Anthropic's Frontier Red Team reports that Claude, given no hint, worked out how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They came from the C library's lrand48 LCG seeded with Unix timestamps from 1997–98, not from a hash of a phrase. Claude found this by scanning for weak-PRNG signatures and recovering the PRNG state with LLL lattice reduction. It also traced several prime-curve base points to the FreeLIP random generator. The post includes Python code that reproduces the seeds and base points. It says this is not an attack and makes backdoor claims less plausible. B-163 and the other base points remain unexplained.

CVE-2026-21589: Critical unauthenticated arbitrary file access in Atlassian products

Rapid7's analysis of CVE-2026-21589 (CVSSv4 9.3), a critical unauthenticated arbitrary file read vulnerability affecting Bitbucket, Confluence, Jira Software/Service Management, Bamboo, Crowd, Crucible, and Fisheye Data Center products. It summarizes watchTowr Labs' root-cause finding that double-colon (::) sequences can act as path separators in Atlassian's web-resource handling, enabling path traversal to read arbitrary files within the Tomcat web root — including crowd.properties credentials that can be chained to create a rogue jira-administrators account. The post provides emergency patching guidance, Atlassian's WAF/RewriteValve mitigations, log-hunting regex, and notes public Python PoC and Nuclei templates exist.

Write Like It's 1866: LLMs Relearn Telegraphese

The author revives "cablese," the terse telegraph-era writing style, as an LLM prompting technique: instructing a model to write dense, article-dropping summaries cuts output tokens 25–49% depending on model family, while downstream models (including ones never shown the instruction) answer comprehension questions from the compressed text at parity or better than from plaintext. The piece introduces the "Telegraph Test," an open benchmark (github.com/Travis42/telegraph-test) with ~1,300 questions over 50 passages and a fixed deterministic grader, used to measure compression ratio, cross-model legibility, and read-back/decode costs for GLM-5.3-Flash, Gemma, Qwen and gpt-5-mini; it also contrasts this human-readable, auditable register against emergent machine-only compression protocols described in other papers (BabelTele, GLOSSOGEN) and existing tools (Terse, Caveman).

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.

Learning Jazz Pianist Style with Cross-Attention Conditioning

An ISMIR 2026 (Abu Dhabi) research project that fine-tunes Aria, a transformer pretrained on piano MIDI, on solo recordings from twelve jazz pianists in the PiJAMA dataset, adding a gated cross-attention layer that conditions generation on a learned per-pianist embedding. Because standard held-out perplexity is nearly blind to style (the next note is predictable regardless of pianist), the authors instead measure style transfer by sliding a pianist classifier over freely generated continuations: conditioned continuations are attributed to the intended pianist 70% of the time versus 37% unconditioned, and a classifier trained only on generated music identifies real recordings with 95% accuracy. The page is an interactive demo with audio examples, blindfold listening tests, and per-pianist results (e.g. 96% attribution for Hank Jones/Dick Hyman vs 29% for Cedar Walton), alongside a link to the full paper with ablations on mismatch conditioning and memorization checks.

The cases are cache poisoning on apis.google.com (an unkeyed `extra_path` injected into cached JS), XSS on admin.google.com where the agent bypassed the `sig` check by getting the authorize endpoint to sign a `javascript:` URI, and a UXSS in the Tag Assistant extension via a weak `onConnectExternal` origin check and nonce exfiltration.

The actor took three tries to install AnyDesk (certutil and PowerShell attempts were blocked by Defender), created an 'oldadministrator' account, disabled Defender, then ran Silent XMR Miner Builder, which compiled a Monero miner on the endpoint using csc.exe, cvtres.exe, donut, tcc and MinGW gcc. The miner ran masquerading as explorer.exe against C3Pool; the post gives command lines and detection ideas such as unusual compiler child processes from an unsigned parent and explorer.exe with mining arguments.

The Closed Quorum: Inside the First Reported Autonomous AI C2 Implant

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: Two Joyfill npm Beta Releases Compromised to Deliver DEV#POPPER Remote Access Trojan

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.

Potential for Remote Code Execution in Microsoft SCCM via Newly-Discovered Exploit Chain

XM Cyber researchers detail a four-stage exploit chain in Microsoft SCCM (Configuration Manager) that lets any unprivileged domain user achieve SYSTEM-level remote code execution on the primary site server: a missing authorization check on the AdminService UploadExtensionInChunks endpoint (CVE-2026-47301), a weak code-signing check that accepts any commercial certificate, a "CabSlip" Zip-Slip-style path traversal in CAB extraction giving arbitrary file write, and DLL hijacking of adsource.dll loaded by the SYSTEM-level SMS Executive service. Microsoft patched the RBAC bypass in July 2026, but the rest of the chain remains exploitable via the built-in Operations Administrator role until a full fix in ConfigMgr 2609 (October 2026); the article also gives log-based detection guidance (AdminService.log DirectoryNotFoundException/HTTP 500 patterns) and interim mitigations.

PolinRider Caused Dozens of npm, Go, PHP Compromises

OpenSourceMalware's research ties together JFrog's, Nextron's, and Socket's separate reports on compromised html-to-gutenberg/fetch-page-assets npm packages, 16 Go modules, and Joyfill's poisoned beta releases, attributing all of them to DPRK's PolinRider campaign via shared XOR keys, TRON/Aptos wallets, C2 infrastructure, and the fa-solid-400.woff2 loader file hash. The piece argues these aren't targeted account takeovers but automated propagation from infected maintainer machines (via temp_auto_push.bat git history rewriting and stolen .npmrc tokens), and uses GH Archive to prove that 43 of 64 analyzed Go module pseudo-version timestamps were forged to appear years older than the actual malicious push. Delivered payloads include InvisibleFerret/DEV#POPPER RAT and the OmniStealer Python infostealer, and the article links a PolinRider crossover into a compromised Packagist/PHP package (roberts/leads) via shared C2 infrastructure.

Snyk VulnBench JS 1.0: Can LLMs Find the Same Bugs Twice?

Snyk's VulnBench JS 1.0 report runs 300 repeated agentic security-review scans (10 JS/Express fixtures x 6 model configs x 5 repetitions) to measure whether LLMs like Claude Opus 4.6/4.7 and Claude Sonnet 4.6 find the same vulnerabilities twice, benchmarked against deterministic Snyk Code SAST reference findings. Key results: reference-matched LLM findings were highly repeatable (84.8% appeared in all 5 runs) while extra, non-reference LLM findings were unreliable (only 14% reproduced in all runs), the best LLM config (Opus 4.6 Medium) reached only 75.4% Snyk-reference F1 with a 24.6-point gap to SAST, and higher-cost models (Opus 4.7 Max) did not outperform cheaper ones despite 5.7x cost. The study argues LLM review and SAST catch different vulnerability classes (LLMs strong on injection/SSRF-type bugs, weak on path traversal/resource-limit enumeration) and should be combined rather than substituted.

Socket: npm Package Uses Prompt Injection + Token Flooding to Evade AI Malware Scanners

Socket Threat Research analyzed shai_hulululud@1.0.48596, a ~9.28MB npm package whose index.js opens with a Japanese-language block comment simulating bioweapon-production instructions to trigger LLM safety refusals, follows with a fake 'SYSTEM OVERRIDE' prompt-injection block aimed at AI reviewers, then floods the file with tens of thousands of repeated comment lines (3.5M+ tokens) before appending doubly-obfuscated (character-substitution plus AES) JavaScript. The deobfuscated payload reintroduces the same policy-triggering content and scanner/vendor-referencing strings, and was classified as protestware rather than a functional credential stealer; the piece argues this demonstrates a practical LLM-specific denial-of-service pattern (prompt injection + safety triggers + context flooding + obfuscation) that AI-assisted supply-chain scanners must defend against via deterministic preprocessing, fail-closed behavior, and combining LLM review with static/AST/entropy/behavioral analysis.

Local administrator account remote logon in Windows

A pentest writeup explaining why remote logons with a shared local administrator account (e.g. from a gold image) fail against tools like psexec/smbexec/WinRM due to UAC's LocalAccountTokenFilterPolicy registry key, and how attackers can still succeed either by flipping that key, abusing the RID 500 Administrator account (governed by the separate FilterAdministratorToken key, which is unfiltered by default), or by using protocols not subject to UAC token filtering such as SSH and RDP. The author demonstrates the failure and bypass end-to-end using nxc (NetExec) and Impacket against a Windows 11 target from Kali Linux, and notes LAPS as an effective mitigation for RID 500 abuse.
