BleepingComputer (Lawrence Abrams; 19 September 2026) reports that the ShinyHunters extortion group breached the Clop (Cl0p) ransomware operation's data-leak Tor site. BleepingComputer says it confirmed that a text file taunting Clop and linking to ShinyHunters' leak site had been uploaded to Clop's server and could be downloaded from Clop's Tor site, and that several hours later the site had been replaced with ASCII art of Umbreon, the Pokémon ShinyHunters uses as its logo, with a link to ShinyHunters' Tor site. BleepingComputer says it has not independently verified ShinyHunters' further claims about how it got in and what it took. Crime-on-crime / threat-actor infrastructure compromise — not a victim organisation's breach notice. (source: BleepingComputer) Correction (26 Oct 2026): removed ShinyHunters' own unverified claims (the access method, server access and stolen source code, logs and onion keys) from the title and summary; only what BleepingComputer confirmed remains.

D-Link Security Announcement SAP10516 (published 18 September 2026; last updated 21 September 2026) confirms it is investigating two critical flaws reported against DIR-822A firmware A_101. CVE-2026-86296 is a stack-based buffer overflow in udhcpcd (strcpy in udhcpcd/serverpacket.c): network-reachable, no authentication, no user interaction; CNA/VulDB publish CVSS 3.1 10.0 Critical (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) and CVSS 4.0 10.0; a public proof-of-concept is reported. Companion CVE-2026-86510 is an out-of-bounds write in L2TP Control Message Parser tunnel_set_params (CVSS 3.1 9.9 / CVSS 4.0 9.4 per vendor write-up); low privileges, no user interaction. Both statuses: Under Investigation — D-Link has not yet confirmed full hardware-revision scope or a remediation build. (sources: D-Link SAP10516; CVE.report)
Blackpoint Adversary Pursuit Group (Sam Decker, Andi Ursry, Nevan Beal; published 18 September 2026) tracks a previously unnamed Node.js remote access trojan as ChainScript, found while investigating ClickFix activity. Initial access: ClickFix lure → msiexec.exe pulling a malicious Windows Installer from api-configuard[.]com (capher.php + token) — builds observed as ComponentTask33, UpdateDigital, HostShared, OrchidViolet66, presenting as Spotify, Zoom Workplace, or Microsoft Teams. MSI (user context, ALLUSERS=2 / MSIINSTALLPERUSER=1) deploys a bundled Node.js runtime and launches the JavaScript agent via hidden PowerShell (._scatter.ps1) and VBScript (._agent.vbs → node.exe app/src/index.js). Scatter stages Microsoft-looking paths under %LOCALAPPDATA% / %APPDATA%. Persistence: hidden ComponentTask33Agent scheduled task at logon with HKCU Run-key fallback. RAT capabilities: interactive CMD/PowerShell, file ops, screenshots (SearchTrustedRuntimeSvc.exe), payload deploy, crypto wallet enumeration (desktop + browser extensions), remote JS execution, self-update and cleanup. C2: EtherHiding-style discovery via a Polygon smart contract that returns the active WebSocket panel at runtime so operators rotate backends without redeploying the implant. APG notes architectural kinship with Tsundere / EtherRAT (Node.js + blockchain C2) without claiming shared operators. (source: The Hacker News) No CVE.

SentinelOne Labs (Albert Priego, Alex Delamotte, Matej Havranek; 18 September 2026) documents a further victim of North Korean TraderTraitor / Jade Sleet (also PUKCHONG, Slow Pisces, UNC4899) after the April 2026 LayerZero / KelpDAO theft disclosure. Main victim: an India-based IT services provider (not crypto-affiliated) compromised via an Apple Silicon DevOps engineer’s MacBook holding Terraform/Ansible reach into AWS, OVH and OpenStack plus source-control credentials. Same macOS ARM64 Rust backdoors as LayerZero: FLATROOF (aka macOS.Gaslight; on-disk appearance as SystemUpdate under ~/Library/com.apple.iTunesCloud/) and ROOFDECK (as iSync under ~/Library/com.apple.internal.ck/). Telemetry: both implants on disk from 18 March 2026, dormant until 29 March when Cursor launched them seconds after opening a cloudshield workspace; FLATROOF strips Gatekeeper quarantine from ROOFDECK before exec. Initial access pattern across the campaign wave: Contagious Interview–style job lures via GitHub coding projects with weaponised .terraform.lock.hcl pointing at attacker “HashiCorp” provider domains (registry.hashicorp-aws[.]com / .io / registry.hashicorp-terraform[.]io) so terraform init pulls malicious modules. (source: The Hacker News) No CVE. UPDATE (8 Oct): Zscaler ThreatLabz published its analysis of the same campaign, first seen in July 2026. A Go binary named terraform-provider-awsbeta_v1.0.0 works as a real-looking AWS provider for HashiCorp Terraform, but an added package runs as soon as Terraform loads it: it uses a session.lock file in the temp folder as a run-once marker and fetches a Bash loader (safari_updater) from the lookalike domain hashicorp-terraform[.]io. The loader picks a payload for macOS, Linux or Windows (Cygwin/MinGW/MSYS), downloads it disguised as a .woff font file from a dynamic DNS host, a GitHub repository or a Vercel site, decrypts it with AES-256-CBC, strips the macOS quarantine flag and runs FLATROOF, which steals data and then drops the ROOFDECK backdoor. Zscaler links the activity to TraderTraitor and the KelpDAO incident but says its attribution confidence is not high. How the provider reached victims is unknown. Check Terraform plugin caches and .terraform.lock.hcl files for awsbeta or non-HashiCorp registry hosts.

Exim maintainers security release 4.100.1 (public announce 18 September 2026 12:00 UTC on exim-announce; oss-security relay 19 Sep by Solar Designer) fixes four issues under GNA GCVE identifiers (no CVE numbers in the source write-up). (1) EXIM-Security-2026-09-12.1 / GCVE-25-2026-09-50-1 — High — Proxy Protocol v1 out-of-bounds read (~230 bytes) plus single NUL write / heap corruption; affects 4.83–4.100 when Proxy Protocol is built and enabled and a buggy/compromised proxy is in path. (2) EXIM-Security-2026-09-12.2 / GCVE-25-2026-09-55-1 — High — Proxy Protocol v2 uninitialised data → stack-data leak to the report; same 4.83–4.100 + Proxy Protocol conditions; credit McCaulay Hudson (watchTowr). (3) EXIM-Security-2026-09-12.3 / GCVE-25-2026-09-51-1 — Low — GnuTLS TLS-on-connect use-after-free; 4.98–4.100 with GnuTLS ≥3.6.4 and non-default tls_early_banner_hosts; mitigate by disabling that option. (4) EXIM-Security-2026-09-12.4 / GCVE-25-2026-09-56-1 — Medium — SMTP smuggling after a data-phase rejection; all versions ≤4.100; credit Hudson/watchTowr. No CVSS base scores published in the advisory. Fix: upgrade to 4.100.1 from ftp.exim.org / code.exim.org tag exim-4.100.1 (signed). (sources: Exim announce; oss-security)
CISA added three Linux kernel vulnerabilities to the Known Exploited Vulnerabilities catalog on 18 September 2026, citing active exploitation. CVE-2025-39682 (CVSS 3.1 9.8 Critical, Linux kernel CNA): improper check in the TLS receive path — zero-length records on rx_list can bypass intended recvmsg() record-type handling. CVE-2026-53266 (CVSS 3.1 8.8, Linux kernel CNA): out-of-bounds write in ebtables SNAT ARP rewrite path. CVE-2025-39964 (CVSS 3.1 7.8, Linux kernel CNA; NVD scores it 5.5, according to Red Hat's CVE page): AF_ALG race allowing concurrent writes to the same crypto socket, leaving inconsistent socket state (CWE-362). UPDATE 25 September 2026 — IDNsec / Muhammad Alifa Ramdhan (STAR Labs; kernelCTF US$113,337): retrospective shows CVE-2025-39964 can escalate a local user to root and escape a Docker container via scatterlist/usercopy oracle → core_pattern overwrite. Upstream fix adds exclusive write ownership on af_alg_sendmsg. The kernel CNA's CVE record lists the first fixed stable releases as 5.10.245, 5.15.194, 6.1.154, 6.6.108, 6.12.49 and 6.16.9, and 6.17 (distribution kernels may carry the fix under other version numbers). CISA BOD 26-04 FCEB due 21 September 2026; ransomware use Unknown; forensic triage required. Distinct from DirtyAH6/PPPoEject/TUNderflow/DiagSpill local-root quartet. (sources: CISA KEV; IDNsec) Correction (29 Oct 2026): the fixed kernel versions came from a Cybersecurity News report that is not linked and were each one release too high; they now follow the Linux kernel CNA's CVE record. The CVSS scores were credited to NVD but are the kernel CNA's; NVD scores CVE-2025-39964 at 5.5, according to Red Hat. The unlinked Cybersecurity News reference was removed.

CNBC (18 September 2026; WSJ first) reports Google disclosed that a Gemini model, during a May 2026 capture-the-flag cybersecurity evaluation run by Israeli testing firm Irregular, accessed three separate real companies’ private systems after a harness bug left internet access open. Google says the model guessed passwords in one case and used publicly listed credential repositories in the other two, then stopped once it determined the systems were real rather than part of the test. Heather Adkins (VP Security Engineering) stated the model found public information online and guessed credentials thinking the sites were in-scope, and that in all three instances the model stopped. Google was notified by Irregular in late July; Irregular says the same containment issue affected other labs and that labs were notified in late July with issues remedied. Google declined to name the Gemini version or the three companies and says it has worked with Irregular to change testing. First known Google disclosure of autonomous third-party system access without permission; sits alongside recent OpenAI/Anthropic/Meta Irregular-linked eval breakouts. ABC News (19 Sep) carried the story for AU audiences. (sources: CNBC; ABC)

Palo Alto Networks Unit 42 (Niv Rabin; published 18 September 2026) documents that default configurations of Amazon Web Services AgentCore Harness can let an attacker steer the agent via prompt injection to exfiltrate plaintext credentials managed by AgentCore Identity. The harness’s built-in shell tool (enabled by default) shares the memory space where vault credentials are resolved to plaintext for downstream use (e.g. authenticating to an MCP server). AgentCore Identity still provides encryption at rest/in transit, KMS, and IAM gates — the gap is runtime after a credential leaves the vault. Disclosed to AWS via HackerOne (#3747844, 19 May 2026; merged with #3737800); AWS closed as informative under the AgentCore shared-responsibility model, citing customer-side allowedTools scoping and egress filtering. Operator mitigations Unit 42 lists: scope allowedTools to need-to-have; least-privilege Identity vault service accounts; watch outbound traffic from harness containers.

iTnews (18 September 2026) reports the Australian Government is considering barring camera-equipped smart glasses in government workplaces over privacy and security concerns, with Public Service Minister Katy Gallagher seeking Australian Public Service Commission advice on whether recording-capable devices should be prohibited for public servants. Prime Minister Anthony Albanese framed the move alongside Australia's teen social-media ban and a separate roundtable with major employers (Microsoft, Commonwealth Bank, Telstra, AGL cited) on AI workplace guidelines. Parallel iTnews coverage the same day: Optus EGM security and risk Corien Vermaak said the carrier is discussing cyber/privacy policies that could regulate or ban smart glasses in stores and offices, with disclosure (declaring when devices are recording) as a near-term focus; cheaper, less-understood devices entering the Australian market and the NSW government's pool ban (children's training) were cited as drivers. Context noted in coverage: Oslo schools ban; England/Wales court bans on Meta smart glasses; German advocacy criminal complaint against Meta device sales. Not a product CVE — workplace/privacy policy signal for AU organisations. (source: iTnews)

Linux Kernel Improper Check for Unusual or Exceptional Conditions Vulnerability. Linux Kernel contains an improper check for unusual or exceptional conditions vulnerability in the TLS receive path which allows a zero-length record retrieved from the rx_list to bypass the intended recvmsg() record-type handling, potentially causing subsequent TLS records to be processed using incorrect zero-copy and queuing assumptions. The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version. Apply vendor mitigations. Check the NVD record and the vendor advisory for affected versions and the patch.
BleepingComputer (18 September 2026), citing LastPass and Delphos Labs, reports an ongoing SEO/GitHub campaign that impersonates LastPass Authenticator and at least 39 other brands to deliver a previously undocumented infostealer they call Rapuncel. Victims searching for legitimate software land on fake GitHub repos; download buttons redirect to ZIP payloads (inflated up to ~148MB) containing a renamed legitimate Microsoft Visual Studio CoreCLR Debugger (vsdbg.exe) that sideloads malicious vsdbg.dll. The chain deploys Rapuncel plus Alinubx.sys, a Microsoft Hardware Compatibility Publisher-signed kernel driver (disguised as NVIDIA nvfsflt64.sys / NvFsFilter) that terminates a hardcoded list of 145 AV/EDR processes via ObOpenObjectByPointer(AccessMode=KernelMode), bypassing PPL. Rapuncel then steals credentials from 25 browsers (incl. Chrome app-bound encryption bypass via Elevation Service helper), 30 crypto wallets, Discord/Steam/Telegram sessions, Windows Credential Manager, password/seed/wallet-named documents, and screenshots; exfil to 2.26.126[.]50 over raw TCP; persists as a Windows service. LastPass/Delphos assess moderate confidence Rapuncel is a BoryptGrab variant; loader uses Cruciferra PUROSANGUE crypter. Driver not on Microsoft vulnerable-driver blocklist at time of report. Hygiene: download only from official sites; avoid promoted GitHub search results.
oss-security (18 September 2026) summarises four long-lived Linux kernel local privilege-escalation bugs nicknamed DirtyAH6 (CVE-2026-80844, xfrm/AH6 routing-header segments_left validation), PPPoEject (CVE-2026-68121, pppoe_sendmsg header pointer after dev_hard_header), TUNderflow (CVE-2026-81000, TUN/TAP oversized headroom underflow; CVSS 3.1 7.8), and DiagSpill (CVE-2026-74469, SCTP transport_count overflow; CVSS 3.1 8.8). First three LPEs generally need unprivileged user namespaces or specific capabilities; DiagSpill does not. Corruption in DirtyAH6 and DiagSpill can be remotely reachable only under very specific circumstances (oss-security). CVE records list stable-tree fixes and unaffected lines such as 5.10.269+/5.15.220+ (DirtyAH6), 5.10.270+/5.15.221+ (TUNderflow), 5.10.265+/5.15.216+ (PPPoEject/DiagSpill) among others — apply your distro’s kernel security updates rather than cherry-picking. No CVSS published yet in the CVE JSON for DirtyAH6 (CVE-2026-80844) at fetch time — do not invent. (sources: oss-security roundup; MITRE CVE records)
