P1 · Node2Shell (CVE-2026-111497) Exploited in the Wild Against Node.js v24.22.0 x86-64; Patch 24.22.1 Verdict card
CISA added Adobe Commerce/Magento PolyShell file-upload flaw and Google Brotli Node2Shell decoder flaw to KEV on Oct 27, 2026 (due Nov 10). Sansec reports PolyShell used to breach hundreds of stores, injecting a malicious loader via a Magento CMS block that fetches and executes an attacker payload; no next-stage malware recovered. Brotli exploit attempts seen on honeypots, including public Node2Shell exploit traffic from 94.154.43[.]7. Hunt for unexpected file uploads/web shells and modified CMS blocks in Magento, and Node.js processes spawning shells or crashing after Brotli-encoded requests.
Why P1: Both KEV-listed with active exploitation; Magento stores confirmed breached and Brotli embedded in Node.js/Envoy/PAN-OS widely deployed.

P1 · Oracle PeopleSoft CVE-2026-35273 is three chained flaws; ShinyHunters exploitation wave in September
ZDI says CVE-2026-35273 in PeopleSoft PeopleTools 8.61/8.62 chains an SSRF in the Integration Gateway (PSIGW) with PSEMHUB's default trust of 127.0.0.1 in allowedhosts.properties. From there an attacker writes a web shell through a PSEMHUB log-write command, or drops a malicious XML file that Java XMLDecoder runs when the service restarts. Mandiant/GTIG attribute zero-day exploitation (May 27–June 9) and a larger September wave to ShinyHunters (UNC6240), including a WAF bypass that requests /%50SEMHUB/. Hunt for encoded PSEMHUB paths, new JSP/web files in PeopleSoft app directories, unexpected XML in PSEMHUB, and child processes spawned by the PeopleSoft service account.
Why P1: KEV-listed unauthenticated RCE in an enterprise ERP that is actively exploited, with concrete huntable web shell and WAF-bypass behaviors.

P1 · Attackers probe newly patched Oracle E-Business Suite CVE-2026-101767 (CVSS 9.8); no confirmed compromises reported AI verdict card
Threat intelligence firm Defused reports that threat actors began probing CVE-2026-101767, an unauthenticated SQL injection in the Application Object Library of Oracle E-Business Suite, patched in the October CPU. Defused observed exploratory attempts against its decoys on October 27, and SecurityWeek reports no other in-the-wild exploitation reports. Hunters should look for HTTP requests to EBS endpoints containing SQL injection patterns and patch the October CPU fix.
Why P1: Unauthenticated CVSS 9.8 internet-facing enterprise app with early probing activity and history of Oracle EBS mass exploitation.
No IoCs extracted for this story.
P2 · Compromised camera management software (CMS.exe) leads to reverse shell, WpcMon.exe DLL sideloading and C2 beaconing
Huntress observed Sept–Oct incidents where a threat actor compromised camera management software (CMS.exe, possibly linked to 3R Global/kvision.ai) as initial access. Post-compromise, rs.win32.exe was dropped in AppData\Roaming\CMS\RemoteSetup and run as a reverse shell, legitimate WpcMon.exe was dropped in AppData\Local\Microsoft\WpcMon to sideload malicious IPHLPAPI.DLL and samcli.dll, a Run key provided persistence, and beacons went to 144.172.116[.]37. Hunt for the CMS.exe -> rs.win32.exe -> WpcMon.exe chain, WpcMon.exe outside System32, and Run key values pointing to AppData.
Why P2: Concrete huntable process chain and sideloading behaviors, but niche software and unknown exploitation vector.

P2 · Tailscale 1.104.4 fixes Tailscale SSH socket-forwarding root escalation flaws (Tailworm)
Tailscale released 1.104.4 (bulletins TS-2026-014 to 017) fixing flaws reported by Cyberdione Labs as 'Tailworm', where Tailscale SSH socket forwarding ran as root and a path-swap race let a policy-permitted session reach root-only sockets (Docker socket, tailscaled local API). In lab tests this gave root shells, /etc/shadow reads and device-key theft, chaining across policy-allowed hosts; no in-the-wild exploitation is reported and PoC is not public. Hunt for unexpected Tailscale SSH sessions using Unix-socket forwarding to docker.sock or tailscaled's local API, and unexpected new devices joining the tailnet.
Why P2: Post-authorization privilege escalation in common mesh VPN SSH; patch available, no exploitation or public PoC.

P2 · Apple backports fix for exploited CoreGraphics zero-day CVE-2026-86950 to iOS 18.7.11; no public attack details
Apple released iOS and iPadOS 18.7.11 to patch CVE-2026-86950, a CoreGraphics flaw that Apple described as exploited as a zero-day in an extremely sophisticated attack, alongside 286 fixes in the 27.2 releases. The vulnerability was discovered by Meta's product security team and first patched in late September in iOS 26.7.1, iPadOS 26.7.1, macOS Tahoe 26.7.1 and macOS Sequoia 15.8.1. SecurityWeek reports there does not appear to be any public information detailing the attacks exploiting this CVE, so hunters have no published behaviors or indicators to act on yet.
Why P2: Actively exploited zero-day in widely deployed Apple OS, but sources publish no attack behaviors or detection guidance.
No IoCs extracted for this story.
P2 · CyberStrikeAI: TrendAI reports AI-driven attacks on at least 19 Japanese organizations and edge-device campaigns against Cisco, Citrix, F5 and Yamaha
TrendAI analyzed three exposed server environments used by threat actors to conduct AI-assisted intrusions, with the first case abusing the open-source CyberStrikeAI pen-testing tool to run a 44-agent pipeline across reconnaissance, exploitation, C2, persistence, exfiltration and reporting. The source says at least 19 organizations, including at least 16 in Japan, were subjected to validation activity, and one intrusion against a GIS server with default credentials led to theft of records and Windows credentials. A third case used AI only to build operator tools for campaigns against Cisco, Citrix, F5 and Yamaha edge devices, but the article gives no specific behaviors or indicators to hunt for. Hunters should review exposed-service logs and default-credential access on internet-facing GIS and edge systems.
Why P2: Concrete intrusion pattern against commonly exposed edge and web systems, but the source lacks command-level detail or indicators.
No IoCs extracted for this story.
P2 · Skyw4lker device code phishing campaign targets US manufacturing, technology and healthcare organizations
ANY.RUN describes Skyw4lker, a device code phishing campaign primarily targeting US organizations in manufacturing, technology and healthcare. Victims receive a password-protected business document that leads through a sites[.]google[.]com page into a Microsoft authentication flow where the attacker-initiated device authorization is completed, yielding Microsoft 365 tokens. The source reports the attack chain but does not confirm specific victim compromises; hunters should look for device code authentication events and Google Sites-hosted redirects to Microsoft login.
Why P2: Concrete phishing flow with huntable authentication pattern against M365, but the source is a vendor-contributed sandbox marketing piece without confirmed compromise counts.

P2 · Attackers tamper with Convertr shared analytics script to skim card data on Brazilian checkouts; initial access via CVE-2026-8467 unconfirmed
A Brazilian Magecart-style skimming group reportedly modified the Plausible analytics tracker hosted on Convertr's self-managed infrastructure, causing injected skimmer code to load on checkout pages of merchants using the platform. Sansec suspects initial access via CVE-2026-8467 against an outdated Plausible Community Edition install, but this is not confirmed; Convertr reportedly removed the skimmer and upgraded Plausible. Hunters should look for unexpected modifications to the Plausible tracker script and checkout-page scripts referencing 'checkout.convertr', and note that browser caching may keep the script active for up to 24 hours after cleanup.
Why P2: Active payment-card skimming on checkout pages with a suspected unauthenticated RCE, but initial access is unconfirmed and no detection content is published.

P2 · Yoba campaign uses fake GitHub AI-app projects and signed binaries to sideload a loader and XMRig miner
A brief item reports that the Yoba actor distributes fake GitHub projects posing as AI apps, with legitimately signed OpenAI and Anthropic binaries used to sideload a loader and an XMRig cryptominer. No source could be fetched, so these claims rest only on the brief item and are not confirmed by a primary source. Hunters should look for unexpected DLLs loaded beside signed AI-vendor binaries and XMRig-style mining process activity.
Why P2: Brief-level report of sideloading and miner deployment via fake developer projects; no primary source confirmed, so awareness-plus-hunt.
No IoCs extracted for this story.
P2 · Fake Android apps themed on fuel prices, VPNs and drone alerts distribute ZloyRAT and RedWing Stealer to Russian users
F6 researchers report cybercriminals promoting malicious Android apps, including a fake traffic/fuel map app, GosuVPN, and Drone Radar, through one website registered in early October to target Russian users. The apps deliver ZloyRAT, which can read SMS, contacts and calls and target banking and Telegram data, and a separate earlier F6 finding describes RedWing Stealer distributed via RadarTrevog. The source does not disclose download counts or confirmed financial losses, and it does not name the threat actor. Hunters should look for Android sideloaded apps with these names and permission requests for SMS, contacts and call access.
Why P2: Mobile malware with banking-app targeting and stated permission abuse, but no exploitation and limited technical detail in the source.

P2 · GMO Internet Group offers $1M bounty after refusing ~$50M extortion; unauthorized FX trades tied to Onamae Desktop Cloud breach
GMO Internet Group said attackers breached its Onamae.com Desktop Cloud service, which hosts Windows desktops used for FX trading, and it refused an extortion demand of about $50M received October 21. GMO says a third party installed malicious programs on some customers' servers and that customer information was exfiltrated, but how the attackers got in has not been confirmed. Brokers OANDA Japan and FXTF report unauthorized logins and trades using customer credentials believed leaked from the service, so hunters should look for unexpected logins to trading accounts and sessions from unfamiliar devices.
Why P2: Financial-sector relevance and unauthorized trading tied to leaked credentials, but no technical exploit or detection detail is published.

P2 · University of New Mexico Health hospital diverts ambulances after cyberattack; BYOD gang claims ransomware (unverified)
The University of New Mexico Health System suffered a cyberattack on a Monday that forced IT to contain the issue, diverted ambulances for about two hours, and suspended outpatient surgeries and appointments. The organization notified federal law enforcement and did not confirm ransomware; the BYOD gang claimed the attack and asserted 36,000 machines and stolen data, which is unverified. No technical details on attack vector or behaviors were published, so hunters have no confirmed artifacts to search for beyond general ransomware indicators.
Why P2: Confirmed disruptive incident at a healthcare provider, but no published technical detail or behaviors to hunt; ransomware status and actor claim unverified.
No IoCs extracted for this story.
P2 · Microsoft Authenticator for Android flaw (CVE-2026-80097) let permissionless apps impersonate Teams and obtain work sign-in tokens; no exploitation reported
A permissionless malicious Android app could abuse an exported AccountChooserActivity in Microsoft Authenticator, spoofing a trusted Microsoft app such as Teams to receive work account tokens, because a signature check validated only the claimed package's real signature. Microsoft fixed it in version 6.2606.4246 and says it has not been exploited, though Enclave's tests reported tokens without user interaction while Microsoft says an authentication step is required. Defenders should verify managed Android devices run 6.2606.4246 or later and look for unexpected third-party apps on devices with Authenticator.
Why P2: Concrete token-theft flaw in a widely deployed enterprise MFA app, but not exploited and no detection content published.
No IoCs extracted for this story.
P2 · EPICS Base 7.0.10 and earlier: four unauthenticated network flaws (CVE-2026-114595 to CVE-2026-114598) patched in 7.0.11; no public exploitation reported
CISA advisory covers four vulnerabilities in EPICS Base 7.0.10 and earlier, control-system software used at accelerators and fusion facilities, found by Causal Security's Cipher system. The flaws are tied to Channel Access and pvAccess handling and can be triggered without authentication over TCP 5064 or 5075; the most severe, CVE-2026-114595 (CVSS 9.8), is an integer overflow that could possibly enable RCE, but the researchers only demonstrated an out-of-bounds write and crash and did not achieve code execution. No public exploitation has been reported; defenders should update to 7.0.11 and review exposure of these ports.
Why P2: Unauthenticated network flaws in control-system software with no published exploitation or behaviors; patch-driven rather than active threat.
No IoCs extracted for this story.
P3 · Denver Health Medical Plan breach: vendor SquareML access key leaked publicly, exposing data of 238,083 members
Denver Health Medical Plan (DHMP) is notifying about 238,000 members that personal and health information may have been compromised after third-party vendor SquareML reported that an access key was inadvertently leaked on a publicly accessible website. The key was published June 27, 2025 and revoked August 18, 2026, and the sources state a read-only account could have been used to access a SquareML-maintained database. DHMP says it has no evidence member data was viewed or misused, only that it may have been; no technical attack details, attacker activity, or IoCs are published.
Why P3: Vendor credential exposure disclosure with no described adversary behavior or huntable artifacts; awareness only.
No IoCs extracted for this story.
P3 · FBI seizes Virtualine domain; bulletproof hosting provider accused of hosting criminal content and laundering Bitcoin
The DoJ announced the FBI seized the virtualine[.]net domain of bulletproof hosting provider Virtualine, with Hessen State Police, Dutch National Police, UK NCA, OverRIPE and Lumen participating. Court documents allege the provider advertised services for phishing, carding, spam and port scanning and hosted abusive content, and that customer payments in unhosted Bitcoin were laundered. The sources contain no technical intrusion details; the operator disputes the CSAM allegations, and Spamhaus reported the operator moved to AS209800 in 2025.
Why P3: Law enforcement action against a bulletproof host with no concrete huntable behaviors in the sources; awareness only.

P3 · UK police supplier breaches: watchdog says suppliers holding police data were repeatedly compromised since 2021, no details published
HMICFRS reported that hackers repeatedly compromised third-party ICT suppliers holding UK police information since 2021, citing information shared by the Police Digital Service and National Police Chiefs' Council. The report does not name suppliers, forces, attack counts, or whether data was stolen, and it contains no technical attack details. Hunters have no specific behaviors, artifacts, or indicators from this source; the actionable point is the finding that most police supplier contracts lack ongoing security assurance and that supplier system logs are often not visible to in-house teams.
Why P3: Awareness only: vague supply-chain breach claims with no technical detail, behaviors, or indicators.

P3 · DOJ indicts six over Madagascar-based fake NFT investment scam center; no technical intrusion details published
The Justice Department announced indictments of Malaysian national Chui Kok Wa and five others tied to a scam operation that moved from Cambodia to Madagascar and allegedly stole over $516,695 from 74 cryptocurrency wallets of US victims via fake NFT investment schemes. The FBI reportedly gained access to more than 3,000 devices in Madagascar, but the source describes only fraud tradecraft (dating-site lures, fake NFT websites, wallet-connection drains) rather than intrusion behavior. No host-level or network indicators are printed, so there is little for defenders to hunt beyond scam-related fraud signals.
Why P3: Awareness only: fraud operation with no published technical behaviors, IoCs, or detection guidance.

P3 · Microsoft ships out-of-band Windows updates distrusting eMudhra root certificates after weak CA key disclosure
Microsoft released out-of-band Windows updates KB5134133 (Windows 11 24H2/25H2/26H2) and KB5134125 (Windows 10 21H2/22H2) on October 26 to remove trust in eMudhra root certificates tied to eight intermediate CA private keys that were weak enough to be recovered almost instantly. The sources say the compromised keys could have allowed forging certificates for legitimate websites, but do not report any observed exploitation. Admins are advised to install the updates on disconnected systems and identify certificates that depend on the removed roots, since they may need replacement.
Why P3: Certificate trust update with no described attacker behavior or observed exploitation; awareness and patch-deployment only.

P3 · GoAhead TLS flaws let revoked client certificates pass and weaken session keys; no known exploitation as of Oct 27
EmbedThis GoAhead 6.1.1 fixes several TLS flaws in the embedded web server used in routers, printers, gateways and industrial controllers. The main issue, CVE-2026-115881 (vendor-rated 9.1), affects OpenSSL-backend builds with mutual TLS and a configured revocation list, where revoked client certificates are accepted; a second issue, CVE-2026-115884 (7.4), affects LibreSSL legacy-verifier builds with over-long certificate chains, and a Mbed TLS Diffie-Hellman length typo has no CVE. The sources report no observed exploitation as of October 27, and whether any device maker has shipped the fix is not known, so hunters should focus on identifying GoAhead builds and their TLS backend and settings rather than on attack activity.
Why P3: Vendor-advisory TLS/authentication flaws with no reported exploitation and exposure dependent on non-default build settings; awareness only.

P3 · Project Zero compares BigSleep (LLM) and Fuzzilli on V8 bugs, finding about 25% overlap in production and about 60% in an experiment
Google Project Zero compared the Fuzzilli JavaScript engine fuzzer and the BigSleep LLM-based agentic bug finder on V8 vulnerabilities from April to September 2026. In production, BigSleep and Fuzzilli reported 45 and 37 actionable vulnerabilities respectively with roughly 25% overlap, while a dedicated experiment re-discovered about 62% of historic Fuzzilli bugs with BigSleep. The post concludes the two approaches are complementary and recommends vendors run both fuzzing and agentic code analysis; it describes no attacker activity or detectable behavior.
Why P3: Research comparison of vulnerability discovery tools with no exploitation or huntable adversary behavior.

P3 · Generative AI makes fake login pages harder to spot; vendor piece urges phishing-resistant MFA
A contributed vendor article (Keeper Security, published via The Hacker News) argues generative AI makes fake login pages and AiTM phishing easier to build and personalize. It describes attackers capturing MFA codes and session cookies or tokens through proxy-style fraudulent sites, and no specific campaign, victim, or confirmed compromise is reported. Hunters may look for sign-ins from unusual locations or devices and session token reuse, and defenders are advised to adopt phishing-resistant MFA.
Why P3: Awareness-level vendor opinion piece with no concrete campaign or huntable artifacts.

P3 · Malwarebytes survey: one in ten respondents say AI was used to make explicit images of them (no technical intrusion described)
A Malwarebytes Labs article reports on a March 2026 survey of 1,500 respondents in the US, UK, Germany, Austria and Switzerland about AI and intimacy. Per the article, one in ten respondents say AI has been used to generate nude or sexually explicit imagery of them without permission, and one in ten say someone has threatened to release AI-generated explicit imagery. The source describes attitudes and survey results rather than a specific attack, malware, or intrusion, so there is no concrete huntable adversary behavior here.
Why P3: Awareness-only survey research with no concrete technical behaviors, artifacts, or detectable indicators.
