1. Executive Summary
The pipeline processed 112 reports across 14 named sources in the last 24 hours, with 9 rated critical and 60 high. The dominant theme is software supply chain risk: a Mini Shai-Hulud variant named Miasma compromised at least 32 packages under the @redhat-cloud-services npm namespace, prompting Red Hat to purge the packages and Unit 42 to publish a refreshed npm threat landscape report. Google released June Android patches addressing CVE-2025-48595, an Android Framework privilege-escalation flaw under limited targeted exploitation. CISA added CVE-2024-21182 (Oracle WebLogic Server T3/IIOP unauthenticated RCE) to the KEV catalogue with a 4 June federal remediation deadline. Microsoft pushed eight additional critical CVEs spanning GnuTLS, PHP-FPM, CoreDNS (TSIG auth bypass over DoH/DoH3/gRPC/QUIC) and the golang.org/x/crypto/ssh package (two auth-bypass class issues). Ransomware leak-site activity remains elevated, with Qilin, Safepay, Krybit, Nova and Coinbase Cartel posting victims across manufacturing, healthcare and construction.

3. Priority Intelligence Items
3.1 Mini Shai-Hulud “Miasma” Variant Compromises Red Hat Cloud Services npm Packages
Source: Unit 42, Recorded Future News
A compromised GitHub account was used on 1 June to push a credential-stealing payload into 32 packages under the @redhat-cloud-services npm namespace, which collectively receive ~117,000 weekly downloads. The payload, named Miasma by its authors, is a cosmetic re-skin of the Mini Shai-Hulud worm whose source TeamPCP published on 12 May along with a $1,000 BreachForums “largest supply chain attack” contest. Red Hat removed the packages and states no customer action is required based on preliminary analysis. Unit 42’s parallel write-up confirms Mini Shai-Hulud is “no longer scoped to TeamPCP” — copycat activity using the leaked source is muddying attribution. Recent activity in this cluster includes the March LiteLLM compromise (which led to a Mercor breach) and a separate axios JavaScript library campaign attributed to North Korean operators.
Affected: npm @redhat-cloud-services/* packages; downstream CI/CD pipelines that consumed those packages between commit time and Red Hat’s pull. Sector: software development, cloud services.
MITRE ATT&CK: T1195.002 (Supply Chain Compromise: Software Dependencies), T1566.001 (Spearphishing Attachment — earlier Shai-Hulud waves), T1071 (Application Layer Protocol), T1197.001 (File Deletion).
SOC Action: Query SCA/SBOM inventories for any
@redhat-cloud-services/*package installed on or after 2026-06-01. Rotate npm tokens, GitHub PATs and any cloud credentials referenced in build environments that pulled affected versions. Add detections for outbound connections from build agents to non-Red-Hat endpoints duringnpm installwindows. Blockpostinstallscripts on developer workstations where business-justifiable.
3.2 Google Patches Actively Exploited Android Framework Zero-Day CVE-2025-48595
Source: BleepingComputer
Google’s June Android Security Bulletin addresses 124 vulnerabilities, including CVE-2025-48595, an Android Framework flaw under “limited, targeted exploitation”. The flaw allows local code execution and privilege escalation on Android 14+ devices without user interaction. Google has not released technical details; historically, similar Framework zero-days have been weaponised by commercial spyware vendors and nation-state operators against journalists, dissidents and government targets. Two patch levels were issued: 2026-06-01 and 2026-06-05 (the latter bundling Qualcomm and kernel fixes). Pixel devices receive updates immediately; OEM rollouts will lag.
Affected: Android 14, 15, and 16 devices across all OEMs.
MITRE ATT&CK: T1068 (Exploitation for Privilege Escalation), T1404 (Exploitation for Client Execution).
SOC Action: Enforce mobile SPL ≥ 2026-06-05 via MDM. Flag managed Android devices stuck below the 2026-06-01 SPL for forced compliance within 7 days. For executive-protection populations, audit sideloaded apps and review recent SafetyNet/Play Integrity attestation failures.
3.3 CISA Adds Oracle WebLogic CVE-2024-21182 to KEV — Federal Deadline 4 June
Source: BleepingComputer
CISA added CVE-2024-21182 to the Known Exploited Vulnerabilities catalogue and issued a BOD 22-01 directive requiring federal agencies to patch by midnight 4 June 2026. The flaw, patched by Oracle in July 2024, allows an unauthenticated remote attacker with network access via T3 or IIOP to take complete control of Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0. Shodan currently identifies 1,592 internet-exposed vulnerable instances (961 on 12.2.1.4.0; 631 on 14.1.1.0.0). CISA explicitly urged private-sector defenders to apply the same urgency.
Affected: Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0 with T3/IIOP exposed.
MITRE ATT&CK: T1190 (Exploit Public-Facing Application), T1021 (Remote Services), T1071.001 (Web Protocols).
SOC Action: Inventory WebLogic deployments; block T3 and IIOP at the perimeter where not business-essential. Hunt outbound traffic from WebLogic JVMs spawning
java-child processes such ascmd.exe,powershell.exe,wscript.exe, or reverse-shell tooling. Verify the July 2024 Oracle CPU is applied.
3.4 Critical Library CVE Cluster: GnuTLS, PHP-FPM, CoreDNS, golang.org/x/crypto/ssh
Source: Microsoft MSRC update guide — CVE-2026-42015 GnuTLS, CVE-2026-35579 CoreDNS, CVE-2026-46595 x/crypto/ssh
Microsoft published eight critical-severity advisories on 2 June covering widely deployed open-source libraries:
- CVE-2026-42015 — GnuTLS off-by-one in PKCS#12 bag handling; memory corruption with potential RCE on systems parsing attacker-supplied PKCS#12 (TLS clients, mail systems, certificate pipelines).
- CVE-2026-35579 — CoreDNS TSIG authentication bypass on gRPC, QUIC, DoH and DoH3 transports. Unauthorised zone-transfer / DNS record access where CoreDNS exposes those transports.
- CVE-2026-46595 —
golang.org/x/crypto/sshVerifiedPublicKeyCallbackskips permissions enforcement, enabling authentication bypass in Go SSH servers using public-key auth. - CVE-2026-42508 —
golang.org/x/crypto/ssh/knownhostsfails to enforce@revokedstatus — revoked keys remain trusted. - CVE-2026-25680 —
golang.org/x/net/htmlDoS via malformed HTML parsing. - CVE-2026-6735 — XSS within PHP-FPM status endpoint.
- CVE-2025-14179 — pdo_firebird SQL injection via NUL bytes in quoted strings.
- CVE-2026-7261 — SoapServer session-persisted object use-after-free via SOAP header fault (rated high; same cluster).
No in-the-wild exploitation is reported for any of these advisories.
MITRE ATT&CK: T1190 (Public-Facing Application), T1078 (Valid Accounts — via SSH auth bypass), T1499 (Endpoint DoS).
SOC Action: Sweep SCA reports for affected Go module versions (
golang.org/x/crypto,golang.org/x/net), GnuTLS, CoreDNS and PHP-FPM. Prioritise: (a) Go SSH bastions or jump-hosts that authenticate viaVerifiedPublicKeyCallback; (b) CoreDNS instances exposing gRPC/QUIC/DoH/DoH3 transports (common in service-mesh and resolver deployments); (c) certificate ingestion pipelines that parse PKCS#12 with GnuTLS. Rebuild and redeploy.
3.5 Gamaredon × Turla — Confirmed Joint Operations Against Ukraine
Source: SentinelOne LABScon
ESET researchers Matthieu Faou and Zoltán Rusnák presented LABScon evidence that Gamaredon tooling (PteroGraphin, PteroOdd) was used between February and June 2025 to deploy Turla’s Kazuar backdoor on Ukrainian military and government targets — and in at least one instance to restore Turla’s access after the group lost its foothold. This is the first technical confirmation of operational hand-off between the two Russian state-aligned actors, suggesting an access-broker / advanced-implant division of labour. The talk also examines Kazuar v2 and v3 capabilities. Correlated with separate FSB Gamaredon coverage (GammaPhish/GammaWorm) in the same batch.
Affected: Ukrainian government, military, defence-industrial base.
MITRE ATT&CK: T1566 (Phishing — Gamaredon spearphishing), T1071.001 (Web Protocols), T1027 (Obfuscated Files), T1082 (System Information Discovery).
SOC Action: For organisations supporting Ukraine operations, hunt for PteroGraphin / PteroOdd loader artefacts (LNK + HTA /
mshta.exelineage from user%TEMP%), Kazuar C2 patterns, and persistence via scheduled tasks or registry Run keys with random-named values. Block macro execution from external sources; alert onmshta.exespawned byoutlook.exeorexplorer.exe.
3.6 Meta AI Abused to Hijack High-Value Instagram Accounts
Source: BleepingComputer
Multiple Instagram users — including accounts previously used by the Obama White House team, researcher Jane Manchun Wong, @hey, and @korn — reported takeovers in which attackers convinced Meta’s AI-powered support to change the account email. Attackers pulled the target’s profile photo, animated it via an AI video generator, and submitted the resulting “selfie video” to Meta’s identity-verification flow, which accepted the synthetic media and bypassed 2FA. VPN endpoints in the target’s home region were used to pass geolocation checks. Recovery is hampered by Meta’s removal of human support pathways. Meta VP Andy Stone said the “issue has been resolved” for affected accounts; the underlying control gap (AI accepting deepfaked selfie video) is not publicly resolved.
Affected: Instagram users; broader risk to any platform that gates account recovery on AI-evaluated liveness/selfie checks.
MITRE ATT&CK: T1566 (Phishing — social engineering), T1078 (Valid Accounts), T1133 (External Remote Services).
SOC Action: Brief executive-protection clients about the attack pattern. For corporate-managed social accounts, enable hardware-key 2FA where available, lock email-change actions behind admin approval, and pre-stage break-glass contacts via Meta Business support tier. Treat platform account-recovery flows that rely solely on AI verification as compromised by design.
3.7 Operation FlutterBridge — macOS Malvertising Drops FlutterShell Backdoor
Source: Unit 42
Unit 42 tracks an expanding macOS malvertising campaign (cluster CL-CRI-1089, a successor to JSCoreRunner) distributing FlutterShell, a Flutter-framework backdoor with shell-execution, filesystem manipulation, and AI-summarisation abuse for data exfiltration (documents routed through an attacker-controlled summariser before processing). Distribution is via hundreds of Google-verified ads using shell-company advertisers; targeting emphasises Anglophone and Western European markets. Google has suspended the advertiser accounts. CL-CRI-1089 also runs Windows operations (RecipeLister, Calendaromatic — previously bucketed under “TamperedChef”).
Affected: macOS desktops in Anglophone / Western European user populations.
MITRE ATT&CK: T1566.002 (Spearphishing Link — via search-ad), T1071.001 (Web Protocols), T1059 (Command & Scripting Interpreter), T1567 (Exfiltration Over Web Service).
SOC Action: Hunt macOS endpoints for unsigned Flutter-built applications in
~/Applicationsand/Applications, processes spawningosascriptorshfromContents/MacOS/, and outbound connections from such processes to recently-registered domains. Block ad-network click-through downloads in browser policy. Add an EDR rule for AI-summarisation API calls originating from non-browser binaries.

7. Consolidated Recommendations
- 🔴 IMMEDIATE: Sweep CI/CD and developer machines for
@redhat-cloud-services/*npm packages installed on or after 2026-06-01; rotate npm tokens, GitHub PATs and cloud secrets in any environment where those packages were resolved (§3.1). - 🔴 IMMEDIATE: Apply June Android SPL ≥ 2026-06-05 to managed mobile fleet; force compliance for executive and high-risk populations within 7 days (§3.2).
- 🔴 IMMEDIATE: Patch or isolate Oracle WebLogic 12.2.1.4.0 / 14.1.1.0.0 instances; block T3 and IIOP at the perimeter ahead of CISA’s 4 June federal deadline (§3.3).
- 🟠 SHORT-TERM: Rebuild any service exposing CoreDNS over gRPC/QUIC/DoH/DoH3 (CVE-2026-35579) or running Go SSH servers using
golang.org/x/crypto/ssh(CVE-2026-46595, CVE-2026-42508); patch GnuTLS (CVE-2026-42015) wherever PKCS#12 is parsed (§3.4). - 🟠 SHORT-TERM: Deploy hunting for PteroGraphin/PteroOdd → Kazuar chains on systems supporting Ukrainian government/defence partners (§3.5).
- 🟡 AWARENESS: Brief executive-protection clients on AI-deepfake-driven Instagram account takeover; review account-recovery posture for corporate-managed social presences (§3.6).
- 🟢 STRATEGIC: Treat
npm installas a privileged operation; track Mini Shai-Hulud derivatives. Expect sustained increase in supply-chain attacks given the open-sourced Mini Shai-Hulud code and active $1,000 BreachForums contest.
