DPRK Hackers Adopt EtherHiding to Conceal Malware Campaigns

🔒 Google Threat Intelligence Group (GTIG) reports that a DPRK-aligned threat actor tracked as UNC5342 has employed EtherHiding since February to host and deliver malware via smart contracts on Ethereum and the BNB Smart Chain. Campaigns begin with fake technical interviews that trick developers into running a JavaScript downloader named JADESNOW, which fetches a JavaScript build of InvisibleFerret for in-memory espionage and credential theft. The method offers anonymity, takedown resistance, and low-cost, stealthy payload updates.

Siemens TeleControl Server Basic: Remote Auth Bypass

🔒 Siemens TeleControl Server Basic V3.1 contains a critical missing-authentication vulnerability (CVE-2025-40765) that allows unauthenticated remote attackers to obtain user password hashes and perform authenticated database operations. The issue carries a CVSS v3.1 score of 9.8 and a CVSS v4 score of 9.3, with network attack vector and low attack complexity. Siemens advises updating to V3.1.2.3 or later and restricting access to port 8000; CISA emphasizes isolating control networks and minimizing internet exposure. Tenable reported the issue and, to date, CISA has not received reports of public exploitation.

Quantum Readiness: Why Incident Response Won't Work

🔐 The arrival of cryptographically relevant quantum computers will create a "silent boom" where adversaries can capture encrypted traffic today and decrypt it later, making intrusions neither observed nor observable. This undermines traditional incident response and shifts responsibility to engineering teams, not a vendor checkbox. Organizations must pursue quantum readiness by engaging developers to inventory algorithms and data, assess internet-facing assets for PQC support, and build testing capability for new ciphers within their release cycles.

Jewelbug Expands Operations into Russia, Symantec Finds

🔎 Symantec attributes a five‑month intrusion (Jan–May 2025) against a Russian IT service provider to a China‑linked group tracked as Jewelbug, connecting it with clusters CL‑STA‑0049/REF7707 and Earth Alux. Attackers accessed code repositories and build systems and exfiltrated data to Yandex Cloud, creating supply‑chain concerns. The campaign used a renamed cdb.exe to run shellcode, bypass allowlisting, dump credentials, establish persistence, and clear event logs. Symantec also ties Jewelbug to recent intrusions in South America, South Asia, and Taiwan that leverage cloud services, DLL side‑loading, ShadowPad, BYOVD techniques, and novel OneDrive/Graph API C2.

Legacy Windows Protocols Enable Network Credential Theft

🔒 Resecurity warns that legacy Windows name-resolution protocols continue to expose organisations to credential theft when attackers share the same local network. By poisoning LLMNR and NBT-NS broadcasts using tools such as Responder, attackers can capture usernames, domain context and password hashes without exploiting a software vulnerability. Recommended mitigations include disabling these protocols via Group Policy, blocking UDP 5355, enforcing SMB signing, reducing NTLM, and monitoring for anomalous traffic.

New SonicWall SSLVPN Compromises Linked to Credentials

🔒 Huntress reports a fresh wave of compromises targeting SonicWall SSLVPN appliances in early October, affecting at least 16 organizations and more than 100 accounts. Attackers are authenticating with valid credentials rather than brute forcing, often from recurring attacker-controlled IPs. Some sessions involved internal reconnaissance and attempts against Windows administrative accounts, but Huntress says it has no evidence linking the activity to September’s MySonicWall cloud backup disclosure. It urges administrators to reset credentials, restrict remote management, review SSLVPN logs, and enable MFA.

Varonis Interceptor: Multimodal AI Email Defense Platform

🛡️ Varonis introduces Interceptor, an AI-native email security solution that combines multimodal AI—visual, linguistic, and behavioral models—to detect advanced phishing, BEC, and social engineering. It augments or replaces API-based filters with a phishing sandbox that pre-analyzes newly registered domains and URLs and a lightweight browser extension for multichannel protection. Integrated with the Varonis Data Security Platform, Interceptor aims to reduce false positives, accelerate detection of zero-hour threats, and stop breaches earlier in the attack chain.

Security Risks of Vibe Coding and LLM Developer Assistants

🛡️AI developer assistants accelerate coding but introduce significant security risks across generated code, configurations, and development tools. Studies show models now compile code far more often yet still produce many OWASP- and MITRE-class vulnerabilities, and real incidents (for example Tea, Enrichlead, and the Nx compromise) highlight practical consequences. Effective defenses include automated SAST, security-aware system prompts, human code review, strict agent access controls, and developer training.

Data Leak at SonicWall Impacts All Cloud Backup Customers

🔓On September 17, security vendor SonicWall disclosed that cybercriminals exfiltrated backup files configured for its MySonicWall cloud backup service. The company initially reported the incident affected 'less than five percent' of customers but has since updated that all Cloud Backup users who used the feature are impacted. Stolen files include encrypted credentials and configuration data, which could enable targeted attacks despite encryption. SonicWall has published an affected-device list and a detailed remediation playbook for administrators.

SonicWall: Cloud backup breach exposed all firewall configs

🔒 SonicWall confirmed that unauthorized actors accessed firewall configuration backup files stored in its cloud backup portal, impacting all customers who used the service.

The company is notifying customers, providing assessment and remediation tools, and urging users to log in and verify their devices immediately.

Token Theft Fuels SaaS Breaches — Security Teams Must Act

🔐 Token theft is now a primary vector for SaaS breaches, with stolen OAuth, API keys, and session tokens enabling attackers to bypass MFA and access integrated services. High-profile incidents from 2023 to 2025 show how a single unrotated token can compromise code, secrets, or customer data across platforms. Teams should prioritize discovery, continuous monitoring, and strict token hygiene—rotation, least-privilege scopes, approval workflows, and prompt revocation.

Phishers Exploit 1Password Watchtower to Steal Vaults

🔒 Malwarebytes has flagged a phishing campaign that impersonated 1Password’s Watchtower breach alerts, nearly tricking an employee into surrendering their vault credentials. The message used authentic branding, familiar phrasing and urgency cues, and embedded legitimate-seeming support links before redirecting victims via Mandrill to a typosquatted credential‑stealing page. By Oct. 2 multiple vendors had marked the site as phishing and Mandrill blocked the redirect, but earlier clicks may already have exposed entire vaults.

Chinese Cybercrime Group Runs Global SEO Fraud Ring

🔍 UAT-8099, a Chinese-speaking cybercrime group, has been linked to a global SEO fraud operation that targets Microsoft IIS servers to manipulate search rankings and harvest high-value data. The actor gains access via vulnerable or misconfigured file upload features, deploys web shells and privilege escalation to enable RDP, then uses Cobalt Strike and a modified BadIIS module to serve malicious content when requests mimic Googlebot. Infections have been observed across India, Thailand, Vietnam, Canada, and Brazil, affecting universities, telecoms and technology firms and focusing on mobile users.

Extortion Gang Reveals Alleged Salesforce Victims List

🔓 The Scattered Lapsus$ Hunters gang opened a public data-leak site claiming it stole Salesforce data from dozens of global companies, including Salesforce, Toyota, FedEx, Disney/Hulu, Marriott and Google. The group set an Oct. 10 deadline for ransom payments and threatened to publish or even use stolen documents in legal actions if demands are not met. Salesforce says its investigation found no indication the platform itself was compromised and attributes the incidents to past or unsubstantiated claims. Researchers link many breaches to vishing that installs malicious connected apps and to compromised OAuth tokens in Salesloft Drift, underscoring a broader SaaS supply-chain risk.

Chinese-speaking Group UAT-8099 Targets IIS Servers

🔐 Cisco Talos recently disclosed activity by a Chinese-speaking cybercrime group tracked as UAT-8099 that compromises legitimate Internet Information Services (IIS) web servers across several countries. The actors use automation, custom malware and persistence techniques to manipulate search results for profit and to exfiltrate sensitive data such as credentials and certificates. Talos notes the group maintains long-term access and actively protects compromised hosts from rival attackers. Organizations should hunt for signs of BadIIS, unauthorized web shells and anomalous RDP/VPN activity and share IOCs promptly.

Confucius Targets Pakistan with WooperStealer and Anondoor

🔒 Fortinet researchers attribute a renewed phishing campaign to Confucius, which has repeatedly targeted Pakistani government, military, and defense industry recipients using spear‑phishing and malicious documents. Attack chains observed from December 2024 through August 2025 delivered WooperStealer via DLL side‑loading using .PPSX and .LNK lures, and later introduced a Python implant, Anondoor. The group layered obfuscation and swapped tools and infrastructure to sustain credential theft, screenshot capture, file enumeration, and persistent exfiltration while evading detection.

Study Finds Major Security Flaws in Popular Free VPN Apps

🔍 Zimperium zLabs’ analysis of 800 Android and iOS free VPN apps found widespread privacy and security weaknesses, including outdated libraries, weak encryption, and misleading privacy disclosures. The report highlights concrete failures such as vulnerable OpenSSL builds (including Heartbleed-era versions), roughly 1% of apps permitting Man-in-the-Middle decryption, and about 25% of iOS apps lacking valid privacy manifests. Researchers warn excessive permission requests and private entitlements increase risk, especially in BYOD and remote-work environments, and recommend stronger security models, endpoint visibility and zero-trust approaches.

Researchers Find Physical Interposer Attacks on Intel, AMD

🔓 Researchers disclosed two physical interposer attacks—Battering RAM and Wiretrap—that bypass Trusted Execution Enclaves on Intel (SGX) and AMD (SEV‑SNP) platforms. Both attacks exploit deterministic memory encryption by inserting an interposer between CPU and DRAM to capture ciphertext in transit. Battering RAM can replay ciphertext and create memory aliases to expose plaintext and implant backdoors, while Wiretrap enables ciphertext-based key recovery. Practical mitigation today is limited to preventing physical access and strengthening supply‑chain and data‑center controls such as those in ISO/IEC 27001.

Red Hat Confirms Security Incident After GitHub Claims

🔒 An extortion group calling itself Crimson Collective claims to have exfiltrated nearly 570GB of compressed data from about 28,000 private GitHub repositories, including roughly 800 Customer Engagement Reports (CERs). Red Hat confirmed a security incident tied to its consulting business but would not validate the attackers’ specific claims, saying it has initiated remediation and sees no indication the issue affects its products or software supply chain. The group published directory listings and alleges finding authentication tokens and full database URIs that could be used to access downstream customer infrastructure.
