🛡️ In a short video for Cybersecurity Awareness Month, ESET Chief Security Evangelist Tony Anscombe explains how unsanctioned hardware and software — commonly called shadow IT — is creating security gaps in the remote and hybrid work era. He warns that growing employee use of generative AI further increases risk by exposing sensitive corporate data outside IT control. The video outlines practical steps IT teams can take to discover, govern and mitigate these hidden risks and points to related guidance on authentication, patching and ransomware resilience.

🔒 Cyber-physical systems (CPS) underpin critical infrastructure across industry, healthcare and buildings, and their continuous availability is essential to public safety and business continuity. The article urges CISOs to prioritize CPS security, invest in OT protection, close long-standing IT–OT silos and maintain accurate asset inventories. It highlights that many organizations lack OT incident response or business continuity plans and emphasizes that rapid recovery, segmentation and tested emergency procedures are key to minimizing downtime and harm. Analysts warn of steep recovery times and severe financial and human impacts if CPS resilience is not improved.

🛡️ Cisco Talos reports a rapid rise in exploitation of public-facing applications following the mid‑July 2025 disclosure of the ToolShell chain, which targets on‑premises Microsoft SharePoint servers via CVE-2025-53770 and CVE-2025-53771. In Q3, application exploitation featured in over 60% of Talos Incident Response engagements, with ToolShell activity implicated in nearly 40% of cases. Talos urges expedited patching and network segmentation to limit lateral movement and downstream impacts such as ransomware.

🧩 Two researchers say they have solved the long-elusive fourth section of Kryptos, but reached the answer through documentary research rather than cryptanalysis, finding clues in the Sanborn papers at the Smithsonian’s Archives of American Art. The discovery comes as Jim Sanborn is preparing to auction what he describes as the solution, and the solvers report they will not publish their work. Legal threats have been made over disclosure and sale, though the legal basis is unclear. The episode raises immediate questions about provenance, transparency, and the ethics of selling a solution to a famous cryptographic artwork.

🔍 The Bitdefender 2025 Cybersecurity Assessment highlights a widening perception gap between executives and operational security teams. While 93% of surveyed cybersecurity and IT professionals report confidence in managing an expanding attack surface, just 45% of C-level leaders describe themselves as "very confident" versus 19% of mid-level managers. Without improved reporting, shared visibility and stronger cross-level communication, this divide risks underinvestment and misaligned priorities that can create critical blind spots.

🔒 Signal has moved to integrate post-quantum cryptography into its messaging stack to mitigate future quantum threats. Phase 1 uses PQXDH, a hybrid handshake combining X25519 with the KEM CRYSTALS-Kyber, to block harvest now, decrypt later attacks. Phase 2 adds SPQR, which runs alongside the Double Ratchet to form a hybrid Triple Ratchet, preserving forward secrecy and post-compromise security while handling larger key sizes, asynchrony, and message loss.

⚠️ Researchers at SquareX warn that malicious browser extensions can inject fake AI sidebars into AI-enabled browsers, including OpenAI Atlas, to steer users to attacker-controlled sites, exfiltrate data, or install backdoors. The extensions inject JavaScript to overlay a spoofed assistant and manipulate responses, enabling actions such as OAuth token harvesting or execution of reverse-shell commands. The report recommends banning unmanaged AI browsers where possible, auditing all extensions, applying strict zero-trust controls, and enforcing granular browser-native policies to block high-risk permissions and risky command execution.

🔊 A recent study by researchers at the University of California, Irvine shows that very high-resolution optical sensors in some mice can detect minute desk vibrations produced by speech. The theoretical attack, labeled Mic-E-Mouse, requires mice with extremely high DPI (≈10,000+) and very high polling rates (≈4,000 Hz+) and malware to exfiltrate raw sensor frames. The raw signals are extremely noisy, but Wiener filtering and ML-based denoising allowed partial speech recovery under controlled lab conditions. Significant practical limitations — few qualifying models, controlled setups with speakers inches from the sensor, and steep drops in accuracy with common barriers — plus straightforward mitigations make the attack largely a proof of concept for now.

⚠ Cisco Talos reports a sharp increase in attacks against public-facing applications, with the ToolShell chain exploiting unpatched Microsoft SharePoint servers rising to over 60% of IR cases this quarter. Ransomware-related incidents fell to about 20% but show evolving tactics, including leveraging legitimate tools and compromised internal accounts for persistence and phishing. Organizations are urged to prioritize rapid patching, robust network segmentation, centralized logging, MFA, and user education to reduce exposure.

🔎 GTIG describes a targeted campaign by a Vietnam-based cluster tracked as UNC6229 that uses fake job postings on legitimate platforms to socially engineer remote digital advertising workers. Victims are enticed to open password-protected attachments or visit convincing phishing portals that harvest corporate credentials and can bypass MFA. The actors abuse reputable CRM and SaaS services to increase trust, deliver remote access trojans, and ultimately take over high-value advertising and social media accounts for sale or resale.

🔒 This ThreatsDay bulletin highlights a series of recent incidents where attackers favored the easiest paths in: tricking users, abusing trusted services, and exploiting stale or misconfigured components. Notable items include a malicious npm package with a post-install backdoor, a CA$176M FINTRAC penalty for missed crypto reporting, session hijacking via MCP (CVE-2025-6515), and OAuth-based persistent backdoors. Practical defenses emphasized are rapid patching, disabling risky install hooks, auditing OAuth apps and advertisers, and hardening agent and deserialization boundaries.

🔐 Organizations are rapidly replacing embedded API keys and passwords with platform-native managed identities to reduce manual credential management and leakage risk. Enterprises report significant productivity gains—case studies cite up to a 95% reduction in time spent managing credentials and a 75% drop in time learning platform authentication. While major clouds (AWS, Azure, GCP) and CI platforms have built-in solutions, legacy systems and third-party APIs remain the primary obstacles to eliminating static secrets entirely.

🛡️ Cisco Talos Incident Response observed a surge in attacks exploiting public-facing apps in Q3 2025, driven chiefly by ToolShell chains targeting on-premises Microsoft SharePoint servers. Rapid automated scanning and unauthenticated RCE vulnerabilities led to widespread compromise, highlighting the need for immediate patching and strict network segmentation. Post-compromise phishing from valid accounts and diverse ransomware families, including Warlock and LockBit, continued to impact victims.

🚨 Unit 42 attributes a widespread smishing campaign to the Smishing Triad that uses urgent SMS messages and realistic phishing pages to impersonate toll, delivery and other critical services. Since April 2024 the operation has registered and churned over 194,000 malicious domains and 136,900 root domains, leveraging a Hong Kong registrar while primarily hosting on U.S. cloud infrastructure. The campaign appears powered by a large phishing-as-a-service ecosystem and seeks PII, credentials and payment data. Advanced URL Filtering and Advanced DNS Security provide protections; contact Unit 42 Incident Response for urgent help.

🔒 Trend Micro reports that the Vidar infostealer has been upgraded to Vidar 2.0, featuring a complete rewrite in C, multithreaded exfiltration, custom browser credential extraction and an AppBound bypass targeting Chrome's app-bound encryption. The release, announced by an actor calling themselves "Loadbaks" on October 6, follows a decline in Lumma Stealer activity after law enforcement disruption and doxxing of its developers. Researchers warn security teams to anticipate increased Vidar activity through Q4 2025 and to adapt detection and mitigation strategies accordingly.

🛡️ How a CISO handles a major incident can make or break their career. A Cytactic survey of 480 senior US cybersecurity leaders, including 165 CISOs, found that 65% said leading an incident response elevated their internal reputation while only 5% said it hurt it. Experts say a well-managed response can translate into better budgets and authority, but prevention work is often invisible and a single failure can still cost a CISO their job.

🛡️ This article summarizes six prominent IT risk-assessment frameworks—COBIT, FAIR, ISO/IEC 27001, NIST RMF, OCTAVE and TARA—and explains their core purpose and methods. It contrasts governance-oriented, standards-based, lifecycle and threat-centric approaches and highlights where quantitative analysis or certification focus applies. The overview helps security and IT leaders identify which model or combination of models best fits organizational needs.

🔒 The Microsoft Digital Defense Report 2025 warns that cyber threats are accelerating in speed, scale, and sophistication, driven by AI and coordinated, cross-border operations. Attack windows have shrunk—compromises can occur within 48 hours in cloud containers—while AI-powered phishing and credential theft have grown markedly more effective. For CISOs this requires reframing security as a business enabler, prioritizing resilience, automation, and modern identity controls such as phishing-resistant MFA. The Secure Future Initiative provides practitioner-tested patterns to operationalize these priorities.

📱 The 2025 Verizon Mobile Security Index underscores growing danger as mobile devices account for the majority of global internet traffic and increasingly serve as primary attack surfaces. Check Point highlights the rise of AI-powered threats, persistent phishing, and human error that expand exposure. Organizations must rethink security architectures, strengthen endpoint controls, and adopt AI-aware defenses across apps, devices, and identities to reduce risk.

🔒Modern guidance favors long, memorable passphrases over short, complex passwords. Length provides far more effective entropy than symbol substitution, making offline brute-force attacks exponentially harder for attackers using modern GPU rigs. Passphrases lower helpdesk resets, discourage insecure reuse, and align with NIST recommendations. Implement by raising minimum length, dropping forced complexity, and blocking compromised credentials in real time.
