Top Highlights 95% of CISOs feel pressured to hide or delay disclosure of security issues, risking transparency and accountability. CISOs face conflicting pressures from the board, PR, and teams, often needing to balance transparency with strategic timing. Many CISOs lack the authority and resources to effectively manage risks, with security often seen as a cost rather than a strategic priority. Integrating CISOs into broader business strategies and fostering a culture of transparency can alleviate pressures and enhance organizational resilience. Many CISOs Feel Pressured to Hide Security Issues Most Chief Information Security Officers (CISOs) operate without a dedicated seat at the…

Fast Facts Attackers can exploit a URL injection flaw in Microsoft Copilot to extract sensitive emails, calendar data, and files without user interaction, using a chain of three bugs combined into a single click attack. The exploit involves embedding malicious prompts in search queries, which are then covertly exfiltrated via Bing’s image URL fetches, bypassing security policies. Successful exploitation grants attackers access to critical information like MFA codes and confidential documents, enabling account takeover and data theft without needing user credentials. Threat, Attack Techniques, and Targets Researchers from Varonis Threat Labs identified a serious security flaw in Microsoft 365 Copilot…

Essential Insights CVSS scores alone often misrepresent real-world risk, as they lack context on asset exposure and business criticality, leading to misaligned prioritization. AI-enhanced analysis links vulnerabilities to specific assets and operational impact, revealing whether a flaw could cause revenue loss or operational downtime. Connecting technical vulnerabilities to business outcomes enables leadership to focus on threats that threaten financial stability or operational continuity, not just technical severity. Threats, Techniques, and Targets The report explains that security teams often deal with many vulnerabilities at once. They get reports full of CVSS scores that seem urgent. However, these scores do not always…

Fast Facts UNC6508 exploited externally facing REDCap servers, deploying the custom malware INFINITERED to harvest credentials and covertly exfiltrate sensitive research data over a year. They pivoted inside networks using stolen credentials, manipulating domain compliance and abusing enterprise tools to remain undetected while targeting high-value national security and medical research assets. The campaign resulted in long-term access, data theft, and email BCC-forwarding to threat actors, undermining institutional confidentiality and security across North American research organizations. Threat, Techniques, and Targets Google Threat Intelligence Group (GTIG) found a sophisticated campaign linked to UNC6508, a threat group from China. For over a year,…

Top Highlights ShinyHunters exploited CVE-2026-35273 in Oracle PeopleSoft to breach over 450,000 student records at the University of Nottingham, exposing sensitive personal data. A phishing-as-a-service network linked to China, Outsider, used Gemini for fake website creation and SMS phishing, targeting over 1.5 million URLs. Critical vulnerabilities like CVE-2026-50751 and CVE-2026-45657 are actively exploited, enabling remote code execution, bypassing authentication, and network propagation across enterprises. Threats, Attack Techniques, and Targets The report highlights several significant cyber threats from the week of June 15. One of the major attacks involved the University of Nottingham in the UK. Hackers, using the CVE-2026-35273 vulnerability,…

Fast Facts A network of 152 Chrome extensions disguises adware and potentially unwanted programs while logging user data like IPs and click patterns, misleading users with false privacy claims. The extensions manipulate traffic attribution by embedding URLs that mimic organic Google search traffic during installation and uninstallation, fabricating search origin signals. The campaign employs JavaScript techniques to simulate human search activity and can delete IndexedDB data, indicating sophisticated traffic fraud and potential privacy breaches. Threat, Attack Techniques, and Targets Cybersecurity researchers found a network of 152 Chrome extensions that act as live wallpaper add-ons. These extensions are spread across 38…

Quick Takeaways Hackers are actively exploiting CVE-2026-0257, a critical authentication bypass in PAN-OS, to gain unauthorized VPN access, with limited attacks observed since May 17, 2026. The exploitation allows attackers to bypass security controls and establish VPN connections, potentially compromising network gateways without post-access lateral movement identified so far. Indicators of compromise include specific IPs, host names, MAC addresses, and targeted client configurations, urging organizations to scrutinize GlobalProtect logs for suspicious gateway activity. The Threat, Attack Techniques, and Targets Palo Alto Networks reports active exploitation of a recent vulnerability in PAN-OS known as CVE-2026-0257. This flaw affects the GlobalProtect VPN…

Quick Takeaways Credential breaches are highly effective for attackers, especially with AI-driven impersonation and deepfake tech, necessitating advanced security measures. Legacy VPN architectures are insufficient for modern distributed environments, as they enable lateral movement post-compromise, risking extensive data breaches. Zero Trust Network Access, deployed via managed services like SonicWall Cloud Secure Edge, limits breach impact by verifying users/devices continuously and restricting resource access. For SMB legal firms, vertical-specific MSP security solutions offer essential compliance, risk mitigation, and trusted partnerships crucial for safeguarding sensitive data effectively. Legacy VPNs Can’t Keep Up with Modern Threats Many organizations still rely on traditional VPNs…

Traditional network security relying on payload inspection and IP threat feeds is increasingly ineffective against AI-driven, evasive attacks that bypass these defenses within hours. Modern adversaries rapidly rotate IP infrastructure, obfuscate communications, and exploit gaps left by outdated detection methods, leading to significant blind spots. Effective defense now requires proactive, real-time IP layer monitoring, zero-trust principles, and attribute-driven visibility to understand attacker infrastructure and prevent threats before they escalate. Organizations must shift from static, reactive defenses to a dynamic, inline security approach that continually verifies connection intent and reduces attack surface complexity. Understanding the Threat Landscape: Moving Beyond Old Defenses…
