Summary Points One in three emails in 2026 are malicious or spam, with nearly half involving phishing, and 34% of organizations face monthly account takeovers. AI-driven social engineering and phishing-as-a-service platforms have democratized high-precision, high-volume credential phishing, transforming attack economics. Threat actors are shifting from file-based payloads to URLs and QR codes, exploiting blind spots like unscanned trusted formats and bypassing traditional security filters. Account takeover significantly amplifies risks, turning email defense into an identity verification challenge, which current security architectures often fail to address effectively. The Growing Surge of AI-Driven Phishing and Its Practical Impact This year’s report highlights…

Summary Points A critical vulnerability in the Funnel Builder WordPress plugin (all versions before 3.15.0.3) is being exploited to inject malicious JavaScript, mainly to steal payment data from WooCommerce checkouts. Attackers inject fake Google Tag Manager scripts that load remote payloads, including payment skimmers, by exploiting an exposed checkout endpoint without permissions checks. The flaw allows unauthorized requests to manipulate global settings and insert malicious code into every checkout page, leading to data theft such as credit card info and personal details. Users are urged to update to the latest plugin version, review External Scripts settings, and remain cautious of…

Summary Points Many organizations rely on outdated mobile management platforms primarily designed for device admin, leaving mobile threat detection gaps. Arctic Wolf’s Aurora Mobile Threat Defense provides real-time evaluation of mobile device activity, application behavior, and network connections to identify suspicious behavior. Mobile visibility remains fragmented, with traditional platforms limited to provisioning, not threat detection, prompting the need for specialized solutions like Aurora. Privacy-preserving approaches and mobile infrastructure integration are becoming central in security strategies as mobile devices increasingly serve as core enterprise access points. Enhancing Mobile Security with AI-Powered Technology As mobile devices become central to daily business activities,…

Top Highlights The rush to implement AI coding tools has increased code quality but also heightens security risks due to implementation flaws and misconfigurations. Attackers leverage AI agents like Mythos and Maven to systematically map ecosystems and exploit obscure vulnerabilities at scale. Security teams face an overwhelming influx of vulnerability reports, necessitating prioritization based on actual business impact rather than asset prestige. Focusing on root causes, standardizing vulnerability patterns, and integrating risk intelligence into development can reduce friction and improve security outcomes. The Rise of Dangerous Automation in Coding Recently, the tech world has seen a shift. Developers are now…

Fast Facts A new Linux persistence method leverages Vim plugins to automatically execute malicious payloads in ongoing sessions, facilitating stealthy long-term access. The exploitation of path traversal in Marvell QConvergeConsole (CVE-2025-6793) allows attackers to read arbitrary files without authentication. Privileged attackers can conduct authenticated PHP code injections in Dolibarr ERP/CRM by bypassing filters with uppercase tags, enabling remote command execution. Threat, Attack Techniques, and Targets The recent Metasploit update highlights multiple exploitation techniques. Notably, a new module exploits a path traversal vulnerability (CVE-2025-6793) in Marvell QConvergeConsole versions 5.5.0.85 and earlier. This attack allows an attacker to read arbitrary files without…
