Summary Points CISOs are prioritizing AI security, focusing on defending against AI-enabled attacks, securing AI deployments, and managing shadow AI risks to prevent data leaks, bias, and unauthorized access. Data protection remains a top priority, with an emphasis on AI governance, policies, and employee training to mitigate risks posed by AI technologies. Identity management and verification are increasingly critical, especially with the rise of agentic AI, deepfakes, and the need for zero trust models to prevent unauthorized access and impersonation. CISOs are expanding their focus to geopolitical risks, third-party management, and cyber resilience to navigate the evolving threat landscape and…

Top Highlights Critical vulnerabilities in InputPlumber, used in SteamOS, allow unauthenticated users to inject UI inputs, cause denial-of-service, and leak sensitive information due to weak D-Bus authorization and full root privileges. Exploits include injecting keystrokes into active sessions, triggering memory exhaustion via file paths, and accessing sensitive files like /root/.bash_history, risking code execution and data compromise. Affected versions before v0.69.0 are vulnerable; Valve released SteamOS 3.7.20 with fixes, switching to proper authentication and system hardening to address these issues. SUSE recommends immediate updates to InputPlumber v0.69.0 or later, highlighting the importance of prompt patching to prevent exploitation on gaming and…

Summary Points A recent investigation identified 28 IP addresses and 85 domains hosting sophisticated underground carding marketplaces, trading stolen credit card data from $5 to $150 depending on details like credit limits. Researchers used internet-wide scanning of server banners on ports 80 and 443 to detect hosting infrastructure before it was obscured by protections like Cloudflare, revealing key server patterns and keywords such as “CVV” and “Dumps”. The infrastructure analysis highlighted offshore hosting providers, predominantly Privex, operating in jurisdictions with lax regulations, facilitating the operation of multiple malicious activities beyond carding. The stolen data is trafficked through layered methods, including…

Fast Facts The cybercrime landscape has evolved into “Pig Butchering as a Service” (PBaaS), where organized platforms like “Penguin” sell stolen data, fraud templates, and operational tools, dramatically lowering entry barriers for scammers worldwide. These platforms offer comprehensive fraud resources—including personal data, social media accounts, payment systems, and automation tools—enabling large-scale, sophisticated scams such as romance and investment fraud. Penguin operates under multiple aliases and openly advertises on encrypted platforms, providing affordable packages ranging from $50 to $2,500, which include stolen identities, digital infrastructure, and victim engagement tools. The shift to organized service ecosystems complicates enforcement, requiring efforts to target…

Exploitation of Spoofing Techniques: Phishing actors are utilizing complex email routing and misconfigured spoof protections to send deceptive emails that appear to originate from legitimate internal domains, increasing the risk of credential theft and financial scams. Rising Threat Visibility: Since May 2025, there’s been a marked increase in opportunistic phishing campaigns exploiting this method, primarily targeting various organizations using phishing-as-a-service platforms like Tycoon2FA. Prevention Strategies: Organizations not using Office 365 should implement strict DMARC, SPF, and DKIM policies, and properly configure third-party connectors to enhance email security and prevent spoofed messages. Impact and Consequences of Successful Attacks: These phishing attacks…

Fast Facts Instagram clarified that its systems were not breached; the recent password reset emails were caused by an external party exploiting a now-fixed issue to spam reset requests without compromising account access. Approximately 17.5 million accounts’ data—usernames, emails, phone numbers, and partial locations—were leaked and appeared on dark web markets, raising fears of targeted attacks. The platform emphasized that the flaw only allowed triggering password reset emails and did not enable password changes or account logins. Experts recommend users enable two-factor authentication, use unique passwords, and stay vigilant against phishing, especially given the exposure of contact data linked to…
