Weekly Recap: PoC for FortiSIEM Vulnerability Unveiled; Insights from Rakuten Viber’s CISO/CTO on Messaging Threats

Weekly Cybersecurity Roundup: Key Highlights and Insights

This past week has been vibrant with significant developments in the world of cybersecurity. From new research papers shedding light on the intricacies of data leaks to interviews with leading figures in the industry, let’s dive into some of the most intriguing news stories that emerged.

Learning from Torrent Metadata

One noteworthy piece explores how security teams can leverage torrent metadata for insights. Traditionally viewed as a source of policy violations or insider risks, torrents are now being examined through an open-source intelligence lens. A research paper investigates how security teams can extract meaningful signals from publicly available torrent data, potentially turning what was once seen as a nuisance into a treasure trove of intelligence.

Rethinking Security in Project-Based Shipyards

In an insightful interview, Hans Quivooij, CISO at Damen Shipyards Group, discusses the complexities of securing Operational Technology (OT) and Industrial Control Systems (ICS) in project-heavy shipyards. The fluid nature of operations, characterized by rotating contractors and temporary systems, complicates access control and expands the threat landscape significantly. Quivooij emphasizes the importance of visibility in legacy environments and the vulnerabilities introduced by the integration of IT and OT systems.

The Balancing Act: Encryption vs. Abuse Prevention

In a compelling conversation, Liad Shnell, CISO and CTO of Rakuten Viber, sheds light on the unique challenges that messaging platforms face, especially in times of crisis. Shnell discusses how the balance between encryption for user privacy and measures to prevent abuse is crucial. With messaging apps becoming vital communication tools during emergencies, Shnell outlines Viber’s approach to cybersecurity, emphasizing the need for resilience while ensuring user protection.

Firmware Scanning Efficiency

Switching gears to the technical side, a new research paper delves into the world of firmware scanning. Security teams often find themselves running lengthy firmware scans overnight, which can lead to frustration and lost productivity. This paper examines how the EMBA firmware analysis tool operates in various environments, providing insights into optimizing scanning processes to save time and resources.

Open-Source Cybersecurity Management

As organizations increasingly seek structured systems for risk management, a new open-source platform called CISO Assistant has emerged. This governance, risk, and compliance (GRC) tool enables security teams to document risks, controls, and framework alignments comprehensively. The self-hosted community edition lets organizations maintain control over their data while leveraging a community-supported resource.

Addressing Verification in the Age of AI

Oscar Rodriguez from LinkedIn highlights an important shift in digital trust. In an interview, he discusses how LinkedIn is extending professional verification as a signal of trust across the internet landscape. With AI-driven fraud and impersonation on the rise, Rodriguez explains how LinkedIn aims to bolster online identity verification in collaboration with various platforms and partners.

Instagram Data Breach Rumors

The cybersecurity community buzzed with concerns over an alleged Instagram data breach last week. Malwarebytes reported on stolen sensitive information from millions of accounts, leading to an uptick in password reset requests. However, Instagram’s parent company, Meta, quickly denied any breach of their systems, leaving many users seeking clarity amidst conflicting reports.

The Rise of Browser-in-the-Browser Phishing

Security experts have warned about the resurgence of Browser-in-the-Browser (BitB) phishing attacks. By creating pop-up windows that mimic legitimate log-in interfaces, attackers have evolved their techniques to bypass traditional security measures. Educating users about the nuances of such scams has never been more critical in maintaining cybersecurity.

Urgent Patching of FortiSIEM Vulnerability

A severe vulnerability (CVE-2025-64155) in Fortinet’s FortiSIEM platform has come under scrutiny after the release of proof-of-concept exploit code. Organizations are urged to patch their systems immediately, as this vulnerability can permit unauthenticated remote attackers to execute malicious commands.

Eurail and Interrail Data Compromise

In troubling news, a data breach related to Eurail has revealed sensitive information on travelers. As security breaches continue to escalate, this incident underscores the importance of proactive measures in safeguarding personal data against unauthorized access.

Cisco Addresses Zero-Day Vulnerability

Cisco has rolled out security updates targeting a zero-day vulnerability (CVE-2025-20393) that has reportedly been exploited by attackers since late last year. The company’s rapid response aims to prevent further exploitation while highlighting the continuous threat landscape.

Cybersecurity Metrics for Executives

Bryan Sacks, Field CISO at Myriad360, discussed continuously evolving cybersecurity metrics in a recent video segment. He emphasized that these metrics should not only serve reporting purposes but should align with business priorities that resonate with executive leadership, thus fostering better decision-making.

New Developments in Security Products

Our exploration also shines a light on various new cybersecurity products making waves this week. Among them is PentestPad, designed to enhance the organization of penetration testing reports, and AuraInspector, an open-source tool that audits data access paths in Salesforce applications.

EU Chat Control Regulation Impacts Robotics

A thought-provoking academic study discusses the implications of the European Union’s proposed Chat Control regulation that could extend surveillance laws into the realm of robotics. This suggests a growing intersection between technology and civil liberties, raising ethical questions about the future of human-robot interactions.

This week’s roundup reflects a remarkable array of developments in the cybersecurity realm, highlighting ongoing challenges and innovations that define the landscape. As threats evolve, so do the strategies and tools needed to combat them, emphasizing continuous learning and adaptation in this dynamic field.
