In recent months, the cybersecurity landscape has witnessed significant developments that are set to change the way we approach security. A new infostealer malware known as REMUS has emerged, targeting browsers and stealing credentials. Meanwhile, Cisco has warned of an actively exploited SD-WAN flaw with max severity, and Microsoft has introduced a new capability to automatically roll back faulty Windows drivers.

REMUS, a new infostealer malware, has been making waves in the cybersecurity community. An analysis of 128 posts linked to the REMUS underground operation between February 12 and May 8, 2026, provides a rare look into how the group presents, develops, and operationalizes the malware within underground communities. The research helps map how the operation evolved over time and what priorities drove its development.

• Key capabilities: browser targeting mechanisms, credential theft functionality
• Similarities to Lumma Stealer: infrastructure, malware capabilities
• Underground operation: advertisements, update logs, feature announcements, operational discussions, customer-facing communications

Cisco has disclosed a max-severity authentication bypass vulnerability affecting its Catalyst SD-WAN Controller and Catalyst SD-WAN Manager platforms. The flaw has already been found to be exploited in the wild, with limited exploitation reported in May 2026.

• Vulnerability details: peering authentication bypass, unauthenticated remote attacker, administrative privileges
• Impact: allows attackers to bypass authentication and obtain administrative privileges
• Fix: software patch available

Autonomous systems are finally working, with Waymo recently crossing a major milestone of over 170 million autonomous miles driven without a single serious crash or injury. This development has significant implications for the security industry, which is approaching a saturation point in detection capabilities.

• Autonomous systems: outperforming humans in high-speed, high-volume environments
• Security implications: need for new approaches beyond detection
• Expert insights: "Autonomous systems are now outperforming humans in high-speed, high-volume environments. That is not because they are perfect, but because they are faster in the moments that matter." — [Expert Name]

Cybersecurity experts are reflecting on the past, present, and future of cybersecurity. Robert "RSnake" Hansen, Katie Moussouris, Rich Mogull, Richard Stiennon, and Bruce Schneier share their insights on how their favorite columns penned for Dark Reading over the past 20 years have stood the test of time.

"The security industry has focused on detection for the last decade, but we are approaching a saturation point. Despite continued progress in detection, defenders are still falling behind while attackers retain the advantage." — [Expert Name]

• What: new infostealer malware, SD-WAN vulnerability, autonomous systems milestone
• Impact: significant implications for cybersecurity landscape

As the cybersecurity landscape continues to evolve, it's clear that new approaches are needed to stay ahead of emerging threats. With innovations in autonomous systems and the rise of new malware, the security industry must adapt and innovate to protect against the next generation of threats.

• Implications: need for new approaches beyond detection, increased focus on prevention and response
• Future outlook: autonomous systems, AI-powered security, and cloud-based solutions set to play a major role in shaping the future of cybersecurity
