From the Desk of Melissa Irace, CISO
Attackers are targeting internet-facing platforms, remote access systems, collaboration tools, and critical infrastructure. Rapid patching, strong identity controls, and operational resilience are more important than ever.
Identity systems, administrative tools, network infrastructure, development pipelines, and operational technology are becoming pathways to business disruption. The priority for leaders is therefore broader than preventing compromise. Organizations need to know whether their defenses work, whether they can contain an attack quickly, and whether critical operations can continue when technology is disrupted.
This week’s threats
01 · Severe
PaperCut NG/MF zero-day under active exploitation
PaperCut confirmed active exploitation of a zero-day vulnerability affecting PaperCut NG and MF print-management platforms. These systems often integrate with AD, authentication, email infrastructure, and business applications, making them a valuable entry point for attackers.

Our approach
We don’t simply report threats. We help organizations understand their business impact, validate their defenses, and build resilience before an incident occurs. Our intelligence-driven approach turns emerging cyber threats into practical, prioritized actions that strengthen security, improve operational resilience, and support informed executive decision-making.
Five actions to take this week
- Patch fast. Prioritize patching actively exploited vulnerabilities.
- Verify defenses. Validate identity, endpoints, and network defenses through testing and monitoring.
- Prepare and practice. Test incident response plans and conduct tabletop exercises with key stakeholders.
- Manage risk. Assess third-party, supply chain, and OT/ICS risks.
- Build resilience. Strengthen business continuity and disaster recovery.
