Cyber threats are moving faster than ever — attackers no longer wait for patches, and trusted tools are being turned into weapons. Detection after the fact is no longer enough. In today’s landscape, every system must be treated as potentially compromised, and resilience must be built into every layer.
This week’s update highlights major exploits, rising attack trends, key vulnerabilities, and practical defenses you can act on now.
⚡ Critical Threat of the Week
Windows 0-Day Exploited in Active Ransomware Campaigns
A privilege escalation vulnerability (CVE-2025-29824) in Windows’ Common Log File System was weaponized in targeted ransomware attacks. Attackers deployed a trojan named PipeMagic to steal credentials and deliver ransomware linked to the RansomEXX family. The flaw was patched during Microsoft’s April 2025 updates, but attackers had already struck before defenses were in place.
