Background for this topic.
An exploit is code, data, or a sequence of actions that uses a software, hardware, or configuration vulnerability to produce unintended behavior. Depending on the flaw and the attacker’s access, it may enable unauthorized code execution, privilege escalation, information disclosure, or denial of service. Exploitation can occur remotely through exposed services, web applications, or client software, or locally after an attacker gains limited access.
Exploitation matters because a vulnerability becomes an active attack path when the required conditions are reachable and exploitable. Defenders should inventory affected assets, prioritize remediation when exploitation is known or credible, apply patches or vendor mitigations, and reduce exposure through access controls, segmentation, and secure configuration. Monitoring for exploit-specific indicators—such as abnormal requests, unexpected processes, or privilege changes—supports detection; systems suspected of successful exploitation require containment and investigation for follow-on access.
During the second day of Pwn2Own Berlin 2025, competitors earned $435,000 after exploiting zero-day bugs in multiple products, including Microsoft SharePoint, VMware ESXi, Oracle VirtualBox, Red Hat Enterprise Linux, and Mozilla Firefox. [...]

On the first day of Pwn2Own Berlin 2025, security researchers were awarded $260,000 after successfully demonstrating zero-day exploits for Windows 11, Red Hat Linux, Docker Desktop, and Oracle VirtualBox. [...]
Ransomware has evolved into a deceptive, highly coordinated and dangerously sophisticated threat capable of crippling organizations of any size. Cybercriminals now exploit even legitimate IT tools to infiltrate networks and launch ransomware attacks. In a chilling example, Microsoft recently disclosed how threat actors misused its Quick Assist remote assistance tool to deploy the destructive

What do a source code editor, a smart billboard, and a web server have in common? They’ve all become launchpads for attacks—because cybercriminals are rethinking what counts as “infrastructure.” Instead of chasing high-value targets directly, threat actors are now quietly taking over the overlooked: outdated software, unpatched IoT devices, and open-source packages. It's not just clever—it’s
