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.

Six months of honeypot data finds that 19% of traffic to sensors were malicious exploit attempts, and 95% of those attempts came from just three botnets.
The "TeamsPhisher" cyberattack tool gives pentesters — and adversaries — a way to deliver malicious files directly to a Teams user from an external account, or tenant.
Some 340,000 FortiGate SSL VPN appliances remain exposed to the threat more than three weeks after Fortinet released firmware updates to address the issue.
