Caddy

Attackers are exploiting unpatched TLS listeners by flooding them with incomplete ACME ALPN handshakes to exhaust server-side resources like goroutines and worker threads.

This brief details a behavioral detection strategy for identifying potential web shell deployment and persistence mechanisms by monitoring anomalous file creation activities originating from common web server processes on Linux.

This brief details how attackers exploit vulnerable web applications or deploy webshells on Linux systems to achieve persistence by executing unusual shell commands from web server processes, potentially leading to payload downloads, reverse shells, or cron-like task implants.

This brief describes how attackers exploit vulnerabilities in web applications to execute suspicious shell commands via web server processes on Linux, enabling persistence, discovery, credential access, and reverse shell establishment, which can lead to full system compromise and data exfiltration.

Identifies suspicious command executions via a web server on Linux systems, which may suggest a vulnerability and remote shell access.
