MITRE ATT&CK

Techniques & procedures

2 distinct techniques documented for this family, organized by ATT&CK tactic.

Execution

1 technique

T1059.004Unix ShellEvidence1

The purpose of disable_functions is to enhance the security of PHP applications by preventing the execution of potentially dangerous functions that could be abused by attackers to execute malicious code... examples include exec(), system(), shell_exec(), popen(), and proc_open().

Persistence

1 technique

T1505.003Web ShellEvidence1

Searching for “popen webshell” on Google, we find a simple webshell on GitHub... A proc_open() reverse shell can be pretty simple... We placed four different webshells on a web server: proc_open.php p0wny-shell.php weevely.php popen.php
