Kapeka Backdoor Persistence Activity

Detects Kapeka backdoor persistence activity. Depending on the process privileges, the Kapeka dropper then sets persistence for the backdoor either as a scheduled task (if admin or SYSTEM) or autorun registry (if not). For the scheduled task, it creates a scheduled task called "Sens Api" via schtasks command, which is set to run upon system startup as SYSTEM. To establish persistence through the autorun utility, it adds an autorun entry called "Sens Api" under HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run via the "reg add" command. Both persistence mechanisms are set to launch the binary by calling rundll32 and passing the backdoor's first export ordinal (#1) without any additional argument.

Potential Exploitation of RCE Vulnerability CVE-2025-33053 - Process Access

Detects potential exploitation of remote code execution vulnerability CVE-2025-33053 by looking for process access that involves legitimate Windows executables (iediagcmd.exe, CustomShellHost.exe) accessing suspicious executables hosted on WebDAV shares. This indicates an attacker may be exploiting Process.Start() search order manipulation to execute malicious code from attacker-controlled WebDAV servers instead of legitimate system binaries. The vulnerability allows unauthorized code execution through external control of file names or paths via WebDAV.
