<p>Adversary drops renamed binaries in uncommon directories (e.g., /tmp, /dev/shm) or uses special characters in names (e.g., trailing space, Unicode RLO). Execution or cronjob registration follows shortly after file drop.</p>

Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| auditd:SYSCALL | execve | DC0032 Process Creation |
| linux:syslog | rename | DC0061 File Modification |
| linux:osquery | file_events | DC0059 File Metadata |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
DropLocationPattern | Directories where new binaries are suspicious (e.g., /tmp) |
FilenameAnomalies | Regex for Unicode/RLO/space abuse in filenames |
ExecutionDelayWindow | Time range between file write and execution used for joining |
