<p>Shell scripts or binaries invoking repeated 'sleep', 'ping', or low-level syscalls (e.g., nanosleep) in short-lived execution chains with no user or system interaction. Frequently seen in malicious cron jobs or payload stagers.</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 or nanosleep with no stdout/stderr I/O | DC0032 Process Creation |
| auditd:PROCTITLE | scripting loop invoking sleep/ping | DC0029 Script Execution |
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 |
|---|---|
CommandLineRegex | Environment-specific delay scripts may vary (sleep 300, ping -n 60, etc.). |
TimeBetweenSyscalls | Threshold for determining if delay is artificially extended. |
UserContext | Root vs. service user context alters risk profile. |
