Samirbous 932bcb2ea4 [New] Suspicious SUID Binary Execution (Auditd Sequence) (#6104)
* [New] Suspicious SUID Binary Execution (Auditd Sequence)

using EQL sequence, convert this existing rule https://github.com/elastic/detection-rules/blob/ebe2a089b8806989e77531adde70314958851648/rules/linux/privilege_escalation_suspicious_suid_binary_execution.toml#L24 (compatible with Elastic Defend only).

- Auditd process event lacks process.args_count and process.parent.args_count
- auditd process events lacks process.command_line (only process.arg)

Dropped severity to medium reflect FPs that may come from those event limitations. but the rule logc matches on same LPe exploit instances:
