Place useful parts of the surrounding repos into sica-fondt by layer, per the
body model (Ada = membrane; brain/endocrine/capabilities/knowledge non-Ada):
- brain/ LLM reasoning + providers (dapr, hermes, MoMoA)
- capabilities/ REPRAG sidecars: hermes tools/skills, dapr tools, parallel
dispatch, A51 channels, and the OSINT cluster
- knowledge/ LORAG corpus: 754 cyber-skills, agency personas, secure-coding,
MITRE ATT&CK data
- reference/ defensive threat-reference (C3, shhbruh doc) + AdaYaml parser
License handling: AGPL sources (worldosint, advanced_evolution, mercury,
Reticulum) and GPL DeTTECT are SPEC-only clean-room/port descriptions — no
copyleft code copied. MIT/Apache/data parts copied as working trees.
Safety: shhbruh escape/persistence material and C3 covert-C2 kept as reference
only, not wired into the running organism. See CONSOLIDATION.md.

|
## Relevant Event IDs
|
|
|
|
| Event ID | Source | Description |
|
|
|----------|--------|-------------|
|
|
| 1 | Sysmon | Process Create — captures schtasks.exe with full command line |
|
|
| 11 | Sysmon | File Create — task XML written to System32\Tasks |
|
|
| 12/13 | Sysmon | Registry Create/Set — task registry modifications |
|
|
| 4698 | Security | Scheduled task registered (includes task XML content) |
|
|
| 4702 | Security | Scheduled task updated |
|
|
| 4699 | Security | Scheduled task deleted |
|
|
|
|
## schtasks.exe Suspicious Flags
|
|
|
|
| Flag | Description | Detection Value |
|
|
|------|-------------|----------------|
|
|
| `/create` | Create new task | Baseline detection |
|
|
| `/s <host>` | Remote system target | Lateral movement indicator |
|
|
| `/ru SYSTEM` | Run as SYSTEM | Privilege escalation |
|
|
| `/sc onstart` | Run at system boot | Persistence |
|
|
| `/tr "powershell -enc"` | Encoded PowerShell payload | Obfuscation |
|
|
| `/tn \Microsoft\Windows\*` | Masquerade as Microsoft task | Evasion |
|
|
|
|
## Splunk Detection Queries
|
|
|
|
```spl
|
|
index=sysmon EventCode=1 Image="*\\schtasks.exe" CommandLine="*/create*"
|
|
| eval suspicious=if(match(CommandLine,"(?i)(\\\\users\\\\public|\\\\temp\\\\|\\-enc)"),"YES","NO")
|
|
| where suspicious="YES"
|
|
```
|
|
|
|
```spl
|
|
index=wineventlog EventCode=4698
|
|
| spath input=TaskContent
|
|
| search Command="*powershell*" OR Command="*cmd.exe*"
|
|
```
|
|
|
|
## Sysmon Configuration (Task Monitoring)
|
|
|
|
```xml
|
|
<RuleGroup groupRelation="or">
|
|
<ProcessCreate onmatch="include">
|
|
<Image condition="end with">schtasks.exe</Image>
|
|
<Image condition="end with">at.exe</Image>
|
|
</ProcessCreate>
|
|
<FileCreate onmatch="include">
|
|
<TargetFilename condition="contains">\Windows\System32\Tasks\</TargetFilename>
|
|
</FileCreate>
|
|
</RuleGroup>
|
|
```

## MITRE ATT&CK
|
|
|
|
| Technique | ID | Description |
|
|
|-----------|----|-------------|
|
|
| Scheduled Task/Job | T1053.005 | Create/modify scheduled tasks for persistence |
|
|
| Lateral Movement | T1021 | Remote task creation via schtasks /s |
