## Execution
### T1053.002 At (Windows)
### T1053.002 AT Scheduled Task
Atomics: [T1053.002](https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1053.002/T1053.002.md)
Detect interactive process execution scheduled by AT command.

The tests for this technique overlap heavily with [T1566.001 Spearphishing Attachment](https://github.com/keyboardcrunch/SentinelOne-ATTACK-Queries/blob/a2fd4227666db3f1c5d6713ae3e3b21bf5343b79/InitialAccess.md#t1566001-spearphishing-attachment) due to similar download and macro detections, so here we're focusing on detecting Office applications launching processes. The below query will cover tests 1, 3 and 4 but test [#2](https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1204.002/T1204.002.md#atomic-test-2---ostap-payload-download) is standalone cscript execution and will be detected with other queries.
```
(SrcProcParentName In Contains ("WINWORD.EXE","EXCEL.EXE") AND SrcProcName In Contains Anycase ("cmd.exe","cscript.exe","wscript.exe","certutil.exe","powershell.exe","msbuild.exe","csc.exe")) OR IndicatorName = "SuspiciousDocument"

#### Test 1:
This test merely uses Powershell to download a maldoc, the below query will find powershell downloads using multiple cradle methods as documented here by [HarmJ0y](https://gist.github.com/HarmJ0y/bb48307ffa663256e239). The below query should only be used for hunting purposes and covers most unobfuscated powershell cradles.
