description: Windows Test Authoring and Execution Framework (TAEF) framework allows
|
|
you to run automation by executing tests files written on different languages
|
|
(C, C#, Microsoft COM Scripting interfaces). Adversaries may execute malicious
|
|
code (such as WSC file with VBScript, dll and so on) directly by running te.exe
|
|
detection:
|
|
SELECTION_1:
|
|
EventID: 1
|
|
SELECTION_2:
|
|
Image: '*\te.exe'
|
|
SELECTION_3:
|
|
ParentImage: '*\te.exe'
|
|
SELECTION_4:
|
|
OriginalFileName: \te.exe
|
|
condition: (SELECTION_1 and (SELECTION_2 or SELECTION_3 or SELECTION_4))
|
|
falsepositives:
|
|
