[Bug] FileInfo_7_0 error if msg has encrypted zip attachment

[nielszcert]

Describe the bug
When a msg file contains a attachment that is a encrypted it breaks.

To Reproduce
Steps to reproduce the behavior:

1. attach a zip file with a password to an email and save that email as msg
2. upload msg in TheHive
3. scan with FileInfo_7_0

Expected behavior
The application should just say that the zip is encrypted instead of crashing.

Complementary information
Traceback (most recent call last): File "/Cortex-Analyzers/analyzers/FileInfo/fileinfo_analyzer.py", line 76, in <module> FileInfoAnalyzer().run() File "/Cortex-Analyzers/analyzers/FileInfo/fileinfo_analyzer.py", line 64, in run module_results = module.analyze_file(self.filepath) File "/Cortex-Analyzers/analyzers/FileInfo/submodules/submodule_oletools.py", line 64, in analyze_file self.analyze_vba(path) File "/Cortex-Analyzers/analyzers/FileInfo/submodules/submodule_oletools.py", line 128, in analyze_vba path = decrypt(path) File "/usr/local/lib/python3.7/dist-packages/oletools/crypto.py", line 380, in decrypt exec('raise UnsupportedEncryptionError(filename) from None') File "<string>", line 1, in <module>oletools.common.errors.UnsupportedEncryptionError: Office file /tmp/cortex-job-VNuI4XYBJz5T0REiygnt-4775860985038091071/input/attachment12357675004074500511 is encrypted, not yet supported

Work environment

• Cortex Analyzer/Responder version: 7

Possible solutions
By adding a simple try: statement on line 64 of fileinfo_analyzer.py the error doesn't crash the analyzer anymore
