File upload fails and delays

[kostasthedelegate]

Hello, 

I received this mail from AMP

Hello xx xx, 

The following file you requested failed to upload:



File name: wetransfer-3f49fc.zip
Original file name: Unknown
File size: 49.8 MB
File SHA-256: eaf93b2240bc1eebda1248a294c135426eb58912a79182f09f4259c334b49805
Hostname: xx.xx.xx

Also I have several failed attempts for analysis

Any ideas why?

How could I find the cause?

Regards, 

Konstantinos

It is not unusual. Internet sites are common sources for malware, the files are downloaded by the brower into a cache/temporary directory and become unavailable to upload/analysis later when the cache is flushed.

Hello @ckuwajima 

I believe this is not the case. 

The files are in a file server. The scan finds them but cannot fetch them for analysis. 

Their size is less than 50 MB 

So i cannot understand what is happening.

Hello @kostasthedelegate,
there can be several circumstances to generate such a message. First of all, the connector uploads files to the AMP cloud, if the file is requested from there. This means, the final decision for file upload is done by the cloud. Your file is a ZIP file and also already very close to the file limit.

Connector Limits:

• File Size: the connector processes file up to 50MB.
• The limit for file uploads is 20MB. This value is not configureable.

After a file is uploaded to the AMP cloud, the cloud itself forwards the file to TG cloud. The analysis failed information comes from Threat Grid cloud. If you do not have a full license for TG, you may open a TAC case to clarify.

Greetings,
Thorsten
