PA will not update malware signature from sample malware files (

L3 Networker

 the customer want to test  pa wilfire  feature .

my test step:

1: from, download the sample malware.the traffice throught the pa

2: when we can find the  wildire log from firewall  and theck the log report ,know the  malware files sha256


log: 33, filename: wildfire-test-apk-file.apk
processed 120151 seconds ago, action: upload success
vsys_id: 1, session_id: 47055, transaction_id: 5
file_len: 1434514, flag: 0x801c, file type: apk
threat id: 52108, user_id: 0, app_id: 109
from to
SHA256: 2751671b591b6969b09f8c032cd89e6ae83a5f3ec819c8b923c673a6286cbec3


3:then wait 48 hours,we go to  threat db lookup the  sha256 value,but we don't find the sha256.

so I think that  PA will not update malware signature to antiivirus  from sample malware files( true  ?

step 4:

I set up a web server, put the malicious file (apk)on this web server, and then use another host to download the ake malicious file again through HTTP. The traffic passes through the pa firewall. Although the file has been recognized by the firewall's wilfarire function, I also waited 48 hours to update the AV feature library, but the firewall's threat protection does not recognize the malicious file, Therefore, I think PA does not update the signature of the sample to the AV feature library.

It should show up in the firewall logs, but might not show in the portal since its a known test file and they might not log it.



hi  Otakarklier:

  thanks you reply.

  It should show up in the firewall logs, -----which log ,threat log or wildfire log  ?

  when we do  test with step 4, the firewall don't block this malware files (apk) why ?
