Cortex-XDR hash verdict

Hi Team,

Our cyber security department has shared few hashes and asked to check the these hashes verdict? How to check a hash is malware or benign? how to perform this on cortex xdr portal?

Your best bet is to use the WildFire portal to do a hash lookup.

https://wildfire.paloaltonetworks.com/wildfire/reportlist/Manual

Keep in mind, this only shows results for files known by WildFire. If it is as unknown file, Local Analysis can still provide a verdict. The only downside is, there is no way to know what scoring Local Analysis will give a file until the agent has a chance to see the actual file.

wildfire only showing the result of files were forwarded from our security devices.its not showing the global database over there.

for eg: 7e27e33ec3df0ea9e89d32b050f1f0a211e3764818b9cad19308b8c954a02f03

Hello @Marsooq_A ,

You can check the coverage of the hashes from threatvault.paloaltonetworks.com

If the hashes show up as malicious in VT and other trusted resources, do go ahead and blacklist the files.

If you raise a case for hash coverage check, the sample/file will be asked of you by the team; for the hashes which don't show up in wildfire db or threatvault.
