Detecting / mitigating Cryptolocker

[Tuomo]

Hello,

my customer is worried about Cryptolocker infections in the network - CryptoLocker Ransomware Infections | US-CERT. Do you happen to have any best practices or general tips on how to use PAN tools to detect and prevent Cryptolocker from infecting hosts?

Cheers,

Tuomo

There are some preliminary notes at the research center saying to monitor crilock events.

And of course to make sure smtp is locked down for outbound access.

Thanks for posting this. How do I confirm that the PA is scanning for these viruses?

Hi

I'm thinking that I have properly configured security policies against Cryptolocker.

According to above link:

     URL filtering policies in combination with File Blocking policies (block all files from unknown domains) adds an additional layer of protection, keeping the payload from being delivered.

How to realize that?

Could someone share their settings?

With regards
