“Locky” ransomware

[Wayne11]

Hi guys

I'm definitely not paranoid, but I'm a bit scared of the new "Locky" ransomware. Fortinet has published yesterday a blog post about Locky, but I can't find anything in the AV signature database nor in the IPS for this Locky bastard. Does anyone know which scan engine is able to detect Locky or Dridex?

Thx

Wayne

Does anyone know the update version this was pushed out in?  I am trying to narrow down in our manager the exact signature.  I read somewhere that it was under Application Control, but I was not able to verify it there.  Any help would be appreciated.

Hi all,

I cant find locky.botnet IPS signature in my IPS signature list. The latest update for IPS is 29/3/2016. How can I verify if that signature is installed or not. Thanks.

It's not available in the IPS list, it's listed under Application Control. Choose 'Application Override' within an AC profile and search for Locky.

Might be an easier way of doing this but here's what worked for me:

[ol]

Install letsencrypt on a box with tcp/80, tcp/443 open.

Temporarily point the DNS A record of your SSL VPN at the box you're going to run letsencrypt on.

Run letsencrypt-auto -d vpn.yoursite.com and when prompted choose the standalone server option.

Undo step 2 by pointing your DNS A record back at your SSL VPN IP

Grab your pems from /etc/letsencrypt/live/vpn.yoursite.com

[/ol]

FortiGate:

[ol]

System -> Config -> Certificates -> Import -> Local Certificate. Set type to Certificate. For certificate choose cert.pem and for key choose privkey.pem

VPN -> SSL -> Settings. Change Server Certificate.

Repeat process every 90 days

Here is the VPN Encryption Guide if you need any other configuration.
