It runs on a separate port (8112 by default), for a total of three.

"deluge-web -fork" is a web gui to add/remove Torrents.

Once a Torrent is added it needs two ports to operate (1 Inbound + 1 Outbound). "deluged" runs as a local daemon on the server. I threw in an application like Deluge because I can't get my head around the firewall logic. All Inbound+Outbound traffic flows over one port after the connection is established - easy enough.Ĥ. Am I correct in assuming that it would be wise to NOT use UFW to configure my firewall and instead rely strictly on iptables? I believe this to be true because knockknock will need custom iptable entries to work.ģ. Has anyone on the forums attempted to setup port knocking with knockknock before?Ģ. Or, I can use knockknock and hide SSH and Deluge but need to keep 1outbound+1inbound tcp port open for deluge xfers (or use knockknock-proxy). I think my options are I can firewall the server, open SSH port and keep it visible, and get to the deluge by going to localhost:8112 after a ssh -D $someport.

Protect privileged accounts with all the means available, MFA for Admins (at least), just in time administration for these accounts where available, see options here - Securing privileged access in Azure AD.Īs Tony Redmond revealed via an Ignite stat "only 0.73% of Office 365 administrative accounts are protected by multi-factor authentication", which is disappointingly low and make attacks like this, that bit easier to pull off.I'm trying to "hide" the fact that SSH + deluge are running when port scanned.

Look at the Client External Rules Forwarding Block that Secure Score can implement easily on your behalf, that stop email rules forwarding outside the organization.

Minimize the use of these ‘non-human’ system accounts, give them no more rights than they need, track their usage and retire them as systems are no longer needed.

Don't skimp on security with service, system, middleware, automation accounts etc., have strong measures in place to protect them.

Here are a few tips, from my perspective that makes some sense:

Once an account has been comprised, an inbox rule is setup for data exfiltration, then the attack tries to spread via a phishing campaign using the infected inbox.

The attack is very low key and designed to avoid detection. Examples given include service, automation and internal tool accounts as well as distribution lists and shared and delegated mailboxes.

Attacks are targeted rather than a mass strike, with system accounts the aim, as these are typically are less well protected like with a poor password policy or lacking MFA etc, yet these accounts often have elevated rights.

Apparently, the KnockKnock campaign started in May 2017 and is ongoing, reportedly widespread though the bulk of the activity was from June to August.

Not to sensationalize any reports but I think it's worth reviewing some of the outcomes to highlight the methods involved, which I have tried to summarize below along with a few best practices that can disrupt much of this. It's been reported there is an ongoing cyber attack against Office 365 Exchange Online mailboxes called KnockKnock.
