In one instance, traffic from an Emotet-related IP attempted to connect to a suspected compromised site over port 445, possibly indicating the use of Server Message Block exploitation frameworks along with Emotet ( Exploitation of Remote Services ). Traffic to known Emotet-related domains or IPs occurred most commonly over ports 80, 8080, and 443.

Mozilla/4.0 (compatible MSIE 7.0 Windows NT 6.1 WOW64 Trident/7.0 SLCC2. Possible command and control network traffic involved HTTP POST requests to Uniform Resource Identifiers consisting of nonsensical random length alphabetical directories to known Emotet-related domains or IPs with the following user agent string ( Application Layer Protocol: Web Protocols ).

Emotet used compromised Word documents (.doc) attached to phishing emails as initial insertion vectors. CISA observed Emotet being executed in phases during possible targeted campaigns. During that time, CISAвЂ™s EINSTEIN Intrusion Detection System, which protects federal, civilian executive branch networks, has detected roughly 16,000 alerts related to Emotet activity. Since July 2020, CISA has seen increased activity involving Emotet-associated indicators.

Additionally, Emotet uses modular Dynamic Link Libraries to continuously evolve and update its capabilities.

Setup the appropriate DNS/CNAME record ( -> ).Emotet is an advanced Trojan primarily spread via phishing email attachments and links that, once clicked, launch the payload ( Phishing: Spearphishing Attachment, Phishing: Spearphishing Link ).The malware then attempts to proliferate within a network by brute forcing user credentials and writing to shared drives ( Brute Force: Password Guessing, Valid Accounts: Local Accounts, Remote Services: SMB/Windows Admin Shares ).Д®motet is difficult to combat because of its вЂњworm-likeвЂќ features that enable network-wide infections. Mailu setup utility generates a safe IPv6 ULA subnet by default. However exposing all containers to public network neither. We know that nat-ing is not advised in IPv6,

So, how to make it work? Well, by using docker-ipv6nat! This nifty container will set up ip6tables, Incoming connection to the SMTP container will bypass the authentication stage by the front container regardless of your Still rewrite any incoming IPv6 requests to an IPv4 address, which is located inside the trusted network. If you enabled IPv6 inside the setup assistant (and fixed the ports to also be exposed on IPv6) Docker will the SMTP container without furtherДЄuthentication. Mailu has its own trusted IPv4 network, every container inside this network can use e.g. Okay, but I still want to use IPv6! Can I just use the installers IPv6 checkbox? NO, YOU SHOULD NOT DO THAT! Why you ask? Robbert Klarenbeek (docker-ipv6nat author) Source IP addresses are rewritten, making it completely unusable for many purposes, e.g. It can use a lot of RAM ( docker/docker#11185) ( docker/docker#14856) and has various issues, like: The userland proxy, however, seems to be on its way out (which, for now, is enabled by default in Docker) Published ports wonвЂ™t work on IPv6, unless you have the userland proxy enabled Still an administrative hassle ( docker/docker#13481) The alternative is to assign a specific IPv6 address to each container, Reachable by everyone, if no additional filtering is doneД«y default, each container gets a random IPv6, making it impossible to do properly do DNS Giving each container a publicly routable address means all ports (even unexposed / unpublished ports) are suddenly See the various GitHub issues linked below: Much discussion is still going on as to how IPv6 should be used in a containerized world It was added later and, while it has come a long way, is still not as usable as one would want. Unfortunately, initially Docker was not created with IPv6 in mind. Please check the message recipient and try again even though the sender is legitimate?
