7MS #459: Cyber News - Microsoft Exchange Makes the World Cry Edition

Happy mid-March! Our good pal Gh0sthax joins us today for another hot dish of cyber news! Stories include:

  • Microsoft Exchange cyber attack - Hacker News has a nice what we know so far story, but things have evolved really fast, so make sure you check Microsoft's primary advisory, the script to run on local servers and newer updates such as the recent one-click remediation for unsupported Exchange versions

  • SonicWall zero day - yuck, looks like the SonicWall troubles we talked about recently were a true zero day. In contrast to the Exchange story, it looks like SonicWall's official response offers (frighteningly?) little by way of logs and forensics to tell if you were truly popped. Either way, be sure to patch!

  • Hackers attempt to contaminate Florida town's water supply - the story itself is interesting, but the way it got picked up by some outlets seems to send the message of "TeamViewer = bad" but we think the true lessons learned here are:

    • Out of date and/or unsupported OS = bad
    • Weak credentials = bad
    • Connecting this type of equipment directly to the Internet instead of MFA + VPN = bad

CISA has a great breakdown of this incident as well.

7MS #147: DIY Hosted Mutillidae

In this episode I talk about how to build a cheap hosted Mutillidae server to safely hack away on while keeping other Internet prowlers out. Here are the basic commands to run to lock down the Digital Ocean droplet's iptables firewall: *Flush existing rules* **sudo iptables -F** *Allow all concurrent connections* **sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT** *Allow specific IPs/hosts to access port 80* **sudo iptables -A INPUT -p tcp -s F.Q.D.N --dport 80 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT** *Allow specific IPs/hosts to access port 22* **sudo iptables -A INPUT -p tcp -s F.Q.D.N --dport 22 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT** *Block all other traffic:* **sudo iptables -P INPUT DROP** *Provide the VPS loopback access:* **sudo iptables -I INPUT 1 -i lo -j ACCEPT** *Install iptables-persistent to ensure rules survive a reboot:* **sudo apt-get install iptables-persistent** *Start iptables-persistent service* **sudo service iptables-persistent start** *If you make iptables changes after this and they don't seem to stick, do this:* **sudo iptables-save > /etc/iptables/rules.v4** See this Digital Ocean article for more information.
