My monthly reminder that you can read what @sandrogauci / @enablesecurity writes or **wish you had**.
Also, SIP ALG is still a bad idea.

Time for me to say... "There are those who read what @sandrogauci and @enablesecurity write and those who wish they had."
Also, very honored to have #APIBAN make the newsletter -- in a good way. ;)

Looking forward to talking about #APIBAN tomorrow.

Big thanks to Lorne Gaetz for his help testing apiban-fail2ban on FreePBX 16/17. His feedback has allowed for script improvements and better documentation.
-
Added a new simple, lazy install script for the apiban-fail2ban client. The script is geared towards freepbx using "asterisk-iptables" as the jail.

Just finished the bi-weekly #FreeSWITCH open hours/community call.
I like to join when I can and do want to give props to the SignalWire team for reaching out to the community like they do.

How batshit crazy is Palo Alto spamming of #SIP servers?
The 198.235.24.0/24 currently has **102** active IP addresses sending unwanted SIP traffic.
Horrible.

Continued exploit of open relay #SIP REGISTER attack occurring, with increased activity over the last 12 hours. Most IP addresses have already been seen, and vast majority of systems (doing the relaying) are Ingate Systems (the SIParator SBC). No response from Ingate.
Help protect your systems with #APIBAN (https://apiban.org)-- a free service, thanks to our sponsors.

Last night saw another round of #SIP open relay attacks. Most of the relaying appears to have been Ingate SIP Trunking Solutions' SIParator product.
APIBAN (https://apiban.org) is a free service (thanks to our sponsors) that you can implement on most *nix systems, some firewalls, etc to help protect yourself from these types of #VoIP attacks.
For more information on SIP open relay attacks, there's a great article from Ivan Kwabena Nyarko:

I really like the GitHub sponsor feature... nice, simple way to help an open source project you're using keep on keeping' on (as Joe Dirt would say).
For example. I love simplecss.com... and @kev made it easy to sponsor.
(By the way... you can sponsor #APIBAN if you're finding it helpful, or even if you're not... you can still sponsor)

Seeing a huge spike in REGISTER traffic attacking SIP servers out there. Many seem to be using Ingate SIParator SBC as an open relay.
APIBAN (https://apiban.org) is a free service to help protect you from these attacks.
Also, a good analysis of the last attack (written by Ivan Kwabena Nyarko) can be found here:
