Toll fraud on poorly protected Asterisk servers seems to have mushroomed in the last 12 months. I constantly see evidence of scanning and brute force password guessing attempts on port 5060 of many different servers and PBX's.
If you operate a Trixbox or any Asterisk based PBX then you urgently need to review how secure it is and make sure you have not left any gaps in your defences. Failure to do so could leave you with an astronomical phone bill and very little, if any, redress.
Learn about the vulnerabilities and how to protect your Asterisk based PBX by reading my three part article:
How secure is your Asterisk PBX? Part 1
