Re: [asterisk-users] Hacking

John, There are a lot of factors at play for instance are you using a gui that has a known vlun? Is there mysql running on the box with a simple password? Perhaps they didnt hack your PBX but they comprised a SIP phone  and once they had the credentials  they made calls? Do you have a provisioning system? We have seen all of the above. Most of the compromises we are seeing these days is either via a Provisioning server or phones that are accessible on the internet with weak passwords  Regards, Dovid From: j...@xaccel.net Sent: June 16, 2019 18:37 To: asterisk-users@lists.digium.com Reply-to: asterisk-users@lists.digium.com Subject: [asterisk-users] Hacking Anyone know how someone can hack an asterisk box and register with every single account on the box. This box only has 3 accounts, with very complex passwords. Have VoIP blacklist setup and fail2ban…   The hackers were able to make 2 calls to Cuba before my alerting system texted me.   I am running asterisk 16.3 with PJSIP.   This is my only box open to the outside world, a requirement for this one customer. Looked into my logs… can't find anything out of the ordinary.     Any ideas ?       Contact:  <Aor/ContactUri..............................> <Hash....> <Status> <RTT(ms)..> ==========================================================================================     Contact:  12120001001/sip:12120001001@5.79.64.23:9227    ee80678930 NonQual         nan   Contact:  848842405/sip: 848842405@5.79.64.23:9227                  031ed703ba NonQual         nan   Contact:  848842405/sip: 848842405@5.79.64.23:9227                  031ed703ba NonQual         nan   Contact:  ghbhhm0000/sip:ghbhhm0000@5.79.64.23:9227      959fc8fbf4 NonQual         nan   Contact:  ghbhhm0000/sip:ghbhhm0000@5.79.64.23:9227      959fc8fbf4 NonQual         nan   Contact:  ghbhhm0000/sip:ghbhhm0000@5.79.64.23:9228      d7bf838918 NonQual         nan   Contact:  ghbhhm0000/sip:ghbhhm0000@5.79.64.23:9228      d7bf838918 NonQual         nan   Any helps is much appreciated.     John Bittner CTO 380 US Highway 46, Suite 500 Totowa, NJ 07512 Phone: 201.806.2602 x2405 Fax:       201.806.2604 Cell:       973.390.1090 www.xaccel.net   CONFIDENTIALITY NOTICE: This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information which should not be shared or forwarded.
