hello everyone. i am concerned about security to the PBX and i would like to discuss different fraud detection methods.

I worked on some ad data before and I found NYT article very biaised and not far from a fraud... Anyone knows if they got money from a - company - to play 'R'? Check out the title: R U Ready for R? Seems to me this title was stolen from XLSolutions www.xlsolutions-corp.com and they never mentioned XLSolutions in the article! They mentioned commercial R....never mentioned

Hi, Some days ago I spent about US$700,00 in a Tormenta III board in www.govarion.com. I used credit card. I didn't receive any answer for my emails and there is no telephone number to contact them.. Now, I'd like to cancel this order, because I couldn?t wait so long, and my credit card was billed. Is www.govarion.com a fraud ???? Does anybody know something about them ?? Thanks.

I?ve seen the following exploits of Asterisk / FreePBX boxes: 1) Default PlcmSpIp username and password for Polycom provisioning 2) Insecure SIP usernames and secrets 3) FreePBX GUI accessable from the internet 4) OS remote exploit (maybe ssh/ssl exploit) Mitigation options: 1) Don?t use an easy to guess or default password on provisioning servers. 2) Use secure secrets. Users never

I charge my customers through PayPal, but recently faced a fraud which previously had only heard about. Somebody registered a few accounts, paid online with paypal (as my service is only prepaid) and started making expensive long distance calls. In fact the IP registering the accounts was from Florida, and IPs making calls were from Africa. After about 20 minutes the first payment was reversed.

Did you have a look at the phone it self already? Is call forwarding activated or something and can you call the phone/extension from externally? I have seen this in the past where an employee enabled call forwarding on the phone and once at home he or family called the phone which forwarded the call to abroad. Good luck. Michel.

Hi, Embarrassed as I am to write this, I am hoping for some advice. One of our very first PBX installs, now six years old, was "taken advantage of" over the past few weeks. A victim of sipvicious, I assume, that managed to guess one of the SIP passwords. 4000 calls to various middle eastern destinations have been placed, which ended up being sent over our customer's PSTN

Subject says it all... A Simple Asterisk Based Toll Fraud Prevention Script http://www.infiltrated.net/asterisk-ips.html Ramblings for admins/engineers to think about. Doesn't have to cost you umteen thousand dollars for stuff like IPS/IDS. Although a little on the crude side, quite effective. If you care to dabble with MySQL you can create quite an impressive hosts based IPS that is custom

It's very unlikely that this was an employee calling Mom for 66 hours (I'm assuming these calls appeared on a single bill). It's also unlikely that someone "inside" would benefit financially from making these calls. (Follow the money!) Don't discount the possibility that you've overlooked something in the firewall. Meanwhile, does the client need to do international

You don't mention if the phone is remote, or local. Although you do mention it had a default user/pass. If the UI of the phone was/is accessible from the I'net, the GUI does have the ability to place a call from it, that is one way the calls could have been placed.

Hi, in case, anyone is interested... I have started compiling a blacklist of hosts and networks from which SIP fraud attempts occur. My criteria currently are: To block an IP: - Minimum 3 attacks within one week from the same IP To block a network: - Attacks from minimum 3 IPs from that network within 2 weeks Common criteria: - Provider does not react to complaints OR - Provider sends autoreply

The Authenticate application will do this for you. https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Application_Authenticate You can either give it a single PIN to use for all calls, Authenticate using a value in the Asterisk Database, Or use a plain text file for the PIN's On Mon, Jul 6, 2015 at 2:43 PM, Motty Cruz <motty.cruz at gmail.com> wrote: > Hello All, > >

Sadly I am still seeing a loss of communication. I will check the device number to see if it has changed. Not sure what else to look at. I guess I could create a corn job to restart the driver multiple times a day. ---- On Fri, 22 May 2020 00:44:04 -0400 David Zomaya<David_Zomaya at tripplite.com> wrote ----Did it stay stable this time?

The loss of communication to USB devices has been discussed before on this list. I do not recall the particulars (& thus do not know if they're relevant to the situation at hand), but it seems to me that it was ultimately related to the USB libraries being used. Charles Lepple was instrumental in the thread I'm thinking of. Roger's suggestion of a more intelligent cron job sounds
