Re: Company being War Dialed

The war dialing started last night and has continued throught the day.
They are being very noisy, staying on the line with a steady beep, beep,
beep long enough to leave a voice message.  The calling has occcured on two
different prefixes so I am concerned my company is being targeted.

Our local service provider's security and fraud team has not been able to
identify a single source of the calls.

? Bizarre.

We have recently done our own War-dail and feel we know all our modems are
secured correctly.

Any thoughts on additional steps I should be taking?

thanks

Make darn sure your voicemail passwords are good or you may get to
experience the fun of toll fraud. Any messages that say "Yes" or "Yes..
Yes.... Yes" are a good indication that toll fraud is about to happen (or
already has).
