The availability and growing popularity of Voice Over Internet Protocol (VoIP) has spawned "vishing", a variation of phishing. Vishing couples the anonymity available on the Internet with the communications technology and social engineering needed to exploit victims.

The vishing scheme and scam is described in these webpages by the International Association of Chiefs of Police and the Federal Bureau of Investigation.

This is ugly and very real - you have to be on guard and careful. I never respond to PayPal or Amazon. However, I check my accounts to make sure they are secure and now I change my passwords regularly to avoid the scams.

Yep - Technology has opened all sorts of doors for the criminals. VOIP numbers can be changed on a regular basis as well and they are easy and cheap to get.

Thanks for reading and commenting. It is estimated that the old mail fraud (not wire fraud) scams were profitable if only one percent of those contacted responded and participated. Phishing, pharming, and vishing (these are wire frauds as well as other violations) multiply the number of victims because the number of contacts increase while the cost per contact decreases for the crook. Computer graphics quality (scanners, image editing software, etc.) has dramatically increased while coming down in price, so a legitimate institution's webpages can be easily and inexpensively counterfeited and used to suck in victims. The ease of changing VoIP numbers you mentioned as well as the anonymity the Internet offers makes the use of technology attractive to the crooks.
